Review: Accurate, Detailed, and Perfect for Power Testing - Excellent tool for monitoring USB power delivery in real time. The display is clear and easy to read, and it provides detailed data including voltage, current, wattage, accumulated mAh, and Wh. I’ve used it to test chargers, cables, and device draw under load, and the readings have been consistent and reliable. The PD/QC trigger functionality is a big plus for stress testing and verifying fast-charge negotiation. Build quality feels solid and it handles higher wattage without issue. Great for anyone who likes understanding exactly what their devices are pulling.
Review: WOW, Discover the secrets of your USB power sources - This little device (I have the all USB-C version) does much more than my previous USB power monitor. In addition to Power Delivery, Apple, and Qualcomm Quick Charge QC 2.0/3.0/4+, it can probe a battery/charger for more obscure protocols such as DASH (OnePlus), Adaptive Fast Charging (Samsung), FCP/SCP/SSCP (Huawei), and 4 kinds of VOOC. The user interface takes a bit of learning, but the left/right/enter switch makes things a breeze, especially when compared to my previous USB power monitor that had just one button to do everything. The C3 comes with two Type-A to Type-C adapters which provides it the ability to connect in a wide variety of situations. I used the this device to discover why my Anker 545 Portable Power Station was not delivering 12V on the USB C ports. it turns out that the 545 won't do 12V via PD Trigger, but the same Type C port will do 12V via QC3.0. Go figure. This deficiency seems to be common to a lot of Anker products. When using USB PD, they leave out the 12V profile. Why Anker, why? It is unfortunate that the PC software for this device does not support Linux. I could see people wanting to connect this to a Raspberry Pi or something. Lastly, it is possible to update the firmware even without the PC software. If you hold down the multi-key while connecting it to a PC, the device will go into its bootloader and preset as a USB drive to the PC. You can copy the firmware to the USB drive and tell the C3 to use the file for a firmware update. Sweet! I am very happy with this device. The software seems top-notch and the all Type-C design allows it to be very small. It even came with a tempered-glass screen protector. Nice.

### ⭐⭐⭐⭐ 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.
