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 10000mAh power bank can offer 6000-7000 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. (10,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 2.0 charges"

Why doesn’t it reach 45W when used as a wall charger?

Because this product can reach up to 30W when used as a wall charger, but it can reach 45W only when used as a power bank

Does it support pass-through charging?

Yes, our power bank supports pass-through charging. You can charge both the power bank and connected devices simultaneously.

Why doesn’t it charge at max power all the time?

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.
