The Mathorn MPMA-10CA60 is a compact cable and power meter adapter for USB-C to USB-A connections that provides real-time measurement of voltage, current and power. Designed for quick verification of charging behavior and basic data link performance, the adapter reports VAW (voltage, amperage, wattage), supports USB Power Delivery up to 60W, and handles data rates up to 10 Gbps. Its integrated LED indicates status at a glance, making it convenient for troubleshooting and monitoring power delivery between hosts and devices.
Advantages
The adapter combines power measurement and data path compatibility in a single inline device, enabling simple inspection of charging parameters without bulky instrumentation. Supporting up to 60W USB Power Delivery and 3A current allows testing of a wide range of chargers and cables. The LED status indicator provides immediate visual feedback while the support for up to 10 Gbps data rates permits basic verification of high-speed connections. Its compact form factor makes it portable for field use or on-desk diagnostics.
Suitable for
- Verifying charger output and USB Power Delivery behavior up to 60W
- Monitoring current draw and voltage on USB-C to USB-A connections
- Basic data link checks for cable and device compatibility at up to 10 Gbps
- Troubleshooting charging issues between hosts, hubs, and peripherals
- Portable field diagnostics for technicians and engineers
Key specifications
- Connection type: USB-C (male) to USB-A (female)
- Power Delivery support: up to 60 watts
- Maximum current: 3 A
- Measurement: reports voltage, current and power (VAW)
- Data rate support: up to 10 Gbps
- Status indicator: integrated LED

How to use
Insert the USB-C male end of the adapter into the host or charger USB-C output, then connect the USB-A device or cable into the adapter's USB-A port. The adapter begins reporting voltage, current and power values when a load is present and USB Power Delivery is negotiated. Observe the LED to check basic status; for detailed measurements, monitor the values displayed by the adapter according to the device's output method. Use the adapter inline during charging or data transfer to verify expected behavior and to identify anomalies such as insufficient voltage, excessive current draw, or interrupted data links.
Usage recommendations
Use the adapter within its specified limits: do not exceed 60W power delivery or 3A current. For reliable measurements, ensure secure and proper connections and avoid using damaged cables. When testing high-speed data links at or near 10 Gbps, keep cable lengths short and minimize actions that could introduce signal degradation. Store the adapter in a dry, dust-free environment when not in use.
