    Works well. does fully charge a galaxy note 4 on one full charge but that's it.but good enough to keep you going all day when you don't have access to a receptacle or lighter to use chargers

    I bought these to power my Sony A7R II for videos using a Tether Tools Case Relay battery solution. The 4000mAH version is great because they are so small but is roughly equal to 3 Sony NP-FW50 batteries, and they can be hot swapped using the Case Relay solution. These were on sale for ten dollars when I purchased them at Best Buy so I grabbed 3. Easy also to carry on a bag or pocket without adding the weight of a 16000mAH brick.

    Great for 1 full charge and a little more. I really like the percentage meter so I can get a more accurate idea of how much juice is really left.

    bought for my sons school trip. However I have used many times after. Easy to read display charge left. For just a charge, can get about 2 full charges out of it. Best to use as a backup and plugged into phone while using. helps maintain the phone charge and raise it during use and lasts much longer this way. Got on sale..for $9.99 it has been useful many times.

    It's a good size and built well. It has enough power to charge a phone or whatever, although more capacity sizes are available for even greater charge power. A good item to have on hand when you need to quickly charge something and have no other way to do so.

    This charger is easy to use and transport in my purse or pocket. I have an older Android phone so it needs to be charged pretty often. Love this charger.

    Does exactly what it is supposed too. The battery stays charged for a long time when not being used. The charging sticks battery drains while not in use.

    Bought this on a whim since it was on sale, actually ended up buying 3 and they would probably be the best external battery packs that I own. They are quick to charge and come with 2 ports. Good thing is that it has a digital display to show you exactly how much of the battery is left. So glad I took advantage of them being on sale and grabbed 3!

    The battery pack is quite good. The visual indicator is useful, although I feel it discharge's quite quickly.
