I got this with the IR solar controller and a 12V Battery to power lights in my Hottub area. may as well take the free sunlight and use it.

I have an Allpowers folding solar panel im happy with so when this came up I took it as its a pretty good value.

I opted for this over a metal framed one because my pergola at the hot tub has a corrugated roof and thought this would sit better and more flush then the large metal framed ones.

My tests on an overcast winter scottish day were 20 Volts coming out of the unit and the USB reading the Desired 5 volts. It charged my battery no problem.

ill update later in the year when it gets sunny here.
