What it is

The TESSAN Universal Travel Adapter is a streamlined solution for globetrotters who need to power multiple devices across different continents. By integrating Type A, C, G, and I sliders, this single unit replaces a bag full of individual regional plugs. It allows you to connect up to five devices at once through a combination of one AC outlet and four USB ports. The inclusion of two USB-C ports is a modern touch, ensuring your newer smartphones and tablets charge without needing separate bulky bricks. Safety is a primary focus with this model, featuring a dual 10A fuse system and integrated security shutters to prevent accidental contact. Because it lacks surge protection and cords, it is fully compliant with cruise ship regulations, making it an excellent choice for maritime travelers. The compact cube design fits easily into a carry-on, though it is important to remember that this is a plug adapter only and does not convert voltage.

Ravvy AI insight

While the 20W total USB output is sufficient for overnight charging of multiple gadgets, it will not provide 'Fast Charging' for flagship phones if all ports are used simultaneously. Prioritize the USB-C ports for modern devices to get the best efficiency. Always verify that your high-power grooming tools are rated 100 to 250V before plugging them into the AC outlet to avoid permanent damage.
