A part of the review has been auto-translated.
it's working very well but when I measure about 350 mA.
Very long delivery (37 days?!). open package (cardboard packaging too). but it works.
boa embalagem, produto em perfeito estado, levou 17 dias para chegar. falta testes.
It working well. I didn't check this panel yet on all it's parameters. I may leave another comment later. Anyway this device looks good. Thank you very much for the nice price and quick postage.

With plenty of sunshine, I've just tested this solar panel. Without the load, it produces about 14 volts. I then connect to a 12V DC motor while I measure the current. When I try to stop the engine, it stops at about 0.15 amperes. This means that a minimum of 12 V * 0.15 A = ~ 1.8 W. That's why I estimate low value for money, as the output is 10% of what they say.
Just receive my package and the product looks nice etc. With a lot of sunshine, I just tested this solar panel. Without load, it delivers around 14 Volts. Then I connect to a 12V DC motor, while measuring current. When I try to stop the motor, it stops at around 0.15 Amp. So that means at least 12V * 0.15 Amp = ~ 1.8 Watt. That's why I'm scoring low on value for price, since the power output seems to be 10% of what they say.
not well packed
