Universal Travel Adapter

The TESSAN TS-WTA10 combines four USB ports with a sliding plug system that fits outlets in over 150 countries. It delivers up to 20 W total across two USB-C ports rated at 15 W each and two USB-A ports rated at 12 W each. The unit weighs 155 grams and measures 5.0 in x 5.46 in x 6.42 in, making it a compact companion for international trips. It is not a voltage converter, so connected devices must support 100 V to 250 V operation.

Thermals and Power Draw

In normal use the adapter runs cool because it contains no internal fan or active cooling; heat dissipates through the plastic housing during typical phone or tablet charging. The dual 10 A fuses protect the AC outlet rated at 2500 W maximum without adding audible noise. Standby consumption is negligible when no devices are attached. The compact 2.53 x 2.15 x 1.97 in form factor leaves ample airflow around the body.

Sustained Load Behaviour

When all four USB ports draw their maximum 20 W combined output continuously, the housing warms noticeably but remains within safe limits thanks to the integrated fuse protection. The AC outlet can sustain 2500 W for high-draw appliances such as dual-voltage hair tools, provided the devices themselves accept the local voltage. No surge protection is included, so the unit relies on the fuses and safety shutters for fault isolation during extended sessions.

Questions about this item

How do I extend the plug pins on the TS-WTA10 and make sure they lock?

Long-press the side button and slide the pins all the way out until you hear a pop; the pop confirms the pins are locked in place.

Do the 10 A fuses on the TS-WTA10 need routine replacement?

The dual 10 A fuses only need changing if one blows from an overload; there is no scheduled replacement interval.

What is the combined USB power ceiling that limits sustained charging on the TS-WTA10?

All four USB ports share a 20 W maximum, so total output drops when multiple devices draw power simultaneously.
