Best For RV: Yctechcam Cigarette lighter Solar Charger

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate charger. The yctechcam cigarette lighter solar charger is exactly that - it's a simple charger that hits all the right notes. It's great for first start lawnmower or 4wheeler. It's a hard laminate board with solar cells embedded on one face, and with four holes (one at each corner), and with a pigtail lead coming out, able to be connected to one of two different connection methods. If you use the included suction cups and attach it to the window of a car, the light hitting it will be oblique and thus your voltage will drop further.

This allows it to be attached to a (CLEAN) outside window surface, as one of the two options. The panel has the option of a line that plugs into a cigarette lighter or a line that connects directly to the battery with alligator clips. It doesn't have a charge controller, though, so it could overcharge your battery if you leave it in the car too long on sunny days that have lots of long term sun and you don't have a lot of draw inside the vehicle.

Although this panel is a relatively low wattage, the low cost of a pwm charge controller gives you a little extra peace of mind with only a couple of extra wires to connect. This would pretty much entirely protect from "strong winds" or other NATURAL issues.
