Power adapter SWISSTEN GaN Mini Travel Charger 30W with USB-C and USB ports

SWISSTEN GaN Mini Travel Charger 30W is a compact power adapter designed to charge phones, tablets and other portable devices. Using GaN (gallium nitride) technology, the charger achieves high efficiency and smaller dimensions while delivering up to 30W total output. It includes one USB-C port with Power Delivery and one USB-A port with Qualcomm fast charge compatibility, allowing single-device fast charging or modest simultaneous charging of two devices when needed.

Advantages

GaN technology enables higher efficiency and reduced heat generation compared with conventional silicon-based chargers, which allows the adapter to be much smaller while keeping stable power delivery. The miniature footprint makes the charger easy to carry in a pocket or travel bag. Power Delivery on the USB-C port supports modern iOS and Android fast-charging profiles, while the USB-A port with Qualcomm compatibility supports older devices. The charger accepts standard 200–240V AC input and provides safe, consistent output up to a maximum of 30W.

Suitable for

• Charging modern smartphones and small tablets via USB-C Power Delivery
• Charging older Android phones and accessories via USB-A (Qualcomm fast charge)
• Travel use where compact size and low weight are important
• Simultaneous charging of two small devices at reduced combined output

Key specifications

• Maximum total power output: 30W
• Input: 200V–240V AC, 0.85A, 50Hz–60Hz
• USB-C output (Power Delivery): 5V ⎓ 3A, 9V ⎓ 3A, 12V ⎓ 2.5A
• USB-A output (Qualcomm compatible): 5V ⎓ 3A, 9V ⎓ 3A, 12V ⎓ 2.25A
• Both ports used simultaneously: combined 5V ⎓ 3A
• GaN (gallium nitride) semiconductor technology for reduced size and heat
• Compact physical dimensions (approx. 3 x 3 x 3 cm without plug)

How to use

Plug the charger into a compatible 200–240V AC mains outlet. Connect your device to the USB-C port to take advantage of Power Delivery fast charging or to the USB-A port for Qualcomm-compatible fast charging. When charging two devices at once, expect reduced combined output; the charger will supply a combined 5V ⎓ 3A across both ports. Ensure the charging cable and the connected device support the appropriate fast-charge profile for optimal performance. Do not cover the charger during operation to allow heat dissipation.

Usage recommendations

Use high-quality, certified USB-C and USB-A cables and verify device compatibility with Power Delivery or Qualcomm charging profiles. Avoid using the charger in excessively humid or dusty environments and unplug it when not in use. For continuous high-power charging, periodically check that the charger and connected devices remain cool to the touch.
