How can I estimate the number of times my device will be charged?
To estimate charging cycles, use these formula:
(Power Bank Capacity × 0.5) ÷ Device Battery Capacity ≈ Number of Charges.
For instance, charging a 3,200mAh device using a 5,000mAh Wireless power bank would offer approximately 0.78 charges.

Why does my phone generate heat while charging？
The charging temperature should be kept below 104 ° F (40 ° C), but using the phone during charging will generate heat. If the temperature is too high, please stop charging and let the phone cool down before continuing.
-
Why does charging stop at 80%?
As part of the iOS 17 hot management strategy, your iPhone may automatically stop charging at 80% to prevent battery overheating. After the device cools down, charging will resume. Moving it to a colder place can help speed up this process.
-
Why does my phone display the prompt message ''Slow Charger''?
To manage heat, if the device heats up, it may reduce power. On iOS 18, there may be a "slow charging" alert, but charging is still safe and effective.
-
Why is the actual charging capacity of the power bank less than expected?
The decrease in capacity during charging is due to 30% to 45% energy loss in the battery unit and conversion circuit. Therefore, a fully charged battery is estimated to supply 2750mAh~3250mAh of power to the device.
