The charger is intended to consolidate charging for smartphones, tablets, small laptops and accessories in home, office or travel environments.

Advantages

The GaN-based design reduces size and heat compared with traditional silicon chargers while maintaining efficient power delivery. Ten available ports enable simultaneous charging of many devices without the need for several separate adapters. Per-port power of up to 20W supports fast charging profiles for compatible smartphones and accessories. The mix of USB-C and USB-A outputs ensures compatibility with current and legacy charging cables and devices.

How to use

Plug the charger into a compatible mains outlet, connect devices using appropriate USB-C or USB-A cables, and allow the charger to negotiate charging with each device. For best results, use cables rated for the intended power level and connect higher-priority devices to ports known to support the required output. Monitor device temperature during initial use; the GaN design reduces heat but connected devices may still warm under load.

Usage recommendations

Use this charger on a stable, well-ventilated surface and avoid covering it while multiple devices charge. Ensure connected devices and cables support fast-charging profiles if you need the full 20W per port. When traveling, verify local mains voltage compatibility and use appropriate adapters where necessary.
