The four USB ports include two USB A and two USB C connections, delivering a combined 21W output. The USB A ports support up to 2.4A while the USB C ports reach up to 3A, providing fast and efficient charging for phones, tablets, laptops, cameras, earphones and other essential travel electronics. All USB ports intelligently detect connected devices to optimise charging performance.
Designed for convenience, the TESSAN Universal Travel Adapter 21W transforms four international plug types into one compact unit that powers up to five devices at the same time. This makes it ideal for use in airports, hotels, dorm rooms and other locations where outlets are limited. Its lightweight 149 g construction and compact 5 x 5.3 x 7.1 cm size allow it to fit easily into pockets, handbags, backpacks and carry-on luggage without adding unnecessary bulk. With no surge protection and no cords, it is fully compliant with cruise ship regulations.
Safety remains a core focus of the design. The adapter includes double 10A fuse protection with an additional spare fuse provided, along with integrated safety shutters to support secure operation during international travel. As with all universal adapters, it is not a voltage converter and is suitable only for devices that support 100V to 250V dual voltage. Travellers using high-power appliances such as hair dryers, straighteners or curling irons should ensure their devices are compatible before use.
The adapter is small and lightweight and easily fits into a bag without taking much room. This is a must have addition to your kit if you travel!
The TESSAN Universal Travel Adapter 21W is available now priced around £20.99.
