Travel adapters: choose the plug, power and protection you need

Choose a travel adapter by destination plug type, voltage compatibility, USB-C output, earthing and device load.

Start with the shape of the decision

A plug adapter changes the physical connection; it does not necessarily convert voltage. Check the destination and every appliance label before comparing port counts or charging claims.

  1. Confirm the plug type and mains voltage used at every destination.
  2. Read the input range printed on each charger or appliance.
  3. Leave high-power heating appliances at home unless both adapter and voltage support are explicit.
