battery powered usb Customers Reviews

  • Good product for its price

    posted by pleh77

    Good product for its price. After receiving I loaded Phone and E-book. After 20 hours of loading on sun its loaded completly. Low weight and its very useful in extreme travelling! Also it can be loaded from electricity and have two output with 1 and 2 A. Also robust housing allows not to worry about its safety and impact. Almost any mobile can be charged. In general, it is recommended for travelers, tourists and lovers of single journeys. Will order more for friends, as its weight is very small for such technical parameters.
    Very reccomended!
  • 18650 charger and emergency power bank for phones and other gadgets

    It charges 1 to 4 x 18650 battery.It can be used to charge a phone with as little as 1 18650 battery.It has battery indicator for each battery.It has charge indicator for each USB outletIt takes protected and unprotected batteries, so you can use old laptop batteries.If you use unprotected 18650's this device protects the batteries against under- and overcharge.
    Why not make both USB's 2A?
    I love it, great device, never worry about phone battery when this is in your bag!
  • Works well but poorly designed

    This provides a backup power source for any USB chargeable devices. I can be charged from a USB port or the battery can be removed and charged in a 18650 charger.
    I would prefer a different color than the bright lime green plastic and the included short USB cable came in purple! I am not using it as a fashion stating device so I guess that is acceptable but . . . YIKES!
    A great backup source for those times when you phone goes dead part way through the day.
  • very nice power bank

    This is a very nice gadget for your recharging when you travel. It charges with you usb or electric network and sun. It takes a while to fully load as it is a large battery, but then I can load my phone several times to 100%.Extremely good value for money. As said, the charging itself takes a while to get the full 4 lights led, as in fully charged. But hanging my phone on it, the phone reloads very fast. I also recharged a tablet etc. Charges very well. Reloading by sun is possible....but does take forever, so that's definitely a case of emergency. You can load till one led and recharge your phone. That works brilliantly.
    Very good product. I reordered as I want to give it as present to my friends. Love it!
    Value for money. Great product. Can't go wrong with this for you phone. And other energy absorbing things!
