Reddit reviews MakerHawk USB Multimeter Tester USB Type-C USB-C Voltage Tester Bluetooth Connection TFT Color Display USB Current Power Capacity Charger Amp Temperature PD Meter Tester Voltmeter Ammeter Indicator

I have a Plugable USB-C power meter and a MakerHawk USB Multimeter Tester.

The Plugable I got doesn't match the pictures, but works just the same. It does stick to a USB-C port and in pulling it out its housing sometimes comes loose. It snaps back in place so I'm use to it. It is bare bones but good for a quick voltage/current reading.

The MakerHawk is my new standard power meter for my reviews. It displays more info, has customizable alerts (beep if over 20.1V or 3.1A), and does USB-C and USB-A. I got the Bluetooth model and use it with Windows software listed on the Amazon page. I ended up getting a micro-USB extension cable so I could plug in the included Bluetooth chip with bulkier chargers. The Windows software reads the meter fine and has a nice graph for over time testing. My mix of Bluetooth components (USB dongle on the PC) means the PC can't talk back to the meter. If it did I could reset the meter's numbers and make changes via the PC. From reviews the lack of "write" from the PC is common, so don't count on it. You can see screenshots of the software in one of my newer reviews.

This is the one I bought https://www.amazon.com/dp/B07DCTHWPR/ref=cm_sw_r_cp_apa_j6sQBbYRAN88J

It's build quality is not the best (connector is a bit wobble) but it's been accurate so far.
