Review: Useful tool for USB power debugging - I've used this on multiple occasions to test / debug a slow charging USB port. It is easy to use for the most basic tasks, and fairly easy to figure out the more advanced functionality with a bit of messing around, but has a user guide if needed. It's bright enough to read, easy to carry around, connects and displays data quickly, and not too expensive for the peace of mind of knowing where the issue is. Definitely worth taking with you if you suspect you'll need to test a USB port.
Review: Review of the CT-3: Great USB Meter - The AVHzY is a smart and useful USB meter. It is the very versatile and has the most features of all the meters I own. Supports USB C, USB A, and a Micro USB port for only connecting to the PC or providing power. One of the few testers that can read the e-maker chip of USB-C cables. I find this meter the easiest to use use of all my USB meters. It has a multi button that lets you press and rotate left/right, you'll still need to read the manual as this one button controls everything. Screen is nice and clear. It even came with a free tempered glass screen protector. The fit and finish is good but the stainless steel is edge can be a bit sharp. I only have two things I wish this meter did better: 1) wish it had bluetooth so I could monitor things via a smartphone app or wirelessly. 2) The female USB port is "upside down" (i.e. opposite orientation) of the male USB plug, which is strange to me. Make it so my USB load has to be put upside down when I connect it to the meter. Of my 4 meters, the generic UP-LCDV03, RD UM25C, RD TC66C, and AVHzY CT-3. The AVHzYCT-3 is my fav because it has the most features followed by the very compact RD TC66C because it is pure USB C.

### ⭐⭐⭐⭐⭐ Useful tool for USB power debugging
*by D***L on August 8, 2025*

### ⭐⭐⭐⭐ Lots of capability, needs better instructions...
*by W***H on November 6, 2023*

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.
