ChargeLab new product. USB power meter with up to PD 3.1 support

With higher voltage (50v) and current (6A)

The device is not PC Software compatible with KM001 KM001C. First versions of application was about 90% Chinese. With almost no English translation.

(Update for 2022-04-05) But that is getting better. Version 1.2.8 is more usable with better English support

Despite the similar name, design is changed a lot since KM001C devices

Protocol MTK-PE is not detected by KM002C

Firmware 1.1.0 is unstable and has to be updated before using the device. Firmware update is possible for Power-Z Lab application.

Power-Z KM001C is USB Type-C tester from ChargerLAB. Nice and slim. With OLED display. With good PC Software. Have similar features to KM001 and same PC Software.

The main issue of Power-Z devices is no good English translation for both firmware and PC Software, But anyway it still a useful tool. And PC Software is actually best in class. Software updates are available at dropbox folder. Firmware update available from PC Software.

Yet another USB Tester with PC/MAC connectivity. This time using Bluetooth.

Device

PC Software

Application is old-shool and simple. It cannot resize to use full screen, cannot autodetect port to use, cannot show large graphs.

Yet another USB Meter. AVHzY CT-2 (ChargerLAB POWER-Z KT001, Kotomi Premium). It can both store curves offline or be used together with PC application.

PC Application

not as good as ChargerLAB Power-Z KM001 has. Poor visualization and export options. But at least it has English language interface. Support site available at http://www.avhzy.com/

Chargelab Power-Z KM001

Nice device to investigate charging issues. See how fast charge works. Investigate power consumption of different devices in different usage mode.

It has PC Software that creates nice charging trends. That is what makes it different from most of USB Meters.
