The standard power supply in Tobago is 110v 60Hz with Type B (American 3-pin) plugs and sockets, as illustrated to the right. This type of socket also takes the standard two-pin-flat Type A (unearthed/ungrounded) plugs.
North American visitors will have no need for electrical adapters and can ignore the rest of this article. British and European travellers should assume that they will need a standard international plug adapter if they intend to take any electrical accessories to Tobago.
240volt 60Hz power is also available on Tobago. However, we know of very few properties that have dual-system electrics. Nevertheless, UK visitors may wish to contact the owner/manager of their hotel or rental villa to see if UK-friendly power sockets are available.
Even if 240v power is not available, UK visitors will be able to use most electrical accessories. Hairdryers and travel kettles should work - but they will not get quite as hot as usual and/or take a lot longer to get there. Visitors with 110v accessories must not, under any circumstances, use such items on the 240v 3-pin plug connection without an appropriate transformer.
It is important to check all devices that you intend to take on holiday, including laptops, tablets and smartphones. If the charger/device states something like "100-240V, 50/60 Hz' it will work perfectly in Tobago, as anywhere else in the world.
