Anker's power banks and chargers are engineered to address the common concerns about battery depletion and charging inconvenience. With a 20,000mAh capacity and the ability to distribute 87W of power across multiple devices, our products ensure consistent, reliable charging for all your electronic needs, even during extended use.

The capacity reduction during charging is a normal phenomenon, as there is a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) can offer an estimated 11,000mAh to 14,000mAh of power to charge your devices.

To estimate the number of charges for your device, you can use the formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity ≈ Number of Charges. For example, charging a 3,000mAh device using a 20,000mAh power bank would offer approximately 4.33 charges.

The recharging time for the power bank itself depends on the charger's power and the ambient temperature. The A1383 model, when using a 30W PD charger at 77°F (25°C), takes about 4.5 hours to recharge fully.

Anker's commitment to quality, innovation, and customer satisfaction is reflected in our comprehensive product lineup and industry-leading warranties. Experience the difference with Anker – where power and convenience come together seamlessly.
