Q. With reference to USB-Type C, consider the following statements:
1. They support reverse insertion.
2. They can support relatively larger charging currents ranging from 3 A to 5 A.
3. The connector tabs on the Type C chargers were placed on the cable itself, instead of being placed on the device.
Which of the statements given above is/are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 3 only

[D] 1, 2 and 3

Answer: A
Notes:

The European Commission has proposed a plan to harmonise charging ports and fast charging technology for electronic devices — something that could force original equipment manufacturers (OEMs) to adopt a single technology (USB-Type C) for most of their devices. 

About USB-Type C: 

  • Type-C ports support reverse insertion, so one can insert either end of the cable. 
  • Type-C ports can transmit data at a higher rate. 4K videos can be transmitted via a USB 3.1 Type-C port. 
  • Type-C ports support relatively larger charging currents ranging from 3 A to 5 A, and support reverse charging. 

The only disadvantage of Type-C is that the connector tabs for chargers were placed on the device itself. So, any malfunction of these tabs would require replacement of the entire port(Not cable alone).
