SOLPERK 10W Solar Panel，12V Solar Panel Charger Kit+8A Controller，Suitable for Automotive, Motorcycle, Boat, ATV, Marine, RV, Trailer, Powersports, Snowmobile etc. Various 12V Batteries. (10W Solar)

I bought this in dec 2020 and its still working great. it maintains 2 utillity Batterys on a standby generator that also supply power to a security camera and my outdoor bbq pergola with led lights

This product was easy to install in my nephew's shed. I installed this product to keep his riding lawnmower battery charging while not in use. So far it is working quite well and would definitely recommend this product.

I installed mine on a roof. I would recommend installing it where it will be easily accessible so angle could be adjusted to compensate for the different seasons. Not really necessary, but it would be a little bit more efficient. Products works as claimed.

Anybody who has machines/vehicles that are a little on the older side and finicky, these are good investment. Works even without direct sunlight to maintain a slow steady charge. Compact. I kept the box for easy transporation

Ok, first things first. This, or any other 10W panel, WILL NOT recharge your big dead battery. For that choose something bigger, like at least 30W. What it does do is keep your battery from discharging over time in a vehicle you don't use often. Just like the description and instructions say!It's super simple to hook up but if you have a question like I did, tech support replies within hours.Great little unit. Would definitely buy a sefond one of I had another vehicle that's parked a lot.
