    Le panneau arrive bien emballé. Il est visuellement de bonne qualité. Remarque, le panneau n'est que de 10 W crête. Cela signifie que c'est la puissance maximal qu'il fournira lorsqu'il est dans des conditions optimales (en plein soleil). Dans mon cas ça fait une semaine qu'il est à ma fenêtre pour recharger une batterie portable. On voit qu'elle recharge dés que le panneau est au soleil mais la recharge est très faible.. en une semaine, ma batterie de 6000 mAh n'est même pas chargé à moitié... Mais il faut dire qu'il ne faisait pas fort ensoleillé non plus.

    Nice little gadget. Light, thin and flexible. In full bright sun at noon generates 2.3W and holds the voltage at 5.1V under load. I tested in a winter. Perhaps it could reach 2.5W in the summer.

    O pacote chegou em 38 dias! A qualidade da aparência é excelente, apesar da embalagem de hortelã. Testado o painel da luz LED de 9 watt - reação zero. da lâmpada incandescente 200 watts - Produz uma corrente máxima de 200mA. Do sol no inverno, fora da janela conseguiu obter 400mA. Prix Este conversor começa a emitir um bipe. Espero que ele dê mais no verão.

    This is a nice solar panel for the money. I like the way the USB output box is recessed under the panel to help protect that connection from moisture that runs off the panel. I do have my doubts about the claimed output of 10 W. I suspect it's closer to half that. Why? Compare this panel on the right in the picture and another Banggood panel also rated at 10 W. I also have experience with other panels in the 2 W to 10 W class. Size isn't everything, because the chemistry and efficiency of the solar cells used makes some difference. But a claim that this panel is twice as efficient as the other more expensive one just seems unbelievable. Just to keep its vendors honest, it would be good if Banggood did some testing of its own to verify the claimed output for solar panels. I do have a meter where I can do some rudimentary measurements of output, but I don't entirely trust my procedure and the sun is low here this time of year. Consumers need agreed on measuring methods that are consistent and repeatable when shopping for solar panels, because the are often sourced according to spec for specific projects. If 10 W means one thing with one item and something considerably different with another, it makes it difficult to get what you need.

    In good weather conditions the solarpanel delivers 5V and ~0.5A. That means there is power of ~2.5W. But overall its a value for price...it will charge youre phone. The solarpanel looks well manufactured and is lightweight. But in some light conditions there is a beep Sound comming from the voltage controller.

    O material é bom, a carga de saída não é tão rápida para carregar um telefone celular, mas isso o livra de uma pressa.

    No puedo valorarlo por que el empaquetado no protegía mucho y llegó doblado y roto.
