## Customer Reviews

### ⭐ Melted
            
*by T***. on June 15, 2017*

When i got it, it was weirdly packed. Box was opened, i put it outside and 30mins later it looked like it was about to explode.
  

### ⭐ Lying about the capacity.
            
*by A***O on January 12, 2018*

Unit swelled in the sun after a week.  Barely functioned after that. Didn't work well to start with.  30k mAh would be huge. It dose not perform to that.  300k mAh is not even close to possible.
  

### ⭐ Terrible
            
*by J***D on August 4, 2017*

This is a very cheaply made product that is nowhere near what they described.  It says 30000mha but it is less than 2000mha.  I would not purchase this product again.
