I tested it with a Lexar NM620 512GB M.2 NVMe SSD in an Silverstone MS12 external USB 3.2 Gen 2x2 20Gbps enclousure. Normaly i get 2100MBps read/write speeds. When i use the Power-Z to measure the power consumption i get read speeds about 1600MBps and 2000MBps write speed. **Q: Does this test for faulty/slow (usb 2.0) cables aswell? i need something to verify usb-c cables are 5/10/20/40gbps.** A: The tester can detect the E-Marker Chip of the cable, which can display its specs info, such as charging speed and data transmission speed. But most USB 2.0 is not equipped with E-Marker Chip, so the tester cannot test it. **Q: Can i use a usb-a adapter to test usb-a ports?** A: It can support testing USB-A devices using a USB-C to USB-A cable. You can also use a USB-A adapter, but test results may be affected by the adapter. **Q: How to test chargers with attached cable? Is there a male to female adapter included?** A: Firstly, there is no male to female adaptor included, but you can also test the charger with attached cable. Just put the tester between the load (like your laptops, phones) and the attached USB-C cable. Or simply insert the attached cable into the USB-C Female (Receptacle) of KM003C and connect the tester to an independent power supply.

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! ## Frequently Bought Together - ChargerLAB Power-Z KM003C Portable USB-C Fast Charging Tester PD3.1 QC5.0 Digital Voltmeter & Ammeter Power Bank Tester - Treedix USB Cable Tester Board USB Cable Checker Data Wire with Acrylic Case Charging Test Data Line Type-C Micro Type A Type B - BitTradeOne USB Cable Checker2 [Assembled] Supported USB MiniB/microB/TypeC Cables/USB Digital Tester/USB c Cable Tester/USB Cable Tester Tool / H0.5xW3.5xD2.1 inch ADUSBCIM --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/525056779-chargerlab-power-z-km003c-portable-usb-c-fast-charging-tester](https://www.desertcart.sn/products/525056779-chargerlab-power-z-km003c-portable-usb-c-fast-charging-tester) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
