I bought this mainly to use as a power bank, because 18650 batteries are often taken with me on trips for a headlamp anyway, and I needed one more cell. I have not intended to use the device as a charger. At least now I don't see such a need.
About 2000 mAh was transferred from the included battery to the mobile phone, i.e. the amount corresponding to maybe one day of economical use.
