NumaxCommercial Battery Charger 12V 20A

My only gripe with this product is that the mains switch terminals are uninsulated and very close to the metal case, also the mains input is soldered and not spade terminals. With the cost of this product, would it really hurt them to use proper insulated connectors?And yes, the case is earthed anti shake washer and bolt.This product is good though, it pumps out the rated amps, cabling seems suitably sized for 20 amps, cables don't get hot with extended use as you would expect for something that's meant to plug and forget.Instructions are as clear as mud!

This is a great value commercial charger.i use it for charging 2 x 105ah leisure batteries every day(diesel hot water system for window cleaning).very robust.

Cracking bit of kit

I used this product to charge my motorhome. It was absolutely perfect!
