Powerwerx Watt Meter, DC Inline Power Analyzer, 45 Amp Continuous, Wire 12 Gauge, with Anderson Power Connectors

Works well and seems to be very sturdy.

I use it inline with my ham radio equipment and was experiencing a loss in radio RF output. I could look at the meter and see that I wasn't drawing the amps I should have and a quick inspection found that one of the power leads was loose. Tightened it up and all was well in the kingdom.

I loved this thing. Easy to use and provided valuable information. I was so happy I recommended this to a friend. But he got a dud. Had quality issues with one connector. When he tried to get a replacement, Amazon was out of stock so he tried to fix the connector himself. Then when using it, it had other operational issues. But since he had worked on the connector, they wouldn't take it back. So he is stuck with it. I like mine but feel bad that I recommended to a friend.

In the process of going "off the grid" for ham radio. This nice meter simply plugs in with TRUE Anderson PowerPoles, telling me exactly what is happening with my lithiumironphosphate battery

Great little thing that does the job well indoors. Bring it outdoors and it's really hard to see what is displayed.

Did not work. Blank screen.

This has worked since the day I got it. It's terrific.

Useful when charging a battery and while connected to radio during POTA. Glad I added it to my portable rig.
