BFKK UT658Dual USB-C Tester 4-24V 10 Groups

SKU CH-HW4E-91CRH

Measures USB-C and Type-A voltage, current, power and capacity up to 24 V with 10 data groups

  • Measures voltage, current, power, capacity and resistance for complete charging analysis
  • Stores 10 data groups on-screen for quick comparison of test results
  • Supports fast-charge protocols 2.0, 3.0 and 4.0 across Type-C and Type-A ports
  • Monitors charging efficiency to protect connected devices from over-voltage or over-current
  • Compact LCD tester for production verification, engineering tests and DIY diagnostics

USB-C Power Meter for Engineers and DIYers

The BFKK UT658Dual measures voltage, current, power, capacity and equivalent resistance on USB Type-C and Type-A ports. It supports fast-charge protocols 2.0, 3.0 and 4.0 for checking chargers, power banks and cables. Ten groups of data storage let you review results later. The tool suits production verification, engineering testing and hobbyist diagnostics.

Practical Limits of the 4–24 V Measurement Range

The tester operates from 4 V to 24 V DC, so it cannot inspect sources below 4 V or above 24 V. It reads D+ and D- line voltages on the data cable but does not analyse proprietary protocols beyond the listed standards. The two modules are separate; Type-A input must match Type-A output and Type-C must match Type-C for valid readings.

Installation and Common Pitfalls

Connection is plug-and-play with no driver installation required. The most frequent error is crossing the modules — feeding a Type-A source into the Type-C port or vice versa — which yields no data or incorrect values. Ensure the LCD is readable in your lighting conditions and verify the correct port pair before logging any of the ten stored groups.
