I am looking for a USB power meter, i.e., a device that you can plug between a normal USB charger and a USB-powered device and that tells what is the voltage supplied by the charger and how much current is transferred.
Ideally, I'd like to have a meter with the following specifications:
The meter has USB type A connectors (type A plug in one end, type A socket in the other end), so I can use it with any USB charger with a type A socket, and then just connect a suitable cable to charge devices with either USB micro-B or USB C connectors.
The meter supports modern USB power delivery standards, it works fine with e.g. Qualcomm Quick Charge technology, it does not interfere with the voltage negotiation, and it is happy to accurately measure voltages larger than 5V and currents larger than 2A.
Reasonable price tag (below 50 EUR).
Based on the reviews, it seems that Satechi type-C power meter works pretty well with modern high-power USB devices, but has type C plugs, so it is not that convenient if I want to use it with devices with micro-B connectors.
