Portable USB-C Power Analyser

The Diymore USB C Power Meter is a compact inline tester that measures voltage from 4V to 30V and current up to 12A, showing instantaneous power on a 1.06in TFT display. It targets engineers, hobbyists and repair technicians who need to verify charger output, cable quality or power-bank capacity without a bench multimeter.

Use-case fit and limits

Suits anyone who wants real-time read-outs of voltage, current, power, energy, capacity, elapsed time and CPU temperature across three switchable screens, with automatic data recovery after a disconnection. Not for users who require programmable electronic-load functions, automated logging to a PC, or measurements beyond the stated 30V and 12A limits.

Deciding specification

The hard measurement ceiling of 30V and 12A determines whether this tester can cover your source; if your charger or solar panel can exceed either figure, the meter will not read it safely.

Questions about this item

What type of USB-C charger or cable must I already have to use this meter?

The meter plugs between any USB-C source and load, so you need a USB-C charger, power bank, or cable that delivers 4–30 V and up to 12 A.

Will this tester work with my older 5 V phone charger and legacy USB-A cable?

Yes — the meter accepts 4–30 V and 0–12 A, so a 5 V USB-A charger via a USB-A-to-C adapter falls inside its measurement range.

How can I verify the meter is measuring correctly after I connect it?

The 1.06 in TFT shows live voltage, current, power, capacity, energy, time and CPU temperature; values changing smoothly while charging confirms operation.
