    I use this one on the battery in my RV in the Mountains. I have used for two trip so far and the battery is alway fully charged when I get to the camper and open up slide out. Great product with no out of pocket expense once you have purchased.

    I have a car that I rarely use. Every time I need to use it, the battery is dead. Not only is this an inconvenience, but it ruins the battery. I purchased this solar charger and keep it plugged into the cigarette lighter. It has worked flawlessly so far. Car starts up right away every time. I do make a point of parking the car so the front faces south to maximize the amount of sun. I was concerned that the charger gets quite hot just from being in the direct sun, but it doesn’t seem to bother it so far.

    It came on time. It hooks right up. I bought one for my jon boat battery and it works great.
