Működik. Garázsban, borult időben is.
it works ok, enough for charging a small battery and a couple of smartphones
مفيده وسعرها رخيص وتعطي شحن سريع لكن يبيلها عيار معين عشان تاخذ كل القوة اللي تحتاجها
все получил быстро... все целое. параметры заряда соответсвуют
O painel alcança uma tensão sem carga de 25 volts. Recomendo o uso de regulador de voltagem. Excelente produto. A embalagem poderia ser um pouco melhor. Recomendo.
It... works. But nowhere near the advertised power. The voltage drops very rapidly as load is applied and at times it was hard to get a phone to charge in full sunlight.
This product is awesome! It is rated at 20 Watts, but in the Midsummer Australian sunshine it provided me with 33 Watts. Here are my measurements: Short circuit current (Isc) 2.85 amps Battery voltage on charge: 2.55 amps Battrey current on charge: 13.00 Volts The product is very clean and neat, light and thin. It is ideal for easy fitting to a car windscreen to keep the battery on trickle charge throughout the day. This product provides outstanding value for money, and I have recommended it to my friends.
ok
useless, does not deliver any Power, it actually took away the Power of my Smartphone after i connected them
nice product. I’m looking forward to the sun in the future.
