SWISSTEN Travel Charger GaN 70W 2×USB-C fast charger for laptops and phones

Compact SWISSTEN Travel Charger GaN 70W with two USB-C ports and one USB-A port delivers up to 70W total output for charging laptops, tablets and smartphones. Based on GaN (gallium nitride) semiconductor technology, the charger achieves higher efficiency and reduced heat generation, which allows a smaller form factor while providing stable fast charging with Power Delivery (including PDO and PPS formats).

Advantages

GaN technology enables higher efficiency and lower heat compared with silicon-based chargers, allowing a more compact design without sacrificing power. Two USB-C outputs support Power Delivery fast charging (including PDO and PPS) for compatible Apple and Samsung phones as well as many laptops and tablets, while an additional 5W USB-A port powers smaller devices. Intelligent power distribution optimizes output when multiple devices are connected, providing up to 65W combined across the two USB-C ports.

Suitable for

• Charging laptops and ultrabooks that accept USB-C PD input
• Fast charging smartphones (Power Delivery / PPS and compatible Super Fast Charging)
• Powering tablets and large-screen devices while travelling
• Charging smaller accessories via the 5W USB-A port

Key specifications

• Input: AC 100–240 V, max 2 A
• USB-C output (single-port): up to 65 W — 5 V/3 A, 9 V/3 A, 12 V/3 A, 15 V/3 A, 20 V/3.25 A
• USB-A output: DC 5 V / 1 A (max 5 W)
• Total maximum output: 70 W; when two devices use USB-C ports, combined USB-C output up to 65 W (power distribution optimised)
• Supported fast-charge protocols: Power Delivery (PDO) and Power Delivery PPS

How to use

Plug the charger into a compatible AC mains outlet (AC 100–240 V). Connect devices using USB-C to USB-C cables for laptops, tablets or smartphones to benefit from Power Delivery fast charging; use the USB-A port for smaller accessories. When two devices are connected to the USB-C ports, the charger automatically adjusts power distribution to provide optimal charging up to a combined 65 W for the two ports.

Recommendations

Use high-quality USB-C cables rated for the required wattage to ensure safe and efficient charging. To preserve battery health, prefer PPS-compatible charging for devices that support it. Avoid using the charger in extremely hot or humid environments and unplug when not in use.
