Purchased for Meta Quest VRK. As long as it is charging, the Meta Quest does not discharge (or drop in charge level) while in use. After 4-5 hours in the meta quest, the power bank is half-discharged and takes quite a long time to charge itself (which is understandable with a 20K mAh capacity).

Charges fast, so that VRko doesn't have time to discharge
