  • Nice but chinese instructions?

    posted by righteousrob

    plugs into wall outlet, I believe it is 110-220 compatible as I am using it through 110. Securely holds battery in place and has a wide range between connections to allow for many types of batteries.
    Should be auto polarity but can't really tell if it is functional as so. Also can not confirm if it has any safety features that will disable the charging when complete.
    Being the second device of this nature I've bought, the first being a usb plug-in it has definitely been worth the money.
    I recommend researching the device for the instructions to make sure it is what you need.
  • Very good

    Works great after you figure out the required stance of the pins. The charging speed is fine i guess, it takes about 4-5 hours for an empty galaxy s3 battery to fully recharge.Supposedly it has an 'overcharge' protection of some sorts, which means it will stop "charging" your battery after it reaches 100%.Its easy to fit in your pocket to take with you pretty much anywhere.It also has a usb port on top of the charger to connect another usb device.The screen is clear, easy to read.
    My Galaxy s3 stopped charging after almost 2 years of service, so i was forced to get another battery. This kit popped up and seemed perfect; cheap, a new battery and a charger.I havent used the usb port on the charger.
    Works perfectly once you figure out the pin setup for your battery. Mine was on the 2nd and last pin for my galaxy s3. The charging is fairly quick and the whole "kit" is super easy to take with you
  • Nice to have

    - perfect if you have a spare battery- charging indicator is bright and useful, it will really caught your attention when it is fully charged- very light- i like that the plug can be neatly folded to avoid scratches to your other electronic devices when stored inside your bag
    - the charging indicator can be a bit smaller, since it so bright that it can serve as a night light
    - this is something you really need if you have several batteries with your Samsung Note 1 since you can use your phone normally, while the spare battery is charging
  • Price / Quality very good

    It's very easy to use. Lighter than most of the other back-up batteries and stylish. Really fast charging. Takes around 4 hours to fully charge.
    I also used it to charge ipad mini works perfectly fine.
    Definitely suggested, I already ordered another as a gift to a friend. Lifesaver especially with the battery problems with iphone 5s

    -can charge a nook color from 0- 100 and a cell phone and there is still a little juice left too. small and fits in the palm of your hand. -dimensions are 3inches long, 2 wide, and 1 thick-simple to use -price, cheapest external battery over 6000 mah -
    -if it took less time to charge it would be amazing-the charging adapter is for the U.S
    buy it, its the cheapest 8800 mah battery pack I've seen around
