    This device can do the following:- Charge phone or other device via USB using power outlet (110~240V)- Charge phone or other device via USB using a 18650 battery as power supply- Charge 18650 battery from power outlet (110~240V)- Charge phone batteries (using the adjustable pod and clamp) from power outlet (110~240V)All above tested and working.- It also has a switch that indicates that it can charge a phone battery from a 18650 battery.Not tested yet.
    - Do not forget to buy a flat pin adapter.
    - It's a very useful device. Even though it does not excel at anything in particular, it has a lot of uses and functions.
  • Great for emergencies

    -Charges my phone really fast! -The battery comes with a cap so that you don't damage the microusb. The cap is attached to the battery itself by a string so that you won't lose the cap itself.- The microusb is long enough even though my phone has a case of moderate thickness on it. (I'm not sure about otterboxes).- 4 little lights on it indicate when it's done charging and when it has no more juice left to give. - Very nice and compact size. I can easily fit it in my purse or pocket.
    I'm currently testing it out and had my phone at 64% on standby. It's been charging for over an hour (expressing that it's only at 1 charge light for a good 30 minutes) and my phone is already at 94%. I'm confident that it can charge my phone to full.
    If you know you'll be out for a long day and/or will be using your phone a lot, this should be enough to pull you through.
  • Works

    Dimensions are really small, cannot believe it has the capacity it says but time will tell.
    It takes a little time for the device to register being charged but it registered both on my SGS II and my Nexus 7
    Really cheap and does what it says on the box. Not bad for this price.
  • Nice but chinese instructions?

    plugs into wall outlet, I believe it is 110-220 compatible as I am using it through 110. Securely holds battery in place and has a wide range between connections to allow for many types of batteries.
    Should be auto polarity but can't really tell if it is functional as so. Also can not confirm if it has any safety features that will disable the charging when complete.
    Being the second device of this nature I've bought, the first being a usb plug-in it has definitely been worth the money.
    I recommend researching the device for the instructions to make sure it is what you need.
  • Awesome charger!

    It really prevents my OVERVOLTED and OVERCLOCKED to 1,5Ghz HTC HD2 to discharging when i playing Backstab HD with 100% brightness and connected ICQ through Wi-Fi in background!!! And it charges my phone when screen is locked. Looks like it gives us more power then the regular computer USB port! I`m using 1.2V AA rechargeable batteries (sku.12720) with it. And i think there will be a greater charging results with an 1.5V batteries, but i haven`t much money to buy every day a new pair of batteries.
    Also there is a good quality cable (much better then ones i bought there for $2.32 or something)
    Build Quality of this charger is even better, then on DX photos! It looks almost like genuine belkin or apple products!
    And finally, the font of "EMERGENCY CHARGER" title looks like the font of ER TV Series title, so it`s a big plus for fans like i am.
    Yes, the Data+ and Data- on the USB port are shortened like in original charger! It means that our phones will try to take all power they needed, without any limits.
    If the red led is not lit when phone is connected and charging is enabled, or it lights very dimly then you just need to replace batteries.
    That gadget is absolutely worth the money! For $5.30 you get an USB porrt in your pocket with good data cable (yeah, it can works as usual data cable!).
