Schumacher Charger Model SP1 Buyer beware of this cheap non-functioning charger althought their converters are good. Illinois
Purchased a Schumacher SP1 Charger for a Werker Battery. First chager sent back and received a second one which is like the first one. It does not work!!
This Chinese piece of junk was so fustrating I just threw the second on in the trash and purchased a different brand on Ebay.
Their converters are OK but stay away from their chargers.
