support?\u003c\/h4\u003e\n\u003cp\u003eA: The KWS-X1 supports a comprehensive range of fast-charging protocols including USB Power Delivery (PD) 2.0, 3.0, and PPS, Qualcomm Quick Charge (QC) 2.0, 3.0, and 4.0, as well as FCP, SCP, AFC, PE, DASH VOOC, Super VOOC, MTK, and OC2.0\/3.0\/4.0. It features automatic protocol detection so you can instantly identify what protocol a charger or cable is using.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use the KWS-X1 to test both chargers and USB-C cables?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The KWS-X1 Type-C tester can be used inline between a charger and a device to measure real-time voltage (up to 40V), current (up to 12A), power (up to 280W), and ripple — making it ideal for evaluating the performance and quality of both USB-C chargers and cables.\u003c\/p\u003e\n\u003ch4\u003eQ: What is ripple measurement and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: Ripple refers to small fluctuations in DC voltage output from a charger. Excessive ripple can indicate a lower-quality power supply that may not charge devices efficiently or safely. The KWS-X1 measures ripple at a 2–5 MHz sampling frequency, giving you a clear picture of charger output quality and stability.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What fast-charging protocols does the KWS-X1 Type-C tester support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The KWS-X1 supports a comprehensive range of fast-charging protocols including USB Power Delivery (PD) 2.0, 3.0, and PPS, Qualcomm Quick Charge (QC) 2.0, 3.0, and 4.0, as well as FCP, SCP, AFC, PE, DASH VOOC, Super VOOC, MTK, and OC2.0\/3.0\/4.0.
