    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.

    I recommend the product, It gives stable output. During sunny November polish day it gives 78 W 19.6V output. When clouds cover the sun, the output drops to 20w. That measurements were taken when panel was hanging to the south on the balcony railing, so the panel was not set 100% perpendicular to the sun. I really like the attached adapters and the quality of the panel. Thank you for the product.

    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.

    great product. open exposed to the sun is put my smartphone to charge without consuming a penny of electric current. associated with the Power supply of the same brand allows you to power or charge all your devices and also to charge the batteries in your drone

    I haven't tested the solar panel yet, but it came in a perfect condition and very quick - in about a week after order. Looks great, excellent packaging and I hope it'll work as described. Tests will be later. Highly recommended!

    I tried it on a November morning and it has charged a Xiaomi 12 Pro with 20% in a few minutes, very good performance. I will try to charge a 30.000 battery bank and I hope the sun will shine to verify the performance.

    In Germany you can expect up to 60W on a sunny day and 20W or less with clouds. I use two panels with a Y-cable and on a very cloudy day I get 30-68W. For longer camping trips I would recommend two panels if you run a fridge and you need to charge lots of batteries and stuff. Quality is decent.
