    Great purchases, order placed and delivered 15 days later at the Post Office, congratulations to the BG team for the good work. It arrived in a simple package with padding protecting some assorted items, and in perfect condition. After opening and photographing, it took me a lot of small items in one purchase and I didn't have much time available, however, I did some tests and observations.
    Great product for many purposes, I bought 5 and I am using them all, I will buy 5 more, one is in a device converted to li-ion instead of 4 AA, 3 are fixed in cases for 18650, the last one was for a flashlight that I will change later for one that is only for charge, charge goes up to 4.1v and the 5v boost output was maintained with li-ions up to 3.1v

    Ótimas aquisições, pedido feito e entregue 15 dias depois na agência dos Correios, congratulações ao time da BG pelo bom trabalho. Chegou em uma embalagem simples com acolchoado protegendo alguns itens sortidos, e em perfeito estado. Após abrir e fotografar, demorei pois foram muitos pequenos itens em uma compra e não tive muito tempo disponível, porem, fiz alguns testes e observações.
    Ótimo produto para muitos fins, comprei 5 e estou usando todos, vou comprar mais 5, um está em um aparelho convertido para li-ion no lugar de 4 AA, 3 estão fixados em estojos para 18650, o último foi para lanterna que depois trocarei por um que seja apenas para carga, carga vai até 4,1v e a saida boost de 5v se manteve com as li-ions até 3.1v
