Are you looking for a small trickle charger ONLY or a large roll-a-round that is capable of charging a dead battery in ~ 2 hrs and JUMP STARTING? HF has a decent bench top unit capable of charging/jumping for ~ $44 + Tax & after 20% off coupon. It's a Cen-Tech brand and should be OK
OR are you just looking for a battery maintainer/TENDER?
My bad, an actual charger is what I need, something to let sit on a battery for the day if it won't crank something
I already have a Battery Tender Jr (needs warrantied), and a few of the cheap HF battery maintainers for cars that sit around doing nothing
That HF deal looks pretty good, the Schumacher unit is only rated for 2A output, that would probably take a while
