In the lessons

In everyday life travellers need a travel adaptor because plugs are different in the UK, Ireland, the USA, Australia and Europe. Phone chargers and computers use adaptors. In safety lessons: do not plug too many things into one adaptor, because it can overheat and start a fire. Phrases: travel adaptor, plug adaptor, power adaptor.

Note

Countable noun. Both spellings are correct: «adaptor» is more common in British English for the device, «adapter» in American English. Comes from «adapt» (to change to fit). Safety: an overloaded adaptor can overheat — never plug adaptors into adaptors.
