What the Tech: Travel adapters
When you pack your bags for an overseas trip, power outlets are probably the last thing on your mind. But using the wrong plug or voltage can leave you with a dead phone or a ruined hair dryer.
Different Countries, Different Plugs
There are more than a dozen plug and socket types worldwide. Canada and Japan use the same two-prong plugs we use in the United States. Most of Europe relies on round two-pin plugs (Type C). The United Kingdom and Ireland use three rectangular pins (Type G), and you’ll find that same style in parts of Asia and Africa. Australia, China, and New Zealand use angled flat-blade plugs (Type I). Unless your hotel has a special outlet for travelers, your devices simply won’t fit without an adapter.
Adapters vs. Converters
A plug adapter only changes the shape of your plug so it fits into a foreign outlet. It does not change the electrical voltage. Most smartphones, laptops, tablets, and camera battery chargers are dual voltage, which means they can handle both the 120 volts in the U.S. and the 220–240 volts used almost everywhere else. Check your charger’s label—if it says Input: 100–240 V, 50/60 Hz, you’re safe with just an adapter.
But hair dryers, curling irons, and some older electric shavers are often single-voltage. Plugging a 120-volt dryer directly into a 240-volt outlet can cause it to overheat, blow a fuse, or even catch fire. To use those appliances safely, you’ll need a step-down voltage converter rated for high-wattage devices—or better yet, buy a small dual-voltage travel hair dryer before you go.
Smart Packing Tips
Invest in a universal travel adapter that includes multiple plug types and USB ports. Models like the Anker travel adapter are compact and versatile, letting you charge several devices at once. Some adapters also include surge protection, which is worth having in countries with less stable power grids. If you prefer not to carry a converter, opt for dual-voltage appliances.
If you’re thinking of packing a small power strip, double-check its label. A strip rated for 120 volts only will still need a converter even if your individual chargers are dual voltage.
The Bottom Line
Before your trip, take a few minutes to check every plug and label on your gear. Packing the right adapter or converter is far cheaper than replacing a fried laptop or hair dryer abroad. With a little preparation, you can keep your devices powered up and your travels worry-free.
