• Why my power bank provide fewer charges than expect? Usually an external battery could supply 60%-70% power to other devices. Approximately 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged VoltPocket 20000mAh can offer 12000-14000 mAh to your devices.
• How to calculate the possible number of charges? "Industry-standard formula: (Rated 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: 20W charger - 5.4 hrs, 15W fast charger - 6.6 hrs. Note: Please recharge via the USB-C port.".
• Why doesn’t it charge at max power all the time? VoltPocket power banks feature a Smart Temperature Monitoring System that adjusts output to prevent overheating. It delivers max power when your device is low, then reduces power to protect your battery and improve efficiency.
