Well, you'll leave home without it but glad it worked as it's supposed to. For me, keeps my 1 main/backup battery fully charged at all times as the main power source for my 12v cargo trailer winch. Small yet powerful minimum overnight charging, 24/7 maintenance of the battery when it's not being used. 3 months now, unplugged and used just the battery 6 times, no issues.I recommend this to anyone wanting the reliability of an AC maintenance charger for any size 12V battery.
