This is potentially the best thing I ever bought. https://www.amazon.com/dp/B0DYJL5Z67/?_encoding=UTF8&pd_rd_i=B0DYJL5Z67&ref_=sbx_be_s_sparkle_ssd_tt&qid=1782381706&pd_rd_w=9Spk9&content-id=amzn1.sym.aaeb8a5f-b8dc-4432-a5cb-67b920049d8c%3Aamzn1.sym.aaeb8a5f-b8dc-4432-a5cb-67b920049d8c&pf_rd_p=aaeb8a5f-b8dc-4432-a5cb-67b920049d8c&pf_rd_r=C68881WJ5Y2FF90G92P3&pd_rd_wg=hX72H&pd_rd_r=eb2794bc-3da7-43fc-8d23-2f20db498fcf&pd_rd_plhdr=t
Power-Z is a power tester that can read the e-mark. This cable is probably the best one for measuring power, but not the best choice for sorting cables. I have at least one cable where the e-mark lies about its capabilities (claims to be 40gb/s, but does not have the super speed wires), and the Power-Z is not capable of detecting this. This Treedix tester is a cable tester that will show you which wires are connected and read the e-mark https://www.amazon.com/dp/B0DYJL5Z67 It does not measure voltage, current or power, but is self powered (AAA battery) and is more appropriate for sorting cables.
Charging cables, especially 2M long cables are usually only USB 2, so 480Mbs max. To find out what a cable is acually good for, you need one of these: https://www.amazon.com/dp/B0DYJL5Z67 Unfortunately, with USB C cables there is a huge selection of different types of cables, and you can't tell from looking at them what features the cable implements.
