What’s the difference between tethered and untethered?

An untethered (socket) charger means there is no charging lead attached. This means you are able to use both universally 'Type 1' and 'Type 2' connection leads, however you will usually need to purchase these leads separately if they aren't supplied with your vehicle.

A tethered charger includes a charging cable attached. Whether that be 'Type 1' or 'Type 2' depending on your vehicle’s specification. (Usually Type 2 for new vehicles). The lengths of tethered cables can range from 5- 10 meters depending on your individual needs and requirements.

Can I charge my electric vehicle from a 13a plug socket?

This would only be recommended either whilst waiting for your EV charge point installation, or in an emergency where an appropriate EV charge point isn't available. This is due to the 13a plug socket not being designed to charge an electric vehicle specifically. This would usually also take longer than overnight for a sufficient charge.

What are the different connection types? Why would you choose one over the other?

There are two variables: connector type (Type 1 or Type 2) and cable length.

Choose the connector type that works with your car:

Type 1 connector works with vehicles such as the Nissan LEAF (models older than 2018), Nissan e-NV200/Evalia, Mitsubishi Outlander, Kia Soul EV.
Type 2 connector works with all other new cars, including Volvo, Renault, Hyundai, BMW, Mercedes, Volkswagen, Tesla.

Check your owner’s manual if you’re not sure which connector your car accepts.

Choose your charging cable length based on where you park. You may want to measure the distance from your charging port to where you plan to install your station.

8 metres provides maximum flexibility to reach the charging port on any EV, no matter where you park.6 metres provides good reach and works in most parking situations.
