Anker travel charger that powers five devices in 200 countries drops to $20

The Anker Nano Travel Adapter, featured in our roundup of the best gadgets for summer travel, is now on sale. The black version costs $19.99 instead of the usual $25.99, matching its lowest price ever. The deal is available at Amazon, Best Buy, and Anker's own store with promo code WS7DV2BNB82J.

The adapter's main selling point is versatility: four built-in plug types cover outlets in more than 200 countries and regions. It can also charge up to five devices simultaneously, thanks to two USB-C ports, two USB-A ports, and a standard AC outlet for plugging in a regular wall charger.

A single USB-C port delivers up to 20W, enough to get an iPhone 17 to 50 percent in under 30 minutes. That's not sufficient for most laptops, so the USB ports are better suited for smaller gadgets like phones, tablets, earbuds, and power banks. Still, you can charge a laptop by connecting its own charger to the AC outlet.

The device is designed to take up minimal space: it's just an inch thick with prongs folded in and weighs 3.8 ounces, less than a typical smartphone. One caveat: the Nano doesn't convert voltage, so before traveling, make sure devices like hair dryers and electric razors support the voltage at your destination.
