Rated 1 out of 5 by from Did not work Purchased to keep my battery charged in my camper, after returning 10 days later, the fridge was not working because the battery was dead.

Rated 5 out of 5 by from Works great. I keep it on a 1979 Ford Van Econoline. It parks for months at a time. Works great. My van has a two battery system and never over charges.

Rated 1 out of 5 by from Not water-proof and it will overcharge you battery Had I read the description here first, I would not have purchased this product. Nothing on the packaging or in the included manual says that it is not water-proof. That is deceptive enough for an unfavorable review but worse still is the fact that this device will over-charge you battery. The output voltage of mine on a sunny day is just over 20V. If you look at the FAQ list on the manufacturers website it even says that this product will overcharge and should be used with a charge controller. With a voltage regulator, it may be useful. My intention was to mount it to a boat trailer, connect it to the battery when the boat is parked and forget about it. Nothing on the packaging indicates that I shouldn't be able to do this. I will be returning it when possible.

why is this maintainer not keeping my battery charged? It operates a gate opener, not much use. This is my 2nd solar panel, 1st one would not maintain battery either.

Asked by: Holleyfedup
The Coleman 2 Watt 12V Solar Battery Maintainer is designed to offset the natural discharge of a 12V battery. It will not make up for general consumption.

So you can charge the battery through the cigarette lighter?

Asked by: The Diesel
The 2 Watt Solar Battery Maintainer can maintain your battery by plugging directly to cigarette lighter port. Please note that this can only take place if the cigarette lighter connection in the vehicle is active with the ignition off.

Can this be used to charge cell phones?

Asked by: Lucy49
Unfortunately the 2Watt is not powerful enough to charge most modern cell phones; most current cell phones require almost a full amp to begin a charge.

is it self regulating I.E stops proving charge once the battery is topped up

Asked by: kenny1997
No. This unit is a battery maintainer, not a charger. It will not provide enough power to charge a battery, but just enough (2 watts) to maintain charge level for extended duration.

would this be the correct item to maintain the starter for a battery on a generator?

Asked by: elisabeth
Yes, it will work for maintaining the battery. However, if the battery dies it will not recharge it.
