Intelligent Fan Control: An optimized fan drive circuit automatically starts and stops to maintain stable airflow and operate efficiently over a wider working voltage range. Dual USB Interface: current USB ports with dual interfaces increase versatility and can be used in parallel to meet higher power needs. Upgraded Heat Dissipation: Enhanced power tube design increases fan speed and improves heat dissipation, enabling higher charging power for demanding applications. Over Temperature: Smart temperature regulation prevents overheating, protecting the module from damage during overload conditions. Practical applications Use in a home or office multidevice charging setup where stable cooling and a wide voltage range support reliable operation. Use in parallel USB configurations to deliver higher power for demanding devices that require more current. Use in environments with potential heat buildup, such as workshops or labs, to safeguard the module and connected equipment during overload events.
