Anker Power Bank, 20,000mAh Portable Charger with Built-in USB-C Cable, 87W Max Fast Charging Battery Pack for Laptop, 2 USB-C and 1 USB-A, for MacBook, iPhone 15 Series, Samsung, Switch, and More
- The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) offers an estimated 11,000mAh to14000mAh to power devices.
- To estimate charging cycles, use this formula:
- (Power Bank Capacity × 0.65) ÷ Device Battery Capacity Number of Charges.
- For instance, charging a 3,000mAh device using a 20,000mAh power bank would offer approximately 4.33 charges.
- It 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.
