What is the USB-IF Certificate?

The USB Implementers Forum, Inc. is a non-profit corporation founded by the group of companies that developed the Universal Serial Bus specification.

The USB-IF was formed to provide a support organization and forum for the advancement and adoption of Universal Serial Bus technology.


The forum facilitates the development of high-quality, compatible USB peripherals (devices), and promotes the benefits of USB and the quality of products that have passed compliance testing.

Why You Should Use Genuine USB-IF Products?

If you use a counterfeit or uncertified USB-C cable, there are problems that can arise from it.

  Problems may occur when you connect a USB-C compatible device, such as a phone, to a USB-A port on your laptop or hub. The USB-C compatible phone may be designed to take in 3 amps of power, while the laptop’s USB-A port can only deliver 2 amps.

If it is made with a 56K ohm resistor and the right components, a cable that complies with USB-IF standards will ensure the connected device only draws as much electricity as the power source can provide.  In this case, if the laptop can only provide 2 amps, the phone will only draw 2 amps.


A counterfeit cable, however, will not ensure the device only takes in the number of amps that the power source can provide. In this case, if the phone tries to draw 3 amps from a laptop that can only provide 2 amps, it can cause permanent damage to both devices. It could cause both devices to overheat and even cause a fire or an explosion.


How to Identify the Difference?

Make sure that your USB-C cable has a USB certification mark. Check to make sure that the product packaging has a USB certification logo on it. Make sure the logo on the packaging and/or cable is straight and not crooked or blurred. If the packaging has spelling errors, is damaged, or seems incomplete in any way, it is probably fake.


The package for a counterfeit cable has no certification logo printed on it.


Inside the cable, there are only four wires attached to the USB-C connector.
