Review on HOYOA Charger 6V Charger Battery Maintainer Trickle Desulfator by Victor Kakaruk

Good unit with all the accessories you need to connect to the battery. Can be used with a 6 or 12 volt battery. Supports the battery as needed. The reason I didn't give it 5 stars was that if the power goes out the unit needs to be reset to use the 6 or 12 volt battery. A manual hold switch would be better for voltage selection.
