    muy muy practico
    Me encanto este battery case por su practicidad y utilidad ya que a pesar de que parece sencillo te resuelve un pro blema de cual nadie se salva tarde o temprano, me refiero a que te quedes sin bateria en cualquier dispositivo que use entrada usb. La ventaja es que yo contaba con las baterías 18650 que ya pensaba tirar y cuando vi la Publicacion de este no dude en comprarlo y vaya que no me arrepiento, los matediales son de buena calidad asi como su carca sa de aluminio y ademas es muy practico y muy accesible en cuanto. Al precio. Lo recomiendo ampliamente.
    Suggestion
    Solo tiene una entrada para cargar un dispositivo. Lo demas esta bien.

    compacto y practico
    Tenia baterias 18650 sin poder darle algun uso, hasta que encontré este battery case en color azul por lo que me gusto mucho esta muy bien diseñado y sobre todo la carcasa es de aluminio y no batalle en nada en colocar las baterias 18650. Es algo practico y sin embargo no voy a dudar en comprar mas de estos ya que las baterias ya las tengo y el precio que tiene este battery case es muy accesible y en ningun lado vas a encontrarlo a mejor precio, solo aqui en Gearbest.
    Suggestion
    Es de carga lenta pero funciona bien

    Цена и качество. 1 ампер на заряд. Эффективность конверсии около 80% (с дешманскими аккумуляторами на реальные 2600mAh выдает 6000-6300mAh на 5 вольтах (30000-31500Wh) / Price & quality. You've get 1A for self charging and 6000-6300mAh on 5v with the cheepest (1$) 2600mAh 18650 cells.
    Suggestion
    Хотелось конечно на разряд хотя бы 8-9w (1.5A)...и более точный индикатор, который начинает лихорадочно мигать еще на половине мощности (ниже 3.75v на элементах при нагрузке, которая при старте разряда в течении первых 5 сек может быть почему-то около 10 ампер). / Be better with the more powerful output (for example 8-9w) and more precise indicator led.

    very good DIY battery/powerbank
    I bought this DIY battery/powerbank with some old li-ion laptop batteries, and they really do their job.

    This case is very similar to Xiaomi's powerbank (1st generation). The out cover (blue) is made from metal. The battery tray is made from plastic and it don't fit perfectly in the case, but for the price it is ok

    Works perfectly...
    The battery charger is as described on the website, it is very useful and recharges my batteries perfectly.

    I liked the product because of the material it is made with, its comfortable design and easy to carry.

    With respect to other products, it has less amperage and less capacity to charge batteries.

    It is a 100% recommended product.

    18650 Battery Storage Case DIY Box Power Bank Charger
    Нормальный бокс, учитывая цену. Выдаёт не более 1А.
    Нет логотипа "mi", задний торец салазок не входит до конца в алюминиевый корпус, надо подтачивать по периметру. Уже сломались две защёлки.
