The Plugable USBC-VAMETER and USBC-VAMETER3 are designed specifically for USB-C connections and are incompatible with USB-A due to differences in connector design, power delivery, and data protocols. 

Key Differences: 

  • Power Delivery: USB-A typically supports up to 4.5W (USB 2.0/3.0), whereas USB-C PD can handle up to 100W (USBC-VAMETER) and 240W (USBC-VAMETER3).
  • Power Limitations: USB-A does not support USB-C Power Delivery, making the meters ineffective.
  • Protocol Differences: USBC-VAMETER devices rely on USB-C PD negotiation, which USB-A cannot provide.

The USBC-VAMETER and USBC-VAMETER3 are exclusive to USB-C because of their reliance on advanced power and data protocols. Using them with USB-A is not possible due to physical, electrical, and functional limitations.
