230 V · 50 Hz on Type G.

One socket rules everything: the big three-rectangular-pin Type G, with a fuse inside every plug and shutters over every outlet, delivering 230 V at 50 Hz. Nothing else fits without an adapter — europlugs included — so every visitor needs one. North Americans should also make sure their devices are dual-voltage.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.
