  • Measures voltage from 4 to 30 volts for precise power analysis
  • Tracks current up to 6.5 amps to verify charger output
  • Stores capacity and energy data automatically after power loss
  • Supports QC 2.0, 3.0, 4.0 and Super VOOC fast-charge protocols
  • One-button control shows power, watt-hours, capacity and clears records

USB-C Power Analyser for Enthusiasts

This inline tester measures voltage, current, power, capacity, energy, temperature, resistance and charging time on USB-C devices. It operates from 4 V to 30 V and up to 6.5 A, making it suitable for checking chargers, power banks and cables. Data is retained automatically every 30 seconds and restored after power loss. A single button cycles readings and a long press resets the accumulated counters.

Hobbyists and Repair Technicians

The tool suits anyone who needs to verify fast-charge performance or diagnose faulty USB-C gear without a bench multimeter. It supports QC 2.0, 3.0, 4.0 and Super VOOC protocols, though the active protocol is not shown on the display. Buyers who require protocol identification on-screen or need to test legacy USB-A ports should look at alternative equipment.

6.5 A Maximum Current Rating

The 6.5 A ceiling determines whether the tester can handle the load you intend to measure. High-current laptop chargers or multi-device hubs that exceed this limit will saturate the instrument and risk damage. Check your source’s peak output before purchasing.

Questions about this item

What comes in the package and do I need any extra cables to start testing?

The tester is a single USB-C male-to-female cable. Plug it between your charger and device — no separate leads, adapters or power supply are required.

How do I decide which voltage or current range to select on the tester?

There is no manual range selection. The unit auto-ranges across 4 V to 30 V and 0 A to 6.5 A, covering phone chargers up to high-power laptop bricks in one device.

What does the 30 V / 6.5 A rating mean when I connect it to my laptop charger?

It shows the maximum voltage and current the tester can safely measure. Your charger’s actual output will be displayed in real time, letting you verify it stays within spec.
