See miles per night for popular EVs." url: https://evchargecosts.com/guides/charging-an-ev-on-a-regular-outlet/ updated: 2026-10-26 --- # Can You Charge an EV on a Regular 120 V Outlet? Yes. A standard 15 A household outlet supports a 12 A charge (1.44 kW), which adds about **4.3 miles of range per hour** to a 33.5 kWh/100 mi EV, or roughly **52 miles over a 12-hour night**. That covers an average 37-mile day for many drivers. By [EV Charge Cost Editorial Team](https://evchargecosts.com/about/). Published September 28, 2026, updated October 26, 2026. Every EV can charge from an ordinary 120 V outlet using a Level 1 charging cord, and many cars come with one. It is slow, but slow is often fine: the car only needs to put back what you drove today, and it usually sits parked for many hours. ## How much range a night adds An ordinary NEMA 5-15 outlet is on a 15 A circuit. Because charging is a continuous load, it may draw 80% of that, 12 A, which is 120 V × 12 A = 1.44 kW. The table shows miles added in an illustrative 10- and 12-hour overnight session for popular models, using each model's representative EPA rating. **Range added on a 120 V, 12 A outlet (1.44 kW)** | Model | kWh/100 mi | Miles per hour | Miles in 10 h | Miles in 12 h | | --- | --- | --- | --- | --- | | [Tesla Model Y](https://evchargecosts.com/vehicles/tesla-model-y/) | 26.9 | 5.4 | 54 | 64 | | [Tesla Model 3](https://evchargecosts.com/vehicles/tesla-model-3/) | 26.4 | 5.5 | 55 | 66 | | [Tesla Model S](https://evchargecosts.com/vehicles/tesla-model-s/) | 32.5 | 4.4 | 44 | 53 | | [Tesla Model X](https://evchargecosts.com/vehicles/tesla-model-x/) | 34.2 | 4.2 | 42 | 50 | | [Tesla Cybertruck](https://evchargecosts.com/vehicles/tesla-cybertruck/) | 42.9 | 3.4 | 34 | 40 | | [Chevrolet Equinox EV](https://evchargecosts.com/vehicles/chevrolet-equinox-ev/) | 32.6 | 4.4 | 44 | 53 | | [Chevrolet Blazer EV](https://evchargecosts.com/vehicles/chevrolet-blazer-ev/) | 35.6 | 4.0 | 40 | 48 | | [Chevrolet Silverado EV](https://evchargecosts.com/vehicles/chevrolet-silverado-ev/) | 49.6 | 2.9 | 29 | 35 | A 12-hour session delivers 17.3 kWh from the wall. At the U.S. average price of 18.16¢/kWh (August 2026), that costs about $3.14. The price per kWh is the same as on Level 2. ## Who it works for - **Short and medium commutes.** Replacing 37 miles takes about 8 h 36 min for a 33.5 kWh/100 mi EV. - **Efficient cars.** The [Tesla Model 3](https://evchargecosts.com/vehicles/tesla-model-3/) gains 5.5 miles per hour; a large vehicle like the [Chevrolet Silverado EV](https://evchargecosts.com/vehicles/chevrolet-silverado-ev/) gains only 2.9. - **Plug-in hybrids**, whose small batteries often refill completely overnight. - **Second cars** and anyone with occasional access to faster charging for long days. ## Where it falls short - **Long daily drives.** At 4 miles an hour, a 100-mile day needs about 23 h 16 min. - **Short off-peak windows.** If cheap power lasts only a few hours, Level 1 cannot fit much into it. - **Cold weather.** Some of the modest power goes to keeping the battery warm, so fewer miles are added. - **Recovering from a road trip.** Refilling a mostly empty battery can take several days. ## Try it for a week before buying anything The easiest way to know whether Level 1 is enough is to live with it. Plug in every evening for a week of normal driving and watch the state of charge each morning. If the battery climbs back to your usual level most mornings, you may not need a 240 V circuit at all. - Note your longest day of the week and whether the car caught up by the next morning. - Check how many hours the car was actually plugged in; late arrivals and early departures shrink the window. - Repeat in the coldest month if you can, since winter mornings are the hardest test. ## What about a 20 A circuit? A 120 V, 20 A circuit allows 16 A continuous: 1.92 kW, about 6 miles per hour. Only use that setting if your charging cord supports it and the outlet and circuit are rated for it; otherwise stay at 12 A. ## Safety checklist for Level 1 - Use the cord supplied or approved by the car maker and follow its instructions. - Plug directly into the wall. Do not use household extension cords or plug adapters; see [extension cords and EV charging](https://evchargecosts.com/guides/extension-cords-and-ev-charging/). - Prefer an outlet with nothing else heavy on the same circuit, such as a freezer or space heater. - Check the plug after a long session. If the plug or outlet feels hot, looks discolored, or the breaker trips, stop and have a licensed electrician inspect it. - Older or worn outlets are a common weak point; an electrician can replace one with a heavy-duty receptacle or add a dedicated circuit, with a permit where required. If Level 1 does not keep up, compare it with 240 V in [Level 1 vs Level 2 charging](https://evchargecosts.com/guides/level-1-vs-level-2-charging/), or see what your state's electricity costs on the [state pages](https://evchargecosts.com/states/). ## Run your own numbers - [Charging cost calculator](https://evchargecosts.com/) - [EV vs gas calculator](https://evchargecosts.com/ev-vs-gas/) - [Charging time calculator](https://evchargecosts.com/charging-time/) - [Cost in your state](https://evchargecosts.com/states/) - [How we calculate](https://evchargecosts.com/methodology/) ## Related guides - [Level 1 vs Level 2 Charging: Speed and Cost](https://evchargecosts.com/guides/level-1-vs-level-2-charging/) - [How Many Amps Do You Need for a Home EV Charger?](https://evchargecosts.com/guides/how-many-amps-for-ev-charger/) - [NEMA 14-50 Outlet vs Hardwired EV Charger](https://evchargecosts.com/guides/nema-14-50-vs-hardwired-ev-charger/) - [Can My Electrical Panel Handle an EV Charger?](https://evchargecosts.com/guides/can-my-electrical-panel-handle-an-ev-charger/) - [Why Your EV Charges Slower Than the Charger: Onboard Limits](https://evchargecosts.com/guides/onboard-charger-limit-explained/) - [Can You Use an Extension Cord to Charge an EV?](https://evchargecosts.com/guides/extension-cords-and-ev-charging/) [All 59 guides](https://evchargecosts.com/guides/) ## Questions people ask ### How many miles does an EV get from charging overnight on 120 V? About 43 to 52 miles over 10 to 12 hours for a 33.5 kWh/100 mi EV at 12 A. Less efficient trucks and large SUVs get noticeably fewer. ### Is Level 1 charging bad for the battery? No. Slow AC charging is gentle on the battery. Its only drawbacks are speed and slightly higher conversion losses than Level 2. --- Source page: https://evchargecosts.com/guides/charging-an-ev-on-a-regular-outlet/ Data: EIA (electricity August 2026, gasoline 2026-10-19), EPA fueleconomy.gov.
