Comparison
Level 1 vs Level 2 Charging: Which One Do You Need?
The answer is in your daily miles and the hours the car sits at home, not in the brochure.
Written by HyreElectrical Research Desk Primary-source research and fact checking
The short answer
Level 1 vs level 2 charging is a question of miles per night.
Level 1 uses a 120 V plug and adds about 5 miles of range per hour of charging; Level 2 uses 240 V at home and adds about 25 miles per hour, according to the U.S. Department of Energy.
If you drive 30 miles a day and the car is parked 10 hours, Level 1 can keep up. If you drive more, or park for less time, Level 2 is usually the answer. Run your numbers in the EV charger selector.
Level 1 and Level 2, side by side
| Level 1 | Level 2 | |
|---|---|---|
| Voltage | 120 V AC plug | 240 V at home (208 V in many commercial buildings) |
| Range added per hour (DOE) | About 5 miles at 1.9 kW | About 25 miles; 2.9 to 19.2 kW |
| What it plugs into | An ordinary outlet, ideally on its own circuit | A 240 V outlet or a hardwired circuit |
| Electrician needed | Usually not, if a suitable outlet exists | Yes, for the new circuit, usually with a permit |
| Panel impact | Small | A continuous load; may trigger a load calculation |

The one calculation that decides it
Miles you drive on a normal day ÷ hours parked at home. If the answer is under about 5 miles per hour, Level 1 covers it on DOE’s figure. Above that, you are borrowing from tomorrow. Weekends and cold weather change the answer, so allow headroom.
Level 2 is a continuous load. NEC 625.42 treats EV charging as continuous, so the circuit is sized at 125% of the charging current. A 40 A charger needs a 50 A circuit. Check whether your panel can carry it with the EV readiness tool.
A smaller Level 2 is allowed. Many chargers can be set to a lower current, which may avoid a service upgrade. See load management.
What drives the price difference
We publish no figures. Level 1 often costs nothing beyond the cord that ships with the car.
Level 2 cost is driven by the charger, the distance from the panel to the parking spot, whether the panel has room and capacity, and the permit.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of October 26, 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
