Gadget Review: Plugable USB-C Voltage & Amperage Meter (240W)

By admin
All USB-C cables are equal. But some, as the saying goes, are more equal than others.

This little gadget from

Plugable
FAC

is a fantastic bit of kit. Plug your USB-C power supply into

one

end of the gadget, plug the gadget in to your laptop, phone, or any other USB-C device. Watch the screen to see how much power is flowing.

A black and white screen!

A button to flip the display over!

That’s it!

There’s no

or WiFi to get the results out. There’s no flash storage to record anything. There’s no graphs. It shows you volts, amps, watts, and direction of power. That’s all I need it for, and that’s all it does.

As you can see, the screen reacts quickly. So you can get a good idea of what power load your various apps have.

This is great. My work

laptop was complaining that it wasn’t receiving enough power from my USB-C docking station and, with this, I was able to see that it was getting

about 40W.

I was able to test some

cables to see how much power they could support.

Even better, this doesn’t interfere with normal USB-C functions. It happily passed through video, audio, peripherals, etc.

It’s

favours you or not. You can find cheaper ones – but they tend not to go up to

240W.

This is an indispensable gadget – especially if you have

dozens

of cables of uncertain provenance. It’ll tell you just how much they’re capable of delivering.

Now I just need to find a USB-C plug which can actually deliver
