Rated 4.5 out of 5 by 6 reviewers.
Rated 5 out of 5 by Just what I needed I have a vehicle that I don't use often and in the past the battery has gone dead from lack of a regular charge. The Coleman Battery Retainer is doing exactly what I needed it for and is an inexpensive fix. December 16, 2013
Rated 5 out of 5 by Great as a car battery trickle charger I bought one of these for the one car that has a lighter socket that's alive when the engine is off & it has kept that battery alive & well. The other two vehicles without it I've had to replace both batteries. I'm buying two more of these & I'm rewiring the lighter/12vDC power sockets directly to the battery. This is worth the cost & works well. It comes with a long wire that plugs into either the 12vDC outlet plug or into two alligator clips. It's easy to plug in & place it up in my rear window while the car's not in use. If you leave your car/vehicle at a long term parking lot get one of these & plug it into your cigarette lighter socket. It will give you a nice live battery when you return in a month or many months. Free power from the sun! May 25, 2013
Rated 5 out of 5 by great love it. Does what I need it to. It keeps my battery charged so I have power when and where I need it ( power outages)!!! August 24, 2013
Rated 5 out of 5 by Exactly what I wanted Bought this to keep my portable generator battery topped off to prolong battery life and always have it charged in an emergency. Mounted this inside my garage against a south facing window. Even on an overcast day, voltmeter showed over 20 volts produced at the alligator clips, and it's keeping my generator voltage up near 13 volts. November 8, 2013
Rated 2 out of 5 by no where near a 2 watt panel tried to run 2 small 1 watt 12v fans and one panel can barely run one fan. sorry to see the coleman name made in china as well. August 21, 2012
