Why does the digital display show the battery capacity decreasing rapidly while charging a phone?
Anker Power Bank has a battery capacity of 5,000mAh. Due to efficiency losses in the conversion circuit, its rated capacity at 5V is about 3,000mAh. Therefore, it is normal for the product to lose about 3% of power per minute during use.
Why is my power bank providing fewer charges than expected?
The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged 5,000mAh Anker Power Bank offers an estimated 2,750mAh to 3,500mAh to power devices.
How many times can the product charge devices in power bank mode?
In power bank mode, it can fully charge an iPhone 13 once, provide about 0.9 charges for iPhone 14/15, about 0.8 charges for Samsung S23, and about 0.7 charges for S23 Ultra.
