Landing in a new country only to discover your phone, Kindle and laptop can't plug into anything is a modern travel nightmare. Condé Nast Traveller UK asked a full-time digital nomad to sort the good adaptors from the duds, and the picks are worth knowing before your next flight.

The shortlist covers five kits: the Universal Travel Adaptor Worldwide takes best overall, the Decqle Pro Universal Travel Adapter wins for built-in charging, the TESSAN Universal Travel Adapter Worldwide is the budget option, the UGREEN Nexode Pro is the one for fast-charging several devices at once, and the Shuomao UK to Worldwide Travel Adapter offers the widest global coverage. That range matters because "adaptor" means different things depending on how you travel — a weekend in Paris needs far less kit than a months-long work trip across three continents.

The most useful part of the guide isn't the products, though. It's the adaptor-versus-converter distinction, which trips up plenty of first-timers. An adaptor only changes the shape of your plug so it fits a foreign socket. A converter changes the voltage. Europe runs on 220V while the US uses 110-120V, so if your device isn't dual-voltage, plugging it in with just an adaptor can fry it outright. Most phones, laptops and camera chargers these days are dual-voltage (check the fine print on the plug — it'll say something like "100-240V"), but hair dryers and other high-wattage appliances often aren't.

Which adaptor to pack depends on your gear and your destinations. An all-in-one universal adaptor is the low-effort answer: one brick that handles UK, EU, US and Australian socket types, so it works whether your next stamp is Japan or Argentina. If you're the type travelling with a phone, tablet, smartwatch and e-reader simultaneously, prioritise a model with multiple USB ports or USB-C fast charging rather than a single socket — otherwise you'll be playing charger rotation every night at the hotel.

Why it matters: chargers are the cheapest travel insurance you can buy. A dead phone abroad isn't just an inconvenience when maps, translation apps, boarding passes and hotel bookings all live on it. Picking the right adaptor before you fly costs about the same as an airport sandwich and saves a scramble at arrivals. It's an easy win for anyone heading outside the UK, from gap-year backpackers to business travellers carrying more kit than they'd like to admit. Credit: Condé Nast Traveller UK.
