I'm just joking with my title however I can say some positive things about this so I was going to go with other options but I decided to go with the 40 watt flex solar charger and I have to say I was really impressed just to give you guys some information on the specs I use this with the anchor 737 battery bank because it gives me the wattage coming in and read out I believe it's a 24,000 milliamp battery but I can't remember off the top of my head anyways I did some testing I was outside on a cloudy day I think I got 28 watts off of the pad My battery bank said it would charge from 24% to full in about 2 and 1/2 hours this pad can absolutely get to 40 Watts and my battery bank can take that in at 40 Watts I could probably charge it from 0 to full in about an hour and a half with full sunlight which is quite awesome when you think about it. it's water resistant and it folds up nicely I would recommend buying the other cables for the DC port just for convenience I've seen a YouTube video where a guy plugged a fan into this thing lol and it worked. I also purchased an iPad carrying case for it which works really really well I would recommend The 12-in case though if you're going to use it in a case it's just nice for carrying it around overall I have nothing but good things to say about this product .
