The U96 USB Tester/Meter was a request for a birthday gift. Recipient was very pleased to receive as gift and will be very useful for electronic design projects.

Great meter. The only downside is that it doesn't measure low current consumption... (tested with an Adafruit Circuit Playground and the current draw remains at 0, yet, it works when measuring a phone charging)

Really just jumped on this because it was on sale, but also because I wanted to check my power saving code on some MCUs. Wasn't hoping for much, but I was hoping to see something repeatable between full power ~50 mA and low power in the µA range which I assumed would just show up as 0.000 or whatever. Sadly it doesn't do the job, seems to require at least something in the 100 mA+ range to start registering at all, and is pretty insensitive to small current changes. So probably fine for things like powerbanks, larger SBCs and so on, no good for MCU usage really.

A great little USB tester for the money. Even shows the PD voltages on the D+ and D- lines. Only negative for me is that the display is a little dim unless the ambient lighting is quite low. The smaller is a little ’small’ but overall I am happy with my purchase and I would recommend.

Very handy to k ow how much power things are drawing to calculate appropriate battery's needed. You can also rotate the display witch is really really handy

Great for measuring power drain if you're wanting to power your Pi etc with batteries. Manual could be better...

Excellent quality especially for the price. It makes it easier to test usb devices to ensure they aren't drawing too much power as well as help calculate how big of a power supply a project will require. Should have bought one years ago. As always exceptional service from Pimironi

This is a good little meter. Unfortunately, I wanted to use it to verify some low power projects (

Just the job for testing the consumption of various projects, especially ESP8266 / ESP32 deep sleep power used.
