Charge at Home / The basics

Can you charge an EV from a regular outlet?

Yes. Expect about 4.2 miles of range an hour, and give the cord a circuit of its own.

A standard 120-volt household outlet on a 15-amp circuit can charge any EV that comes with a Level 1 cordset. Most cordsets draw 12 amps, which is 1.44 kW, about 4.2 miles of range for every hour plugged in, or about 42 miles over a ten-hour night.

Range figures assume a car that uses 30 kWh per 100 miles and loses 12 percent of the energy between the wall and the battery. Your car's figure is on its fueleconomy.gov label; the calculator takes yours.

Make it safe before you make it routine

The cord will draw its full current for hours. That is a different job from a lamp or a phone charger.

  • Use a dedicated circuit. The Department of Energy describes Level 1 charging as plugging into a power outlet on a dedicated branch circuit. If the garage outlet also feeds a freezer or a shop light, the breaker can trip mid-charge, or the circuit can run near its limit for hours.
  • No extension cords, no adapters. Plug the cordset straight into the receptacle.
  • Check the outlet. A worn receptacle that holds the plug loosely heats up under a long load. If the plug or the cover is warm to the touch, stop and have it replaced.

When a 20-amp circuit helps

Some cordsets can draw 16 amps on a 20-amp circuit, which raises the rate to about 5.6 miles an hour. Only use the higher setting when you know the circuit is 20 amps; the breaker size guide explains the 80 percent rule behind those numbers.

If a night of Level 1 does not cover your driving, read Level 1 vs. Level 2.
