Approximately 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged INIU 20000mAh can offer 12000-14000 mAh to your devices. **Q: How to calculate the possible number of charges?** A: "Industry-standard formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges. eg. (20,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 4.0 charges" **Q: How long does it take to 100% recharge?** A: "It depends on the power of the wall charger used 20W charger - 5.4 hrs, 15W fast charger - 6.6 hrs. Note: Please recharge via the USB-C port." **Q: Why doesn’t it charge at max power all the time?** A: INIU power banks feature a Smart Temperature Monitoring System that adjusts output to prevent overheating.
