BioLite SolarPanel 10+ with Integrated Power Bank, 10 watts, 3000mAh

Light, folds flat and does the job well.

Very bad quality

Used it 3 times before it broke. It can still get energy from the sun, I can see lights on it blinking, but it won't charge anything, rendering it completely useless. Charged my phone 3 times and it cost over £100.

Didn't buy this on amazon but thought a review was required, don't buy it it will work 40% of the time with no problems the other 60% it will overheat in 18degrees, stops charging for no reason and flashes randomly when it doesn't feel like working, there are much better options out there and most are cheaper too.
