usb emergency power Customers Reviews

  • Very Usefull

    posted by daniguns

    - It's very usefull- Quality it's OK- The outlet is an USB port you can use it almost with every electronic device in the world
    I didn't need the cable because I do not have a Samsung but even with the cable it was cheaper than the other chargers.The flashlight is useless... but you can buy a small USB rechargable flashlight and charge it with this.
    I really recommend it if you are going to be away for a couple of days. It's really cheap and it can save you (My GPS runned out of battery and I charged it with this device)
  • Perfect fit for your bag for emergency usage

  • Is it really useful? Can be!

    I bought this Mico USB Emergency Power battery because I have an HTC smartphone that I have to charge everyday.Sometimes, however, I cannot do so and that is when it is useful to have this battery with me.It isn't too big, and you can charge it with the cable of your mobile phone.It works and the lights on the top indicates if it is loaded or not, what is very useful.
    I do not use it as often as I thought I would, but it helped twice last month.
    Good quality for the price, I would'nt pay more than the 12$ mentionned.
  • Cheap and effective

    The best solution for this money.
    Charge the phone and Samsung b2100 Sony Xperia Acro S. Charging the battery life of mobile devices comes from both the battery and on the AA-batteries.
    11 mAh for $30 - that's a lot, lot cheaper than counterparts Li-Ion batteries. A great solution for long autonomous hikes, geocaching and Ingress game.
  • 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.
