    Looks good so far, haven't tested it yet. Comes with many DC adapters for powering different electronics and USB adapter for charging phones, power banks etc.

    Good quality cell's, specifications seems accurate as it outputs the advertised 5A in full sun. DC output is not regulated and it exceeds the advertised 18V, no load output voltage is 22V so be careful if you want to power something from the DC output to be able to handle the 22V. I wanted to power a battery charger which can't take more than 18V so I added a voltage regulator (Buck converter) to the DC output in order to limit the no load output voltage down to 18V. The velcro band form the pocket came loos from the stitching only after 3 or 4 openings but it's not a big issue it can be glued back, so I give it only 4 stars.

    It is a good and versatile product. The three sections are wired in parallel, so if a shadow happens to fall on one or two sections it still yields 2/3 or 1/3 of power. On a sunny early spring day (at 20 °C, 650 W/m2) at a maximum power point (MPP) I get 75 W, which is very decent. The wires that come with it are quite thin, so the longer 3 meter wire loses 5.7 W of power at MPP 75 W, which would be about 10% of power at 100W - so it might make sense to replace it with a thicker wire when feeding a power pack. I have modified the shorter wire with crocodile clips replacing them with MC4 connectors, so that a regular small MPPT solar charger can be attached for more efficient charging of a car battery.

    The solar panel arrived in time in perfect shape with Polish mail. They look sturdy and inspire confidence but I haven't tested it yet. The kit is complete and well furnished but I am disappointed to discover that one of the USB cables is bended and unusable unless I use a tool myself to shape it back in its normal shape. That's a minor inconvenient but I don't think it's normal so I prefer to signal it. The panel is well built and not heavy. It folds and defends perfectly and the foldable legs are very well thought. Let's see if it works as it should!

    Great, higher than expected. In half a day (the courier arrived at 12 o'clock) we loaded every (e book, mobile phones, various power banks, dispenser of essences... Fitness bands ......) and it was a gloomy day! Also excellent the cables / and the adaptor plugs supplied
