It’s 9 p.m. You pull into the garage after a long day, plug the car into the ordinary outlet by the workbench, and go to bed. In the morning the app says you gained about 40 miles. For some households that’s all they ever need. For others, it’s the night they start shopping for a Level 2 charger. Here’s how to tell which one you are.

Level 1 charging uses a regular 120-volt outlet and adds about 5 miles of range per hour; Level 2 uses a 240-volt circuit and adds about 25 miles per hour, according to the Department of Energy’s Alternative Fuels Data Center. If you drive about 30 miles a day and park for 10 or more hours, Level 1 can be enough. Longer drives, bigger EVs or two cars usually call for Level 2.

Source: U.S. Department of Energy, Alternative Fuels Data Center (AFDC), “Electric Vehicle Charging Stations,” seen October 2026. The AFDC says a typical home Level 2 unit runs at up to 30 amps (7.2 kW) on a dedicated 40-amp circuit; many home chargers now go to 40 or 48 amps.

Why the “miles per hour” numbers don’t agree

Look at three U.S. government pages and you’ll find three answers. The AFDC and fueleconomy.gov say about 5 and 25 miles per hour. The EPA’s 2026 home charging guide says 3 to 5 miles per hour on Level 1 and 25 to 40 on Level 2. ENERGY STAR says 2 to 5 and 10 to 20. They’re all reasonable, because the real number depends on:

• The charger’s amperage. The EPA says Level 1 runs at 8 to 16 amps and Level 2 at 16 to 80 amps, with 30 to 40 amps most common.
• Your car’s onboard charger. The car limits how fast it accepts AC power. The 2026 Chevrolet Equinox EV, for example, is listed on fueleconomy.gov in versions with an 11 kW and a 19 kW charger. A 48-amp wall unit can’t push a car faster than its own limit.
• Your car’s efficiency. A small sedan gets more miles out of each kWh than a three-row SUV.
• Weather and battery level. fueleconomy.gov says charging losses vary with the vehicle, the charging system, the state of the battery and the weather.

Is Level 1 enough for you? Do the math

The Federal Highway Administration’s 2023 figures show light-duty vehicles averaged 11,026 miles a year, about 30 miles a day. Here’s roughly how long it takes to put back 30 or 50 miles in some 2026 EVs, using each car’s EPA electricity use from fueleconomy.gov (measured from the wall, so it includes charging losses):

2026 EV (EPA kWh per 100 mi)	kWh for 30 mi	Level 1, 12 A (1.44 kW)	Level 2, 7.2 kW	kWh for 50 mi	Level 1, 12 A	Level 2, 7.2 kW
Tesla Model 3 Premium RWD (24.6)	7.4	About 5 h	About 1 h	12.3	About 8.5 h	About 1.7 h
Tesla Model Y Long Range AWD (27.5)	8.2	About 5.7 h	About 1.1 h	13.8	About 9.5 h	About 1.9 h
Chevrolet Equinox EV FWD (31.1)	9.3	About 6.5 h	About 1.3 h	15.5	About 10.8 h	About 2.2 h
Ford Mustang Mach-E AWD (33.6)	10.1	About 7 h	About 1.4 h	16.8	About 11.7 h	About 2.3 h
Kia EV9 Long Range AWD (40)	12.0	About 8.3 h	About 1.7 h	20.0	About 13.9 h	About 2.8 h

These are our estimates: hours ≈ kWh needed ÷ charging power. We used 12 amps × 120 volts = 1.44 kW for Level 1 (a common setting within the EPA’s 8 to 16-amp range; the AFDC uses 1.9 kW) and the AFDC’s typical 7.2 kW for Level 2. Real times run a bit longer on cold nights and when the battery is nearly full.

The pattern is clear. At 30 miles a day, even a big SUV refills on Level 1 overnight if it’s parked for 10 hours or more. At 50 miles a day, the larger EVs need 11 to 14 hours on Level 1, which leaves little room for a long day. That matches fueleconomy.gov’s advice: consider Level 2 if your car has a large battery and you drive 50 or more miles a day on electricity.

Full charge times

You rarely charge from empty, but it shows the gap. The EPA’s label lists the time to charge an empty battery on 240-volt service: about 8 hours for the 2026 Model Y Long Range AWD, 9.5 hours for the Equinox EV FWD, 9.1 hours for the Ioniq 5 RWD and 10.7 hours for the EV9 Long Range AWD (fueleconomy.gov). The Department of Transportation says Level 1 can take 40 to 50+ hours to charge a battery-electric car from empty to 80%, while Level 2 does it in 4 to 10 hours.

Efficiency: Level 2 wastes a little less

Some energy is always lost turning AC from the wall into DC for the battery. A 2014 study in the journal Transportation Research Record (Sears and colleagues) measured both levels and found Level 2 was about 3% more efficient than Level 1 on average, with a bigger gap on very hot or cold days and on short charging sessions. On a typical year of driving that’s a few dollars to a few tens of dollars, not a reason on its own to upgrade.

What each one needs at home

Level 1: a standard 120-volt outlet within reach of the cable. Ideally the outlet isn’t shared with other big loads, because the car draws steady current for hours. Follow your car maker’s manual on outlets and extension cords, and if the plug or outlet gets warm, stop and call an electrician.

Level 2: a dedicated 240-volt circuit, either a NEMA 14-50 outlet for a plug-in charger (up to 40 amps) or hardwiring (the EPA says 48 amps and up usually must be hardwired). The breaker must be at least 125% of the charger’s current. That’s a job for a licensed electrician, with a permit where required, after a load calculation on your panel. The EPA says a home with at least 200-amp service and two free breaker slots likely has room. See EV charger installation cost for prices and panel-upgrade options.

Popular Level 2 chargers

Prices change often. The prices below are what we saw at the maker or a major retailer in October 2026; check the current price before you buy.

Charger	Max current	Install	Cable	About price
Grizzl-E Classic 40A	40 A	14-50 or 6-50 plug	25 ft	$299.99
ChargePoint Home Flex	50 A hardwired	Plug or hardwired	23 ft	$549 to $599

Emporia Classic	48 A	Plug or hardwired	25 ft	From $449

The Grizzl-E Classic is the no-frills option: a metal case, no Wi-Fi, and a dial for the current. The ChargePoint, Wallbox and Emporia chargers add apps for scheduling and tracking, which helps if your utility has cheaper off-peak hours (many cars can schedule charging too). Whichever you choose, buy one listed by a recognized lab such as UL or ETL; ENERGY STAR says its certified chargers all have that testing.

Which should you choose?

• Stay on Level 1 if you have a plug-in hybrid (the EPA calls Level 1 best for short commutes and PHEVs), drive under about 30 to 40 miles most days, and park for 10+ hours at night.
• Get Level 2 if you drive 50+ miles a day, have a large battery or two EVs, work shifts that leave short parking windows, or want to charge only in the cheapest off-peak hours.
• Try Level 1 first for a few weeks. It costs nothing, and your car’s app will show whether you keep up. If you don’t, you’ll know what you need.
• Renters: the EPA notes that “right-to-charge” laws in many states may let you install a charger if you have an assigned parking space. Ask your landlord.

Level 1 vs Level 2 questions

How many miles does Level 1 charging add overnight?

The Department of Energy says 8 hours at 120 volts adds about 40 miles for a mid-size EV, roughly 5 miles per hour. Over 10 to 12 hours that’s about 50 to 60 miles. Big SUVs and trucks get fewer miles per hour because they use more energy per mile; cold weather also slows it.

Is Level 2 charging worth it?

For most full EV owners, yes, especially if you drive 50+ miles a day or have two EVs. It refills a typical day’s driving in one to three hours, so you can charge only in cheap off-peak hours. If you drive little and have a plug-in hybrid, Level 1 may be all you need.

Can I use a dryer outlet for Level 2 charging?

A dryer outlet is 240 volts, but it is often a 30-amp circuit with a different plug, and the dryer needs it too. Charging limits are set by the circuit, not just the plug. Ask a licensed electrician; options include a circuit-sharing device or a new dedicated circuit, with a permit where required.

Does Level 1 or Level 2 charging hurt the battery?

Both are slow, gentle AC charging compared with DC fast charging, and your car’s battery management system controls the rate either way. Follow your car maker’s guidance in the owner’s manual or app on the everyday charge limit; it varies by car and battery type.

Is Level 2 cheaper per mile than Level 1?

Slightly. A 2014 study found Level 2 about 3% more efficient on average, so you pay for a little less wasted energy. The bigger savings come from charging at off-peak rates, which is easier with Level 2’s shorter charging times. The installation cost usually outweighs the efficiency gain.

What amperage Level 2 charger do I need?

For most homes, 32 to 40 amps is plenty; the EPA says 30 to 40 amps is most common. A 40-amp charger can plug into a NEMA 14-50 outlet on a 50-amp circuit. Go to 48 amps only if your car’s onboard charger can use it and your panel has room.
