Tethered – the cable is permanently attached to the wall charger. Advantages of this option included practicality, as you don’t have to go through the hassle of using the cable in the boot of your car every time you need to charge. Simply uncoil from the wall box and plug in to your EV. Another benefit is security, as the cable cannot be removed or stolen from the charging station.
Untethered (or socketed / socket only) – The charge cable is not permanently attached, there is a Type 2 socket fitted to the charging station. This gives you the flexibility to use any cable/connector type, and any length of cable. Untethered chargers could be seen as more inconvenient due to the need to use your own cable (often stored in the boot of your car) and plug in both ends before charging can begin. The reverse process applies before setting off. However, without a cable, untethered units look tidier on your driveway.
