Unlike regular testing devices, there is no digital numbers bother to read on the display, and there are no calculations after the reading. We believe the numbers make no sense to non-tech users. QooPow™ qualMeter translates the number into a set of 6 LED indicators, which intuitively rank the quality of the USB cables/chargers from top to bottom. You simply connect the qualMeter and get to know immediately how is the quality of your cable/charger in a glance.
QooPow™ qualMeter has two main testing modes, cable test and charger test. It automatically switches between the two modes.
The qualMeter has two main testing modes: cable test and charger test.
Charger Test Mode: Charger test mode is enabled straightaway when the qualMeter has been plugged into an USB power source. The orange charger test indicator lights up and it also confirms the testing current is 1A. You can find out the quality of this charger at 1A output by reading the Quality Indicators on the left.
Cable Test Mode: Cable test mode will be enabled when both ends of a cable have connected with qualMeter. The blue cable test indicator will be turned on. You can find out the quality of this cable by reading the Quality Indicators on the left.
Shielded Indication: During the Cable Test mode, the blue shielded indicator will either light up if your cable is shielded, or won't light up if it is not.
