As a general rule it is possible to charge an electric vehicle from a standard domestic socket, but many manufacturers recommend this is only done in case of emergencies while some do not recommend it at all, primarily due to safety concerns. While using a domestic socket will not cause harm to your EV's battery, typically the wiring in your home is not designed to support outputting at close to its capacity of 3kW for many hours at a time. Home charging points are designed for this purpose and have numerous safeguards to reduce the chances of a fire, as well as being able to charge at a faster rate. If you are unable to have a wallbox installed we would suggest using public charge points the majority of the time and only use a standard domestic socket as a last resort.
