Product Description

usb tester power meter electrical meters amp multimeter watts watt c testet

For a multimeter, the Plugable USB-C Amperage and Voltage Tester (USBC-VAMETER) manages to fit a lot of useful features into a sturdy little package. About the size of a USB flash drive, this bidirectional USB tester allows for full USB data passthrough while it monitors USB-C power and charging, measures voltage and amperage, even visualizes the directional flow of electrical current–all in real time.

Connect the VAMETER inline between a USB-C host system like a laptop, tablet, or cell phone and a charger to use it as a USB voltage meter or power consumption meter. An updated OLED screen means a brighter and easier-to-read display in any lighting conditions, and a new orientation button lets you flip the screen with a click.


How it works: This meter is a transparent interposer–it should not interfere with the USB data (1.1 through 3.1 Gen 2), USB-C Alternate Mode video, or USB-C charging. The meter can be used in-line with USB-C docking stations, chargers, and other USB-C accessories. The meter is able to achieve this without interfering with normal USB-C operation as it only taps into the power (VBUS) and ground connections to measure values and leaves the data lines untouched.	Common uses: Connecting between a USB-C host system like a laptop, tablet, or cell phone and a charger to monitor charge information. Connecting between a USB-C host and docking station to monitor charge information. Connecting between a USB-C host system and a USB-C bus powered accessory like an external hard drive, flash drive, etc to measure power draw of a device. Testing for USB-C port spec compliance such as a VBUS hot condition, voltage drop under load, etc.	Important notes: This meter is not meant to replace professional USB-C test equipment, it is designed for quick/easy measurements for users of any skill level. Not compatible with Intel Thunderbolt 3 devices. Specifications: Meter is bidirectional and can be connected in any direction Supports 4-22V, 50mA-6.5A operating range Does not support USB-PD R3.1 Extended Power Range (28V, 36V, and 48V) Supports all USB data (1.1 through 3.1 Gen 2)

Additional Notes and In the Box:

In the box you will receive one USBC-VAMETER.

Please note that under normal circumstances the meter will not power on without a device connected (host, charger, accessory, etc) at both ends. If the meter turns on when only connected at one end, the attached device is "VBUS hot" which is against USB-C specifications.

Does what it says, but isn't perfect

Reviewed in Canada 🇨🇦 on May 11, 2017

Product works as advertised.

Yes, it shows you voltage, current and current direction on the screen. It's pretty cool to plug my charger into my laptop and see 20v flowing in, then plug my phone into the laptop and see 5v flowing out.

I've connected it to several chargers (USB-2.0, USB-C 5v, USB-C 5-20v) and it always seems to be giving reasonable numbers.

When connected in-line with my USB-2.0 meter (USB-2.0 charger, USB-2.0 meter, USB-2.0->USB-C cable, USB-C meter, USB-C device), the displayed current values are identical although the USB-C meter shows a significantly lower voltage (eg 4.9v-vs-4.5v, 5.0v-vs-4.8v. This could maybe be voltage drop in the cable - although it seems high. I don't have the right cable/connector combinations to be able to reverse the meter order and double-check this.

It's not perfect though:
* The display isn't quite as shown in the product images. It alternates between "voltage & current" (for about 3 seconds) and "current direction" (for about 1 second)
* The body is bulky: this means that it won't plug into my phone without me removing the phone case (Google Pixel with a Spigen Ultra Hybrid case). Also when it's plugged into my laptop (Asus C302 Chromebook) the meter body sits lower than the laptop case so you either have to prop up the corner of the laptop (which is annoying) or have it rock on the meter (which is annoying and would probably break the meter plug over time). A 3" pigtail cable like my USB-2.0 meter would have solved this issue - there's presumably a good design reason why this wasn't done. If I don't get bored of watching the meter readings, I may find myself picking up a 6" USB-C to USB-C cable in the future to solve this

See attached images: you can see the two display modes and also the random cable I've wedged underneath the laptop in order to lift it up slightly and take the strain off the meter connector. The third photo shows how the bulk of the device height is below the male connector - this is what causes the height issues but is probably necessary for internal component mounting. If you plug the meter in upside down then it doesn't cause any height issues... although it does rather reduce its usefulness.

One last point. I thought the display was scratched-up when I received it. There's actually a film over the display. Peel this off and the display is shiny and scratch-free.

Fantastic for monitoring/Troubleshooting electronic device charging.

Reviewed in Canada 🇨🇦 on November 20, 2018

Verified Purchase

I'm starting to get into battery chargers that use Power Delivery (PD) to charge laptops, and I wanted this device to help me learn more as I go forward - and in case I need any help with those battery chargers not working or not supplying enought power - this would help me to see that.

THE GOOD: The device is very small. Very compact. Easy to store anywhere. It only take a couple of seconds for it to boot up. It will boot after you plug your USB-C power cable into it that you want to measure the current from. The display is very easy to read. Legible, bright. When the device is off you can't even tell there is a screen there. . It will appear as a mirror until it is powered on - this is normal. This is just like smaller audio players you get from China that use this type of OLED screen as it save power and works really well

DOES IT WORK? I have a power hub that I use to charge all my electronics that shows the current amperage to each device. This USB stick seems to match pretty well exactly to that when showing the amps. Also, it keeps track of how much power has gone through it to your device. This is really a great feature when you know the capacity of your battery and want to know how full it is without turning your electronics on.

Packaging was very small, a cardboard box, and a ziplock bag with the device in it. No waste here, well done.

The voltage shown on the device combines the voltage going through to your device, and the voltage needed to power this USB stick.

CONCLUSION: There are no negatives to this device. Works perfect. Shows exactly the info I need. Measurements match my other devices so I know it's accurate. For the $ it's definitely worth it! FIVE STARS!

It's probably ok but I need USB C for testing MacBooks. Not sure how I missed the fact it wasn't USB-C but anyway 20 bucks wasted on my own shoulders for not being cautious enough.

Use this multiple times daily

Reviewed in Canada 🇨🇦 on March 20, 2022

Verified Purchase

I run a Macbook repair business and as part of that, I use this USB-C meter upwards of 20-30 times per day. I've tried nearly every brand and have found that over time, the solder joints on the USB-C male port break and it fails. This one is the first one I've found that feels much more reinforced. No, you can't drive a car over it, but you can feel confident that with normal usage this won't disintegrate in your hands like most cheaper versions.

Does the job

Reviewed in Canada 🇨🇦 on October 1, 2018

Verified Purchase

I wanted to be able to monitor if my devices properly negotiate USB PD and what profiles they choose to do that. This USB-C multi-meter does this job remarkably well.

The screen, although small and very reflective, remains legible and adequately bright (see attached photo). Measurements seem accurate and the refresh rate is sufficient. It worked with all my USB PD 3.0 devices (iPhone, Macbook Pro, Anker PD Powercore...).
I can't attest to its compatibility with all the USB-C protocols listed in the description (I strictly use it in a no-data set up).

At 25 dollars, this is not very accessible. But considering the prices of competing devices, this seems like the best bang for the buck.

The only drawback I found is, while this gives the total charge that goes through (in mAh), I doesn't provide total energy (which I find to be a more relevant indicator). You can do a simple calculation to get it but it remains annoying.

It also does feel a bit flimsy but if you don't rough it up too much, it should last.

great product for MacBook /macbook pro users with usb-c

Reviewed in the United Kingdom 🇬🇧 on March 10, 2017

Verified Purchase

Given all the fun and games over usb-c cables and not being sure what works with my MacBook Pro i wanted to get one of these for usb-c (i have something similar for usb2) Its very well made with aluminium case. Plug it into the usb-c device and the cable into it and you can monitor the voltage/current through the device and whether the power is from the mac or to the mac. I tried it with an 87W power supply and it was interesting to see the different supply voltages/currents as the MacBook Pro charged. I also used it test a device to test a device that was causing some problems. it turned out ti was drawing more power than the mac could handle. I also used to it test some cables from various companies to see the various voltages.currents being drawn. I really like this product. A colleague was impressed it it to. It will be interesting to see how long the oled lasts... i've had some issues with other oled products in the past!

A handy tool for checking out usb PD devices.

Reviewed in the United Kingdom 🇬🇧 on January 15, 2018

This meter is great for quickly checking whether a usb c charger is behaving as expected. It shows at a glance the voltage, current, and direction of flow on the usb power lines. For the £16 I paid, it’s a no brainer when the market has so many shoddy usb c adaptors our there.

I purchased this tool when I went looking for a charger for both laptops (60W) and the iPhone X (9V, 15W). After reading some deeply concerning reviews of certain usb c chargers, I went looking for a USB-PD power meter.

Nathan K’s review Of the Anker 60W (https://www.amazon.com/gp/customer-reviews/R2UR46XXKO1HKW?pldnSite=1) adapter sent me towards Plugable. Now I wonder if I should follow suit and get the full sniffer as well as the power meter.

Not the best construction

I bought this to replace a Satechi unit whose display became unreadable at 5 months, with the refund Amazon kindly provided. It is similar in form to the Satechi unit. The most noticeable difference was the scratches on the soft plastic screen, which obscured one digit. I polished off the scratches, but the fact they exist does not indicate any measure of quality control of the build process. The usb-c connectors connect better than the Satechi ones did.

Was fantastic when I got it. Tested it just one 4 different cables. Then connected to a new device and the screen stopped working. Still allows charge through device but shows nothing. Sending back for a refund! A shame as I really liked the product.

Would I purchase this again - yes!

The product works as expected, build quality is very good. Have used it on my laptop and 2 mobile phones to show the total power delivered.

Would be great to update the product to indicate mAh delivered which is why it gets 4 out of 5.

Update:. So the screen on my device started to fade and display stray pixels. I emailed pluggable and they were more than happy to send another unit. Brilliant service and thoroughly recommend them!
