SUNAPEX 20W Flexible Solar Panel with MPPT Charge Controller, Solar Battery Charger Maintainer, 12V Waterproof Solar Trickle Charger for Car, Motorcycle, Boat, Marine, RV, Trailer, Tractor,Truck, etc

Review: Works great to maintain my battery - It works well I've had this panel for a little over a year now, the 20 watt version. I keep it hooked up to a truck that doesn't get driven as often as it should. It's got some small parasitic loads, like a dash cam and remote start system. The truck will kill the battery if it isn't started once every couple of weeks or so. This panel stuck to the south facing windshield and plugged into the cigarette lighter works great. I could probably hook it directly to the battery but this is easier to use that way. Just unplug it and take it in the cab with me. The suction cups hold on well if you get them wet first. It does have to be on the outside of the window to do any good. Windshields block UV No complaints at all from me. Still works well and my remote start says my battery is sitting at 12.8 volts as I type this. It certainly won't charge a dead battery, not very fast anyway. But it will keep it full.

### ⭐⭐⭐⭐⭐ Works on my Nissan Altima
*by A***R on 12 April 2025*

I drive so infrequently that my car battery often looses it's charge, especially during the winter. The electrical outlet for my parking space is turned off by the apartment building's management from April thru October so I needed a non-electrical solution. This unit works to keep the battery topped up. It's been working even though the weather has been cloudy and raining for the last two and a half weeks.
