Slovakia Power Plugs, Wall Sockets & Electrical Outlets
In Slovakia, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded) and Type E (CEE 7/5, two round pins plus hole for socket grounding pin, 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 Slovakia.

Slovakia Travel Adapter Guide
The Slovakia power plug system relies on two standards: Type C and Type E. Travelers arriving from outside continental Europe will almost certainly need a travel adaptor to fit their devices into the local wall socket, since plug shapes and pin spacing differ from those used in North America, the UK, and much of Asia.
Slovakia uses the Type C Europlug and the Type E French-style grounded plug for its AC power plugs and sockets. Type C is a compact two-pin design used mainly for small, double-insulated electronics such as phone chargers, while Type E adds a grounding connection for larger household appliances and equipment that requires an earth connection.
- Type C (Europlug): two round 4mm pins, ungrounded, rated up to 2.5A, ideal for phones, tablets, and cameras.
- Type E: two round 4.8mm pins with a socket-side grounding pin, rated up to 16A, used for grounded appliances.
Voltage and Frequency in Slovakia
Slovakia operates on a 230V supply at 50Hz, matching the standard used throughout most of Europe. This is the same voltage and frequency found in neighboring countries such as Poland and the Czech Republic, so travelers moving between these countries won't need to worry about differing electrical standards.
Do You Need a Travel Adaptor for Slovakia?
Anyone traveling from a country that uses a different plug shape will need a travel adaptor to connect their devices to a Slovak wall socket. Since Slovakia uses both Type C and Type E, an adaptor that supports the Type E standard offers the broadest compatibility, as Europlugs can also fit into Type E sockets, though without a grounding connection.
Is a Voltage Converter Necessary?
A voltage converter is only necessary for travelers bringing devices designed for voltages significantly different from 230V, such as certain 110-120V appliances from North America. Most modern electronics, including phone chargers, laptop chargers, and camera equipment, are dual-voltage and can handle 220-240V automatically, meaning a simple plug adaptor is sufficient rather than a full converter.
Frequently Asked Questions
Yes, unless your home country already uses Type C or Type E plugs. Slovakia's sockets accept Type C Europlugs (ungrounded) and Type E plugs (grounded), so a travel adaptor matching one of these will let you use a standard wall socket.
Yes, phone chargers are typically dual-voltage and designed to work on 220-240V systems like Slovakia's 230V supply. You'll just need a plug adaptor to physically fit a Type C or Type E outlet, not a voltage converter.
Slovakia uses a 230V electrical supply at a frequency of 50Hz. This matches the standard voltage used across most of continental Europe.
Slovakia's Type E sockets are grounded, using a protruding pin in the socket that connects with a hole in the plug to provide 16A grounding protection. Type C Europlugs, however, are ungrounded and rely on double insulation instead.
