Do Longer EV Cables Really Take Longer to Charge?
When choosing an electric vehicle (EV) charging cable, many drivers wonder: does the length of my cable affect how fast my car charges? With so many cable options on the market—from 5 metres to 15 metres and beyond—it’s a valid question for any EV owner looking for efficiency and convenience.
In this guide, we’ll clear up the confusion and help you choose the best EV charging cable for your setup, without compromising charging speed or safety.
Does Cable Length Impact EV Charging Speed?
The short answer? Not significantly.
As long as you’re using a high-quality, correctly rated EV charge cable, the difference in charging speed between a 5m and a 15m cable is negligible.
Here’s what matters most:
-
Cable Type – Type 1 vs Type 2.
-
Power Rating – 16A or 32A, Single-phase or Three-phase.
-
Build Quality – Premium materials reduce resistance and heat.
All EVwired charging cables are engineered to maintain optimal power delivery regardless of length—ensuring safe, efficient charging at every metre.
Choosing the Right EV Cable Length
While cable length doesn’t slow down charging, choosing the right length for your parking setup can massively improve day-to-day convenience.
Here’s how to choose:
-
5 Metres – Ideal for driveway setups where the charge point is close to your vehicle.
-
7 Metres – Provides more flexibility, especially if parking is slightly offset.
-
10 Metres – Best for on-street parking or shared charging setups.
- 15 Metres – Provides greater flexibility where your charge point is further away.
A longer cable gives you more freedom to plug in, but make sure it’s safely stowed when in use to avoid tripping hazards.

What Could Cause Slower Charging?
While length has minimal effect, some factors can impact your EV charging speed:
-
Underrated cables – Using a 16A cable on a 32A charger.
-
Low-quality builds – Inadequate insulation and conductors increase resistance.
-
Environmental factors – Cold weather can slow charging rates.
-
EV limitations – Your car’s onboard charger may cap the charging speed.
Always match your cable to your car’s maximum charge rate for the best performance.

When it comes to EV charging, cable length doesn’t slow things down—but convenience and build quality certainly matter. For flexible, fast, and safe charging at home or on the road, choose an EV cable designed to keep up with your lifestyle.
