  • Cheap, effective battery

    -Cheap-Well made-Small-High reserve for the size-Little light up LEDs that show how much charge is left in intervals of 25% when you push the button
    Great little battery I originally bought for a portable radio setup I was building, but then I found that my Blackberry can use it as a charger.I find it to quintuple my phone's battery life when used.
    For the price, it's great. It'll up the battery life of your portable devices by a whole lot and is small enough to keep in a pocket for when you need it. Get it if you need a nice external battery!
  • This is a great, pocketable power source for charging smartphones

    These (I bought three) are very useful when my two sons run out of smartphone power in the middle of nowhere. I have one as well for the same reason.Very easy to use with devices that are charged via a USB cable. It just inserts between the USB charger and the phone (in essence), although I tend to charge them separately, often from PC's USB ports (as they are handy).
    Please remember to turn off the device when done as there is some drain from the internal inverter circuitry (and LEDs) as long as it's on.The 6000 mAh capacity is related to the cell at roughly 3.4 V, so the 5.5 V output of the unit will be about 3300 mAh, estimating a 90% inverter efficiency. Still, it's 20 Wh of power in a slim case.
    Nice package, I would buy more if I needed one.
  • Good one!

    It fits into my pocket. That was an intention - I can put my Galaxy S4 with this brick simultaneously at man's jeans pocket. And it charging while not in use, especially useful during a travel. Via direct cabel connection it can charge even with 1.9mA (Galaxy S4) with good cabel (1A documented).
    The good ideas implemented about auto switching on and off. If you plug a charger to it, it is turned on. If you unplug - it turned off. If you plug a phone via cabel - it turned on, and stay on for a 5 min if you unplug a phone. If you put phone on qi - you need to press a button to turn it on. It stays awake for 5 min without qi connection. You can not charge via wire while bank connected to charger itself... But interesting: if you charging via qi - connecting charger to bank disconnects from qi, but if you put phone away and back on qi again - it can charge, and can work as usual qi charger, connected to AC. (sorry for mess, hope you understand)
    I'm pretty much satisfied, good device. Good price. Just note that black color also available, I've noticed it too late.
  • Overall great for the job it has to do

    All around very good built, no loose parts inside (only noise while shaking is from the on/off button, which is ok), doesn't make any cracking noises while putting twisting pressure with hands, made out of hard plastic, clear and understandable interface, and comes with a USB cable with changeable heads.
    Could have had voltage and amps marked on the outputs (output 1 5V/1A, output 2 5V/2.1A) though it's written on the back.
    Great item for camping, outdoor work, long bus rides and any other situation that you don't have an available plug, just charge it through the night or let it sit in the sun during the day and you're all set to go.

    it works great on phones and charges good using iphone 3gs. its not expensive for the mAh you get.metal makes it durable and it makes for a very strong tube.
    it looks like a dildo, please change the form of the charges. its a bit embarrasing using the charger.
    it works great on phones with a low power usage but it doesnt work on higher end smart phones that need higher charges.
