Why doesn't my device always charge at the advertised maximum wattage?
Charging speed depends on your device, charging protocol, battery level, and temperature. The advertised wattage is the power bank's maximum output capability, while your device automatically adjusts the actual charging speed.
Why can't my phone reach its original 65W/80W/100W charging speed?
Some smartphones use proprietary fast-charging protocols. This power bank supports **USB PD 3.1, PPS, and QC**, and will automatically deliver the fastest compatible charging speed supported by your device.
Why isn't my laptop charging at 140W?
140W is the maximum output capability of the power bank. Actual charging power depends on your laptop's charging protocol, battery level, workload, and temperature.
Why does the power bank get warm during charging?
Heat is normal during high-power charging. The built-in temperature protection system continuously monitors the battery and may temporarily reduce charging power to ensure safe operation.
Why is charging slower when my phone battery is above 80%?
This is normal. Most smartphones automatically reduce charging speed at higher battery levels to protect battery health and extend battery lifespan.
