Review on ⚡️ RGBZONE 150 Amps Power Analyzer: High Precision RC Watt Meter for RC, Battery, Solar, Wind Power by Tyler Blake

It works exactly as intended. Measures real-time, peak and cumulative total power. Similar models appear to be sold by US dealers for $14-$18, so $16.xx is acceptable. A better, brighter screen might be on my wish list, but it's good and legible in most situations. It was truly a plug and play performance monitor. I would buy again.
