1. Product discharge quickly when in use for all 10K Power Banks:

External batteries normally give only 60%-70% of their capacity to other devices. Approximately 30% of the battery capacity is used up by the powerbank itself for the circuitry to actually generate the charge to the device it's trying to charge. These efficiency problems affect all electronic devices no matter which brand you are using, and a fully recharged Anker PowerCore Fusion 10K shall generally be able to give only 2 charges to an iPhone 12 with a 2815 mAh battery. The usable capacity is 6000 mAh.

If the above reason is not justifying the current efficiency of your powerbank, then please try another cable and devices/phones.
