Spark Cashback
Level 1 vs Level 2 home EV charger
October 8, 2026 · by Soneil Spark
Level 1 uses a regular 120V household outlet. Level 2 uses a 240V circuit, like a dryer, and adds range several times faster. For most people who park at home overnight, a Level 2 home charger is the better fit.
The short comparison
| Level 1 | Level 2 | |
|---|---|---|
| Power Supply | 120V outlet | 240V circuit |
| Speed | Slowest. Often a few km of range per hour | Several times faster. Usually a full overnight charge |
| Install | Usually none, plug into an outlet | 240V outlet or hardwired circuit |
| Best For | Short daily drives, backup | Daily commuting, larger batteries |
Where a 40A Level 2 charger fits
A 40A charger on 240V can deliver up to about 9.6 kW, which is why it can refill most EVs overnight. It needs a circuit sized for it, so have an electrician confirm your panel and wiring first. Your car also sets a maximum charge speed, so a faster charger will not exceed what the car accepts.
Can I earn cash back on a home charger?

Quick answers
Is a Level 2 charger worth it for home use?
If you drive daily and park at home, usually yes. It is far faster than a standard 120V outlet and can refill most EVs overnight.
Do I need an electrician for a Level 2 charger?
A plug-in model on an existing 240V outlet may not need one. A hardwired install does. An electrician can confirm your panel capacity.
