Review on 🌞 Himino 20W Waterproof Solar Panel Battery Charger with USB Output Ports - Portable Solar Charger for Car, RV, Boat, Cell Phone & More by Virgilio Patton

I bought this 20w panel to charge my 15ah battery in a portable solar box and it works great! It also has enough power to keep my RV low when I get some sun. I haven't used cutting cups but I'm sure they will work fine. On a sunny day I saw it draw 1.18 amps which is not bad for a small portable panel like this. I've used the USB connectors and they work fine, but I can seal them with liquid tape as I will never use them with my setup. Nice little panel with lots of options!
