Level 1 vs Level 2 EV Charging: Which Do You Actually Need?
Confused about Level 1 vs Level 2 charging? You're not alone. One uses a regular 120V outlet, the other needs a 240V circuit — but the real difference is 5x-10x faster charging. Here's everything you need to know to choose the right one.
What Is Level 1 Charging?
Level 1 charging uses a standard 120-volt household outlet (NEMA 5-15) — the same one you plug your phone or laptop into. Every EV comes with a Level 1 charging cable in the trunk.
Speed: Level 1 adds about 3-5 miles of range per hour. That's roughly 40-50 miles overnight (10-12 hours). For a 60 kWh battery (like the Chevy Bolt), a full charge from empty takes about 50+ hours.
Power draw: 1.2-1.4 kW (12A at 120V). This is less than a space heater.
The main advantage? Zero installation cost. If you have an outdoor outlet near your parking spot, you can start charging today for free. No electrician, no permits, no hardware purchase.
What Is Level 2 Charging?
Level 2 charging uses a 240-volt circuit — the same voltage as your dryer or oven. You need a dedicated Level 2 charging station (EVSE) and typically a NEMA 14-50 outlet or hardwired connection.
Speed: Level 2 adds 25-30 miles of range per hour at 40A, or up to 37 miles/hour at 48A. Most EVs charge from empty to full in 6-10 hours — easily overnight.
Power draw: 3.8-11.5 kW depending on amperage (16A to 48A at 240V).
Cost: A good Level 2 charger costs $159-$300 for budget models or $300-$700 for premium models. Installation runs $200-800 if you need a new 240V circuit. Use our Charging Cost Calculator to see your monthly costs.
Level 1 vs Level 2: Side-by-Side Comparison
| Feature | Level 1 | Level 2 |
|---|---|---|
| Voltage | 120V | 240V |
| Amperage | 12-16A | 16-48A |
| Power | 1.2-1.9 kW | 3.8-11.5 kW |
| Range per hour | 3-5 miles | 12-37 miles |
| Full charge time (60 kWh) | 40-50 hours | 5-10 hours |
| Charger cost | $0 (included with EV) | $159-$700 |
| Installation cost | $0 | $0-$800 |
| Monthly electricity | ~$30-50 | ~$30-50 (same energy, just faster) |
| Best for | PHEVs, low-mileage drivers | Most EV owners |
Key insight: Level 1 and Level 2 cost the same amount of electricity for the same charge — Level 2 just does it faster. The only extra cost is the charger hardware and installation. Use our Charging Time Calculator to compare speeds for your specific vehicle.
When Level 1 Charging Is Enough
Level 1 can work well if:
- You drive less than 40 miles/day — Level 1 recovers this overnight.
- You have a plug-in hybrid (PHEV) — Smaller batteries (8-18 kWh) charge in 5-8 hours on Level 1.
- You have access to workplace charging — 8 hours at work + overnight at home = plenty.
- You're renting and can't install 240V — Level 1 is better than nothing.
- You want zero upfront investment — Try Level 1 first, upgrade later if needed.
According to the U.S. Department of Energy, the average American drives about 37 miles per day — which Level 1 can technically handle. But any variation in routine (road trips, errands, cold weather) quickly exposes its limits.
When You Need Level 2
Upgrade to Level 2 if:
- You drive more than 40 miles/day — Level 1 can't keep up.
- You have a full battery EV (not PHEV) — 60-100 kWh batteries are too large for Level 1.
- You need reliability — Never worry about starting the day with a full battery.
- Cold climate — EVs use more energy in cold weather AND Level 1 charges slower.
- You want smart features — Scheduling, energy monitoring, app control.
Our recommendation: If you own a full BEV (not a plug-in hybrid), Level 2 is worth the investment. A budget charger like the Emporia Smart at $159 with a simple NEMA 14-50 outlet installation ($200-400) pays for itself in convenience within weeks. See our top Level 2 charger picks.

Frequently Asked Questions
Can I use Level 1 charging every day?
Yes, but only if you drive less than 40 miles per day. Level 1 adds 3-5 miles of range per hour, which means about 40-50 miles overnight. If you regularly drive more than this, you'll slowly drain your battery over the week. Check your daily needs with our Charging Time Calculator.
Does Level 2 charging cost more electricity than Level 1?
No. Both Level 1 and Level 2 use the same amount of electricity (kWh) for the same charge. Level 2 is just faster. Your monthly electric bill will be roughly the same regardless of charging level. The only extra cost is the charger hardware ($159+) and possible installation ($200-800). Use our Charging Cost Calculator to estimate your monthly cost.
Can I install a Level 2 charger myself?
If you already have a NEMA 14-50 outlet (like for a dryer or RV), you can plug in a Level 2 charger yourself — no electrician needed. If you need a new 240V circuit installed, hire a licensed electrician. It typically costs $200-500 for a straightforward installation. See our recommended chargers that come with NEMA 14-50 plugs.
Is Level 2 charging bad for my EV battery?
No. Level 2 charging (up to 19.2 kW) is perfectly safe for daily use. EV batteries are designed for Level 2 speeds. Only frequent DC fast charging (50-250 kW) can cause slightly faster battery degradation over time. Level 2 at home is the gentlest way to charge besides Level 1.
What about Level 3 / DC fast charging?
DC fast charging (Level 3) uses 50-350 kW and can charge most EVs to 80% in 20-45 minutes. It's great for road trips but not practical for home use — the equipment costs $20,000+ and requires commercial-grade electrical service. For home charging, Level 2 is the sweet spot.
