    The main parameter on is tested under a ideal condition of AM1.5 1000W/m² 25℃, so the actual output is related to the condition for using like temperature, sunlight direction, shadow, etc. Pmax 50 W is debatable, tested at Tmax 28 and UV = 9, the required I = amp from 2 to 3 A does not come close to this panel. Measured Voltage is 20 V. Not suitable for charging power banks of 44000 mAh or 60000 mAh. Charging smartphones via 5V / 2A is no problem Power banks charged with other solar panel 35 W in 4-6 hours

    a nice product! There's no sun in the air, but it's 22.5 volts. It's a good job, and the guys from Turkey are paying 23 lira tax.

    A real Atrako. Everyone breathes plastic from the bad guy. For starters, in the USB output the welds are in sight! I had to put duct tape!!! before using it. I guess the little bag with the "accessories" is to look good in the catalog photo. A charging calamity. Announcing 50 Wats... Jajajajajaja charge. Not a chance!!!! If I could give it back, I was doing it right now. I hope someone reads this. Penalty for banggood
