This is the single best Prime Day deal for international travelers

There are a ton of tech products on sale for Amazon's Prime Days (Oct 6 & 7), but there's just one that anyone who travels internationally should own. The Anker Nano Travel Adapter is a brilliant way to save space, travel light, and keep all your devices charging while roaming the world.

Why the Anker Nano Travel Adapter is a top companion

I picked up the Nano Travel Adapter during a previous Prime Day sale, and it instantly proved to be worth its $20 cost. The most obvious feature is the adapter's thin frame, but that's not the only way it excels. I found its four USB ports to be handy when I didn't want to plug in another power adapter. The fold-out prongs for European countries worked well and felt secure.

The beauty of this power adapter is that it can be used in the US, too. If you have room in your cable bag, then it can live in there for all kinds of trips. The one downside of this product is that its USB ports only provide 20W of total power. That means using all those ports at once will make it take longer to charge your devices. Otherwise, this power adapter is ideal in pretty much every other way.

The Anker Nano Travel Adapter is 23% off right now during this sale, down to $20. Even after more than a year of use, this is the cheapest I've seen it. If you travel to various countries, even occasionally, then this gadget might be down to impulse-buy territory.

There are other power options for travel

If you're looking for a travel charger that's more powerful, offering 100W of USB charging power, then you should look at Anker's new 4-in-1 Universal Charger.

This product is ideal for people who want to fast-charge their laptop and phone, but who don't want to carry more than one power adapter. There's no AC outlet, so all your charging will need to be done through USB-C and USB-A ports.

I've tried the new Universal Charger at home, and its screen offers neat insights into temperature, country support, and power usage for all the devices plugged into it.

Since the Nano Travel Adapter and this one offer different capabilities, it's not clear-cut which one is the best overall. More likely, these different adapters will work best for different types of trips or different types of travelers.
