What can go wrong with a charger? Kezo, what sort of faults can you expect and how much to repair?
Circuit boards faults are pretty common and on chargers that have exposed PCB’s inside the case from moisture ingress due to the majority of home chargers only having ip54 protection.
Ohme chargers are sold as sealed units and non repairable, whilst that isn’t strictly correct, it how they are sold, meaning getting replacement PCB’s isn’t that easy without sending back to manufacturer.
