Frequently Asked Questions
- Q: Can it charge low-current devices like earphones?
A: 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: How long does it take to fully charge the power bank?
A: 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. - Q: Does it support charging while discharging?
A: 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?
A: 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?
A: 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 of usable power.
Important Notes
- A single USB-C port can deliver up to 30W; using multiple ports simultaneously reduces total output to 15W.
- For iPhone 14 series and earlier models, use your own Lightning cable connected via the USB-A or USB-C port.
- While pass-through charging is supported, it is not recommended for simultaneous charging of laptops.
- To estimate the number of charges for your device, use the formula: (10,000mAh × 0.65) ÷ device battery capacity. Actual results may vary due to energy loss from heat and circuit inefficiencies, typically resulting in 5,500–7,000mAh usable capacity.
- Package includes: Anker Zolo Power Bank (10K, 30W), built-in USB-C cable, 18-month warranty, and customer service support.
