Wireless USB Voltage Meter w/ Digital Display (USBTESTER)

Received my two USB testers within a few days. They both worked well, right out of the package. Will come in handy to check out my USB chargers. Thanks!

This device is a welcome tool for the present proliferation of USB powered devices. It gives a digital display of both available voltage and the current being consumed by a USB device. It does exactly what it is built for and we love it. Wish we had this tool years back.

Works great in finding low voltage usb ports

Great price and works as advertised. I ordered the two-pack. Thinking about ordering more.

I've been using the USB-A to USB-C cable to charge my phone nightly at an underwhelming speed. Couldnt tell if it was the power block or the cable. this gadget let me see the cable was not passing on full power. I was able to go through my bin of cables and find one that sends the full 3.1 or whatever voltage is needed for fast charging

Works fine,accurate🙂

Looks great. Should not be described as "Wireless"

Works great

Handy gadget.. Perfect for insuring your power supply is adequate for the device you are using.
