I'm seeing a lot of claims of not matching capacity in the surrounding reviews (of this and other powerbanks). Don't trust the writers - at least for this Vention powerbank. They mean well, but they don't understand that batteries run on their 3.7V while USB runs on 5V. Alza has a nice article about this called "What is the real capacity of a power bank? “. I recommend everyone to read it. I measured this power bank (I bought it with a claimed capacity of 30.000 mAh) at about twenty charging and discharging cycles and it corresponds to the declaration exactly, i.e. has 30.000 mAh at 3.7 V, i.e. approx. 22.000 mAh at 5 V. At the same time I bought a 30.000 mAh AlzaPower and it is practically the same (i.e. as well).
the capacity corresponds exactly to the declaration
nice, well processed
