HuntKey has released the S67 mini, a compact 67W wall charger equipped with 3 USB ports. Built with gallium nitride hardware, the two prong brick delivers high wattage charging while maintaining a pocket sized footprint. The unit is currently available in China for 109 yuan.
The internal circuitry runs on a flyback topology with a buck step down configuration. To manage thermal output during high load situations, HuntKey integrated graphene material with potting compound inside the casing. This structure spreads heat evenly across the exterior shell. The charger carries official CCC certification and is rated for safe operation at altitudes up to 5000 meters. Built in safety protections guard against over voltage, over current, over temperature, short circuits, electrical surges, static discharge, and fire hazards.
Port options consist of 2 USB C ports and 1 USB A port. Plugged in by itself, either USB C port outputs the full 67W capacity, providing enough power for lightweight laptops and mobile devices. The single USB A port delivers up to 33W when used alone. Power distributes automatically depending on how many cables are plugged in at the same time.
Connecting 2 devices allows the primary USB C port to supply 45W while the secondary connection receives 20W. If both secondary ports are used together without the primary, power splits evenly at 15W for each connector. When all 3 ports are active at once, the primary USB C port retains a dedicated 45W flow, while the remaining 15W is shared between the other USB C and USB A outputs.
