Compact DC Power Meter

This pocket-sized meter measures DC voltage from 4.5 to 50V and current up to 12A peak through 5.5×2.5 mm and 2.1 mm barrel connectors. It suits hobbyists, field technicians and engineers who need instant visibility of voltage, current, power, capacity and energy on a single screen. The bidirectional design shows charge and discharge direction for battery work. A 360° rotatable colour display keeps readings readable in tight spaces.

Rotatable Screen & Sampling Resistor

The 360° rotatable colour screen lets you view data from any angle without repositioning the tester. A 0.001R high-precision sampling resistor underpins the stated accuracy for voltage, current and power readings. One-touch mode switching moves between real-time curve display, peak-value capture and CPU temperature monitoring without menus. The package includes only the tester itself; no cables or software are bundled.

4.5-50V 12A Peak Range

The 4.5-50V voltage window and 12A peak current limit define every measurement this unit can perform. Circuits operating outside this envelope will not read correctly and could damage the instrument. Buyers who need higher voltage, higher sustained current or AC measurement must choose a different tester.

Questions about this item

Will the 0.001R sampling resistor or the DC 5.5×2.5/2.1 connectors need periodic replacement?

The 0.001R sampling resistor is a fixed internal component and does not require scheduled replacement. The DC 5.5×2.5/2.1 male and female connectors are rated for repeated insertion cycles; inspect them for wear or damage if connections become intermittent.

At what point does the 12 A peak current limit activate during continuous operation?

The meter measures up to 6 A continuously and captures peaks to 12 A. Sustained current above 6 A will exceed the continuous rating, so the 6 A continuous limit is reached before the 12 A peak threshold.

How much does the CPU temperature reading rise when the tester runs all day at 600 W?

The built-in sensor reports CPU temperature on the display. At full 600 W load the reading will increase with internal heating, but the exact rise depends on ambient conditions and airflow around the 2.28×1.02×0.63 in enclosure.
