Level 1 vs Level 2 EV Chargers: Which Is Right for Your Home?

Electric vehicles continue to grow in popularity across Colorado, and with that comes the need for reliable home charging. One of the first decisions EV owners face is choosing between Level 1 and Level 2 EV chargers. Both can get the job done, but they offer very different experiences when it comes to speed, convenience, and long-term value.

Before installing a charger at home, it is important to understand the differences between EV charger levels and how they affect your daily routine.

What Is a Level 1 EV Charger?

Level 1 charging uses a standard 120-volt outlet — the same kind found throughout most homes. Every EV comes with a Level 1 charging cord that plugs directly into the wall.
This option is:

• Simple to use
• Requires no special installation
• Best for low-mileage drivers or overnight charging

However, Level 1 charging is the slowest option. It typically adds 3 to 5 miles of range per hour, which means a full charge can take 20 hours or more, depending on your vehicle.

What Is a Level 2 EV Charger?

Level 2 chargers use a 240-volt circuit, similar to what a dryer or oven uses. These systems require professional installation but offer a much faster charge.
With Level 2 charging, you can expect:

• 25 to 30 miles of range per hour
• A full charge in 4 to 8 hours, depending on battery size
• Smart features like timers, load management, or mobile apps

Level 2 chargers are ideal for daily drivers, busy households, or anyone looking to reduce wait times and improve convenience.

Key Differences Between Level 1 and Level 2

How to Decide Which EV Charger Level Is Right for Your Home

Here are a few factors to consider when deciding:

• Daily driving habits: If you drive long distances or multiple times per day, a Level 2 charger provides the speed and consistency you need
• Household usage: More than one EV or frequent back-to-back trips can quickly overwhelm a Level 1 system.
• Available time for charging: Level 1 charging may be enough if you can leave your car plugged in overnight and do not rely on it for heavy use.
• Home electrical panel capacity: A licensed electrician can help you determine if your panel can support a Level 2 charger or needs an upgrade.

Why Professional Installation Matters

While Level 1 chargers are simple, installing a Level 2 charger involves more than plugging into the wall. It requires:

• Load calculations to avoid overload
• A new 240-volt circuit with the correct amperage
• Proper permitting and code compliance
• Weatherproof installation if mounted outdoors
