The author recently acquired some USB-C cables with screens that display power consumption of connected devices, satisfying their power consumption monitoring addiction and ensuring devices charge at expected speeds. The cable, costing 6.72 EUR, supports USB 4 and works well with a USB-C dock and DisplayPort connection on a high-resolution monitor. However, due to the cable’s quality, longevity is uncertain. The author warns of potential security risks, suspecting a malicious chip could be hidden in the cable, but suggests searching for similar cables with LED displays online. For more advanced power consumption monitoring options, the author recommends exploring GitHub repositories for measuring devices.
