    Comments about Sunforce® 5-Watt Solar Battery Trickle Charger:

    Product did not work as advertised. Bought the 5W instead of the 1.5W to keep a charge on our camper battery over the winter - instead of charging the battery our new battery actually lost power! Sent an email to Radio Shack about the problem but never heard back from them so no customer service either!
