Dual port fast charging at the same time: a PD 3.0 port up to 30W and a QC 3.0 port up to 18W, delivering efficiency for two devices simultaneously. Realtime monitoring and energy saving: built in voltmeter and independent energy saving features enable real time battery voltage detection, power preservation, and automatic output adjustment to optimize energy use. Safe and protective design: fully sealed, flame retardant cover with overload protection and short circuit protection to enhance safety during use. Durable construction for harsh conditions: made from sturdy ABS material, designed to endure extreme temperatures for long term reliability. Compatibility and usage: supports devices that use PD 3.0 and QC 3.0 charging standards, suitable for smartphones, tablets, and other compatible devices. Use scenarios: At home or in the office, charge two devices simultaneously with optimized power delivery for faster, efficient charging. While traveling, enjoy efficient charging with energysaving features that help preserve battery health. In environments with temperature variation (garage, workshop), the flame retardant cover and ABS housing provide reliable, durable performance.
