Customer Ratings & Reviews

I work in the oil field. I sometimes stay in the field late. And with my new portable Samsung b3100 charger I stay connected . Never worry about my devices running out of battery .Great for work or outdoor activities .

This charger is great for keeping my devices charged. My cell phone sometimes does not stay charged so this device keeps my phone operating until I can charge it at the end of the day. Great little device to have.

I haven't had to use it too much but it is great in case of emergency or long trips with no charger

My new best friend the battery life will last for 4 to 5 days. Allowing you to pull a charge at least 10 times before you need recharge.

Very impressed with this product. Thanks to my portable charger, I was able to enjoy the concert I attend and record a lot of videos without having to worry about my battery dying.

Fast charging, easy to use, holds a charge and charges your phone quickly

Great portable charger from Samsung, it slim, light and it chargers fast.

It has no problem charging my Note 4 and Tab 4 (which I USE for work and play DAILY) and its size means I can throw in my pocket like a pack of gum.

Its the lightest one I have ever found. Love it. Its perfect for my Galaxy Note 5 phone.

This unit keeps the Galaxy 5 charged for a good duration. Can't go wrong with this product.

Maybe my expectations were too high. It charged my cell phone overnight, but when I wanted to put a charge on my phone at the airport, and use the phone at the same time, I was hoping for a little better results. I wish there was a better way to tell the level of charge remaining in the battery pack.

Product does what it's supposed to and I get more than one full charge out of each battery load

So far so good. Keeps my phone charged when I need a charge when I am on the go. It's very convenient and effective.

My phone always is charged. I would recommend this to a friend.

I love the thin samsung back up charger battery more light carry travel and good full for one time.

used this while on a trip last weekend, was great to charge up the phone while out and about with out access to electricity. Goof for one whole charge and more... even charges at a decent rate, thought I'm sure there is better out there

Excellent device to carry along for the time when you just need that extrasolar for your phone

I love this.produxt because my phone usually dies toward the end of the day and I am rarely around a.plug in. I can charge my phone where ever I am with this handy little device.

Very useful I'm sure there bigger ones avaliable. It does the job just fine.

I have a Samsung note, Mophie does not make battery packs for this so I had to try this battery pack. It was small, compact, easily charged and attractive.
