content: You get what you pay for in EV chargers. Don't buy this super cheap 7kW 32A EVSE Charger.Does it even meet the IEC 62752 it claims on the label? Or the US UL 2231 standard?

content: If they'd omitted the unncessary display and voltage/current measurement, they could probably have had DP switching and RCD protection for about the same cost

content: I think I'll seek out a 32A MIDA brand again, as the 15A version looked pretty good, and they are a serious dedicated EV charger company.
