POWER-Z USB PD Tester MFi Identification PD Decoy Instrument KT001
A part of the review has been auto-translated.
This an extremely capable product for the price. In particular, in conjunction with a PC app it allows you to capture and display USB PD protocol messages. Other products that do this are several times more expensive. However, the documentation is hard to find and hard to understand. Overall, things are a little lacking in polish. But for the price it's a great deal. This model (Power-Z KT001) is the same as the Kotomi Premium and the AVHzY CT2 (except that the Kotomi has a battery; not sure about the AVHZyY). To find the app, firmware update and docs look at the AVHzY web site, or search this web site for the Kotomi Premium.
From the many features you can also know for the real capabilities of your usb charger: which usb coding it have and so how much (and if) it can fast charge.
