Conveniently fast-charge two devices at once from a single USB-C port for just $20 on Amazon.

Charging two devices at once doesn't necessarily require a multi-port wall plug -- if you purchase the right cable. For example, Anker has a special USB-C cable that splits into two so you can handle two devices at once with a single USB-C port.

And the coolest part? Right now, you can get this 2-in-1 Anker USB-C cable for just $20 on Amazon -- that's 23 percent off -- with a Prime membership. (Don't have Prime? You can sign up for a 30-day free trial to snag this deal anyway!)

This 4-foot USB-C cable saves you the trouble of packing multiples when you travel or digging around for an extra cable (or even an extra plug) when you want to charge your phone and Kindle at the same time.

And this cable supports up to 140W Power Delivery when only one of its heads is being used, so you could even use it to fast-charge your laptop and get it juiced up in no time. It's also smart, able to know when one device is fully charged so it can redirect full power to the other device that's still plugged in and charging.
