Travel adapters: plugs, voltage, and what to pack.

Two separate questions decide what you need abroad: does the plug fit (adapter), and can your device handle 230V (converter)? For phones and laptops the answer to the second is almost always yes — which makes packing simple.

The 60-second version

Every USB charger, phone, laptop, camera battery charger, and tablet made in the last decade is dual-voltage — the fine print reads "Input: 100–240V ~ 50/60Hz". These need only a plug adapter. Single-voltage devices (hair dryers, curling irons, some CPAP machines) need a heavy voltage converter or, better, a dual-voltage replacement. Full explainer: adapter vs converter.

Best strategy for 2026: skip plug adapters for your chargers entirely. Pack one multi-port GaN charger plus a single universal plug adapter — one wall socket abroad then powers everything you own.

All 45 country guides, by region

Each page gives the plug letters in use, the mains voltage and frequency, whether a US Type A plug physically fits, and what to pack. Grouping matters more than the country list: one Type G adapter covers the UK, Ireland, Singapore, Malaysia, Hong Kong and the UAE, and one Type C adapter covers most of continental Europe — which is how a two-adapter kit ends up covering a 40-country itinerary. Plug shapes are indexed separately in plug types by country.

Europe 16 guides

Type C two-pin everywhere except the British Isles; 230V throughout.

Asia & the Pacific 12 guides

The most varied region: 100V in Japan, 220–240V nearly everywhere else, five plug shapes.

The Americas 8 guides

Mostly Type A/B at 110–127V, so US plugs fit — with Argentina, Chile and Brazil as the exceptions.

Middle East & Africa 9 guides

Type G and Type C dominate at 220–240V; South Africa uses its own Type M.

Packing questions the country pages do not cover: airline rules for chargers and power banks, the best travel chargers of 2026, airline-safe picks, retractable-cable adapters for carry-on, and travel adapter vs converter if you still own a single-voltage appliance. Brand-level options are at the brand index — Zendure and Nomad both build travel-specific units — and single-product detail is in the EPICKA universal review and Zendure Passport III review. Device-specific: MacBook Air, GoPro, DJI drones.

FAQ

Do I need a voltage converter for my phone charger?

No. Phone, laptop, and tablet chargers are universally dual-voltage (100–240V). You only need the physical plug shape to match.

Will a travel adapter charge my laptop?

A plug adapter passes power through unchanged, so yes — your laptop's own adapter does the work. Just check the travel adapter's amp rating (most handle 8–10A, far above any laptop's draw).

What plug type does the UK use?

Type G — the large three-rectangular-pin plug, at 230V. It's also used in Ireland, Hong Kong, Singapore, Malaysia and the UAE, so one Type G adapter covers a lot of ground.
