Review on ⚡ YOTINO USB Voltage/Amps Power Meter, Tester Multimeter for Assessing Charger, Cable, PC, Power Bank Performance by Johnathan Stoner

Works well. It's nice to have multiple memories to record different readings. The screen is not very bright, it is difficult to see in bright light. Unfortunately, the microUSB port is short-lived. It is only held by 4 very small soldering points. My circuit board broke off and is no longer usable. If you want a more powerful microUSB connector, you'll have to open the box and glue the connection in place.
