Power Bank (20K, 30W, Built-in USB-C Cable) B2C - UN Black Iteration 1

Power Bank (20K, 30W, Built-in USB-C Cable) B2C - UN Black Iteration 1

Q: Is it normal for the charging speed to be slow?

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 5.1 hours.

Q: 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!

Q: 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.

Q: 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).

Q: 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 20,000mAh Power Bank typically provides about 11,000mAh to 14,000mAh.
