USB-C Power Meter Helps You Spot Counterfeit Accessories Before They Fry Your Gadgets
USB Type-C cables are not all created equally. In fact, some USB Type-C cables fail so badly that they will permanently damage your hardware. Benson Leung, an engineer on Google's Pixel team, discovered early last year that there's even more risk to your electronics when you've got a cheap USB-C cable with an older USB connector on the other end that doesn't properly regulate power draw. In an effort to weed out the bad cables from the good, a company called Satechi has released a "Type-C Power Meter" that makes it easy to tell if your USB-C gadgets are at risk of getting fried, or under-powered, by a sketchy accessory. Gizmodo reports: The simple pass-through adapter connects between a USB-C cable and a USB-C device, providing real-time data about the power draw, in either direction, including details about voltage, amps, and the amount of energy that's been transferred since it was first plugged in. The monitor can let you know if an external battery pack is providing the proper amount of power to a smartphone that it claims to, or if your MacBook or Chromebook is receiving sufficient power from a charging cable connected to its USB-C port to actually charge the battery. What the monitor can't do, however, is protect a device if there's a detected problem in the power flow. It's not a surge protector, nor does it have any built-in alarms or warnings because it has no idea what the power requirements are for whatever device you're using it with. You'll have to make sure you're aware of how much power a device is supposed to be drawing, and confirm that it matches what the Type-C Power Meter is reporting, as soon as you plug it in.Read more of this story at Slashdot.
