USB-C Power Cords May Be Hazardous to Your Device

So-called USB Type-C power cords offer a number of potential advantages to multiple device users. But, as one Google engineer found, not all USB Type-C power cords are created equal.

According to a report recently posted on CNN Money, Benson Leung has been reviewing USB-C cords listed for sale on Amazon after connecting his laptop computer to a USB-C power cord that had been wired incorrectly. The power cord rapidly drained the laptop’s power, permanently damaging the electronic circuitry, and rendering the computer useless.

Leung’s mission is to help prevent other USB-C users from suffering a similar fate. “I have gotten fed up with the early cables from third-party vendors that so blatantly flout the specifications and I want to take them to task,” he says. “You may not just get weird behavior from your devices with these bad cables…What some of these vendors are doing is downright dangerous.”

Mastering High Voltage: The Importance of Accurate Test Equipment

This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems — is essential for safety, reliability, and regulatory compliance. It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.
