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.

What is Trickle Charging Mode?

Trickle Charging Mode lets the USB-A port charge low-power devices like watches or earbuds. Turn it on or off by double-pressing the button. When enabled, a small blue dot appears, and a low standby output is normal.

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.

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.

Why is the power bank's output lower than expected?

Power bank's output depends on the power required by the connected device. As the device's battery level increases, the required power decreases. For example, with an iPhone 16 Pro and its original charger, the power drops to about 6W at 70% battery.
