Review: Very cool bit of kit, very useful - The most capable analysis device for usb-c and thunderbolt at anywhere near this pricepoint, bit of an indulgence for myself but certainly if you are in the business of diagnosing usb/thunderbolt cabling issues you should have one
Review: Thunderbolt cables specs revealed - This is a nifty little device that allows you to see the voltage, charging and (what I cared about the most) specs of Thunderbolt cables. There are tons of cables out there that claim to be Thunderbolt but they’re not. With this device you can check every cable. The only caveat: it’s very difficult to use and the online manual seems like it’s written by electrical engineers rather than by someone who understands what the average user wants to do and how to do it. So be prepared for some digging.

## Questions & Answers

**Q: I need to test the power on pc ports while using 20gbps external drives.  will this support that?  if not how high will it go?**
A: Yes, it works.
I tested it with a Lexar NM620 512GB M.2 NVMe SSD in an Silverstone MS12 external USB 3.2 Gen 2x2 20Gbps enclousure.

Normaly i get 2100MBps read/write speeds.
When i use the Power-Z to measure the power consumption i get read speeds about 1600MBps and 2000MBps write speed.

**Q: Does this test for faulty/slow (usb 2.0) cables aswell? i need something to verify usb-c cables are 5/10/20/40gbps.**
A: The tester can detect the E-Marker Chip of the cable, which can display its specs info, such as charging speed and data transmission speed.
But most USB 2.0 is not equipped with E-Marker Chip, so the tester cannot test it.

**Q: Can i use a usb-a adapter to test usb-a ports?**
A: It can support testing USB-A devices using a USB-C to USB-A cable.
You can also use a USB-A adapter, but test results may be affected by the adapter.

**Q: How to test chargers with attached cable? Is there a male to female adapter included?**
A: Firstly, there is no male to female adaptor included, but you can also test the charger with attached cable.
Just put the tester between the load (like your laptops, phones) and the attached USB-C cable.
Or simply insert the attached cable into the USB-C Female (Receptacle) of KM003C and connect the tester to an independent power supply.

### ⭐⭐⭐⭐⭐ Very cool bit of kit, very useful
*by A***D on 4 September 2025*

The most capable analysis device for usb-c and thunderbolt at anywhere near this pricepoint, bit of an indulgence for myself but certainly if you are in the business of diagnosing usb/thunderbolt cabling issues you should have one

### ⭐⭐⭐⭐ Thunderbolt cables specs revealed

This is a nifty little device that allows you to see the voltage, charging and (what I cared about the most) specs of Thunderbolt cables. There are tons of cables out there that claim to be Thunderbolt but they’re not. With this device you can check every cable.

So be prepared for some digging.

### ⭐⭐⭐⭐ Very useful device for anyone in the IT industry
*by A***Y on 8 May 2025*

Bit of a niche product and a little expensive, but very useful if you have a pile of random USB-C cables and need to find their current, voltage and speed capabilities. Also good for interrogating USB-C PD chargers. Whilst I appreciate the compact size, it would be good if they made a slightly larger version with a bigger screen.
