Macbook/Laptop: USB-C Power Banks

The Universal Serial Bus (USB) is a type of interface used in data and power transfer. So far there have been four versions of USB, USB-C (USB 3.1) being the fourth. Data transfer over USB-C is twice as fast as its blue predecessor USB 3.0 and over twenty times faster than the older USB 2.0.

Indian-American Ajay Bhatt is largely accredited for inventing the USB interface. Way to go Ajay!

 


USB 2.0 delivers the standard 5v 1a that is used to charge most devices (including phones). USB 2.0 is not capable of charging anything sizeable like a laptop quickly. In addition, up until now, USB has been one-directional meaning a device can either charge or use adapters to be charged.

USB-C has multiple power profiles (charging speeds) and intuitive devices will negotiate and charge much faster than previous versions of USB. A charger using USB-C can potentially charge at 20v by 5a equaling 100 watts. That’s 20 times more watts than USB 2.0!

Has anyone else been wondering why in the world Apple thinks it’s okay to ONLY put a USB-C port on their new MacBook?

USB-C is about as small as Micro-USB and as potent as Apple’s MagSafe charger. Sure it might be annoying having to use a USB-C adaptor to connect anything other than perhaps your phone or wall-charger, but if USB Type-C becomes standard then it will be worth the money to invest now.

Although we may not be able to justify Apple’s logic in that decision, hopefully, this article convinced you of USB-C's potential.
