USB C Cables - 100w v standard

berko_max on 26/05/2025 - 15:57

I've bought so many USB C cables, I've forgotten which ones are the 'better' 100w ones, and which are the cheap ones.

Is there an easy way to tell, or by plugging in can you check?

I have a aliexpress USB Voltmeter, anything the same for USB C's?

That's probably an answer that Benson Leung an engineer at Google can answer. He goes by LaughingMan11 on reddit. Quite active and will probably answer your q (or just search at his past comments)

There's the Chargerlab Power-Z KM003C or FNIRSI FNB58 (both available on AliExpress too).

Note: These are more-so for testing ports rather than cable

  Was gonna say - I have one random generic one that works well enough and would have been a fraction of the price
  
  The issue OP might have is do they have a device that can pull enough power through the cable to tell the difference? Even some of my flimsiest cables can max out charging my power bank (65w) so need something more powerful potentially.
