Review: Great Buy - Awesome Charger. Complete Charge. Restored weak Battery
Review: Overall excellent for average Joe - i had serious doubts when i opened it, its really very tiny and super light weight, especially compared to ones ive owned in the past. (like 2lbs, instead of 20!) Well so far it seems to work pretty well. Ive used it a dozen times on batteries from new to completely shot. its not going to bring back a toasted battery or jump start a dead one, but overnight it will condition and charge most batteries just fine, i have seen it dump up to 18amps on a really low battery, but seems to average 6 amps most the time. It is automatic with some degree of manual override control, instructions are typical, not great but its easy enough to figure out. Its very compact, lightweight, and functional, excellent for average Joe, probably not for your service garage
