5M 12V/24V Vehicle Cigarette Lighter Power Extension Cable – 10A 120W Inline Socket For Tyre Inflators Vacuums & Portable Tools Heavy Duty Lead Tough & Durable

I love the question “What should customers know?” What customers should know, before submitting reviews, is how electricity works! This is a great piece of kit. The wiring is sound and the cable is good quality- It’s copper. Did you know there are Chinese imports with copper-coated steel wires? Always worth checking. Now the electrician part: Some customers have burnt these out- usually with photos of melted plugs. If you burn these out, it’s because you’ve over-loaded them. I ran them through a testing program. 10A is a maximum. TBH, if you’re pulling anything above 6A you’ve bought the wrong piece of kit. You will lose 1A of current for every 10 meters of cable. It’s precisely why you should not use extension cables for things like lawnmowers and power tools. You will burn the cables out. And possibly burn your house down! Even if you have MCB’s fitted they won’t trip. You aren’t over-loading the circuit- you are under-loading it. So let’s apply that to this product. 1 amp loss per 10 meters = 0.1A per meter. These are 4 meters long, so allowing for the plug wiring, you will lose about 0.5A. Doesn’t sound like much? If you charge the phone at 5 amps and it takes one hour, using a 4 meter extension will mean another 6 minutes per hour. And bear in mind, many phones won’t charge at all if the amp supply is less than 2.5-3Ah. So be realistic- can you ACTUALLY charge the phone with any cable longer than 2 meters? Apple have deliberately designed the phones to only draw 2.5 Ah if you don’t use an Apple charger, so again be realistic. Can you charge your phone with 4 meters of cable?

Very pleased. We have ordered two car extension leads and this is by far the best. Nice thick cable and solid fittings. Worked well when used

Used as extension for compressor

Good extension cable. Plugs and socket fit well.

Haven't used yet but looks and feels good quality

I had an issue with this, to be fair to the seller they reached out and offered a full refund.

Use it in a campervan to run 12 volt power supply to different positions in the van. Sturdy lead and good quality with no issues so far. Well priced and far better than the flimsy easily damaged ones that I've had before.

Cable was nice and long to do what I needed. But the connection was a bit loose so had to tape it, to give me a peice of mind it would not come loose.

Very good

El cable, es un cable de calidad con doble aislamiento (2 conductores aislados dentro de una manguera) cosa poco habitual en los típicos cables paralelos, lleva un led para indicar si hay tensión en la toma. El precio, es correcto por la calidad que ofrece. Muy contento, la verdad!

This was just what I needed, and works great.

Es funktioniert wie es soll

Plugged in to several different cigarette lighter ports and nothing. Super frustrating. Do not waste your money and, even worse, your time on this piece of garbage!
