Introduction

It's been a while since we launched our ChargerLAB POWER-Z KT002. While it's been a favorite among tech enthusiasts, we realized we haven't provided detailed tutorials. Let's jump in by introducing the protocol detection feature.

Since it has only one button - MultiKey, the operation is a bit complex, and we already divided it down into three sections in our pervious article of unboxing of the ChargerLAB POWER-Z KT002, you can go check it out.

First, when testing a USB-A charger, like this Huawei charger, simply connect its male plug directly to the tester.

Of course, you can also use a USB-A to USB-C cable to connect the KT002's USB-C port to the charger. This is more convenient because you don't have to tilt your head to see the test data.

You can also use a cable to connect a USB-C charger, but it has to be a dual USB-C cable.

Then, you will get this note. It means you need to disconnect any device connected to other ports, because the high voltage may ruin your device.

After a short wait, it will end with a beep, and the results will be presented in the form of a checklist. Specifically, the supported protocols will be displayed in green, while the unsupported ones will be in red, making it very intuitive.

Since it's a phone's original charger, this OnePlus WARP charger supports fewer protocols, making it less suitable for other devices.

Finally, let's test it on a power bank. Take this all-protocol power bank for example. Its USB-A port supports VOOC series protocols.

Summary of ChargerLAB

The ChargerLAB POWER-Z KT002 is a versatile USB tester that allows you to measure voltage, current, power, and capacity. It also has a protocol detection feature that can identify the fast charging protocols supported by a charger or power bank, just like our KM003C!
