WillItPlug

Check whether devices from one country will work in another, for questions like "do I need an adapter for Japan?" or "will my UK charger work in the US?". Use when both a home country and a destination are known; for one country alone use country_plugs. Takes an English country name or ISO code for each. Returns which plugs fit, whether an adapter is needed, whether a voltage converter may be needed, frequency differences, local notes, a packing checklist and a page url.

Look up the outlet and plug types, mains voltage and frequency of one country, for questions like "what sockets does Italy use?". Use when no home country is given; to compare two countries use check_trip. Takes an English country name or ISO code. Returns the types, voltage and frequency, regional notes for travellers and a page url.

Search for every country whose wall outlets are of one plug type, for questions like "which countries use Type G?" or "where else does my Type C plug work?". Use when the question starts from a plug type rather than a place; for one known country use country_plugs. Takes an IEC letter from A to O. Returns the matching countries with their voltage, frequency and page urls.

Describe one plug type itself: its standard, pin layout, whether it is earthed and which plugs its socket accepts, for questions like "what is a Type F plug?" or "does a Type C plug fit a Type F socket?". Not about any country: to list where a type is used call find_countries_by_outlet. Takes an IEC letter from A to O. Returns the plug and socket standards behind the letter.
