What kind of power adapter do I need in Europe?

Figuring out how to power cameras and other gadgets in Europe can seem tricky, but it’s easy enough once you know how.

The trick is to look for a sticker on the power adaptor or plug that tells you the input voltage. The magic words to look for are something like this: “100-240V AC 50/60Hz”. 100-240 tells you the voltage range: Europe standardized on 220 volts for its standard household Power Supply. So the voltage range on your device needs to cover 220 volts or more for your electronics to work in Italy, France and most of Europe. If your gadget can cope with a higher range, that’s OK too (e.g. “90-240”).  In all of these cases, you just need a simple (and cheap) plug adapter and the device itself will automatically adapt to the higher voltage.

Devices that use more power, like hairdryers, coffee machines, portable kettles and anything else that produces a lot of heat, almost always only work on US 110 volts. Check the label: if it says something like “120VAC” or a smaller range such as “100-130V” then you cannot use it in Europe without a voltage Transformer. This is extremely important: if you plug a standard 120V hairdryer into 220V using a plug ac dc adapter, you risk melting or burning out the dryer. Many dryers have an overheating cut-out, but it’s better not to test it out . The good news is that there are travel hairdryers etc. available that are designed to adapt to the voltage.

In general it is much harder to design a high power device that is adaptable to 110V and 220V because to do so you need a very heavy and large voltage transformer which isn’t practical to build directly into the device.

External voltage transformers are available: they are rated by the amount of power they can supply, in Watts. So it might say on your electric kettle “1000W” — that means you need a 1000W or better transformer. Again, it can be dangerous to exceed the maximum rating of a transformer: the wiring will get very hot and it’ll likely blow a fuse. The worst-case scenario is that it melts and catches fire. The more power a transformer can supply, the larger and heavier it will be, so beware of smaller Power Supplies if you need a lot of power.
