3MK Charger Hyper GaN 65W QC4+ — USB GaN 65W fast charger with QC4+ support

The 3MK Charger Hyper GaN 65W QC4+ is a compact USB power adapter that uses gallium nitride (GaN) technology to provide up to 65W of output in a small housing. Designed for modern portable devices, it supports the QC4+ fast-charging protocol for compatible phones and accessories while delivering sufficient power for many laptops, tablets and other electronics. Its compact size and efficient thermal performance make it practical for everyday use at home, in the office or while travelling.

Advantages

The GaN-based design enables a higher power density and smaller footprint compared with traditional silicon chargers, allowing 65W output from a compact adapter. Support for QC4+ ensures faster charging for compatible devices, and intelligent power delivery adjusts output to match device requirements. The charger’s efficient energy conversion reduces heat generation and improves charging stability during extended use.

How to use

Connect the 3MK Hyper GaN 65W QC4+ charger to a mains outlet using the appropriate plug or adapter for your region, then connect your device using a compatible USB-C cable. The charger negotiates the correct voltage and current with the connected device and supplies power according to the device’s requirements. For optimal performance, use a high-quality USB-C cable rated for the intended power level and ensure the device supports PD or QC4+ when fast charging is required.

Usage recommendations

Place the charger on a stable, well-ventilated surface during use, avoid covering the adapter while charging, and disconnect the charger from the mains when not in use. Use cables rated for the charger’s maximum power to maintain safe and efficient charging. If a device does not support QC4+ or PD negotiation, it will charge at a lower, standard rate.
