Review on π UM25C USB Tester - Voltage Current Bluetooth Battery Power Charger Voltmeter Ammeter Multimeter with 1.44 Inch Color LCD Display, USB 2.0 Type-C Cable, Resistance Load, and Impedance Meter by Dustin Woodrow
Works almost - Tester
Good size and accuracy. As a standalone device it is very good. As a remote data logger, it's hard to recommend. I'm trying to use its Bluetooth as a serial RFCOMM device connected to a logging application on a PC. The device keeps disconnecting and not reconnecting. Bluetooth crashes after a few minutes on multiple (two) PCs, tablets and an Android phone. On a PC, communication can be resumed by programmatically disabling and re-enabling the associated COM port, which is a fairly complex system programming task.
