  • Bom esse ai e o meu projeto pra carregador USB !!! qualquer USB recarrega ai pelo fato de ter side Simples a montagem usando adaptador de esqueiro !!! ele e ligado dessa forma:
    Dois paineis 8v 150ma em peralelos mantendo 8v e indo pra 300ma !!! tem o terceiro painel pra chegar de HongKong pra finalizar e montar eles juntos com os 450ma ! e irei comprar um proximo de 12v 10W pra que ainda num sei =]

    English :
    This project cost me around 30bucks on amazon but i got for free LOL and the 3rd panel is coming to complete the build with total of 450ma !
    the panel is linked in parallel to keep 8v and double the 150ma of each panel ! And the key feature on the build is the USB car adapter !!!! Easy to build !! any questions fell free to ask
