### ⭐⭐⭐⭐⭐ 







  
  
    Great portable battery
  

*by B***G on Reviewed in the United States 🇺🇸 on February 15, 2015*

I'm really impressed with this battery. The USB cable has a reversible plug, which is a nice touch that shows the company put some effort into the details. The cord itself is flat and easy to fold and put in my purse and I'm sure it would fit well into a man's billfold wallet as well. Even the packaging is nice. It also comes with a thin carrying pouch that keeps it from getting scratched. It really does have some nice touches.The battery itself is flat, probably about 2-3 times the size of a regular cell phone battery. However, it carries enough juice to charge a typical phone 2 times. It has an on/off button and a LED light with 3 different colors to let you know if it's barely charged, moderately charged, or completely charged. It charges cell phones at 2.1A which is very fast in this price range.There are other batteries that have more name recognition but I'm very happy I got this one.

    Lightweight Power
  

*by C***. on Reviewed in the United States 🇺🇸 on June 3, 2015*

This battery contains similar capacity to other batteries I've seen/used, however what sets it apart is its compact design.  It slips in the pocket of all styles of clothing and is virtually unnoticeable.  Yet the main reason why this device gets 5-stars is because of the service I received from Trond.  From the moment I contacted them about an issue with my initial purchase they were quick to respond, honest about the issue and replaced it without any of the usual headache of activating manufacturer warranties.Great work Trond!  I will be buying and recommending their products regularly!

    Don't hesitate to buy this!
  

*by B***E on Reviewed in the United States 🇺🇸 on August 9, 2015*

This thing just flat out WORKS! Steady and reliable (unlike others I have tried). Nice, slim form factor that does not bulge like other batteries in the "lipstick" configuration. Fast charging from a source, and rapid charging of my Samsung Galaxy S4 and Samsung Tablet. TROND's customer service and tech support are superior, and, let's face it: a product is only as good as its support. If I were buying something and TROND was a choice, that's where I'd put my money.
