This works well and is accurate enough for my needs. PD and QC options work well. USB pass through works well. The screen is bright and easy to read. Some of the fonts in the menus are a bit small for my eyes, but it's a reasonable trade-off for the small size. The ability to provide external power to the device allows it to accurately measure the current consumption of the device under test.One of the items I tested has another connector very close to the USB-C port. The power meter, as small as it is, blocked access to the connector when externally powered. For such situations I recommend getting a short 20cm (8") USB-C extension cable.

As mentioned max measurable voltage / current 26V - 6.0A in specs, but measuring max. 20V - 3.1A = 63W (PD3.0 PPS) while charger can supply 20V - 5A = 100W.

This is an impressively capable USB A and USB C tester. It'll let you put any power supply through its paces (especially with the optional electronic load), tell you more than you probably ever wanted to know about power and charging protcols, and it'll even let you do some truly unwise things.You can even connect it to your computer and log data for immediate or later perusal.All that capability begs for far better documentation. Surely someone at AVHzY could find or hire a native speaker for every language the instructions are provided in. This applies to the device as well. One of the messages in particular is quite odd, referring to the device under test as a "guy". As things are now, I haven't worked out every function this tester is capable of, mainly because the instructions are so dire.

This is an initial review; I'll post some pictures and other things later on. However, let me state out the gate that if you can afford just one tester, this should be it! Oh, and the firmware is upgradable with the seller releasing updates on a regular basis!Sure, it's more expensive than those cheap $10-$20 ones, but you get a LOT in this package:USB-A male to femaleUSB-C female to female(these are mostly independent; you can test A-male in to C-out)Advanced charge protocol testing with bypass switch; this supports (nearly?) all protocols including VOOC / Dash (but alpha or beta not sure). This becomes really useful when trying to figure out if some wall-wart with barely legible markings is just a dumb PS or more, and what modes, not to mention testing.Testing cables INCLUDING READING THE E-MARK CHIPS OF USB-PD CABLES! This has already proven useful to me as I was troubleshooting a Prymax 300Wh power station: turns out it doesn't like e-marked cables but works ok with an unmarked one! (Also telling me that particular USB-C cable WAS unmarked and therefore technically non-USB-IF compliant.)This particular kit comes with an external variable constant-current load which is oh-so-very useful finding out what wall warts will REALLY support. Using this I have also discovered that the HP Pro 3500 computer at work just connects the USB port to the power supply with no protection or intelligence whatsoever! I pulled over 3A from that USB-A port! The much newer Dell Inspiron next to it, OTOH, has full protection and cuts off just over 2.4A with an alert to Win10 even. However, your typical USB-powered device (including power banks) won't pull that 3A because they're under the safety assumption they're connected to something much smaller.This also has an internal load that can be used to test cable resistance along with the external one. The instructions aren't clear on these procedures (there are 4 with one not supported due to an (as of yet?) un-obtainium part. Once I figure it out this should be very useful classifying cables. Note that this is ONLY for power and (very unfortunately) doesn't test for data on a cable with more than 4 wires.This, then, is the only real gripe: without plugging it into some other device there's no way to know if the cable with pass data or is just one of those cheap "charge-only" cables. I've been trying to find testers that will do this similar to network cable continuity testers; I may have found one but it's kinda pricey and I already have a real network tester that tests supported data speeds: however no such thing exists for USB unless you're willing to shell out at least a thousand dollars!I promise more to come with pictures!
