Anker’s travel charger works in almost any country and is down to $20

If you’ve got international travel coming up, an adapter is essential for keeping your phone, earbuds, power banks, and other gadgets charged. Anker’s Nano Travel Adapter is one of our picks from our guide to the best gadgets for summer travel because it can charge up to five devices at once, yet it’s small enough to fit in the palm of your hand. It’s also available in black for just $19.99 ($6 off) at Amazon, Best Buy, and directly from Anker (with code WS7DV2BNB82J) matching its best price to date.

The Nano’s four built-in sets of prongs should keep you covered in “over 200 countries and regions,” according to Anker. It also features two USB-C ports and two USB-A ports, along with an AC outlet for plugging in a standard wall charger. A single USB-C port delivers up to 20W, which should be enough to get an iPhone 17 to 50 percent in less than 30 minutes. That’s not enough power to charge most laptops, making the USB ports better suited for smaller gadgets like phones, tablets, earbuds, and power banks. You can still charge your laptop, however, by plugging its wall charger into the AC outlet.

What’s more, it’s designed to take up as little space as possible. The adapter’s only an inch thick with its prongs folded in and, at 3.8 ounces, weighs less than a smartphone. Just keep in mind that the Nano doesn’t convert voltage, so you’ll want to make sure gadgets like hair dryers and electric razors support the voltage at your destination before plugging them in.
