Got a random cable laying about and need to know what it's capable of? For this job, the right tool is the Treedix multifunction USB cable tester. This pocket-sized gadget can tell you everything you need to know about a cable (probably more than you need to), and it does it quickly and reliably.
The USB cable tester is a small box featuring an array of ports. There are USB-C and USB-A output ports and corresponding USB-C, Lightning, miniUSB, and microUSB 2.0 and microUSB 3.0 input ports for testing cables.

The unit can handle a multitude of tests, from basic functions showing whether the cable can handle data and power transmission, along with that protocols, a printout of active lines in the cable, a resistance test, and an eMarker chip test.
If the cable being tested is equipped with an eMarker chip, you will also get information about the maximum current and voltage the cable can carry, the data transfer rate, the type of cable, and even the length of the cable.
