Powerwerx Watt Meter-PP, DC Inline Power Analyzer, 45A Continuous, 12 Gauge with Anderson Powerpole Connectors

Works as described. If you want the monitor a battery over a long period where the monitor will be used for different equipment, just leave the monitor connected to the battery.

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.

I use this meter to monitor my Lifep04 Lithium Battery Packs which I use for Ham Radio. The meter has many peak and max readings which rotate in a cadence. Nice product.

Great vendor to work with! Excellent products.

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.

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.

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

Easy to connect, simply to use. I use it with a portable solar powered Ham Radio station.
