  • Extra Power on the go

    posted by omaki

    Small sized, smooth, feels like rubber at touch, rounded corners. Easy to use, just charge and go. It claims to be 5000mAh, it means 5 times the charge of an average cell phone battery. Or full charge of a tablet battery. The indicator lights are very handy. There's two output usb ports (5V 1A, 5V 500mA). I'm not sure if it really has 5000mAh capacity. I've opened it and there's two unbranded, in parallel, 2500mAh cells, which means 5000mAh.
    I travel a lot and extra power is always handy. Not all buses, trains, or airplanes has power outlets to charge my devices. It gave more autonomy to my cellphone, my tablet, my mp3 player, and my netbook. I'll buy an 10,000mAh next time
    If you travel and you have electronic gadgets, or you are a heavy user geek, buy it.
  • Good bang for you buck

    Have owned this and used this for over a month now and puchased due to the poor battery life of new smart phones. The battery is a very solid build (does not feel cheap) and can usually recharge my phone twice to almost full.At work I usually have it or my phone charging always then at the end of the day I dump both into my purse. It has a red LED when charging.Both connecting ports seem very sturdy and it hasn't come unplugged when charging after I've thrown it in my backpack or purse.
    I'm a little concerned when taking this on an airplane for our trip hopefully security wont have any problems with it.
    I'm overall very happy with this purchase, puchased two portable batteries and this by far was the better deal. It is heavier than my cell phone so it adds a bit of weight to whatever your carrying it in.Its small enough to fit in my tiny purse :)
  • Not really working well

    Compact shape, dual led info about charging/full
    good idea, missing results
    after first slow charge to full (green led) and first discharge to Cphone (charged up to 70% of 1750 internal lipo) ended charging, than after second charge of this unit, this item does not charge Cphone anymore, by other way phone is charging well, now after full it charges only some things by usb, not the phone. Voltage seems OK, led lights work from this port. But for me after one cycle does not work!
  • 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.
  • 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.
