If you want to know precisely how fast your power supply charges your devices, Plugable has a new product just for you. Launched today, the USB-C Power Meter Tester (USBC-VAMETER3) connects to any device via USB-C and monitors the flow of electricity, showing you amperage, voltage, and wattage on an easy-to-read display. .
The meter is about the size of a USB stick, is rugged, and will not interfere with data flow to a connected device. Plus, it’s bi-directional, so you can plug it into your laptop to check the performance of your power supply, and then plug in your smartphone to see how fast the power flows. It also works great for seeing how much power accessories like external hard drives and webcams are drawing from your computer.
A year ago, the USB Implementers Forum certified USB-C Type-C 2.1, allowing chargers up to 240 watts, a staggering increase over the previous 100-watt standard. And while no current charger takes advantage of that massive power flow, Plugable’s new power meter will be able to assess them when they start to hit the market. And the meter’s two-year warranty means it will most likely last long enough to test them.
Please note that Plugable intends this device for non-professional use. It is intended to give an at-a-glance analysis of energy transfer rates. Therefore, it cannot replace professional level energy meters. And unfortunately, this power meter is not compatible with Intel Thunderbolt 3 devices; We have asked Plugable to clarify this limitation.
