Most EVs come with a portable Level 1 EVSE (Electric Vehicle Supply Equipment) that plugs into a standard NEMA 5-15 outlet on one end and into the car on the other. No special installation is required.<\/p>\n<p>The trade-off is speed: Level 1 charging delivers approximately 1.2\u20131.4 kW, adding only <strong>3\u20135 miles of range per hour<\/strong>.<\/p>\n<figure style=\"margin:24px 0;text-align:center;\"><img decoding=\"async\" src=\"https:\/\/www.instaelectricians.com\/blog\/wp-content\/uploads\/[year]\/03\/EV-Charger-Installation.jpg\" alt=\"EV being charged at home\" style=\"max-width:100%;border-radius:8px;\" \/><figcaption style=\"color:#666;font-size:.9em;margin-top:6px;\">Level 1 charging uses a standard 120V outlet \u2014 the slowest but most universally accessible option<\/figcaption><\/figure>\n<h2 id=\"how_long_to_charge\">How Long Does It Take to Charge an EV on 120V?<\/h2>\n<p>Charging time depends on your battery capacity and how depleted it is. Some examples:<\/p>\n<ul>\n<li><strong>Nissan Leaf (40 kWh):<\/strong> ~28\u201333 hours for a full charge from empty<\/li>\n<li><strong>Chevy Bolt (65 kWh):<\/strong> ~45\u201355 hours from empty<\/li>\n<li><strong>Tesla Model 3 Standard Range (57.5 kWh):<\/strong> ~40\u201350 hours from empty<\/li>\n<li><strong>Ford F-150 Lightning (98 kWh):<\/strong> ~70+ hours from empty<\/li>\n<\/ul>\n<p>In practice, most EV owners don&#8217;t charge from empty. If you drive 30 miles per day and plug in each night, Level 1 can replace those 30 miles overnight (at ~4 miles\/hour, that&#8217;s about 7\u20138 hours of charging).<\/p>\n<h2 id=\"is_it_safe\">Is It Safe to Charge on a 120V Outlet?<\/h2>\n<p>Yes \u2014 with important conditions:<\/p>\n<ul>\n<li><strong>Use a dedicated outlet:<\/strong> A circuit shared with other high-draw devices (space heaters, refrigerators) can overload. Ideally, use a circuit dedicated to EV charging.<\/li>\n<li><strong>Never use an extension cord:<\/strong> Extension cords are not rated for continuous high-amperage loads and create a fire hazard. Always plug the EVSE directly into the wall outlet.<\/li>\n<li><strong>Check outlet condition:<\/strong> A loose or worn outlet creates heat and arcing risk under constant load. Have <a href=\"https:\/\/www.instaelectricians.com\/services\/ev-chargers-energy\">a licensed electrician<\/a> inspect or replace aging outlets used for EV charging.<\/li>\n<li><strong>Use a GFCI-protected outlet:<\/strong> In garages, GFCI protection is required by code and adds an extra layer of safety.<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><a href=\"tel:+18554360065\" class=\"ast-button ast-custom-button\">Call 855-436-0065 Now<\/a><\/p>\n<h2 id=\"when_upgrade\">When Should You Upgrade to Level 2?<\/h2>\n<p>Level 1 charging is practical if you drive fewer than 40 miles per day and charge overnight consistently.

This is sufficient for topping off a daily commute overnight but takes many hours to charge from empty.<\/p>\n<\/details>\n<details>\n<summary>Can I use an extension cord to charge my EV?<\/summary>\n<p>No. Extension cords are not rated for the continuous high-amperage draw of EV charging.
