    Cell phone always has a charge
  

*by L***D on Reviewed in the United States on March 3, 2016*

This is the best slim charger, I can put this in my bag and keep it moving.

### ⭐⭐⭐⭐⭐ 







  
  
    love the convenience
  

*by D***5 on Reviewed in the United States on September 5, 2015*

Only used it once to top off my battery went from 49% to about 79% in about a half hour. Looked like it used half the power in the charger but I will see. sometime batteries get better as they get older. Only thing is that I wish I would have Gorton the red color.

### ⭐ 







  
  
    Horrible product! Do Not Buy!
  

*by J***N on Reviewed in the United States on March 21, 2016*

Horrible product!  Do they buy! Looks nice but would not hold a charge.  Would not charge iPhone 6 either. Weird hookup piece added to the order to try and make it work. Awful!
