Automatic fan regulation An intelligent fan system adjusts operation based on temperature needs to provide consistent cooling performance under varying conditions. Benefits: helps maintain safe operating temperatures, reduces risk of overheating, and supports stable performance. Dual interface current USB design with dual ports for broader application flexibility. When more power is needed, the ports can be connected in parallel to supply additional current. Benefits: enables charging or powering multiple devices simultaneously and scales power delivery as required. Efficient heat dissipation Upgraded components deliver higher fan speeds and heat management capabilities to safely accommodate greater charging demands. Benefits: faster heat removal, maintains safe operation under load, and supports higher charging performance. Protective temperature measures Smart regulation prevents overheating risks by effectively managing temperature during operation, increasing safety during use. Benefits: reduces thermal risk to devices and user, and provides reliable protection during prolonged use. Use scenarios Home or office desk: charge two devices at once (for example a laptop and a tablet or phone) with automatic cooling and safe operation. power charging: when one device requires additional current, connect ports in parallel to provide extra power while maintaining safe temperatures. Extended charging in warmer environments: heat management and protective regulation help prevent overheating during long charging sessions.
