MakerHawk USB Multimeter USB Voltmeter Ammeter Load Tester USB Voltage Current PD Battery Power Capacity Charger Type C Meter Tester LCD Display Cable Resistance QC2.0/3.0/4.0 N20 1.54 Inch Screen

Really impressed with the MakerHawk USB Multimeter USB Voltmeter Ammeter. It’s super easy to use and gives accurate readings for voltage, current, and power consumption. The display is clear and bright, making it easy to monitor devices while charging or testing USB ports. Great little tool for troubleshooting cables, chargers, and power banks. Feels solid for the price and works exactly as expected. Definitely worth buying if you work with electronics or just want to keep an eye on your charging setup.

My experience with the MakerHawk USB Multimeter can be summed up in one phrase: "works well after I figured out how to use it." When I first unboxed it, I was a little overwhelmed by the amount of information on the screen and the various buttons. There wasn't a clear, intuitive path to simply measure voltage and current right away, and I felt like I was fumbling through the settings. It definitely required me to sit down, read the instructions, and look up a few videos to understand its full functionality. Once I got the hang of it, however, the device proved to be incredibly useful and accurate. It's a powerful tool for anyone working with USB devices and power delivery. I've used it to test cables, monitor charging speeds on my phone, and troubleshoot power issues with small electronics projects. The ability to see real-time data on voltage, current, power, and even the total energy consumed is invaluable. The screen is bright and easy to read, and the rotating display feature is a nice touch. Despite the initial learning curve, I can now confidently say that the MakerHawk USB Multimeter is an excellent piece of equipment. It's a reliable, feature-rich tool that provides the data you need to ensure your USB devices are functioning correctly. The frustration of the initial setup has been completely replaced by the satisfaction of having a powerful tool in my kit.

Works as described. My one concern is the back surface is the bottom side of the PC board making it potentially susceptible to ESD. An insolative cover sheet of some form other than the PC mask would have been a much more robust protection for the device.

I love real time information, and this little meter gives! So far I've been able to evaluate batteries and charging rates of a few devices that I was having issues with. While it can't fix anything by itself, it's certainly a big help in evaluating chargers & battery conditions.

Fun gadget to see what power draw different USB devices pull. Helpful for troubleshooting devices that aren't working either. If you like to mess around with USB devices in a tech sort of way, this is a great little tool.

The item does absolutely every single thing it claims to. It may be a bit daunting if you haven't yet looked into things, being greeted with another language and all. But so long as you're on the ball, you'll have an easy enough time with it. The software is a bit, meh... Not in functionality, it does what it should. Presentation could be better, with digits running out on either side of certain margins, but it's no big deal. The bigger thing is getting the software at all, I found a link in someone else review, followed that back to the wrong product, then browsed the directories of the mediafire tree until I found what I needed... and even then, it was a bit vague as far as knowing where I should be, what I should be using, etc. But it worked out. This along with the load pictured in the one image, are a fantastic pairing for troubleshooting purposes. The meter can do quite a bit on it's own, but bringing in a tune-able load is an entire other ball of tech diagnosing abilities brought forth. Thank you very much for taking the time to make an actual worth while product, it is worth every penny.

There is a lot of good things this product does and I feel it’s well worth it’s price. Checking power bank and device battery health, checking the capabilities of power supplies, quality and condition of cables, etc etc. Recently for me the BT connection to and iPhone and usb connection to windows started randomly disconnecting. Using a different usb tester shows me that it’s the TC66C being finicky/failing. It’s main functions work fine. I’ve had it and been using it for 6 months. The iOS app is probably one of the worst apps in the App Store and certainly the worst app on my phone. It opens to a black screen the persist way too long, then you get a Chinese ad to buy something that I generally can’t read. Finally you get into the app to see the screen size is not formatted for the iPhone X or newer (works just looks back see my image). I really need to look to see if anyone made an alternative app. Again though for the price and usefulness I recommend this product. Could be better but what couldn’t?

This is one of my favorite purchases from Amazon in a while. I didn't realize how much I needed it until I had it. I was able to go through all my cables and purge the ones that had some bad internal connections, was also able to check on some USB power banks, and also test each of my USB wall blocks. It's amazing how much you learn in a short time about your different chargers and cables and how different they can be. Some wall blocks put out too much voltage (which is why I bought this tester, because I had a brand new wall block fry a security camera by putting out too much voltage), and it's also fascinating that some cables seem to intentionally provide imline voltage control even one paired with a wall block that is putting out too much juice. The device itself is really easy to use and has lots of intuitive features. This was money very well spent for me and although I'll probably never use it as much as I did in the first 24 hours, it's a handy thing to have around because it's hard to test USB stuff with a regular meter. Mostly it's just cool as all get out.

Good

De muy facil uso, creo que el manual lo podrían colocar en alguna página, esta de un tamaño mínimo y creo le falta detallar cuidados y precauciones al usarse

Nice easy to use Device for checking how much power is flowing on various USB supplies and devices to be charged. Great for this.... Unfortunately USB-C doesn't seem to work and doesn't enable flow through USB-C or even power the device as the other formats do. Unfortunately also the QR code doesn't lead to the right instruction manual. Apart from USB-C and the instructions not being available, it would have got a 5 star.

Was working fine until at one point part of the screen for some reason stopped working. Went to the electronic recycling world.
