Power outlets when you travel
There is no single worldwide plug or voltage. You will most often see ~230 V / 50 Hz across Europe (with different socket shapes, especially in the UK) and ~100–127 V / 60 Hz in the US, Canada, and parts of Japan. Before you pack, check not only which adapter to buy, but whether your device accepts the local voltage — otherwise a plug adapter alone is not enough.
Types A–N — what does it mean?
Type labels (C, E, G, I, …) describe pin layout and matching sockets. Many countries officially list several types; hotels sometimes install “universal” or mixed outlets. Our tool lists types present in the dataset for that country — a starting point, not a guarantee for every wall socket.
Adapter vs transformer
An adapter only changes mechanical fit. A voltage transformer / converter is required when your appliance cannot run on the destination voltage (e.g. a “230 V only” hair dryer in the US). Most phone and laptop chargers today say 100–240 V — then you usually only need the right plug adapter, assuming stable mains power.
What might not work?
- Heating appliances (hair dryer, straightener, kettle) without multi-voltage support.
- Earthed devices (third pin) — cheap universal adapters may not preserve grounding safely.
- 50 Hz vs 60 Hz — usually irrelevant for electronics; occasionally relevant for some motor-driven clocks.
