120519 USB Cable and Charger Tester – qualMeter X (Advanced)

QualMeter is an easy and cost-efficient DIY device, which can help you to simply diagnose the quality of your USB charging cable and charger in a glance

Unlike those expensive and bulky professional devices, qualMeter intends to provide a compact (portable), easy and simple solution at a fairly low cost. It's designed for non-tech people but can be very handy to tech-savvies for roughly testing as well.
There are no numbers to read, no buttons, no extra operations, no calculations and no technical background is needed. All you need to know is just colors, the Green, Yellow and Red, which correspond to Best(Good), Fair (OK) and Worst(Bad). That's it!

qualMeter has embedded a smart, ultra-low power Micro-Processor. It works seamlessly to provide two major functions, Cable Test mode and Charger Test mode.
There are no number readings and no calculations! qualMeter directly tells you the testing results by LEDs. It's really that simple and easy!

Testing Ports: USB Type C, USB Type AF, Micro-USB, Mini-USB, 30-Pin and 8-Pin.
