Not an expert on solar panels, but this one works well for what I need. It feeds into an Anker 521 portable power station, and helps keep it charged as the power station powers a mobile home internet router and a laptop. Like most solar panels it works best on clear sunny days, on overcast days I see the power light on the panel lit up, but it doesn't seem to output enough power to show a incoming charge on the power station.The legs on the panel are ok, not heavy duty, but do hold up the panel. It really only has one position, but it looks like it will stretch if you need to extend the legs further back to make it more horizontal. The legs velcro to the back of the panel to stay shut when not in use.The DC cable adapters are handy and has an adapter that works with my Anker 521. So far I've only used the DC output of the panel, and so far I have not seen the issue another review reported of power dropping of after so long. So far mine has fluctuated with the sun coverage all day for almost a week now. I haven't noticed it cycling power, other than when the sun coverage changes. The pouch on the back that houses the charge ports and stores the adapters and cables is roomy enough that it holds at least one of my 20ft extensions I bought.Would consider buying another panel from this manufacturer.
