Why is my power bank providing fewer charges than expected?

Energy loss during charging due to inefficiencies in battery cells and circuitry results in a 30% to 45% capacity reduction. A fully charged Anker 25,000mAh power bank typically delivers about 13,750 to 17,500mAh.

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

To estimate the number of charges, use this formula: (Power Bank Total Capacity × 0.65) ÷ Device Battery Capacity. For example, a device with a 3,349mAh battery can receive approximately 4.8 charges from a 25,000mAh power bank.

Does it support pass-through charging?

Yes, the power bank supports pass-through charging. However, it requires a charger rated at 20W or higher, and the input power must exceed the output power to enable this feature.

Is it normal for the power bank to display ""No Recharging Mode""?

Yes, this is normal. When the power bank discharges at high power, its temperature increases. For safety, the protection mechanism temporarily delays recharging until the temperature lowers, but it will continue to discharge during this period.

How do I adjust the length of the retractable cable and use the short cable?

Pull the retractable cable to your desired length and tug gently to lock it. To retract, pull slightly and it will retract automatically. For the lanyard, press upward to extend and downward to secure it in place.
