Review on 🔧 DROK Small Digital Multimeter DC 6.5-100V 50A: Voltage, Amperage, Power Energy Meter for Precision Monitoring - LCD Digital Display by Adam Matthews

I have ordered two of these so far to make power supplies for ham radio and 3D printing applications and they are AWESOME! First of all, the power consumed over time. I helped determine the hardware power requirements for various deployments. I've had people asking me to build boxes with some of these just because of the amazing data you get when you have to run on battery power for long periods of time. One thing I didn't understand from the start (because I didn't read the instructions fully) was that they come pre-configured for a 100A shunt and you must set that value or your measurements will be severely distorted. It's easy to modify and just know something to set/test before you head out into the field wondering why your gear is drawing almost twice the current you expected. :)
