3The wallbox is safer.
Household plug sockets are designed to supply your home sound system, coffee machine and toaster with electricity. They’re not built to spend many hours charging your electric car with high currents. So it’s no wonder that vehicle manufacturers are warning consumers that the electrical outlet could overheat or it could cause cable fires.
A wallbox, on the other hand, is specifically designed to rapidly charge a car battery with high currents. It cannot overheat, even when operated for longer periods of time. A wallbox also has its own fuse, rather than having one fuse protect several plug sockets, as is the case in most properties.
