Phase 1
What Level 1 and Level 2 Actually Mean
Level 1 charging uses the cable that comes with your EV, plugged into a standard 120V household outlet. No electrical work required, but it is slow, typically adding only 3 to 5 miles of range per hour. A full charge from a low battery can take well over 24 hours.
Level 2 charging runs on a dedicated 240V circuit, the same voltage as an electric dryer or range. On a 60A circuit, a Level 2 charger delivers up to 48A and 11.5kW, adding up to 44 miles of range per hour, enough for a full overnight charge on nearly any EV.
Phase 2
When Level 1 Is Actually Enough
In practice, Level 1 works for drivers who cover short daily distances and plug in every night. If your commute is under 30 miles round trip, a standard outlet can keep pace over an 8 to 10 hour overnight window. Plug-in hybrids with smaller batteries are also a common fit, since they need far less range replenished per night.
Phase 3
Why Most Homeowners Choose Level 2
Most EV owners drive more than a short commute, or want the flexibility to skip a night without worrying about range. It also matters if you added an EV after your household already has one, since two vehicles sharing a Level 1 outlet rarely keeps up. Because of that, a Level 2 charger closes the gap and finishes a full charge in a few hours instead of a full day.
That installation requires 240V circuitry, which is regulated under Washington electrical code (RCW 19.28) and must be done by a licensed electrician. Solphos handles permitting, wiring, and inspection as part of every install.

Common Questions
Level 1 vs Level 2 charging, what’s the difference?
In short, Level 1 uses a standard 120V outlet and adds 3 to 5 miles of range per hour, while Level 2 uses a dedicated 240V circuit and adds up to 44 miles of range per hour, fast enough for a full overnight charge.
Can I just use the charging cable that came with my EV?
Yes, that cable gives you Level 1 charging from any standard outlet. It works, but it is slow enough that most owners upgrade to Level 2 once their driving habits or household EV count outgrow it.
Do I need an electrician for Level 2 charging?
Yes, because Level 2 charging requires a dedicated 240V circuit, which is regulated under Washington electrical code and must be installed by a licensed electrician, not done as a DIY project.
How much faster is Level 2 than Level 1?
In most home installations, Level 2 is roughly 8 to 10 times faster than Level 1, turning a full charge that takes over a day into one that takes a few hours.
Is Level 2 worth it if I don’t drive much?
Not always. If your daily driving is short and you always plug in overnight, Level 1 may keep up fine. We can help you figure out which level actually fits your situation. Get My Free Quote →
