You may have noticed that charging your devices via USB may work well on one charger, but not so much when plugged in somewhere else. More than likely, you keep these chargers around in case they’re needed, but wouldn’t it be better to know which gadgets are actually good and bad? That’s the idea between QooPow’s original qualMeter and the more advanced qualMeter X.
Though useful in its own right, the qualMeter X is made to be extensible, allowing you to add extra features to your device using the XT package. This expansion pack is available (and over-funded) on Kickstarter as of this writing in two different versions.
The XT Basic includes a MicroSD card for firmware upgrades and a beeping indication system, while the Network version gives you the ability to test RJ45 network cables and even RJ11 phone cables.
