What to look for when buying USB-C cables and adapters

USB standards have a long history, and they've gone through plenty of changes since first implemented in 1996. The premise behind it all is providing a way to standardize cables, connectors, communication, and power transfer between electronic devices. Some of the first equipment to use USB were the really old, brightly colored iMac and speakers. USB was designed to be the one standard that does it all, and that's pretty much how it all worked out.

The USB-C specification is one of those USB standards. Released in August 2014, it's a set of rules for a small 24-pin reversible plug connector to use with existing USB system. Some of the connections inside are used to tell which way a cable is plugged in; others are used to transfer data or power; and some are used as a dedicated connection to allow both sides to talk to each other, and make sure the right amount of electrical current is being sent to safely charge or power one device from the other. Though it was released in tandem with the USB 3.1 specification, USB Type-C rules are only for the physical connections — data speeds are covered by other rules. You can think of USB-C as a set of rules to make smarter USB plugs, cables, and connectors.

The best parts of the USB-C specification are also the parts that make buying the right cable or adapter important. With USB-C, all connected devices can send power out as well as receive power in. You can charge a phone or set of headphones or anything else that uses the USB-C spec with another phone that uses the USB-C specs. You could (in theory) build a cable that can pull power from several Lumia 950s or Nexus 6Ps and charge the battery in a MacBook if you wanted to.

AUKEY CABLE USB-C also includes a native way to "fast-charge" one USB-C certified device from another safely using that dedicated connection channel mentioned above. It's also an open specification that anyone can use and alter to better suit their needs, and companies making phones have done just that. This means buying the right cable is a must or you can risk damaging the things you're plugging in or even starting a fire.

But don't fret. You don't need to know all the rules in the USB-C spec or how it can tell which way it's plugged in or any of the other geeky details to make the right choice if you follow a few easy tips when you're buying a cable or connector. These three tips will help you get exactly what you need.
