This video is why I ordered one, after evaluating several of these analyzers -- THANK YOU. Mine arrived yesterday... I spent a lot of today playing with it -- it's quite awesome. It's one of the more expensive analyzers in this class but I have no regrets in spending the US$70 for it (on AMZ). The PC software was a bit dodgy for me at first, but it started working fine at some point for a reason that I cannot pinpoint (it was interfering with my mouse cursor periodically). The tool needs some work but gets the basic job done. (I am mostly interested in the power contract negotiation between the power source and the sink device, and it does a fair job of that, but the screen layout and behavior needs work.)
the expansion port under the back cover is for a load tester that can be purchased with the unit and attaches to it. thanks for the awesome review, i think ill be buying this over the fnb48 .
A while ago I had a short video comparing the functionality of this USB metter under the name Shizuku (maybe the original product) with some other USB metter like Fnirsi FNB48. You can find on youtube "Review USB Multimeter and USB Tester Shizuku (KT002/AVHzY CT3); FNB48; UD18"
hello nice video, i should measure the power watts of usb 3.0 and pd power supplies, i'm looking for a cheap one that does just this, which one do you recommend?
I have a question: I have an iPad and iPhone wich have "USB-C to USB-C" and "USB-C to Lightning" cables to charge. So they both use USB-C plug to connect to the charger which as an USB-C port. So if I want to monitor and test the voltage and current for these devices, this tester will not help me, because I can't plug it into the USB-C port on the charger, right? So I need to find a tester like this with USB-C plug?
I came across your video while doing research. I have a question for you. I want to test the 20 Volt/12 Amps 240W SUPERVOOC charging adapter and find out its actual values. I want to measure directly at the adapter output and I want to measure from the cable output after plugging the cable into the adapter. The adapter has a TYPE-C output, 240 Watts gives the value as 20 Volt/12 Amps. I have researched a lot of products, there are products that see 240 Watts and can reach much higher Volt levels than 20 Volts, such as ChargerLAB Power-Z KM003C - Power-Z C240 or PLUGABLE USB C Power Meter Tester 240W, but these testers are not in the Ampere range of the SUPERVOOC adapter (I need 20 Volts/12 Amps, but I could find a maximum of 6 Amps in the meters I researched), so I think a healthy measurement cannot be made. What can I do about this, how can I reach the correct measurement, is there a device you can recommend?
This tester doesn’t support QC5, and PD3.1 Does that mean it will not allow charging in these protocols? I know it will give maximum 100W but can it actually allow those protocols?
Question, is it easy for a beginner like i am to meassure the charging current of a USb device like for example a wireless air duster i bought? It has a USB-C port and i plugged in my old USb tester from Portapow and a normal USB-A Apple Power adapter. Now my USB Tester shows only 2V instead of 5V? Is it possible that the portable air duster destroyed my cheap USB Tester? It also showed 50watts for some seconds, really strange. Thats why i want to buy a new USB tester, but a good one. So is this device in the video plug and play, just connect the USB-C cable to the USB tester and the USB tester to the USB power adapter?
@@voltlog no, it was 5V but i think it has to be kind of defective because it somethimes charges the unit with 3.7A all of a sudden and sometimes it drops to 0.350A, so really strange behaviour. I also have the feeling that the USB-C port is kind of loose. Can you tell me how i can meassure the resistance of USB-C cable with this device? It has the internal function but i dont know how i should plug the cables.
@@voltlog hey, i need to check an USB Power adapter with PD 30W. I can use the auto enum function or fast charge trigger to check if the power adapter accepts 20v for example but this is all the time with 0A current. Is there a way to check devices with lets say 20v 1.5A ? Can the internal modul deliver 9v or 20v as well or only 5v? Im scared of destroying the modul when i use fast charge trigger 20v and activate the load modul with 1.5A current.
@@voltlog I think my AVHzY is not working correctly anymore or maybe i make a mistake. I want to check USB-C devices in the last week and like you know i have the same device as you, the USB-A version with the internal load. But the USB-A version has also USB-C "in" and USB-C "out" ports. When i use them i often get totally wrong data, the voltage is right but the ampere is way to low all the time. Maybe i need the AVHzY USB-C version of the device? But again 70 Euro is not nice. For example i want to check the charging current of an Ipad, so i plug an USB-C cable into the PD Port of my USB Power Adapter and the other end of the cable to USB-C "in" in my AVHzY. Then i plug my lightning cable to USB-C "out" in my AVHzY. I get only 8 Watts or something like that. When i put my very cheap USB-C tester with male USB-C port directly into my USB Power adapter it shows the correct data with 5V and 2.2 A. Maybe i make a mistake here? Did you experienced the same with your device?
That does look nice. I have a similar model from Power-Z. (AKA: Chargerlab). Model FL001 SUPER. Mine uses micro SD for user storage rather than onboard chip. Not sure how good the PC software is, I have not used it yet, I'm going to guess not as good as the one you found. I don't believe this has the oscilloscope feature, would be nice to have. But it has a fancy voltage and current graph. Otherwise seems comparable. The PD trigger and cable resistance tester are quite nice. I dislike the little multi key thing, it's terrible for UI. Buttons would have been much nicer. I mis-trigger buttons all the time.
Even if the later digits aren't totally accurate in an absolute sense, higher resolution can still be useful for relative measurements or changes over time, as long as the readings aren't too noisy. You just have to keep its limitations in mind and make your own judgement as to whether it's worth its price for your purposes :)
I have the 58 but might send it back for this. Mostly because the load module. I see that being the most useful feature for me to stress test devices and quickly determine capacity.
