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 Anker A1610 Battery (PowerCore 5K) offers an estimated 2,750mAh~3,250mAh to power devices.

How can I estimate the number of charges for my device?

To estimate charging cycles, use these formula:

Why does charging stop at 80%?

Your iPhone may automatically stop charging at 80% to protect its battery from overheating, as part of iOS 17's thermal management strategy. Charging will resume once the device cools down. Moving it to a cooler spot can help speed up this process.

Why is my phone overheating?

It's normal for devices to warm up slightly during wireless charging, particularly with heavy use like extensive gaming or streaming. Rest assured, this device meets international safety standards for safe operation.
