Travel plug & voltage finder

Choose your home country and your destination to see which plugs the sockets take, what the voltage is, and whether your chargers need an adapter, a converter, or nothing at all.

Data after the IEC World Plugs reference, checked 2026-10-02. Hotels sometimes fit international sockets, but do not count on it.

Adapter, converter, or neither

Look at the small print on your charger. If it says INPUT: 100-240V, it is dual-voltage and works in every country on earth: all it needs is the right shape of plug, which a cheap adapter provides. Almost every phone, laptop, tablet and camera charger made in the last fifteen years is like this.

The things that are not are usually heating appliances: hair dryers, curling irons and straighteners, travel kettles. If one of those says a single voltage such as 120V and your destination runs at 230V, leave it at home or buy a dual-voltage travel version. Converters for high-wattage heaters are heavy, expensive and still risky.

Packing tip: one adapter, not five

A single adapter with two or three USB ports, plus a short multi-socket extension from home, charges everything from one wall socket. That is lighter than an adapter per device and solves the hotel room with one socket behind the bed. If you travel to several regions, a universal adapter that takes A, C, G and I covers most of the world.

Common questions

Do I need an adapter or a converter?
An adapter only changes the shape of the plug. A converter changes the voltage. Phone, tablet, laptop and camera chargers almost always say 100-240V on the label, which means they work anywhere and only ever need an adapter. A converter matters only for single-voltage appliances such as some hair dryers, straighteners and electric toothbrush bases.
Is it safe to plug a 230V appliance into a 120V socket?
It will not be damaged, but it will run weakly or not at all. The dangerous direction is the other way: a 120V-only appliance plugged into 230V can overheat or burn out within seconds. Check the label for the input voltage before plugging anything in abroad.
Does the frequency (50 Hz or 60 Hz) matter?
Not for chargers or anything with a modern power supply. It can affect appliances with motors or clocks, which may run slightly fast or slow, but for a typical traveller it makes no practical difference.
Do all European countries use the same plug?
Most of the EU uses round-pin plugs (types C, E and F), and a two-pin Europlug (type C) fits nearly all of them. The exceptions are the UK, Ireland, Malta and Cyprus, which use type G, and Switzerland and Italy, whose own sockets (J and L) take a Europlug but not every three-pin plug.
