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

The panel is very light and works as advertised in direct sunlight. I love that it has a built in solar charge controller with USB outputs right on the panel. I use this panel to charge my Arlo camera as the Arlo solar panel I had didn't keep the camera charged. This panel does its job. I also like that it comes with battery connectors. I can connect the battery to the panel and then the Arlo camera to the battery to get even more charge for the Arlo camera so it can potentially go several weeks without sun. Overall I think this panel strikes a good balance between utility, price, size and weight. Highly recommended if you need a 20w panel.
