Level 1 vs Level 2 Home Charging: Cost, Speed & What to Install
The speed difference is the whole story
Level 1 is a standard 120V outlet: 3-5 miles of range per hour — an overnight charge adds 40-50 miles. Level 2 runs on 240V (a dryer-style circuit): 20-40 miles per hour, filling any EV overnight from near-empty.
Electricity cost per kWh is identical on both — the meter doesn't care about speed. Level 2 is marginally more efficient (fewer hours of conversion losses), but the real difference is convenience, not the bill.
What Level 2 costs to install
Hardware runs $300-700 for a quality unit; installation ranges from ~$300 (panel near garage) to $1,500+ (long wire runs, panel upgrades). Many utilities and some states offer rebates that cover a meaningful chunk — check your utility's website before buying anything.
Rule of thumb: if you drive under 40 miles a day, Level 1 genuinely suffices. Above that, or with two EVs, Level 2 pays for itself in flexibility.
