The Best Travel Adapters (and How to Not Fry Your Devices)
A travel adapter changes the plug shape; it does not change the voltage. Get that one distinction right and the rest is easy. Here's what to look for — the all-in-one worth owning, the cheaper region route, and the USB-C upgrade that replaces half your chargers.

A working charge is part of a smooth arrival — your map, ride app, eSIM, and this site all need a live phone the moment you land. A travel adapter is the cheap thing that makes that possible abroad. The only trap is thinking it does more than it does: an adapter changes the plug shape, not the voltage. Get that straight and the rest is a five-minute decision.
The one to own: a universal all-in-one adapter
For most travelers, a single universal adapter covering the four big plug types (UK, EU, US, Australia) is the sensible one-purchase answer — it works in the large majority of countries, and a good one has USB-C and USB-A ports built in, so it charges your phone straight from the wall without a separate brick.
What to look for: built-in USB-C (ideally PD/fast-charge) plus a USB-A port, a sturdy sliding-pin mechanism that grips the socket, a fuse, and a compact shape. Skip the giant “does everything including a nightlight” models — they’re bulky and you won’t use half of it.

The cheaper route: region-specific plug adapters
If you only travel within one region, a small pack of that region’s plug adapters is cheaper, lighter, and less to lose than a universal unit. Europe (Type C/F), the UK & Ireland (Type G), and North America (Type A/B) each have their own.
What to look for: a grounded version if your devices have a three-pin plug, and a two-pack so you can charge your phone and laptop at once. Buy the plug type for your actual destination — check which your country uses before you go.
The real upgrade: a GaN USB-C wall charger
If you carry a laptop, the piece that genuinely improves travel is a compact GaN USB-C charger — new-generation chargers that are far smaller and cooler than old bricks, and powerful enough (65W–100W) to charge a laptop and a phone from one small unit, over one cable standard.
What to look for: GaN (for the small size), enough wattage for your laptop (65W handles most ultrabooks; 100W for bigger machines), two or more USB-C ports, and pair it with a slim region/universal plug adapter. One charger, one cable type, half the bag clutter.
For the hotel desk: a travel power strip
One socket is never enough. A compact travel power strip or charging station turns a single foreign outlet into several, so your phone, watch, laptop, and camera all charge overnight from one adapter — genuinely useful for couples and families sharing a room.
What to look for: a compact/flat design, a mix of AC sockets and USB-C/USB-A ports, and — importantly — one that accepts 100–240V input (most do; check) so it works worldwide with a single plug adapter.
The one rule that saves your devices
Say it once more, because it’s the only thing that goes wrong: an adapter changes the plug, not the voltage. Your phone, laptop, tablet, and camera are almost certainly dual-voltage (look for “INPUT 100–240V” on the charger) and need only an adapter. Hot appliances — hair dryers, straighteners, curling irons — often are not, and plugging a 110V-only device into 220V will destroy it. For those, buy a cheap dual-voltage travel version, or just use the hotel’s. Do that, and a $15 adapter is all you need.
Quick answers
Do I need a voltage converter or just a plug adapter?
For almost all modern electronics, just a plug adapter. Phones, laptops, tablets, cameras, and most chargers are 'dual voltage' (they accept 100–240V), so anywhere in the world they only need the plug shape changed — that's what a travel adapter does. Check the small print on the charger or device: if it says 'INPUT 100–240V', you're fine with an adapter alone. You only need a bulky voltage converter for single-voltage, high-wattage appliances — a hair dryer, straightener, curling iron, or travel kettle rated for only 110V or only 220V — and honestly it's usually easier to buy a cheap dual-voltage travel version of those, or use the hotel's, than to carry a converter. So the rule: adapter for electronics, dual-voltage appliance (or the hotel's) for hot things.
What's the best travel adapter to buy?
For most travelers, a single universal all-in-one adapter that covers the UK, EU, US, and Australia plug types and has a couple of USB-A and (crucially) USB-C ports is the sensible one-purchase answer — it handles nearly every country and charges your phone straight from the adapter. If you only ever travel within one region, a small pack of that region's plug adapters is cheaper and lighter. And if you carry a laptop, the real upgrade is a compact GaN USB-C wall charger plus a slim adapter, which replaces your laptop brick and phone charger together. Match the choice to how you travel, and don't overspend on features you won't use.
Will my phone and laptop charger work in other countries?
Yes — virtually all phone and laptop chargers are dual voltage (100–240V), so they work anywhere once you change the plug shape with an adapter; you don't need anything special beyond that. The exceptions are older or cheap single-voltage chargers and, again, hot appliances (dryers, straighteners). Modern USB-C 'PD' (Power Delivery) chargers are especially travel-friendly because one compact GaN charger can fast-charge a phone and power many laptops. Always glance at the 'INPUT' line printed on the charger to confirm 100–240V before you rely on it abroad.
Can I bring a travel adapter and charger in carry-on?
Yes — plug adapters and wall chargers are fine in carry-on (and you'll want them there, not in checked luggage, so you can charge en route). The item that has airline rules is a power bank/portable battery, which must go in carry-on (never checked) and is capacity-limited — see our power bank guide for the numbers. Plain plug adapters and USB chargers have no such restriction. Pack your adapter, charger, and cables in your carry-on personal item so you can top up during layovers.
