Important Notes
Actual charging capacity may vary due to energy loss during conversion, typically resulting in 11,000–14,000mAh of usable power (approximately 65–70% efficiency). To estimate charges for your device, use the formula: (20,000 × 0.65) ÷ device battery capacity. Avoid charging your phone while simultaneously recharging the power bank to preserve battery longevity. The power bank does not support simultaneous charging and discharging for laptops. Package includes the Anker Zolo Power Bank, built-in USB-C cable, welcome guide, 18-month warranty, and access to Anker’s customer support. For optimal charging speed, use a 20W or higher USB-C charger (not included).
