Do you need a travel adapter for Saint Helena?
It depends on where your plugs come from.
🇺🇸 From the United States
You need a plug adapter. Plugs from the United States (Type A and B) don't fit the Type G sockets in Saint Helena. A Type G (UK 3-pin) adapter fits the listed socket families there. Socket variants can differ; check the actual outlet and adapter rating.
Saint Helena uses 240 V, much higher than the 120 V in the United States. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter. For single-voltage devices, follow the manufacturer's guidance on conversion; using a suitable local device may be simpler.

Will your devices work in Saint Helena?
Sockets in Saint Helena supply 240 V. Find the "input" line on each device or its charger. An input rating of "100–240V" covers the listed supply voltage; you still need a suitable plug or adapter.

Check the label first: electric toothbrush, electric shaver, CPAP machine, hair straightener / curler.
Usually single voltage: hair dryer, kettle / coffee maker, anything with a heating element.
