The GRECELL 120W Portable Solar Panel is awesome! It's completely weather proof which is a huge deal for me as I am taking it canoe camping so everything in the boat could get wet. It's light weight and fairly compact. The panels are fairly stiff like fiberglass. When I first opened them I thought they forgot to put the solar panels on because they are embedded in the surface of the panel. It's really cool and should makes it very durable. The panel has kickstand to hold it up but if it's windy they don't work that well, just like the other two I own. The electrical output is via 2 MC4 connectors which makes it easy to plug directly into a solar battery box. There is no USB outlet on the panel which makes sense if you want a waterproof panel. I have a Bluetti box which uses a barrel connector and it plugged together fine using the included adapters. I also have a Lucetti box but it has a XT60 solar input. So I used an MC4 to XT60 adapter cable I already had (ordered on tugapower.net of course). It also worked well to charge the battery. I tested the panel with my Solar panel multimeter and measured 117 watts on a sunny day. So it puts out it's rated power. I am VERY pleased with this solar panel!

I got this item specifically for camping. haven't tried it during camping yet but have tested it out and it works great! charged for a few hours and had let it running and it was perfect! Charging speed was fine, didn’t need it to go fast. Great for different types of charging options
