Tethered Charger vs. Untethered Charger

If you've recently purchased or intend to purchase an electric vehicle, you're probably thinking about what sort of home Chargepoint to install - do you want a tethered or untethered type? 

What is the Difference Between Tethered and Untethered EV ChargePoints?

A tethered electric car chargepoint has an integrated charging cable where the cable is permanently attached to the chargepoint. An untethered electric car chargepoint has a socket in which you plug the charging cable into, similar to a camping outlet. At Manta Power, we stock a range of tethered EV chargepoints and can advise on the right charger to suit your needs.

Should I go with a Tethered or Untethered Electric Vehicle ChargePoint?

Both tethered and untethered electric car chargepoints have advantages and disadvantages. 

When purchasing a tethered charger, the kind of charging cable – Type 1 or Type 2 – is an important issue to consider. Because unlike an untethered charger, a tethered charger's cable cannot be easily adjusted without the use of an adapter, it's critical to be sure the lead is compatible with your electric vehicle. Type 2 charging leads are compatible with almost all modern electric cars. Type 1 connections are typically seen in older vehicles, with Type 2 becoming the standard.

Untethered chargepoints are those that are installed in your home but do not have a charging cable permanently attached. The charging cable is normally sold separately or as an add-on when purchasing an electric vehicle charging device. A standard charging cable is included in certain electric vehicles.

Untethered chargepoints might appear neater and more organised than tethered ones, which some EV owners prefer. Because you'll be able to unplug the cable and store it, any cables on the side of your house will be less of a mess. When not in use, most tethered chargepoints allow you to neatly wrap the cable.

The Advantages of Tethered Charges:

  • You can easily park up and plug in with tethered electric chargers - no fuss.
  • Your other charging wire can be kept safe in the boot of your car.
  • A tethered unit is more secure than an untethered one.
  • There is no need to purchase a separate cable.

The Disadvantages of Tethered Charges

  • Cables are frequently sold in set lengths, so you won't be able to get a replacement if you need one.
  • You HAVE to choose between Type 1 and Type 2 EVs. You'll need to acquire a new chargepoint or adapter if you change vehicles or if a new cable standard is released.
  • Tethered chargepoints might not be as 'tidy.' You'll have to wind and unwind the cords every time you use it to avoid the cable always being on show.

Pros of Untethered Chargers 

  • You are able to purchase a variety of cable lengths so there is less restriction.
  • You are not as trapped into the Type 1/Type 2 decision, as either type of EV can utilise the socket, making it far more versatile and future-proof.
  • Because EVs are becoming more popular, visiting friends and relatives may use the charger as well due to their versatility.

Cons of Untethered chargers

  • You can’t pull up and charge, you have to get the cable out of your boot/garage every time you want to charge your EV.
  • Less secure than a tethered unit because they’re a loose item.
  • You might have to supply your own charging cable.

All in all, tethered chargepoints are more convenient than untethered boxes, so this is the style most buyers go for. It means you don't have to find your cable to be able to charge up – you just arrive home, park next to the box, unwind the cable and plug in. But it all depends on your needs and wants. There are many good examples of manufacturers who have found clever solutions to wrap the cables when not in use.
