Anker Power Bank (10K, 22.5W) B2C - UN Black Iteration 1, A1257

Anker Power Bank (10K, 22.5W) B2C - UN Black Iteration 1, A1257

Q: Why does my power bank provide fewer charging cycles than expected?

During the charging process, there is a 30% to 45% capacity loss due to the battery cell and conversion circuit. A fully charged A1257 can deliver about 5,500 to 7,000mAh of power to your devices.

Q: How can I estimate the number of times a device can be charged?

Use the formula: (Total capacity of the power bank's battery × 0.65) ÷ Device battery capacity ≈ Number of charges.

Q: How long does it take for the power bank to recharge?

It depends on the charger's power and the ambient temperature. The A1257 model, when using an 18W PD charger at 25°C, takes about 3.5 hours to recharge.

Q: Does the power bank support simultaneous charging and discharging?

No, it does not support simultaneous charging and discharging.

Q: Can the power bank be taken on an airplane?

Yes, it can be carried on an airplane.
