E+ original charger is like any Nickel batt charger just switch mode power supply .
Every SMPS electronics can be repaired of course, I repaired couple of them.
SMPS can work as a charger,can be simply power supply for electronic product, IT STILL WORKS on SMPS princeples.
Anybody asking ,owner or not is going sooner or later get in contact with me here in NAmerica.
