The screen size of the KM003C has increased from 1.3 to 1.54 inches, and the four side buttons have also changed from gold to silver. Aside from that, the color of the UI has become more vivid and dynamic. The small icon in the upper left corner has changed, because the new model now has a built-in gravity sensor for rotation of the display instead of the physical button. The KM003C can provide powerful functions just like the previous generation, such as multiple tests, including voltage/current detection, capacity/energy test, E-marker test, PDO test, protocol, etc. Automatic protocol detection not only supports the above PD3.1, QC4&5, SCP, FCP, AFC, VFCP, UFCS, etc., but also adds MTK-PE, VOOC and SVOOC.
