The charging speed depends on whether the charger and cable can meet the power bank's requirements. Using a 20W fast charger, the power bank can be fully charged in approximately 2.5 hours.
Can it charge low-current devices like earphones?
Yes, this power bank features a low-current charging mode.Simply double tap the power button to enter this mode to charge small electronic devices and double tap again to exit!
Does it support charging while discharging?
Yes, the power bank supports pass-through charging with a max input and output of 5V/3A. Note that it does not support simultaneous charging and discharging for laptops. For longevity, avoid charging your phone while charging the power bank.
How can I estimate the number of charges for my device?
To estimate charges, use this formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,877mAh battery can receive about 1.67 charges from a 10,000mAh power bank (10,000mAh × 0.65 ÷ 3,877mAh).
Why is my power bank providing fewer charges than expected?
Energy loss during charging, due to inefficiencies in the battery cells and circuitry, results in a 30% to 45% capacity reduction. Therefore, a fully charged Anker Zolo 10,000mAh Power Bank typically provides about 5,500mAh to 7,000mAh.
