While calling it strictly &#8220;forbidden&#8221; might be a bit dramatic for everyday life, electricians generally hate seeing empty chargers plugged in for a few solid technical reasons.<sup><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why Electricians Advise Against It<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Vampire \/ Phantom Load:<\/strong> Even when no phone is attached, a plugged-in charger keeps its internal transformer energized, continuously pulling a microscopic amount of power. While modern chargers consume negligible energy (costing roughly $0.10 to $0.50 per year), electricians view any unnecessary live load as poor practice.<br><br><\/li>\n\n\n\n<li><strong>Fire Hazard from Low-Quality Knockoffs:<\/strong> Name-brand chargers (like Apple or Samsung) have robust internal safety circuits. However, cheap knockoff chargers off the internet often skip critical thermal and short-circuit protection. If an internal component fails while continuously plugged into 120V\/240V power, it can overheat, melt, or trigger a fire.<\/li>\n\n\n\n<li><strong>Physical Damage and Short Circuits:<\/strong> An exposed USB tip dangling off a couch or desk still carries a low-voltage secondary current. If the connector contacts water, a metal bedframe, or gets chewed on by a pet, it can spark, short out, or burn out the adapter.<br><br><\/li>\n\n\n\n<li><strong>Component Wear &amp; Tear:<\/strong> Modern chargers use switch-mode power supplies with capacitors and semiconductors. Keeping them continuously energized under line voltage generates subtle internal heat, slowly degrading internal components and shortening the charger&#8217;s lifespan.<\/li>\n\n\n\n<li><strong>Power Surges:<\/strong> During a lightning storm or grid spike, any device physically connected to an outlet can take the brunt of the voltage surge, potentially frying the charger&#8217;s internal board.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">While keeping a high-quality, name-brand charger plugged in won&#8217;t ruin your electric bill or blow up your house, unplugging unused adapters\u2014or toggling them off on a switchable power strip\u2014is the safest habit.<sup><\/sup><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your brother-in-law is speaking from a strict trade-safety mindset!
