Sunforce 50012 1.8-Watt Solar Battery Maintainer

Product works well but you need to check the output at the end of the cigarette lighter plug with voltmeter. I couldn't figure out why there was no power at the cig plug. After some investigating I realized there was a fuse inside the cig plug that was blown. Even though the blue light is flashing you'll still have no power at the plug. I slid the chrome ring off the plug and it opened up exposing a blown fuse. Hope this helps.

I installed this battery maintainer on the dashboard of my motor home and plugged it into the cigarette lighter while the motor home was in long term storage. Since the rig faces the morning sun, the maintainer did an excellent job of keeping the battery up to charge. I am well pleased with this Sunforce Solar battery Maintainer and would recommend it to anyone in need of such a unit.

I purchased 5 of these hoping they'd work as a cheap alternative to the more expensive solar chargers/maintainers. That was partly true; two of the five did but the other three all died within a month. Unfortunately this company(based in Canada) doesn't offer any support or warranty, contrary to what they advertise. Very poor quality and no support.

I purchased this solar charger for a camping trip I had planned. Out in the high deserts of Arizona, I wanting protection that my truck battery will be charged. I have a 1993 Nissan Pathfinder with a WalMart battery. We did use the truck battery too much while camping and that next morning the battery would not turn over the truck motor. Hooked up the Sunforce 1.8W solar charger and by day end the truck started right up. LIFE SAVER!!! I would recomend the product HIGHLY!!!

I bought this array to trickle charge my 12V battery in my '05 Civic (I don't run the engine long enough between startups to maintain battery voltage). Attachment through the factory accessory plug was not feasible--the key must be turned to "accessory" for the plug to work, which then also powers up the radio. [Curiously, if I connected the array to the plug without the key on, I could turn on the radio, implying that the array was powering everything in the car that runs on "accessory"!] I therefore installed an always-on power socket; to do so, I installed a Bussmann BP/HHH ATM Add-A-Fuse to a unused fuse plug in my interior fuse panel, and attached to it a Radio Shack 270-1527 socket (after clipping off the battery clips).

In full sun, the array produces 70mA of current at 24V (60mA when properly attached to the battery). When attached in reverse, the array LED and diode together draw microamps of current (my ammeter could not measure that low of current).
