Best Extension Cords in Australia (2026): Household, Caravan and RCD Leads

What is the best extension cord in Australia?

The best extension cord for most Australian homes among our eight cards is the QIUCABLE 5m AU 3 Prong Extension Cable. Its listing says SAA certificate for AUS/NZS Market, 10A/250V and 5M length, and it shows 4.9 stars from 9 ratings, a small sample. For caravan sockets choose a 15A lead instead.

The tricky part is matching the amp rating and the plug to the job. The wininks listing gives 2400 watts, and the two 15A leads, the Ultracharge 15A 20m and the Companion 15A 10m, give 3600 watts. The Companion listing says a 15A socket can safely accept both 10A and 15A plugs, while a 15A plug requires a 15A socket. This guide sorts eight cards by the job you are buying them for and reports what each Amazon AU listing says.

We are a small Australian team. We research listings, owner ratings and the makers' own bullet points rather than running a test lab, so treat this as a careful buying guide, not a bench test. Every rating, count and spec below comes from the Amazon Australia listing, and the method section says how we checked.

Quick answer: which extension cord should you buy?

Buy the QIUCABLE 5m AU 3 Prong Extension Cable for everyday 10A use: it shows 4.9 stars from 9 ratings and its listing says SAA certificate for AUS/NZS Market. Choose the Ultracharge 15A 20m or the Companion 15A 10m for 15A sockets, the Ultracharge inline RCD lead for a safety switch, and the wininks 5 pack for tight gaps.

• Everyday 10A cord: QIUCABLE 5m AU 3 Prong Extension Cable. SAA certificate for AUS/NZS Market, 10A/250V, 4.9 stars from 9 ratings.
• Flat plug, indoor: Brennenstuhl 10m Flat Plug Extension Lead. 4.8 stars from 317 ratings, listed for indoor use, but its listing shows no Australian plug text.
• Tight gaps: wininks 20cm Short Extension Lead 5 Pack. A 5 pack of 20cm leads, 4.5 stars from 23 ratings.
• Safety switch: Ultracharge inline RCD lead, 2m, with a rated leakage tripping current of 30mA, 4.7 stars from 23 ratings.
• 15A, 20m: Ultracharge 15A 20m Contractor and Caravan Lead, 4.8 stars from 20 ratings.
• 15A, 10m: Companion 15A 10m Caravan Extension Lead with integrated LED indicators, 4.0 stars from 5 ratings.

These are the six leads we could buy, and each card shows the rating and count from its Amazon AU listing. Match the listed amps and watts to your appliance label, then choose the shortest length that reaches.

How do these extension cords compare at a glance?

The QIUCABLE 5m lists an SAA certificate and 10A/250V, the Brennenstuhl 10m is the flat plug indoor lead, and the two 15A leads list 3600 watts. The table below sets length, listed rating and the feature that decides each lead, using the Amazon AU listings. The cards through the guide carry each lead's star rating and rating count.

How we checked these extension cords

We are an aggregator and editorial team, not a testing lab. We do not plug leads into a wattmeter or pull them apart. We read the Amazon AU listing for each lead, including the title, bullet points, product information table and description, and noted the seller, rating and rating count shown on it. Specs come from the maker's bullet points and the product information on each listing; we saved no separate maker page or manual for these leads. Here is what we looked at:

• Ratings and counts. Each card shows the star rating and the number of ratings from its Amazon AU listing. The QIUCABLE has 9 ratings and the Companion has 5, so treat those two averages as early signals.
• Plugs, voltage and certificates. We record what each listing says about its plug, voltage and any standard or certificate, and where a listing says nothing we say so on the card.
• Amp rating and length matched to a job. We sorted leads by listed amps, watts and length, so a caravan buyer and a home office buyer end up in different sections.
• Listed safety features. We note indicator lights, RCD protection and cable core size when a listing states them, and we do not rank a lead on a feature its listing does not state.
• Stock. We checked the Amazon AU stock feed for every lead. A lead that Amazon showed as unavailable keeps its card with a dated note and is not recommended.

Last checked: 19 October 2026.

How big an extension cord do you need?

Lengths on this page run from 20cm to 20m. The leads we could buy list a 20cm lead, a 2m RCD lead, a 5m lead, two 10m leads and a 20m 15A lead. Pick the shortest length that reaches, and match the listed amps and watts to the appliance label.

What is an extension cord, and is it the same as an extension lead?

An extension cord, called an extension lead in many Australian searches, has a plug on one end and a socket on the other. The QIUCABLE listing calls this Male to female socket. The wininks 10A lead lists 2400 watts, the QIUCABLE lists 2400 watts in its product information while its description says 2500 Watts, and the 15A leads give 3600 watts.

What is the difference between a 10A and a 15A plug?

The Companion listing explains the difference: on a 15A plug the active and neutral pins match a 10A plug, but the bottom earth pin is much wider, approximately 9mm versus 6.3mm. A 15A socket can safely accept both 10A and 15A plugs, while a 15A plug requires a 15A socket.

Can you use an extension cord for a fridge, washing machine or pressure washer?

The QIUCABLE listing names household fridge converaion (the listing's spelling) among its designed uses, and its description lists pressure washers and cleaning equipment among its outdoor applications. One wininks review says the reviewer's washing machine plug was short by a few cm. Check each appliance's rating label against the lead's listed watts, and follow the appliance maker's manual. If you roll a washer out on a wheeled washing machine stand with locking brakes to reach the power point, leave enough slack in the lead.

Best overall: QIUCABLE 5m AU 3 Prong Extension Cable

The QIUCABLE 5m AU 3 Prong Extension Cable leads this page because its listing states an AUS/NZS 3 Prong Plug with a male to female socket, a cable spec of H05VV-F 1.0mm2/3C 10A/250V with 100% copper wire and 5M length, and a certificate line reading SAA certificate for AUS/NZS Market. It shows 4.9 stars from 9 ratings, a small sample, so treat the score as an early signal. Amazon shows it as shipped from Amazon and sold by QIUCABLE.

The product information table lists 250 Volts, 10 Amps, Plug Type Type I, 5 Meters and China as the country of origin, and it gives 2400 watts, while the description lists Max. Power Rating: 2500 Watts, so use the lower figure. The bullets say it is designed for use with a UPS and power conditioners for studio equipment, household fridge converaion (the listing's spelling) and home appliance electrical equipment, and give a 12 month warranty.

The title says Outdoor 10A 250V and the description says Usage: Indoor and Outdoor, but the title, bullets and product information give no IP rating, so we cannot say how well the plug and socket resist water. The description also says to always use it with an appropriate residual current device (safety switch) for outdoor applications, which is the job of the Ultracharge inline RCD lead below. If you are stringing up Christmas lights, check the lights' own label against the 10A and 250V this lead lists.

What does the QIUCABLE description tell you to do with it?

The description carries a safety list. It says to always fully unwind the extension cord before use to prevent overheating, keep the total power draw within the 10A (2500W) rating, and keep the female socket connection elevated and protected from moisture for outdoor use. It also says not to run cables under carpets, rugs or heavy furniture.

The list continues with inspecting the cord regularly, keeping it away from heat sources, sharp edges and trip hazards, unplugging it when it is not in use and storing it in a dry location. The description's indoor applications include home entertainment systems, computer and office equipment and kitchen appliances, and its outdoor applications include lawn mowers and garden tools, outdoor lighting and decorations, and camping and caravan power connections. Check the label of any tool before you rely on that list.

The description also says the 1.0mm core size is specifically chosen to minimise voltage drop over the 5 metre length and lists the jacket as Heavy Duty Weather Resistant PVC. Those are the seller's statements, and the listing gives no IP rating.

Flaws but not dealbreakers

Only 9 ratings stand behind the 4.9, so the average could move. The listing contradicts itself on power, with 2400 watts in the product information and 2500 Watts in the description, and it gives no IP number. At 5 metres it will not stretch across a big yard.

Brennenstuhl 10m Flat Plug Extension Lead for indoor flat plug use

The Brennenstuhl 10m Flat Plug Extension Lead is a white indoor lead with an extra flat angled plug. Its bullets describe an extra flat earthing contact angle plug and earthing contact coupling made of plastic with 10 m of H05VV-F 3G1.5 cable, and a fold out handle that allows easy unplugging of the flat plug from the socket. It shows 4.8 stars from 317 ratings. At the 19 October 2026 check it was sold by Amazon Germany, with a notice that Imports from Germany may differ from local products.

The listing shows no Australian plug text. The bullets describe an earthing contact angle plug, and the product information gives Plug Type Type A, 230 Volts, 16.3 Amps and 3750 watts, so we cannot say it fits an Australian socket. The title says Indoor Use, the description says For indoor use, IP 20, and the product information says Not Water Resistant.

This is the flat plug card on this page, and the bullets call the extension cable ideal for practical and space saving use indoors. White is the colour in the title, and the bullets describe the plug and coupling as sturdy plastic. Keep it out of the weather and confirm the plug against your socket before you order.

The listing's box contents line reads 1 x extension cable with fold out handle, and its bullets add increased touch protection to the description of the 10 m 3G1.5 cable. Beyond the plug description, cable and indoor wording, the listing we saved states no Australian plug text and no certificate, and its product information says Not Water Resistant.

Skip it if you need a lead whose listing states an Australian plug, a certificate or outdoor use. The saved listing states none of those, so it suits a buyer who has confirmed the plug against their socket and wants a flat plug lead for indoor use.

Flaws but not dealbreakers

Because the listing shows no Australian plug text, confirm the plug before you buy; we cannot say it fits an Australian socket. It is listed for indoor use and is not water resistant.

wininks 20cm Short Extension Lead 5 Pack for tight gaps

Sometimes you do not need a long cord at all, you need 20 centimetres. The wininks listing is for a 5 pack of 20cm leads: its title reads Australian 3 Pin Plug 20cm Extension Lead Cable Male to Female Short Power Cords 1.0mm2/3C 5Pack, and the product information lists a unit count of 5. The bullets describe a standard Australian 3 pin plug and socket, compliant with AS/NZS 3112 standards and rated for 10A/240V, with 3 core 1.0mm² wiring. It shows 4.5 stars from 23 ratings.

The wininks description goes into construction. It lists fully moulded male and female connectors with integrated strain relief, a flame retardant PVC jacket and black as the colour, and the bullets call the 3 core 1.0mm² wiring durable enough for commercial or light industrial use. Those are the listing's words, not something we tested.

The description lists these uses: creating extra clearance for bulky power adaptors and wall warts, extending reach to awkwardly positioned wall sockets behind furniture, and organising cable management behind entertainment units and desks. Its Please Note lines say to keep the total power draw of connected devices within the 10A (2400W) rating, to use it indoors in dry environments only, and to discontinue use immediately if damage is found.

The bullets suggest tidy cable management in server racks, behind desks and in entertainment centers, and name computer cabinets, desks with multiple appliances and lab equipment as places where a standard power cord is too long. One review on the listing says the reviewer's washing machine plug was short by a few cm. The product information lists Indoor and a 20 Centimeters item length.

Being so short is its main limitation: it bridges a small gap and nothing more. The listing is not consistent about its details. The title and the product information say 5 pack, but the description says Quantity: 1 Cable per Pack, and the bullets give 10A/240V in one place and 10A/250V in the cable spec line. The product information lists 15 Amps for amperage and 10 Amps for input current, so we use the 10A from the bullets.

Flaws but not dealbreakers

The description says it is for indoor use only in dry environments. It is short by design, so it solves one narrow problem rather than being a general purpose lead, and the pack size is described two ways, so check the quantity on the listing before you order.

Is a 20cm extension cord worth buying?

It solves one narrow problem: a bulky plug that blocks the wall socket or a socket just out of reach. The wininks description lists creating extra clearance for bulky power adaptors and wall warts, and extending reach to awkwardly positioned wall sockets behind furniture. The listing shows 4.5 stars from 23 ratings.

Check three things first. The title and product information say 5 pack while the description says Quantity: 1 Cable per Pack, the bullets say 10A/240V while the cable spec line says 10A/250V, and the description says for indoor use only in dry environments. Its Max. Power Rating line reads 2400 Watts.

Sansai 20m Heavy Duty Extension Cord

The Sansai 20m Heavy Duty Extension Cord could not be bought on 19 October 2026, so we do not recommend it. Amazon showed the listing as currently unavailable with no add to cart. The listing's bullets give Power Input 250V ac 10amp and Power Handling 2400Watt Max for Heavy Duty Indoor & Outdoor use, and its title adds a light indicator.

The listing also gave 20 Meters as the item length and 4.7 stars from 23 ratings. If you run a lawn mower or other garden gear from any long lead, compare the gear's own wattage label with the lead's listed watts first.

Its listed 10amp and 2400Watt Max matched the other 10A leads on this page rather than the 15A caravan leads. For a 15A lead, see the Ultracharge 15A 20m and Companion 15A 10m cards below.

The GENTRAX 3500W listing names dual 240V/15A outlets, covered in our inverter generators with 15A outlets guide.

Flaws but not dealbreakers

With no add to cart in the capture there is nothing to buy here today. If Amazon lists it again, read its bullets for the 250V ac 10amp and 2400Watt Max wording before you rely on it.

Ultracharge inline RCD safety switch lead, 2m

The ULTRACHARGE Lead with Inline RCD Safety Switch 2M UR240RCD has an inline RCD (residual current device, the same thing as a safety switch) in the lead. Its bullets give 10A 230 to 240V 50Hz AC, a 3 core 1.5mm heavy duty cable, a rated leakage tripping current of 30mA, a maximum tripping time under 0.1s and 2M of length. The listing shows 4.7 stars from 23 ratings.

The description includes the line Approved. 2 Metre heavy duty yellow cord, which names no standard or certificate number, so we claim none for it. It also calls the lead a heavy duty safety extension lead with an in line Residual Current Device (RCD) safety switch for protection against electric shocks.

The listing's description calls it a heavy duty safety extension lead with an in line Residual Current Device (RCD) safety switch for protection against electric shocks. Plug the lead in first, then plug your appliance into it, and the switch sits between the wall and the appliance. One review on the listing says it was bought for an iron because the iron's cord was not long enough.

At 2 metres it is a short lead by design. Its product information lists 10 Amps for amperage but 15 Amps for input current, and the bullets say 10A, so check the rating against your tool before you rely on it. The product information also lists China as the country of origin.

Flaws but not dealbreakers

At 2 metres it does not reach far on its own. The listing gives two different current figures, so check the rating against your appliance label first.

What does an RCD on an extension cord do?

The Ultracharge description calls the lead a heavy duty safety extension lead with an in line Residual Current Device (RCD) safety switch for protection against electric shocks. Its bullets give a rated leakage tripping current of 30mA and a maximum tripping time under 0.1s on a 2M lead, with 3 core 1.5mm heavy duty cable.

The lead is listed for 10A 230 to 240V 50Hz AC, so it is a mains lead, and its product information lists China as the country of origin. The description we saved names no standard or certificate number beyond the line Approved. 2 Metre heavy duty yellow cord, so check the plug and packaging yourself. Plug the lead in first, then plug the appliance into it.

Of the leads we could buy it is the only card whose bullets give a tripping time, and apart from the 20cm wininks it is the shortest.

Ultracharge 15A 20m Contractor and Caravan Lead

The Ultracharge Contractor/Caravan Suitability 15A Lead, 20 m Length is listed as a heavy duty mains 20 meter extension lead with a 15A plug and socket used for 15 amp connections. The bullets add a thick orange/black flexible chord and an internal LED to indicate live power, and say it is commonly required for connecting Caravans and other RVs. It shows 4.8 stars from 20 ratings. The featured offer on this listing was sold by Amazon Resale and fulfilled by Amazon.

The description adds that the lead is commonly required for connecting caravans and other RVs to mains connections in caravan parks, and its specifications give Length: 20 meter, Voltage: 240V, Max Current: 15A and Max Power: 3600W. The title gives the length as 20 m.

The product information lists 3600 watts, 15 Amps, 240 Volts and Australia as the country of origin, and the description gives Max Current: 15A and Max Power: 3600W. A 15A plug requires a 15A socket, so check the inlet on your van or site post before you buy; the Companion listing explains that a 15A socket accepts both 10A and 15A plugs.

The product information lists its item length in centimeters, which matches the 20 meter title. Its Plug Type field says Type B and its Power Cord Prong Count field says 2, which sits oddly beside the active, neutral and earth pins that the Companion listing describes for a 15A plug, so we make no claim about the plug shape beyond the bullets' 15A plug and socket. If you want a shorter 15A option, the Companion lead below is a 10 meter alternative.

Flaws but not dealbreakers

It shows 20 ratings, fewer than the Brennenstuhl's 317 and the wininks' 23. The Plug Type and prong count fields conflict with the bullets, as noted above. A 15A plug requires a 15A socket per the Companion listing, so it is the wrong lead for a 10A only socket.

SAS Electrical 15m 10A Heavy Duty Extension Lead

The SAS Electrical 240V 10Amp Heavy Duty Extension Lead, Orange, 15 Meter Length could not be bought on 19 October 2026, so we do not recommend it. The Amazon AU feed returned no row for it that day and its listing could not be loaded, so we hold no bullets or product information for it.

Because no listing text was saved, this page makes no claim about its plug, certificate, rating count, material or maker. The only figures we hold are the 240V, 10Amp and 15 Meter Length in the card title. If Amazon lists it again, read the listing itself before you rely on it.

A corded belt sander or any other tool lists its own wattage on its label, so compare that label with the listed watts of whichever 10A lead you buy.

Flaws but not dealbreakers

There is no saved listing to weigh and the lead could not be bought, so there is nothing to compare it on today.

Companion 15A 10m Caravan Extension Lead

If 20 metres of caravan lead is more than you need, the Companion 15A 10m is the shorter option. The bullets list a bright orange cable, a clear plug and 15 amp socket with integrated LED, and a wide blade earth terminal compatible with 15A outlets, and the product information lists 3600 watts. It shows 4.0 stars from 5 ratings. The featured offer on this listing was sold by Amazon Resale and fulfilled by Amazon.

The bullets also say it is designed to handle high currents while providing resistance to damage from wear and tear, a claim we have not tested, and that its clear plug and 15 amp socket carry integrated LED for power status monitoring.

The bullets say it suits caravan parks and camping locations and give a 10 meter cable length. They also explain the plug: the active and neutral pins match a 10A plug, but the bottom earth pin is much wider, approximately 9mm versus 6.3mm, and a 15A plug requires a 15A socket.

We will be straight about the rating: 4.0 stars from 5 ratings is the lowest average among the cards we captured, and it rests on very few ratings, so treat it as an early signal. Check your van or site inlet before you buy. If your site posts are often far away, the 20 meter Ultracharge above is the longer option.

Flaws but not dealbreakers

The 4.0 stars come from only 5 ratings, so the average could move, and a 15A plug requires a 15A socket, so verify your inlet first.

Which extension cord suits which job?

Match the job to what the listing states. The QIUCABLE lists SAA certificate for AUS/NZS Market and 10A/250V for everyday use, the wininks lists 20cm for gaps behind furniture, the Ultracharge RCD lead lists 30mA leakage tripping, and the two 15A leads list 3600 watts for caravan sockets.

Which extension cord suits a caravan?

Our caravan cards are the Ultracharge 15A 20m, which its description says is commonly required for connecting caravans and other RVs to mains connections in caravan parks, and the Companion 15A 10m, whose bullets list suitability for caravan parks and camping locations. Both list 3600 watts, and a 15A plug requires a 15A socket.

The evidence behind them differs: the Ultracharge shows 4.8 stars from 20 ratings and the Companion shows 4.0 stars from 5 ratings. The Ultracharge product information gives Australia as the country of origin, while its Plug Type and prong count fields conflict with its bullets, so read its card before you rely on it.

How do the two 15A caravan leads compare?

Both list 15A, 3600 watts and an LED. The Ultracharge is 20 meters with a thick orange/black flexible chord, and the Companion is 10 meters with a bright orange cable and a wide blade earth terminal. Their ratings rest on very different counts.

How do the three 10A extension cords compare?

Three 10A leads can be set side by side. The QIUCABLE is the 5 metre cord, the wininks is the 20cm five pack and the Ultracharge is the 2 metre lead with a built in RCD. Their certificate wording differs, so read the line in each listing rather than assuming the same approval.

Can you use an extension cord outdoors?

It depends on what the listing states. The QIUCABLE title says Outdoor and its description says Usage: Indoor and Outdoor, but the listing gives no IP rating. The Brennenstuhl and wininks listings say indoor use. The Companion bullets describe a bright orange cable for easy identification in outdoor environments.

For outdoor use the QIUCABLE description says to keep the female socket connection elevated and protected from moisture where possible, and to always use a residual current device (safety switch). Treat those lines as the seller's instructions and follow your appliance maker's manual as well.

Which extension cord suits a pressure washer or an iron?

No listing here rates a lead for a named appliance. The QIUCABLE description lists pressure washers and cleaning equipment among its outdoor applications, one review on the Ultracharge RCD listing says it was bought for an iron because the iron's cord was not long enough, and one wininks review mentions a washing machine plug short by a few cm.

Those are a seller list and two reviews, not rating statements for your appliance, so check the appliance label against the lead's listed watts.

What safety lines do the listings give?

The longest safety lists sit in the QIUCABLE and wininks descriptions. Both say to stay within the rated load, to inspect the cord and stop using it if damage is found, and not to connect multiple extension cords in series. The QIUCABLE adds unwinding the cord, keeping the socket elevated outdoors and not running it under rugs.

What do the extension cord listings leave unsaid?

Every listing on this page leaves something to check. The QIUCABLE shows 2400 watts in one place and 2500 Watts in another, the Brennenstuhl shows no Australian plug text, the wininks calls itself a 5 pack and a 1 cable pack, and the Ultracharge leads show conflicting current or plug fields.

We report each conflict as the listing shows it. Confirm the figure that matters to you on the product page before you order, and check the appliance label against the lower watts figure when two are shown.

How many ratings stand behind each extension cord?

The counts differ a lot. The Brennenstuhl shows 317 ratings, the wininks and the Ultracharge RCD lead show 23 each, the Ultracharge 15A lead shows 20, the QIUCABLE shows 9 and the Companion shows 5. A high average on a low count can move, so read the count beside the stars.

The stars are 4.8 for the Brennenstuhl, 4.5 for the wininks, 4.7 for the Ultracharge RCD lead, 4.8 for the Ultracharge 15A lead, 4.9 for the QIUCABLE and 4.0 for the Companion.

How long an extension cord do you need?

The lengths on these cards are 20cm, 2m, 5m, 10m and 20m. The QIUCABLE description says its 1.0mm core size is specifically chosen to minimise voltage drop over the 5 metre length, and the Companion bullets say its 10 meter cable length provides flexibility and reach for various power connection needs. Pick the shortest length that reaches your appliance.

What should you look for in an extension cord in Australia?

Match four things: amp rating, length, the plug and certificate wording in the listing, and safety features. Start with the amp rating: the wininks lists 2400 watts for 10A, the QIUCABLE lists 2400 watts in its product information (its description says 2500 Watts), and the 15A leads list 3600 watts. Then pick the shortest length that reaches and read each listing's own plug and certificate lines.

How many amps do you need, 10A or 15A?

The wininks listing gives 10A and 2400 watts, and the Ultracharge 15A and Companion listings give 15A and 3600 watts. The Companion listing explains that a 15A socket can safely accept both 10A and 15A plugs, while a 15A plug requires a 15A socket. Check your appliance label and the socket before you choose.

How long should the lead be?

As short as the job allows, because spare cable is something to coil and trip over. The leads on this page are listed at 20cm, 2m, 5m, 10m and 20m, and the size table above shows each one. The QIUCABLE description's safety instructions say to always fully unwind the extension cord before use to prevent overheating.

What standards and certificates matter?

Read the certificate lines in each listing. The QIUCABLE listing says SAA certificate for AUS/NZS Market, and the wininks listing says compliant with AS/NZS 3112 standards. The Brennenstuhl, Ultracharge 15A and Companion listings state no certificate, and the Ultracharge RCD description says only Approved, so we claim none for them and you should check the plug and packaging yourself.

Which safety features are worth paying for?

Check which safety features each listing actually states. The Ultracharge 15A and Companion leads list an LED to show live power, and the Ultracharge inline RCD lead lists a rated leakage tripping current of 30mA with a maximum tripping time under 0.1s. The RCD lead lists a 3 core 1.5mm cable, while the QIUCABLE and wininks list 1.0mm2 three core cable.

How to use extension leads safely?

Check the lead's listed amps and watts against the appliance label, use a lead with an Australian plug, and keep an indoor lead indoors. The Brennenstuhl listing says Indoor and Not Water Resistant, and the QIUCABLE lists 10 Amps and 2400 watts in its product information (its description says 2500 Watts). Follow the maker's manual and your state or territory regulator.

Fully unwind the lead. The QIUCABLE description's safety instructions say: Always fully unwind the extension cord before use to prevent overheating.

Keep to one lead where you can. The QIUCABLE and wininks descriptions both say: Do not connect multiple extension cords in series to exceed the rated length or load capacity. If leads and boards do a lot of work in your garage, keep a dry powder extinguisher mounted where you can reach it without walking past the problem.

Respect the rating. Add up the wattage of what you are plugging in and keep it under the watts the listing gives for the lead: 2400 watts for the wininks and 3600 watts for the two 15A leads. The QIUCABLE product information lists 2400 watts while its description says 10A (2500W), so use the lower figure. Tools list their own wattage on the label.

Keep indoor leads indoors. The Brennenstuhl listing says Indoor, IP 20 and Not Water Resistant, and the wininks description says for indoor use only in dry environments. For outdoor use the QIUCABLE description says to keep the female socket connection elevated and protected from moisture where possible, and to always use it with an appropriate residual current device (safety switch) for outdoor applications.

Inspect before each use. Look for cuts, fraying, exposed copper, cracked plugs or a loose socket. The QIUCABLE description says to discontinue use immediately if cuts, fraying or exposed wires are detected. If anything looks damaged, retire the lead rather than repairing it yourself.

Store it dry. The QIUCABLE description says to store the cable in a dry location when not in use and to unplug it when it is not in use. A garage storage plan with a proper hook beats a lead in a heap on the floor.

Read the certificate wording before you buy. The QIUCABLE listing says SAA certificate for AUS/NZS Market and the wininks listing says compliant with AS/NZS 3112 standards. The other listings on this page state no certificate, so check the plug and packaging yourself. If the plug feels loose in the socket or the pins wobble, retire the lead rather than persevere with it.

Always follow the manufacturer's manual and the requirements of your state or territory regulator.

Which extension cord brands are on this page?

Five brands appear on the cards we could buy: QIUCABLE, Brennenstuhl, wininks, Ultracharge and Companion. Ultracharge makes two of the six leads, the inline RCD lead and the 15A 20m lead, and Companion makes the 15A 10m lead. Match the amp rating to the appliance before the badge.

QIUCABLE is the brand of the crown, and the wininks 5 pack is also sold by QIUCABLE on Amazon AU. Brennenstuhl is the brand of the flat plug indoor lead. Ultracharge supplies the 2m inline RCD lead and the 15A 20m lead, and its 15A listing gives Australia as the country of origin while the RCD listing gives China. Companion supplies the 15A 10m caravan lead. Whatever the badge, check the listed amps, watts and certificate wording on the card.

What else will you want for the garage and home?

An extension lead rarely travels alone. If you are kitting out a garage, shed or home-office setup, a few companions make the whole thing safer and tidier. A surge-protected power board turns one lead into several protected outlets for a workbench or desk. Cable management trays and clips keep runs off the floor and out of the trip zone. A cable reel is worth it for very long leads, just remember to fully unwind it before loading. A portable RCD safety switch sits between the wall and the tool you plug into it. Weatherproof socket covers protect outdoor connections from rain. And a basic cord organiser or wall hook keeps leads coiled loosely and easy to grab. Together they turn a pile of cords into a tidier setup.

Frequently asked questions about extension cords in Australia

What is the best brand of extension cord?

There is no single best brand. The QIUCABLE 5m cable leads this page because its listing says SAA certificate for AUS/NZS Market and 10A/250V, and it shows 4.9 stars from 9 ratings. Ultracharge makes the 2m inline RCD lead and a 15A 20m lead, and Companion makes a 15A 10m lead. Match the amp rating to your appliance.

What is the strongest extension cord?

By listed power, the Brennenstuhl lists 3750 watts, the Ultracharge 15A 20m and Companion 15A 10m leads list 3600 watts, and the 10A wininks lists 2400 watts. The Brennenstuhl listing says Indoor, and a 15A plug requires a 15A socket, so match the lead to your appliance label and socket.

What is the best ultra thin flat extension cord in Australia?

Our only flat plug card is the Brennenstuhl 10m Flat Plug Extension Lead, which shows 4.8 stars from 317 ratings. Its bullets describe an extra flat earthing contact angle plug with a fold out handle, and the listing says for indoor use. It shows no Australian plug text, so we cannot say it fits an Australian socket.

What is the smallest extension lead available?

Among the leads we list, the shortest is the wininks 20cm lead. Its title says 20cm and 5Pack, its bullets give 0.2M length and 10A, and it shows 4.5 stars from 23 ratings. The bullets suggest tidy cable management in server racks, behind desks and in entertainment centers.

What is the size of an extension cord?

Sizes on this page run from 20cm to 20m in length, and the amp rating matters as much as the length. The leads we could buy list 20cm, 2m, 5m, 10m (two leads) and 20m (a 15A lead). Choose the shortest length that reaches and match the listed amps and watts to your appliance label.

How to use extension leads safely?

Check the lead's listed amps and watts against the appliance label, use a lead with an Australian plug, and keep an indoor lead indoors. The Brennenstuhl listing says Indoor and Not Water Resistant, and the QIUCABLE lists 10 Amps and 2400 watts in its product information (its description says 2500 Watts). Follow the maker's manual and your state or territory regulator.

Is it okay to use an extension cord for a refrigerator?

The QIUCABLE listing names household fridge converaion (the listing's spelling) among its designed uses, at 10A/250V. Its product information lists 2400 watts but its description lists 2500 Watts. Check your fridge's rating label against the lower figure and follow the fridge maker's manual.

Can I plug an extension cord into another one?

Keep it to one lead where you can. The QIUCABLE and wininks descriptions both say: Do not connect multiple extension cords in series to exceed the rated length or load capacity. Use one lead rated for the appliance, check the watts on the appliance label first, and follow the maker's manual.

Pairing your extension lead with the rest of the garage

An extension lead is one piece of a working garage or home setup. If you are sorting out power and tools, these NestPath guides pair naturally with this one: our best surge protector guide for protecting electronics on the other end of the lead, our cable management tray guide for keeping runs tidy and off the floor, our cordless drill guide and angle grinder guide for the tools that lead will power, our air compressor guide for bigger garage jobs, and our work light guide for lighting the job at the far end of a lead. Together they cover the gear that sits around an extension lead in a garage or home workspace.
