Review on Watt Meter Power Analyzer - Greatlong 200A Power Analyzer with High Precision Digital LCD Screen for Voltage, Current, Power, Charge, and Energy Measurement by Michael Floyd

Let me start by saying that I bought this built in power meter and also a Powerwerx 150A with Anderson 45A Powerpole connectors. It's from Revain, but I bought it direct from the Powerwerx website, for $50 from Powerwerx and $59 from Revain. I assumed these two counters were made in the same factory just with different graphics. I wanted to try this cheaper one and see how it works. I added 45A Anderson/Powerpole connectors. When I measured the battery power it showed 12.25VDC, Powerwerx measured 12.35VDC. My $400 Fluke multimeter read 12.31 VDC. I would need a much larger sample size to judge accuracy. Pros: - I can get three of these for the price of one. Powerwerx Cons: - The wires are a bit short (only 3-4 inches) which means I can flip them how I want, so it's almost a pro for me.
