Power adapter TECHLY GaN USB-C 20W PD and USB-A 18W QC charger

TECHLY GaN USB-C 20W PD and USB-A 18W QC charger is a compact mains power adapter designed for fast charging of smartphones, tablets and other portable devices. The charger integrates Gallium Nitride (GaN) technology to reduce size and heat generation while delivering stable output through a USB-C Power Delivery port (20W) and a USB-A Quick Charge-compatible port (18W). It comes with a standard mains plug and built-in power management that optimizes charging for single-device or dual-device use.

Advantages

The GaN design enables a smaller footprint and improved thermal efficiency compared with conventional silicon chargers, making the adapter more portable and less prone to overheating during extended use. Two output options—USB-C PD and USB-A QC—provide compatibility with a wide range of devices and charging cables. Intelligent power management helps prevent overcurrent and overvoltage, and prioritizes safe, efficient power delivery to connected devices.

Suitable for

• Fast charging smartphones and phablets using USB-C PD or USB-A QC
• Charging tablets and small portable gaming devices
• Travel and commuting due to compact GaN form factor
• Desktop or bedside charging where space and thermal control are important

How to use

Insert the mains plug of the adapter into a compatible wall outlet. Connect the device to be charged using a USB-C to device cable for Power Delivery or a USB-A to device cable for Quick Charge. When charging two devices simultaneously, ensure each cable is fully seated; the adapter will distribute available power between ports according to device requirements. Disconnect the adapter from the mains when not in use.

Usage recommendations

Use certified cables and device connectors that support the required charging standard (PD or QC). Avoid using the adapter in damp environments or where ventilation is restricted. For best results, connect high-power devices to the USB-C PD port. Regularly inspect the adapter and cables for damage and replace them if wear is observed.
