Bulgaria Power Plugs, Wall Sockets & Electrical Outlets
In Bulgaria, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded) and Type F (CEE 7/4 (Schuko), two round pins with grounding clips on sides, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Bulgaria.

Do You Need a Travel Adaptor for Bulgaria?
If you're travelling to Bulgaria with electronics from outside continental Europe, you will likely need a travel adaptor. A Bulgaria power plug adaptor allows devices built for other regions' AC power plugs and sockets to physically fit into Bulgarian wall outlets, since Bulgaria uses the two-pin round plug styles common across most of Europe rather than flat-pin or rectangular-pin designs found in the UK, North America, or Australia.
Voltage and Frequency in Bulgaria
Bulgaria runs on a 230V, 50Hz electrical supply, matching the standard used throughout Europe. Travellers from countries with 220-240V systems generally won't need a voltage converter, but visitors from regions using 100-127V, such as the United States, Canada, or parts of Japan, should check whether their devices are dual-voltage before plugging in, since a plug adaptor alone will not adjust the voltage.
Power Sockets and Plug Types in Bulgaria
Bulgaria primarily uses two plug and socket-outlet standards: Type C and Type F. Type C, also known as the Europlug, is a compact two-pin design rated for low-power electronics, while Type F, the Schuko plug, is a robust grounded connector built for higher-power appliances. Most modern Bulgarian sockets are designed to accept both plug types.
Grounding and the Earth Pin
Type F sockets in Bulgaria provide grounding through side contact clips rather than a central grounding pin, offering protection for appliances like washing machines, ovens, and power tools. Type C Europlugs, by contrast, have no grounding pin at all and are intended only for double-insulated, low-power devices such as phone chargers and small electronics.
- Type C (Europlug): Two round 4mm pins, 19mm long, spaced 18.6mm apart; ungrounded; rated up to 2.5A at 220-240V; ideal for phones, cameras, and small electronics.
- Type F (Schuko): Two round 4.8mm pins, 19mm long, with side grounding clips; grounded; rated up to 16A at 220-240V; suited to high-power appliances and offers a recessed, splash-resistant socket design.
Frequently Asked Questions
You'll need a travel adapter only if your home country uses a different plug shape than Bulgaria's Type C or Type F sockets. Since Bulgaria's sockets accept both round two-pin plug styles, most European travellers won't need one, but visitors from the UK, US, or Australia will.
Bulgaria uses Type C (Europlug) and Type F (Schuko) plugs. Type C is a two-pin ungrounded plug for low-power devices, while Type F is a grounded two-pin plug rated for 16A, suitable for high-power appliances.
Sockets designed for Type F plugs in Bulgaria are grounded, using side grounding clips rather than a grounding pin to protect appliances. Sockets used only with Type C Europlugs are ungrounded, since that plug is designed for double-insulated, low-power devices.
Yes, phone chargers are almost always dual-voltage and can handle Bulgaria's 230V, 50Hz supply without a converter. You'll simply need a plug that fits Bulgaria's Type C or Type F sockets if your charger's plug doesn't already match.
