I want to test my 20 Volt/12 Amps - 240 Watt SUPERVOOC charging adapter with Type-C output and find out its actual values. 12 Amps is a high value and almost no device measures this amperage level. As far as my research, I saw that C4 models offer high amperage values and may be suitable for this job. Which model should I choose exactly for healthy measurement? C4, C4L or maybe C5. With which model I can see 20 Volt/12 Amps 240 Watt levels.
