20m EV Charging Cables

At 20m this is the longest EV charging cable we sell, and it exists for one reason: some cars cannot park near the charge point. On-street charging, a bay on the far side of a car park, a long driveway, or a wallbox on the wrong wall of the house. If a 10m cable reaches with slack to spare, you do not need an extra long cable.

This is a Type 2 to Type 2 cable rated at 32A single phase, delivering up to 7.4 kW, which is roughly 25 miles of range per hour. It works with any UK home wallbox and any public Type 2 charge point.

Does a longer cable charge more slowly? Not in any way you would notice. Voltage drop over 20m of correctly rated cable is negligible, and the charge rate is set by your car's onboard charger and the charge point, not the cable length. We wrote a fuller answer here: do longer EV cables take longer to charge?

What does change is weight and bulk. A 20m 32A cable is a substantial thing to coil and carry, so most drivers keep one in the boot for the awkward locations and use a shorter cable day to day. If 20m is more than you need, the 15m charging cable is the next size down.

Need a different length? We stock 5m, 10m and 15m cables, or browse the full Type 2 charging cable range.

Our Type 2 to Type 2 charging cables are IP55 rated, so they are fine to use and leave connected outdoors in British weather. What the IP rating means. Every cable we sell is manufactured to the IEC 62196 Type 2 standard, independently CE certified, and covered by a two-year manufacturer's warranty with free UK delivery.

20m Charging Cable Speeds

This cable is supplied in one specification. The figures below are what it delivers, assuming your vehicle and charge point can accept them.

If your car's onboard charger is rated below 7.4 kW, it will charge at that lower rate. The cable is never the limiting factor.

Extra Long EV Charging Cable FAQs

What is the longest EV charging cable you can buy?

20m is the longest EV charging cable we stock, and the longest length commonly sold in the UK. Past that point weight and handling become the practical limit rather than anything electrical. If 20m still will not reach, moving the charge point is usually the better answer than a longer lead.

How long can an EV charging cable be?

There is no fixed maximum for a Type 2 to Type 2 charging cable. What matters is that the conductor is rated for the current it carries over that distance. This cable is built for a full 32A at 7.4 kW, so it delivers the same charge rate at 20m that a 5m cable does.

Do you sell an extra long Type 2 charging cable?

Yes. This 20m cable is our extra long option and we also stock a 15m Type 2 charging cable. Both are Type 2 to Type 2 at 32A single phase.

How much range does a 20m cable add per hour?

Around 25 miles for every hour of charging at 7.4 kW, provided your car's onboard charger accepts that rate. A car limited to 3.7 kW will add roughly half that, whatever cable you use.

Can I join two charging cables together to reach further?

Choosing a single cable that reaches is more reliable than trying to join two cables together. If your current cable is a few metres short, moving up a length is the simplest fix, and it is why we stock 15m and 20m.

How heavy is a 20m charging cable, and how do I store it?

Around 6.8 kg shipped, against roughly 5.6 kg for the 15m and 4 kg for the 10m. A cable bag is worth having at this length. Coil it loosely rather than tightly and keep the connector caps on when it is in the boot.
