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 also features two USB-C ports and two USB-A ports, along with an AC outlet for plugging in a standard wall charger. 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.
