• Why my power bank provide fewer charges than expect?
• Usually an external battery could supply 60%-70% power to other devices. About 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged INIU 20000mAh power bank can offer 12000-14000 mAh to your devices.
• How to calculate the possible number of charges?
• Industry-standard formula: (Power bank capacity × 65%) ÷ Device battery capacity ≈ Number of Charges.
• eg. (20,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 4.0 charges
• How long does it take to 100% recharge?
• It depends on the power of the wall charger used
• 27W charger - 3.9 hrs, 15W fast charger - 6.8 hrs.
• Note: Please recharge via the USB-C port.
