It's working great so far
Really high quality workmanship
Charges iPhone and iPad without a problem
Maybe the weight, but at 20.000 mAh it is understandable

metal cover
large capacity
small dimensions
can not be used to permanently power something with low consumption, for example 30mA, the power bank turns itself off at such a low consumption
the above is a big disadvantage, although I understand that the purpose is probably to protect the bank from being discharged by a very small current

A big disappointment for me, the first powerbank was all broken. After the complaint, another one was sent, visibly already used and scratched, so it is obviously susceptible to this. Unfortunately, the biggest problem is the cold, because the power bank is made of metal, so when used in a jacket pocket, it turns itself off because of the cold. I wanted to use it in a heated jacket, but I had to reach for the plastic version from Alza, which works fine.
