Electricity in Bulgaria: Plugs, Adapters and Charging on Your Trip
Bulgaria generally uses Type F outlets with C or F plugs, on a 230V, 50Hz supply. Many continental European devices fit directly; equipment from other regions may need an adapter. Plug shape and voltage compatibility are separate checks.
Type F sockets and Type C plugs
Type F is a round recessed outlet with two openings and side earth contacts. The slim two-round-pin Type C Europlug used by many small chargers generally fits it.
The photographs distinguish slim plugs from thicker and earthed connectors. Check the actual device rather than choosing an adapter solely because its packaging says Europe.
Choosing the connection
A compatible C or F plug usually needs no adapter. British G, North American A/B and Israeli H plugs require suitable conversion of shape.
For equipment requiring earth, the adapter must preserve it. A two-pin-only adapter does not safely remove an appliance’s earthing requirement.

230V at 50Hz
A charger marked INPUT 100–240V, 50/60Hz supports the local supply and normally needs only any necessary physical adapter.
Inspect every appliance, including items bought abroad. OUTPUT describes what a charger sends to the device, not the acceptable mains supply.
When an adapter is not enough
An appliance marked only 110/120V is not suitable for direct connection, even through an adapter that fits. It needs a manufacturer-approved solution appropriate to its power and operation.
For hairdryers, kettles and other heating appliances, locally supplied equipment is often simpler. Do not rely on a small low-power converter.
Room charging
Confirm that charging has actually started. A room card or wall switch may control the outlet, and built-in USB does not guarantee laptop power or fast charging.
Avoid loose connections, high-power loads through unsuitable adapters and chains of extensions. Stop using a connection with unusual heat, smell or visible damage and contact the property.
Outage information in western Bulgaria
ERM Zapad’s western network has an electricity-interruption checking service, useful around Sofia and Blagoevgrad when establishing whether a problem extends beyond the property.
It is not a nationwide service. On the coast or elsewhere, ask which operator serves the address. If only the room is affected, contact accommodation staff first rather than opening electrical panels.
Mountain and rural stays
For a remote stay, ask about continuity of supply, available outlets and backup arrangements. A mountain hut need not have bedside sockets like a city hotel.
A charged power bank and small torch are useful after a day of photography and navigation. Keep the address, travel documents and host’s number available offline.
Medical equipment and EVs
Equipment requiring uninterrupted power needs advance discussion with both manufacturer and accommodation about supply, earth and backup. A general promise of electricity is insufficient.
An EV needs authorised suitable charging equipment. Type 2 and CCS vehicle connectors are separate from the small travel adapter used for a phone, so plan vehicle charging independently.
