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.

How long does it take to recharge the power bank?

The recharge time depends on the charger's power and the ambient temperature. Using a 100W or higher charger at 77°F (25°C), it typically takes about 2 hours to fully recharge the power bank.

How to turn off the screen?

The screen will automatically turn off after 10 seconds of inactivity. Alternatively, you can manually turn off the screen at any time by pressing and holding the button for 2 seconds, whether the device is active or inactive.

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.
