Electricity and sockets
Yes – from the UK you need a travel adapter for Bulgaria, because the sockets there (Types C and F) will not take your plugs.
Sockets at the destination
Sockets in Bulgaria: Types C and F, supplied with 230 V at 50 Hz. 230 V means no voltage converter – only the plug shape matters.
The same socket system is used in Moldova, Slovenia, Kosovo and Estonia, so one adapter covers all of them. Travelling further to Cyprus, the Isle of Man and the United Kingdom means a different adapter. In Europe, 31 of 50 recorded destinations use exactly this combination.
Protective earth
Bulgaria has sockets with a protective earth (Type F) and without (Type C). A plug that fits mechanically does not guarantee earthing.
