  • 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.

    -can charge a nook color from 0- 100 and a cell phone and there is still a little juice left too. small and fits in the palm of your hand. -dimensions are 3inches long, 2 wide, and 1 thick-simple to use -price, cheapest external battery over 6000 mah -
    -if it took less time to charge it would be amazing-the charging adapter is for the U.S
    buy it, its the cheapest 8800 mah battery pack I've seen around
  • Does not include Power Supply

    Huge capacity for the size/weight. For the few things I need to use it with, it doesn't add much size, but they will run a very long time.Can provide a wide range of voltages.Charges reasonably quickly for the capacity, and indication is clear.

    Wide range of adaptors.
    I would rate it higher if it included the AC adapter as pictured here (but not in the accompanying documentation). Even higher if it also had a car adapter. It also doesn't give a range around 18v/750ma so I don't know if my 19.5v laptop adapter would be safe, or if my 16.5v would work.

    The "voltage range" typically will mean, except for 5v (usb) devices, that it will be pack->adapter->device instead of pack->device. I don't know how they could keep it small yet allow finer setting of the voltage, but that is the only real technical complaint I have with it.
    As a USB charger, (if you have an 18v power supply available) I don't think there is any better pack for the money (under $10/1Ah). And the capacity is enough to run things for hours. They should include the recharger.

    I thought I'd give it a shot and found it to be a useful tool. Been in a situation many time where it came in handy. I sometimes work in low signal zones and this can cause the battery to drain faster than usual. This unit has kept my phone operational until I was able to plug it in to charge. The portability factor was important to me as well. The unit hangs there as I use it but better than not being able to use the phone at all.
    Not sorry that I bought it and recommend it to anyone who needs there phone and des not have long enough life out of the battery in their phone.
    Nice little unit for a decent price
  • Cheap and usefull

    It is small in size (like a medium lighter).It has a lot of charging capacity (maybe less than 3200mAh as it claims) and I use it to charge my Samsung Ace twice from 0% to 100% before empty.
    Probably the charge circuit had a problem but DX offer me a resend or money back as store credit as stated in the warranty, and that is a BIG THANK YOU for DX.
    But it if you need an extra battery for your devices, and don't you worry if something goes bad, DX is there for you.
