Plug Sockets Worldwide: Which Adapter You Really Need

Nothing is more deflating than a hotel room at midnight, a dead phone — and a socket that nothing fits into. Yet the world’s socket chaos is quickly explained. Here is everything you need to know before your next trip abroad.

The most important plug types at a glance

• Type C/F (“Schuko”): Germany, almost all of Europe, Turkey — your default case.
• Type G: the UK, Ireland, Dubai, Singapore, Hong Kong — the three chunky pins. Nothing works here without an adapter.
• Type A/B: the USA, Canada, Mexico, Japan — flat parallel pins.
• Type I: Australia, New Zealand, China — angled flat pins.
• Special cases: Switzerland (Type J) and Italy (Type L) catch out even seasoned European travellers — a Schuko plug does not fit everywhere there.

Volts and hertz: will my device break?

The USA and Japan use 100–120 V instead of our 230 V. The good news: almost all modern chargers are dual-voltage (marked “100–240 V”) — phones, laptops, cameras and electric toothbrushes charge anywhere without trouble. Only heating appliances need caution: a hairdryer or straightener without a voltage switch does not belong in your suitcase for the USA. And note that an adapter converts no voltage at all — it only bridges the plug shapes.

Why a universal GaN adapter replaces your charger

The classic solution — a pouch full of individual adapters plus three chargers — is weight without benefit. The modern solution is a single device:

• The Altair travel adapter 65 W covers the sockets of over 150 countries — UK, USA, Australia and Europe in one housing.
• Thanks to GaN technology and 65 W, it charges not just your phone but a MacBook at full speed — the laptop power brick can stay at home.
• One port instead of three power bricks: the 65 W USB-C port serves a laptop, phone or power bank — and occupies only a single socket at the hotel.

Three practical tips from frequent travellers

• The adapter lives in your luggage: after a trip it stays in the suitcase or backpack — so it is guaranteed to be with you next time (more on that in our 20-minute packing method).
• Power bank in your carry-on: lithium batteries must never go in the hold — and on the plane itself you charge from the USB port in the console.
• One cable for everything: switch consistently to USB-C (phone, laptop, headphones) and you travel with a single cable type.

Quick check before departure

• ✔ Checked the plug type of your destination country?
• ✔ Verified your chargers say “100–240 V”?
• ✔ Universal adapter packed — in your carry-on, not the checked bag?
• ✔ Hairdryer and straightener left at home (the hotel has one)?

With one adapter, one cable type and this check, the socket question is solved for good — whichever continent you wake up on tomorrow.
