Power adapters for Greece

You do not need a voltage converter for Greece, and almost nobody does any more. Greece runs 230 volts at 50 hertz on the round two-pin Europlug, and essentially every modern charger — phone, laptop, camera, tablet — is printed 100–240 V on its casing. Check the small print on the brick itself and you will nearly always find it. What you need is a plug adapter, which changes the shape of the pins and nothing else, not a converter, which changes the voltage and costs more, weighs more, and would only matter for something genuinely single-voltage.

One naming trap causes more confusion than the electricity does. The Greek wall socket is "Type C" — the round two-pin European standard — and that has nothing whatsoever to do with USB-C. Searching for a "Type C adapter" will return both, and they solve entirely different problems.

The better trick is to skip the adapter for your main charger altogether. Some multi-port hubs take a removable mains cord rather than a molded-on plug, and if yours does, you can replace that cord with a European figure-of-eight lead and put the charger straight into the Greek wall with no adapter in the chain at all. It is one less thing to lose behind a hotel headboard and one less point of failure. Two details matter when you buy the cord: it has to be the C7 figure-of-eight, not the C5 cloverleaf, and it has to be the non-polarized version, because the polarized one has a squared-off shoulder that will not seat.

Anything with a hardwired plug is stuck with an adapter, which matters when you are planning a whole family's charging setup, which is a real consideration when choosing what to bring rather than something to discover in the room. A high-wattage charger with a molded cord is not more travel-friendly for being powerful — it is one that has to go through a dongle.

Be careful with travel hubs that carry their own AC outlets. Those pass mains voltage through to whatever you plug into them, so the dual-voltage check applies again on the far side. Some units are labeled with a US voltage on the housing while the manufacturer's own support pages list them as 100–240 V, which is a certification artifact rather than a real limit — but that is worth confirming on the maker's site for your specific model before you rely on it abroad.
