usb power bank Customers Reviews

  • Great battery, can be very useful sometimes

    posted by yuksas

    Good size, easily portable, not heavy at all. Looks better than i thought. Capacity is as it says. Has a led light, which can be useful sometimes to see in a dark. Also u can see when it is charging from the sun with 4 blue led lights. Two usb ports with diffrent power output.
    Great battery for all kind of usb gadgets, last long, useful. I use it for usb light, usb warm gloves, and with my usb speakers for outside use, sometimes to charge mobile or photo camera.
    I am happy i bought this one, and its good to have it.
  • Good priced battery backup

    Compact size, replaceable battery.Has red LED (not mentioned in description) that comes on when charging.
    I am using these battery packs with small solar panel to charge batteries during the day. Seems to work well, then at night I plug my iOS device into the battery and it recharges my phone/iPad. Works well. Nice compact design.
    Very good value for a nice battery in compact case with a cable and carrying strap. I really like it. Once the battery is charged, just plug in your USB device and it will be quickly recharged. My iPhone 5 went from 40% to 80% in about 10 minutes.
  • battery backup that Works but stick with 3000mAh or less 18560s

    Small, compact easy to use and change batteries. It works... I got this a while ago and was waiting on all my different types of batteries to show up before giving a full review. This works best with 3000mAh 18650 batteries or less. the 3200mAh ones do not fit into the battery compartment well enough, extremely tight fit. This unit is extremely simple to use and can charge your 18650 batteries as well. I leave 3000mAh battery in it and keep a couple in my bag for when I'm out in case I need to recharge my phone a few times. I get about one full charge with a little left over in my Galaxy S3 with this setup.
    The flashlight addon that comes with the case is pretty handy and comes in use. I keep that in my backpack for those times that I just need a light to be able to get around. I use it more often than I would have thought I would have.
    If you want to keep your devices charged on the go in a small form factor, this is your easiest option. Just keep in mind that this case is not waterproof. It works though, fairly well. Don't expect it to be durable though.
  • Very useful gadget

    Powerful external battery with two USB outlets ( 1 A and 2 A). I use it to charge my Apple devices while working with them. I got the white/blue one which looks very nice. It charges my iPad several times and is still half full, if the power status lights are correct.
    A small manual would be nice. Otherwise it works as advertised.
    Cheap but powerful with a nice design. If you need extended power supply on the go, this is the right power bank for you. It's far superior to those 18650 powered ones.
  • Very good portable charger

    Good looking Simple to use Four-bar working battery fuel gauge Moderate efficiency of 68% if phone charged to full, better if charged partitially. Very sturdy. Compact size compared to other 2x18650 housings.
    I own several portable batteries and this is clearly the best. This can't fit protected batteries, but this shouldn't be an issue since it has overcharge and overdischarge protection built-in. I'm using SKU: 180030 Panasonic batteries which stores the highest capacity of real 3,4Ah in 18650 casing.
    This little thing can store a lot of energy in small size with quality batteries.
