Why is my power bank providing fewer charges than expected?

During charging, about 35% to 45% of energy is lost through the battery cells and power conversion circuitry. As a result, a fully charged Anker Nano Power Bank (PowerCore 10K) provides approximately 5,500 - 6,500mAh of usable capacity.

Can I bring Anker Nano Power Bank (PowerCore 10K) on an airplane?

Yes, this power bank is flight-approved and complies with air travel regulations in the United Sates and most countries. However, it does not have China's 3C certification and cannot be carried on domestic flights within China.

Why does charging stop at 80%?

Your iPhone may automatically pause charging at 80% to protect battery health as part of iOS thermal management. Charging resumes once the device cools down. Moving it to a cooler spot may help.

Why is my phone charging slower than expected?

Charging speed may be affected by your phone case, device temperature, and usage during charging. For best results, remove the case and avoid heavy use while charging.

Does this power bank support iPhone models earlier than iPhone 15?

Yes, it supports iPhone models earlier than iPhone 15. However, the built-in USB-C cable cannot charge Lightning devices directly. A separate Lightning cable is required.
