iphone 4 battery charger Customers Reviews

  • Well built

    posted by fitzie

    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 item, but last item that i ordered from dx

    Great item, but this is the last time that i ordered something from DX! It took more than 60 days to arrive, i open ticket service before 3 weeks and no one answered till now. Everything is too slow with DX. I do not know what is going on, but dx is not like before.
    If dx continue to treats customers like this, it is not good for you. I loved dx and recomended it to all my friends, but now i stop doing that.
    Thanks for all, see you again if you get better.

    this is a very useful emergency charger. it works quite well. each slot has plenty of space to insert protected 18650 batteries (other chargers are too short to insert protected batteries).it has 3 led to indicate level of chargethe big white led can be used as emergency light
    i found instructions on internet and i posted some photos. now i know what the jumper does.
    useful, cheap and sturdy. recommended.
  • 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.
