Anyone who’s ever said to themselves “Is this $%&@ thing even charging?” might be interested in the new version of Plugable’s voltage and amperage meter.

Plug the USBC-VAMeter3 into your device then plug the charging cable into the meter and you’ll see how much power is flowing and in which direction.

A new version USBC-VAMeter3 launched Tuesday for under $30. It can handle more power, which makes it more useful and less likely to be accidentally damaged.

Diagnose charging problems with Plugable USBC-VAMeter3

The USBC-VAMeter3 monitors and tests the power/charging of any USB-C device up to 240W. “As one of the first devices on the market designed to measure power up to 240W, we expect this to be a useful device well into the future as products begin to take advantage of the PD 3.1 extended power range,” the company said.

The third iteration of the meter can handle between 4.5V and 50V, and between 50mA and 6.5A. It offers +/- 3% accuracy.

With USB-C support, the mini meter can test power going to a MacBook, most iPads and a whole range of accessories. It does not interfere with data also flowing through cables.

The Plugable USBC-VAMeter3 is available now on Amazon.com. It’s $29.95, but a $4 coupon lowers the price to $25.95.
