Review on 💡 Musou USB Safety Tester: High Precision Multimeter for Charger, Cable, and Power Bank Testing - Amp Voltage Power Meter with Test Speed, DC 5.1A 30V Capacity - Black by Chris Shepherd

This is the second one I've bought just because I kinda lost the first one. I have other USB power meters, but this one has an elapsed time display, which is handy when I want to know how long it takes to charge or discharge a battery. Compared to other OLED meters, the backlit LCD has mediocre contrast and the backlighting at the bottom of the display is noticeable, which isn't very good. For some reason the display font here is different from the product photos, I uploaded a photo. A different, blockier font is preferable in my opinion, it's a bit easier to read. Accuracy seems fine, at least when tested with 5 and 2.5 ohm (1 and 2 amp, respectively) loads.
