USB Type-C Charger: The Death of AC Laptop Chargers

With the development of USB ports,(USB 1.0 – USB 3.1) Apple grab the upper hand and releases USB Type-C in the market. Now we have plenty of options for charging your mobile phone these days. Once upon a time we simply had the choice between charging with a wall socket or with our computer and a USB cable, now we have USB Type-C Charger, USB 1.0, USB 2.0, and USB 3.0. So which one is the best? Why the USB Type-C will be a must have for charging and data transmission. Let’s have a comparison.

What is USB Type C?

 

Physically, the USB Type-C port and connector is about the same size with Micro-B USB, this means it’s small enough to work for even the smallest devices.
Starting at 2015, Type-C USB are support to USB 3.1 with the great speed of 10Gbps and has much high power output of up to 20V(100W) and 5A.
Once more, USB Type-C can enable storage vendors to make bus-powered.

 

Why USB Type-C Charger?

 

1: Reversible
Actually, USB Type-C is the child on the block which will soon replace standard USB 2.0 charging cables. The obvious difference is USB Type-C plugs are reversible, so it doesn’t matter which way you plug them in.

2. High Transfer Speeds
USB Type-C is compatible with up to 10Gbps data transfer rates and have much faster data transfer speeds-even up to 10GB, however if your phone has a USB Type-C port and you get a real USB Type-C cable then you will get USB Type-C Charger speeds.

3. Smaller Gadgets and Faster Charging
The big sell for most users is going to be faster charging. USB Type-C can deliver power at up to 100 watts at volts. More unbelievable is that the larger devices can now be charged from USB, including laptops and, monitors. So you can say goodbye to the clunky AC adapters which we’ve been lugging around until now.

 

Port Behavior:

• Downstream Facing Port (DFP) – A host or downstream hub port. Typical of a legacy standard Type-A port
• Upstream Facing Port (UFP) – A device or upstream hub port. Typical of a legacy standard Type-B port.
• Dual-Role Port (DRP) – A port that transitions between DFP and UFP port states until an attach event occurs.
• Power Source or Provider – A source of 5V-20V up to 5A. Typical of a legacy standard Type-A port.
• Power Sink or Consumer – A sink of 5V-20V up to 5A. Typical of a legacy standard Type-B port.

 

What’s the Difference between three different USB Ports?

So, from the charts, we can see clearly that the only major difference between USB 3.0 and 3.1 is that the latter supports double the peak data speeds of the original, actually there are plenty of devices are likely to jump 3.0.
When it comes to speed, you will probably limited by the slowest component in your chain connecting a USB 3.1 device to a USB 2.0 port will limit your speed to 480 Mbps, for example. In reality, hardware components like a hard-drive are likely to be limiting factors as well.

 

So which is the Best?

 

That depends on what you want out of your battery, If you want to extend your devices’ battery life as much as possible, a regular cable charger is your best choice. If convenience is your top concern, then the USB Type C charger for you.
However, with the development of technology, USB Type-C will be widely used in nearly future.

 

When Can We Expect USB Type-C in Nearly Future?

 

Google recently unveiled a new Chromebook Pixel that uniquely features USB Type-C. But it doesn’t just have one on each side thus making the machine more convenient than the new MacBook. We’ll update this story as more popular manufacturers begin to adopt the USB Type-C standard and add it to their flagship devices.

 

Anyway, let’s look forward to the USB Type-C world!
