adapters share the primary function of converting high-voltage AC input into low-voltage DC output. This is essential for powering devices such as routers, LED lights, industrial machines, and consumer electronics. Despite differences in size and performance, their goal is fundamentally the same\u2014providing stable and safe DC power.<\/p>\n<h3 class=\"\" data-start=\"1278\" data-end=\"1313\"><span class=\"ez-toc-section\" id=\"Common_AC_Input_Requirement\"><\/span><strong>Common AC Input Requirement<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"\" data-start=\"1315\" data-end=\"1621\">Another similarity lies in the AC input range.
