A new universal travel adapter is entering an already crowded market, as TESSAN introduces its Universal Travel Adapter 21W, now available through Amazon and the company’s own website. Positioned as a compact 5-in-1 charging solution, the device is designed to support travellers who need to power multiple devices across different plug standards without carrying several adapters.
The TESSAN Universal Travel Adapter 21W combines a universal AC outlet with four USB ports — two USB-C and two USB-A — allowing up to five devices to be connected at once. The USB output is capped at a combined 21W. According to the specifications, the USB-A ports deliver up to 5V/2.4A (12W total), while the USB-C ports reach up to 5V/3A (15W), with intelligent charging that detects connected devices to adjust output accordingly. In practical terms, this setup is aimed at smartphones, tablets, cameras, earphones and other everyday electronics rather than high-draw equipment.
The universal AC socket is compatible with plug types C, G, A and I, covering more than 224 countries and regions, including much of Europe, the United Kingdom, North America, Australia and parts of Asia. As with most universal adapters, it is important to note that this product is not a voltage converter. It supports devices rated for 100V to 250V dual voltage only. High-wattage appliances such as hair dryers or straighteners must be checked carefully for compatibility before use.
In terms of size and portability, the adapter measures 5 x 5.3 x 7.1 cm and weighs 149 grams. The compact, all-in-one format is intended to reduce the need for separate plug heads or multi-port chargers, which can be particularly useful in hotel rooms, airports, dormitories or cruise cabins where outlets are limited. The absence of surge protection and cords makes it compliant with many cruise ship regulations, a detail that frequent cruise travellers often have to consider when packing electronics.
Safety features include double 10A fuse protection, integrated safety shutters and a spare fuse included in the box. The rated power is 110V at 1100W and 250V at 2500W, aligning with typical travel adapter standards in this category.
The TESSAN Universal Travel Adapter 21W is priced at $21.99 in the United States and is currently offered at £16.99 in the UK (RRP £21.24). At this price point, it sits within the mid-range segment of the universal travel adapter market, competing with other compact multi-port solutions aimed at frequent flyers and international travellers.
For consumers evaluating travel charging gear in 2026, the appeal of a universal travel adapter 21W model lies in consolidation: fewer cables, fewer bricks and broader compatibility. Whether it replaces separate chargers will depend largely on individual power needs and the mix of devices being carried.
