Tested: USB Tester (Reveals Lossy USB Cables)

I always wondered why charging an USB device like my smart phone somtimes take ages to complete. To analyze it I bought an USB Digital Tester. A useful device to find the culprit and to see what is going on. See which cables are lossy, and which are good!

Great video

Should be noted that the 5,000mah is the cell at 3.7, not output voltage. So the Wh reading should be used. If you correct for the voltage though it’s 3,416mah which is 68% efficiency, more than half but it’s alright I guess

Would this be able to tell you if the usb c cable has a 56k ohm resistor in it (like the nintendo switch pro controller cable) or if it has normal 10k ohm resistor?

Is the product plastic or metal

[@sirflooz]

Casing is plastic, connectors have metal shielding.
