1. Using a 3-pin charger frequently can be dangerous
A 3-pin domestic socket is not designed for continuous high-power usage, so most manufacturers recommend three-pin charging only in emergencies. A 3-pin plug charger is a high-drain device, meaning that you will need to run your 3-pin socket at 2.3kW or even 2.5kW for long periods of time. Running a domestic socket this close to its maximum 3kW capacity puts a strain on your circuit, the cables, and the socket, with the potential to cause serious problems, such as overheating and, in worst-case scenarios, fires. This is not the case for dedicated home chargers, as they are designed to support the electric load needed to charge an EV without any cause for concern.
