SWISSTEN Edge GaN Travel Charger — GaN USB-C PD 20W + USB-A 18W QC

The Swissten Edge GaN travel charger is a compact dual-port wall charger designed for everyday use at home and on the go. It combines a USB-C Power Delivery port with a USB-A Quick Charge port to charge two devices simultaneously. Gallium Nitride (GaN) components allow a smaller, more efficient design with reduced heat generation compared with traditional chargers, making this charger a practical option for travel and daily carry.

Advantages

Small size and low weight make the charger easy to carry in a bag or pocket. The USB-C port delivers up to 20W with Power Delivery support for fast charging of modern smartphones and other PD-compatible devices, while the USB-A port provides up to 18W with Quick Charge compatibility for a wide range of accessories. Built-in protections guard against over-current, overheating and short circuits.

Suitable for

• Charging smartphones with USB-C PD support
• Powering accessories such as wireless earbuds, power banks, and Bluetooth devices via USB-A
• Travel and daily commuting where a compact, lightweight charger is preferred

When it may not be suitable

This charger provides modest combined output when both ports are used simultaneously, with a shared maximum of 15W at 5V. It is not intended to power high-wattage devices such as laptops that require more than 20W from a single port.

Key specifications

• Dimensions: 42 x 41 x 29 mm
• Weight: 47 g
• Input: 200–240 V AC, 0.6 A, 50/60 Hz
• USB-C output (PD): 5 V 3 A, 9 V 2.22 A, 12 V 1.67 A — up to 20 W
• USB-A output (QC): 5 V 3 A, 9 V 2.0 A, 12 V 1.5 A — up to 18 W
• Both ports combined: 5 V 3 A — up to 15 W
• Safety features: over-current, over-temperature and short-circuit protection

How to use

Plug the charger into a compatible wall outlet (200–240 V). Connect a USB-C cable to the USB-C PD port to charge PD-compatible devices at up to 20W, or use the USB-A port with a suitable cable for Quick Charge-capable accessories. When charging two devices simultaneously, the charger will share available power between ports according to device requirements. Ensure cables are fully inserted and monitor device temperatures during initial use.

What to consider before purchase

• Combined output is reduced when both ports are used simultaneously (max. 15W at 5V).
• Not suitable for charging laptops or other devices that require higher single-port wattage above 20W.
• Verify your device supports PD or QC to benefit from fast charging speeds.

Usage recommendations

Use certified cables and connect one high-power device at a time for optimal fast-charging performance. Allow the charger adequate ventilation during extended use and avoid covering it to prevent heat build-up.
