Customer Ratings & Reviews

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 product. Used for my Disney Vacation. Even got it soked and still worked after it dried out. Love that it has a 1A and 2A output. Can get almost 2 full charges on my galaxy s7

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.

Slim. Compact. Holds two full charges! Excellent product for the price... I would buy again!

Bought the charger for my sons to charge their iPads. works great.doesnt take long to charge up

Great device, but can only charge my device once. I like the LED display with the battery life.

It is a standard battery backup / addition system but the percentage of charge remaining is great. Definitely helpful!!

I like the size of the charger it fits in my pocket . It charge fast and light.

Awesome i use it as a backup battery for my camera and my cell phone it charges my cameras battery pretty quick

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.

I would recommend this device highly. I always needed a portable battery/charger and this one does the trick.

this charger gets me fully charged twice and I have an iPhone 6+ so that's some power. Definitely a Best Buy.

I happen to get this while it was on sale and I've had no issues and I use it often. Charges my phone up fast.

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.

This was on sale so was a really great deal. Has a nice LED status screen and holds about 2 charges for my Note 4. Nice battery pack.
