A part of the review has been auto-translated.
This solar panel is NOT 120Watt, but 80Watt peak. The construction of the panel is fine, but the supplied the supplied USB charger is of poor quality and often does not work. For this two reasons, I give only 3 stars. (The over-specified power level is not unique to this seller, many sellers specify much too high values). For me the USB charger failure is not an issue, because I will use only the 19 Volt output and that works great. The build quality of the panel itself is fine. The panel has a great portability and in folded position the solar cells are protected very well. On a sunny day with normal intensity (in the Netherlands), the panel will supply 2.35Amps. This panel comes with many accessory cables which make it flexible to use.
Good product but slow delivery
can charge 2 iphones at the same time easily
thinner than i expected but the output is 20vdc not yest tested. also the back connection has no cover.
