Can only advise against it!

Negatives:
- To longer delivery. It took almost 2 months ...
- Poor packaging. The packaging was just a foam bag
- No 30 000 mAh. That there are no 30 000 mAh was already clear to me, but the battery holds its capacity not
- 1. Use about 12000 mAh. Actually perfectly fine, my phone could charge almost 4 times.
- 2. Use approximately 9000 mAh.
- 3. Use about 6000 mAh. Only 2 boots with my phone. That means the Power Bank is very poorly finished, and therefore not hällt their capacity. This makes the product unusable

DO NOT BUY !!
