Type C Tester KWS X1 Voltmeter Ammeter, 4V to 30V, 12A, Fast Charge Detection
Introducing the KWS-X1 Type-C Tester — a compact, CNC metal‑cased voltmeter and ammeter built for precise fast‑charging diagnostics. Covering 4V to 30V and up to 12A, it delivers real‑time charging power readings and robust protocol detection to verify chargers, cables, and devices. Its dustproof, drop‑proof design pairs with an HD IPS display and three display pages, easily switching views with each press of the button. Fully compatible with a wide range of fast‑charging protocols, the KWS‑X1 automatically detects PD, QC, and other common protocols, making it ideal for mobile devices, laptops, power banks, and testing labs.
Designed for real‑world use, this Type‑C tester provides reliable performance across diverse charging scenarios. It supports automatic protocol detection for PD2.0/3.0, PPS, QC2.0/3.0/4.0, and more, including FCP, SCP, AFC, PE, DASH, VOOC, and SuperVooc. It’s built to ensure safe, accurate measurements when you evaluate chargers, cables, power adapters, and devices, so you can diagnose issues quickly and confidently.
Benefits & Tips
- Easily verify fast‑charging performance and protocol compatibility (PD, QC, VOOC) for devices and chargers.
- Use curve and ripple measurements to assess charging stability and electrical noise, ensuring safe upgrades and reliable operation.
- Keep it handy for field testing or DIY projects — its rugged CNC metal shell protects against dust and minor drops while you test on the go.
