iphone emergency battery Customers Reviews

  • Excellent product for that price

    posted by theseven

    - Cheap- 2A output- PCB contains battery protection circuitry (deep discharge, overcharge, short circuit)- Bypass diode from input to output- Step-Up converter efficiency of 70-80%- Trickle charges deep discharged batteries- Doesn't start charging if battery voltage is above ~4.15V- Fuel gauge isn't all the way off (but tends to be a bit too optimistic)
    Some data points:- PCB looks like the 2A output version, bottom picture here: http://i1138.photobucket.com/albums/n525/yulunyan/55.jpg- Battery charge completion: 4.20V- Powered off battery discharge current: 0.5mA- Powered on (idle) battery discharge current: 4.6mA (including LED)- USB output voltage (idle): 5.21V- USB output voltage (3.55V battery, 1.63A load): 4.57V (efficiency at this point: ~72%)- USB output voltage (4.1V battery, 1.75A load): 5.16V- USB output voltage (4.1V battery, 1.95A load): 4.61V
    Awesome product for that price, apparently well-engineered electronics.I'm really curious what that jumper on the PCB is good for.

    I especially liked this because it utilizes 3aa batteries instead of 2so the overall output will be a bit more than the normal 2 battery ones. Seems to be well built and easy to charge anything that has a 5volt charge rate. I've used it for my iPod touch and it was at 50 percent and it fully charged it buy it if you want a charger with a little extra omph it may be slightly bigger but so what!
    Could come in black but that is just my opinion otherwise im happy with it
    About time I come across a charger that has more capacity than the 2aa tyPe so buy this and you won't be dissatisfied
  • Great portable charger!

    Fast chargingUses standard mini usb connector for charging2 USB output ports (1A and 0.5A)Simple LED to indicate charge level
    We used this on a recent trip to the US. I had a Samsung S3, couple of "burn phones" (arrghh - who wants to pay roaming fees), an iPhone and iPad. We used this to charge every device at various points in the trip and found it very capable.
    Extremely good value when you want to have portable power for charging devices.
  • A must-have for smartphones

    posted by cblunardi

    It can charge my Razr I (2000mAh) 20%->95% twice, the aluminium alloy on its body make his design really nice, his size combinated with his included micro usb cable size are great for pocket charging. The usb/microUSB ports let it be charged with any phone charger
    The battery itself seems to have a good quality, I thing it will stand for at least one year
    As said before, a must-have for smartphone owners that use all of it capabilities
