Level 1 vs. Level 2: which do you need?
Level 2 is faster, but faster only matters if Level 1 can't keep up with how far you drive. For many people with an outlet near their parking spot, it can.
- Level 1
- Standard 120V outlet. About 5 miles of range per hour of charging.
- Level 2
- 240V (typical in homes) or 208V (typical in commercial and many condo buildings). About 25 miles of range per hour.

The simple test
Multiply 5 miles by the hours your car sits parked at home overnight. Ten hours plugged in gives about 50 miles. If you usually drive less than that in a day, Level 1 can keep up, with the occasional longer trip covered by a weekend top-up or a public charger.
When Level 2 is worth it
- You regularly drive more than Level 1 can replace overnight
- Two EVs share one parking spot or one outlet
- You want a full battery quickly after long trips
- Your parking time at home is short (shift work, for example)
Why this matters in a condo or rental
Asking to use an existing outlet is a far smaller request than asking for a new 240V circuit. If Level 1 fits your driving, start there. Read the charging guide for your situation to see which fits.
