近几年，新标准USB，USB Type-C已经悄悄来潜入市场来到我们身边。也许你还没有意识到也许只是听说过，如下三点帮你快速了解USB Type-C。
Whether you're excited about today's news from the Apple event, or you are looking toward the future of USB technology, there's a handful of exciting new features packed in this tiny cable. The MacBook is the first notebook to use the connection, but it's likely we'll see many other devices following suit this year. In the meantime, here are a few things you should know about USB Type-C:
It's easier to plug in
No more fiddling with the cord to make sure it's plugged in the correct way every time, because both connection ends are the same and there is no "upside-down." Hopefully this means fewer scratches all over your device's charging port area from trying to plug it in with the lights off.
Data transfer and power capability have greatly improved
USB 3.1 Type-C cables offer a transfer rate of 10Gbps, which is double the transfer speed of USB 3.0 (5 Gbps). Additionally, these cables will offer 20 volts and 5 amps of power, compared with the 5 volts and 1.8 amps of its predecessor. This means less waiting around for devices to transfer data or for their batteries to charge.
USB dongles are going to be your new friends (for now)
The Type-C standard hasn't reached widespread adoption (yet). In the meantime, you'll need to collect some dongles to connect your favorite things together (like an HDMI screen, or a device withan older USB version). If you're purchasing a new MacBook, there's a multiport dongle available to make the transition less of a hassle.
