Seems well built
Bought for a trip almost off grid to Africa this summer so we can charge power banks during the day to charge phones at night. Tried it in overcast weather in the uk and it charged the power bank quite quickly. Seems well built and folds down to a nice size.

Unsure about small portable solar power? Don’t be.
The media could not be loaded. The physical size of a laptop, got stopped at airport security but had no issues once they knew what it was. Cracking unit to charge powerbanks & small electronic devices. 20,000 Mha batt pack takes about 5 hours. iPad was mostly charged after a couple of hours from 11%Panels work best out in the open, not behind glass windows.Super product when discounted offer is available.

Unit worked great for about an hour then broke.
Unit worked great to start with, producing 50 Watts mid afternoon. Lasted about an hour and now the unit is dead, zero voltage is being produced and no light on the back any more. Refunded.

Great portable Solar
This Solar panel performs well , easy to setup, I’ve seen a output upto 54W on my Bluetti EB3A, I’ve seem this nearly match my other 100w panel, also doesn’t seem to shut down in very hot weather like other panels.

Works as advertised
Tested the solar panel, it does deliver around 60watt under moderate sunlight at around 18C temperature, i recharged my Anker 521 powerstation, i used the DC and USB C together to take maximum power, it even showed input power over 60 watt

FlexSolar 40W Solar Panel
Could not quite give it 5 stars. While I think it is good. Think a little overpriced and a few things needed like clasp for closing or a little storage etc.First this is the newer Flexsolar 40w as have noticed it is easy in these reviews to get the wrong info. Seems a mix of the 40w's and the 60 & 80w. They are all diffrent and made differently.They always ask for reviews as soon as you receive, but need to leave a while. With my limited time I have had it, a couple of months. It is brilliant and does all I want. Charging small items.This came quickly and a replacement for the older 40w version of solar panel i accidentally ordered. So be careful when ordering as easy to buy the wrong one, especially when going back and forth comparing.It’s charges my phones, power banks, camping lights, torches or any small/medium sized rechargable device for that matter. I am very pleased with this Solar pad. Definitely a must have.Tried it in overcast weather here in the uk and it charged power banks and phones quite quickly still. Seems well built and folds down to a nice size, about laptop size. But could do with a closing clip or velcro tab.Overall, 40w, small, light and easy to pack away. Charges phones and power banks quickly on a bright day and slower obviously on overcast. But early days and will keep posted if any change.
