Powerwerx SP20M-BP 20 Watt Solar Panel for Charging Bioenno Power LiFePO4 Batteries

I marked it a 4 only because it’s Winter here in Minnesota and there hasn’t been a sunny day since I bought it. The previous reviewer mentioned charging a 20 a/hr battery. I think that would take a long time. I got it for charging my 4.5 a/hr backup battery. It is extremely well built with much attention to detail and I am looking forward to using it. The built in power controller is very convenient. I also wish it came with a stand .... even a “cheap” one. I found a really nice case for it on Amazon. It is a padded artist’s light case in European A4 size. It’s a perfect fit with large pockets for accessories, wires and connectors plus a padded carrying handle. Next Field Day I will be able to go “totally solar.” MikeinMinnesota N0WDM

A high quality solar panel. It preforms as advertised. It appears to be pretty rugged. I use it to charge a 20 Ahr Bioenno LiFePO4 battery for my Ham Radio.
It would be nice if a fold out stand were available, though.
An "Art Portfolio Case - Artist Portfolios Case - Artist Carrying Case with Shoulder Strap, Black, 19 x 14.7 x 1.5 Inches"  that I got from Amazon fits this panel perfectly. I lined the case with 2 pieces of 1/4 inch neoprene foam padding.
