3000mAh External Power Bank [Black] Vority Vigor 3S Lipstick-Sized Portable Battery Charger for iPhone 5S/5C/5.4S... iPod (Lightning Cable not Provided); Samsung Galaxy Note 3/2 S4/3/2; Google Nexus, HTC Sensation, One X/V/S/EVO; LG, Motorola Razr and other USB-charged devices (Includes Micro USB Cable) - 1 Year Warranty

Charges ridiculously quickly. Holds plenty of power for my wife's phone (2100mAh), mine (2400mAh), and much more. Unless the LEDs indicating power level are grossly inaccurate, we've never come close to draining this backup. It's also blue, which is tacky but fun! Gets the job done, surprisingly well. I'm not sure what the lifetime on the internals will be, but that's a risk you take with any rechargeable battery pack, and doesn't seem to correlate to brand or manufacturer. I would definitely recommend this to friends and family who want backup and don't demand a battery case.

Great to have this around! It only works for about 2 full charges before you need to recharge it, and it loses its charge after about a month so if you forget to recharge it and then need it it will be dead, but it's small and easy to carry. The USB port seems a little wiggly, but it could be my phone, not sure. Sometimes it has trouble connecting, but you can use your own phone charger cord, attached to the battery, if that happens.

Love this!! It is very handy to carry in my purse, it offers a quick charge and a pretty decent one at that! I like that it comes with its own 6 inch cable, though I had to buy and extra one since I have an iPhone. Price was a bit higher than others out there but has since gone down. I purchased it despite the higher price based on reviews and have since bought three more as Christmas gifts.

It is a good size and good value. I like that it displays how much power is left, but not that when not in use it loses charge faster than other more expensive brands I have had.

this is so cool i have always wanted one and i finally got to try it i tell ya it sure does come in handy when you are out and about and your buttery is about to die it is a live saveri love it

Doesn't work. Seemed to kind of work at first so i didnt want to return it. good price... then it just never worked again. would not recommend it

LOVE this! Sometimes all the airport charging spots are taken so this is a life saver

Weak. Doesn't hold the charge.
