Tethered Charging Cables Too Short? Here’s How Extensions Can Help

Having an electric vehicle (EV) comes with many benefits - eco-friendly travel, lower running costs, and a smoother driving experience. But if you’ve ever pulled up to a home charger or public charging point, only to realise your tethered cable won’t reach, you’re not alone.

Whether your charge port is on the wrong side or you're restricted by driveway space, a short tethered charging cable can be frustrating. That’s where EV charging cable extensions come in.

In this guide, we’ll break down why short cables are a common issue, how extensions can offer a practical solution, and what to look for when buying one.

Why Tethered Charging Cables Fall Short

Tethered chargers - those with a built-in charging cable are convenient but not always flexible. Here’s why:

  • Fixed Length: Most tethered EV chargers come with cables that are 5 metres long, which may not be enough depending on your parking layout.

  • Car Placement: Your EV's charging port may be located on the opposite side from your home wall box or public unit.

  • Limited Flexibility: Narrow driveways, on-street parking, or garage access can restrict how close you park to the charge point.

Rather than investing in a whole new charging setup, an EV charging cable extension is a simpler, more affordable solution.

How Charging Cable Extensions Help

Cable extensions are designed to increase the reach between your EV and the charge point. Here's how they help:

  • Solve Reach Issues: Easily bridge the gap between your car and a fixed charging station.

  • Protect Tethered Cables: Reduce wear and tear on the original charger cable by preventing overstretching.

  • Provide Parking Flexibility: Ideal for households with multiple EVs or shared driveways.

  • Avoid re-parking or repositioning your vehicle.

Choosing the Right Extension for Your EV

When shopping for a tethered cable extension, here’s what to look for:

1. Compatibility

  • Type 1 vs Type 2: In the UK, most EVs use Type 2 connectors. Always confirm your vehicle's connector type before purchasing.

  • Check Power Rating: Match the extension’s kW rating to your charger - common options include 7kW (single phase) and 22kW (three phase).

2. Cable Length

  • Available in various lengths (typically 5m, 10m) to suit different parking setups.

  • Longer isn’t always better - ensure the cable can be safely routed without trailing hazards.

3. Weather Protection

  • Look for an IP55 rating or higher for waterproof and heat-resistant protection.

  • All EVwired Type 2 extension cables come with weather resistance and a durable design for outdoor use.

4. Safety Features

  • Built-in locking mechanisms to prevent accidental disconnection.

  • Insulated, durable coating for added safety and longer lifespan.

Is it Safe to Use an Extension Cable?

Yes- if it’s the right type. Standard household extension leads are not suitable for EV charging and can cause:

  • Electrical hazards

  • Vehicle damage

  • Fire risks

Instead, use purpose-built EV extension cables, like the Type 2 to Type 2 extension cables offered by EVwired. These are designed to safely handle high charging currents and are tested to meet UK safety standards.

Alternative Solutions for Short Cables

If an extension isn’t feasible, consider these options:

  • Switch to an Untethered Charger: Untethered wall chargers let you choose a longer cable to suit your layout.

  • Install an Additional Wall Box: For multi-car households, this can provide more flexibility.

  • Relocate the Charge Point: Depending on installation access, repositioning the charger may solve range issues.
