Do travel adapters convert voltage?

No. Almost every product in this category, including the EPICKA, Anker, and TESSAN units here, explicitly states it is 'not a voltage converter.' These devices only reshape the plug so it fits a foreign socket. Modern electronics (phones, laptops, camera chargers) are typically dual-voltage 100-240V and are fine, but high-wattage heating appliances like hair dryers and curling irons can be damaged or pose a fire risk. Always check the appliance's input rating before plugging in.
