Voltage & Minimum Volts (V, Vm)
The displayed Volts (V) value is the average voltage from the last screen refresh. The displayed Minimum Volts (Vm) value is the minimum voltage or “sag” measured on the source side, since the meter’s last startup.

Watt-hours (Energy) (Wh)
The displayed value is the total energy delivered in Watt-hours since the meter’s last startup. It is measured from the load side for the most accurate results.

Amp-hours (Charge) (Ah)
The displayed value is the total charge delivered in Amp-hours since the meter’s last startup. It is measured from the load side for the most accurate results.

Watts (Power) & Peak Watts (W, Wp)
The displayed Watts (W) value is the average Watts (Amps * Volts) from the last screen refresh. The displayed Peak Watts (Wp) value is the maximum watts measured since the meter’s last startup.

Good enough for field work
5 Stars
Good enough for field work
We often have to take power draw measurements in the field and this little device works great. It's accurate enough for what we need it for.Attached photo shows power supply (black), PowerWerx Meter, and a programmable Power Load (green display) being used to test. A calibrated multimeter reports actual voltage (Fluke, yellow). The power load is reporting downstream from the powerwerx unit.The power load was set for 200W. Amps are being reported correctly. Voltage and Amps on the PowerWerx varies by 0.5 Volts (lower) and 0.75 Amps (higher).

This meter is easy to use and quite accurate. The Powerpole connectors make it easy to move the meter to various locations as I monitor or troubleshoot my system. Now I can tell what is going on with my system at a glance. This meter removes the guesswork from diagnostics, and the running Amp-Hour total helps me to keep track of my battery's State Of Charge.

This does exactly what it's supposed to. I'm into amatuer radio, and this meter will help out tons with monitoring battery levels when operating in the field.

This meter is a must for a portable radio setup. It has many uses, but as a readout link between my Bioenno battery and SOTA radio is its primary job

Great meter, do NOT pay more than $15 for this! At~$60 this is a total rip-off, verging on criminally overpriced!

3.0 out of 5 stars 1st one was accurate, not so much with the second one.
Reviewed in the United States on April 16, 2021

I've come to rely heavily on my first Powerwerx wattmeter. So much so that I have used it as a benchmark to compare other meters accuracy too. It is also in almost every one of my YouTube videos, K8MRD RADIO STUFF, where I operate portable ham radio. It is a staple in my kit. I have boasted about the quality and accuracy on many videos and live streams over the last couple years. I finally purchased another one as one of my cheapo ones melted in the Texas sun. After plugging it in I found that it was reading .05 volts lower than my other meter. Now I understand that .05V isn't much, but I get the same results with the cheap $15 ones. At $60 I would have thought Powerwerx would have some quality control. I guess not. Maybe my expectations are too high, but I'm pretty disappointed. Especially since I know for a fact I have sent them many customers over the last couple years. I wonder how many other people got less than accurate meters. I will be returning this one. It's a shame.

It's good, it's relatively accurate. But my unit has super high-pitched cool whine
So bad that I simply don't want to keep this unit but it's already here and I need it for a project. The quality is...well just buy a 16$ clone and not a 60$ rip-off. Buy some ear plugs if you want one too.
