20000mAh portable charger for heated gear

The WOOJONG power bank supplies 20000mAh capacity with 22.5W fast charging via USB-C input and output. It targets outdoor workers and campers who need extended runtime for heated clothing, blankets or seat pads. The integrated LED display shows remaining charge at a glance.

Plug-in power with PD 3.0 and QC 4.0

Simply connect a compatible cable to the USB-C port and the bank negotiates the optimal voltage automatically. No driver installation or configuration is required. The main limitation is that devices without USB-C PD or Quick Charge support will fall back to standard 5V charging speeds.

Steady output during long heating sessions

The 22.5W rating is sustained rather than a brief peak, so heated apparel receives continuous power through a full work shift or overnight trip. Voltage regulation protects both the power bank cells and the connected garment from wear caused by prolonged high-current draw.
