Start of a new era

The USB-C connectivity is the new type of standardization the industry is gearing towards.  Many technology companies have embraced the new port and a handful of them have already came out with products using USB-C ports. From laptops, phones and monitors, the transition from legacy USB-A to USB-C will be a bumpy one.  


We at CharJenPro are committed to help the consumer easily transition legacy USB to the new USB-C world.  CharJenPro is in front of the discussion in the tech community and updating the changes for our customers to simply keep them current.

USB-C, USB-A, Micro USB, Mini USB... What's going on?


USB-C, also known as USB Type C or USBC, comforms to the USB-IF standardization.  It is important to understand the difference between each connection.

USB Type-C port can handle all this...

USB 3.1, USB 3.0, USB 2.0... Now what's that all about?

USB 3.1 Gen 2 is the latest version following USB 3.1 Gen1, also known as USB 3.0, but very minimal devices to take advantage of USB 3.1 Gen 2 as of now. 

USB 3.1 Gen 2 transfer speed tops out at 10 Gbps again not many devices can take advantages of USB 3.1 Gen 2 speeds.

USB 3.1 Gen 1 (USB 3.0) tops out at 5 Gbps, which still is some blazing transfer speeds. A lot of devices currently use these speeds.

USB PD (Power Deliver) 2.0 handles 100 watts of power!​


All backwards compatible that means your current usb ports are still usable depending on the port connections: USB C, USB A, Micro USB, etc.

You can only take advantage of USB 3.1 Gen 2 speeds of 10 Gbps if inputs from the laptop and the device (lets say a phone) connection has both USB 3.1 Gen 2 specs.  If not, then it'll use the lowest speed spec. of between the two connected devices.  


  • Example: If the laptop has a port USB 3.1 speeds but the phone port has USB 2.0 speeds then the data transfer rate will be USB 2.0 speed. Comprende?  This is 95% of the case with USB-C equipped devices out currently.

Now, but slowly, and the near future, combining USB 3.1 or USB 3.0 and USB Type-C connections, you can charge a full size laptop!  No need for a separate A/C port and proprietary charger to lug around.  Again, the physical charger itself would need to meet USB 3.0 or USB 3.1 specifications to take advantage of the charging speed.


Video Connections as well!

Four data lanes are integrated in the USB 3.1 cable to also connect DisplayPort and HDMI video signals. Yes, you can connect to monitors too!
