Power-Z KM003C Portable USB-C Fast Charging Tester PD3.1 QC5.0 Digital Voltmeter & Ammeter Power Bank Tester

The most capable analysis device for usb-c and thunderbolt at anywhere near this pricepoint, bit of an indulgence for myself but certainly if you are in the business of diagnosing usb/thunderbolt cabling issues you should have one

This is a nifty little device that allows you to see the voltage, charging and (what I cared about the most) specs of Thunderbolt cables. There are tons of cables out there that claim to be Thunderbolt but they’re not. With this device you can check every cable. The only caveat: it’s very difficult to use and the online manual seems like it’s written by electrical engineers rather than by someone who understands what the average user wants to do and how to do it. So be prepared for some digging.

Bit of a niche product and a little expensive, but very useful if you have a pile of random USB-C cables and need to find their current, voltage and speed capabilities. Also good for interrogating USB-C PD chargers. Whilst I appreciate the compact size, it would be good if they made a slightly larger version with a bigger screen.

Does the job to tell what your USB-C to USB-C really is. Is it a pure USB x or a Thunderbolt 3 or 4? This device will tell you. Also allows to make precise power consumption measurement over a period of time. Kudos to the manufacturer. Such a device is not easy to find. I recommend.

Ich bin absolut begeistert vom ChargerLAB POWER-Z KM003C! Dieses kleine Gerät (gerade mal ca. 4×4 cm) hat es wirklich in sich. Trotz seiner kompakten Größe ist es ein professionelles Messinstrument, das nahezu alle gängigen Schnelllade-Protokolle und -Modi erkennt und analysieren kann – darunter PD2.0/3.1, QC2.0–5, PPS, UFCS, VOOC, SCP, FCP und viele mehr. Ich habe den Tester mit dem "REVODATA Gigabit PoE zu USB-C Konverter Adapter (Typ-C Ausgang Strom & Ethernet 2 in 1, bis 45 W, 5–20 V)" getestet – und der POWER-Z hat alle unterstützten Lade-Modi auf einmal erkannt! Das zeigt, wie leistungsfähig und präzise die interne Protokollerkennung funktioniert. Das Display ist hell, die Bedienung intuitiv, und über den HID-Port kann man ihn sogar am PC mit der Software auslesen oder Firmware-Updates durchführen. Die Protokoll-Erkennung funktioniert sogar ohne angeschlossenes Gerät, wenn man den Tester separat mit Strom versorgt – einfach genial. Zur Bedienungsanleitung: Es gibt einen QR-Code auf dem Gerät, der zur offiziellen Anleitung führt – diese ist allerdings nur auf Englisch. Mein Tipp: einfach die Datei als PDF oder Markdown herunterladen, bei ChatGPT hochladen, und man bekommt alle Erklärungen direkt auf Deutsch. Ein bisschen technisches Verständnis sollte man allerdings schon mitbringen. ⚡ Fazit: Ein echtes Power-Tool für alle, die Ladegeräte, Kabel oder Schnelllade-Protokolle testen möchten. Klein, präzise, robust und seinen Preis absolut wert. Klasse Gerät – uneingeschränkte Kaufempfehlung!

Alot of love has been put into this design and the software that goes with it. The software has a USB-C PD protocol analyzer that shows you the communication between devices as they negotiate the voltage and current levels that will be allowed and supplied which is very helpful if your designing a device that had USB-PD sink or source features which is what I'm doing which is something I have not seen in a device at this price range. This was a pleasant surprise when I started looking into the software features. The firmware is easily updatable via the software also which means you will not be missing out on any new features as the USB protocol changes over time. The display has a very nice layout and is easy to read and and navigation of the features is alright once you get used to what buttons do what. It's surprisingly smaller than I expected which makes it easy to bring along if you want. For me this allows me to quickly verify the power output of battery banks, AC chargers, and the power consumption of devices I use or am testing. The software allows you to graph out everything over time and save it to a file for later use or comparison. I can tell a lot of love was put into this design, UI, and Software and feel like for $100 it's a steal if you can use all the extra features it provides. Chargerlab has a great Blog where they tear down power banks and bigger solar charger systems and show exactly what is inside and what chips were used if your into those types of things. They use this meter to verify the capabilities of all these different products which means they have to make sure the meter is capable of detecting all the latest USB PD and other standards which means this will always be getting updates as things change over time. I would say spend the extra money and buy this one if you want the best.

Non riesco a far funzionare il cambio di orientamento dello schermo con la rotazione fisica dell'apparato, ma per il resto fa tutto quel che promette ed è un attrezzo insospettabilmente utile, che va maneggiato con cura per non sbagliare. Tenere sempre a portata le istruzioni.

Es una herramienta de diagnostico bastante util, si te interesa conocer la capacidad de carga de tus dispositivos, bancos de energia y los protocolos de carga de los distintos tipos de cargadores, ademas de verificar la veracidad de alguno cargadores, en especial los de Apple. Es un poco elevado el costo, pero si eres técnico o un fanatico de la tecnologia, es una buena herramienta.
