  • Convenient usb charger for an emergency.

    posted by chrysoula

    It is of acceptable build quality. Mine came with an adapter just like the picture. It can definitely charge a device, I tested it with my cell phone, my e-reader and even my e-cig battery.
    Very convenient size.
    It's cheap, I know, but it should be a little more expensive and have a switch for charging/decharging. Also, a cut-off for when current flows the wrong way.
    You can have it with you on your vacations, and be sure that on an emergency your usb-powered gadgets won't be left uncharged.
  • Good battery pack

    posted by Phoxy84

    It's a nica small emergency battery pack which can be connected with USB. I use it in emergency's with my mobile phone. Just take your charging cable with you and power it on. You see that it works because the charging led on my phone will turn on.
    It works really good, in a few moments my phone had enough power to startup.
    it''s size is gooed, the pack just slides in my bag without taking a lot of space.
    It's useful that is can be charged from USB. I can charge the battery from my USB wall charger of pc.
    The capacity is good enough to give my phone some juice. I don't haven't tested how much it will charge my phone from zero.
    A must buy for someone who wants to operate electronic gadgets outside for extended periods of time.
  • quite bright

    Small, very bright. Usable with nearly any USB power source such as laptops , battery chargers and USB batteries.The light is relatively unfocused so it good for activities near the light only. One one of my tablets it will illuminate my face when using the front camera, not the room.
    Uses 120mA at 5V
    Handy, but keep it in a safe place.

    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!
