-Amazing potential


This is my second request for a replacement to UnU:

"I purchased the UNU Black 14000 mAh Enerpak Vault Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets UNU-EP-02-14000BS on 7/30/2013 from This device failed after only two charges and would no longer hold a charge. I requested a warranty replacement of this product on 12/5/13 and was shipped a second device. I have finally had occasion to use the second device shipped to me and have found it has the same defect. After only two uses the battery will hold no charge at all. Only the single blue LED on the top of the device will blink when the device is plugged in, and the remaining two LEDs will never illuminate reflecting a charge in the device. It will work at most for 20 minutes of charging."

Hopefully the next one they ship me will actually work... Time will tell. But I wouldn't recommend this to anyone.
