Level 1 EV Chargers

What is a Level 1 EV charger?

A Level 1 EV charger is the most basic form of electric vehicle charging. It uses a standard 110–120V household outlet and supplies AC power to the vehicle’s onboard charger.

Most electric vehicles include a Level 1 charging cable with purchase, allowing drivers to charge without additional equipment or electrical upgrades.

How fast does a Level 1 EV charger charge an electric vehicle?

Level 1 chargers provide the slowest charging speeds among EV charger types. On average, they add approximately 3–6 miles of driving range per hour, depending on vehicle efficiency and power draw.

How long does it take to charge with a Level 1 EV charger?

Charging time depends on battery size and starting charge level. For many EVs, fully charging from a low battery using Level 1 can take 24 to 48 hours or more.

This makes Level 1 charging best suited for overnight or extended parking periods.

How many amps does a Level 1 EV charger use?

Most Level 1 EV chargers draw between 12 and 16 amps on a 120V circuit. To reduce the risk of overloading household wiring, many vehicles default to a lower amperage unless manually adjusted.

What is the installation cost of a Level 1 EV charger?

In most cases, Level 1 charging requires no installation cost, since it uses an existing household outlet.

However, if the outlet is old, damaged, or shared with other heavy loads, an electrician may recommend upgrading or adding a dedicated circuit.

What’s the difference between Level 1 and Level 2 EV chargers?

The primary difference is charging speed and electrical supply:

• Level 1: 120V, slow charging, no special installation
• Level 2: 240V, much faster charging, requires installation

Level 2 chargers are generally preferred for drivers with higher daily mileage or limited charging time.

How to install a Level 1 EV charger at home?

Installing a Level 1 charger usually involves plugging the charging cable into a standard wall outlet near where the vehicle is parked.

For safety and reliability, the outlet should be:

• In good condition
• Properly grounded
• Not shared with other high-power appliances

Are there safety guidelines for using a Level 1 EV charger at home?

Yes. Basic safety practices include:

• Avoid using extension cords unless explicitly approved by the manufacturer
• Inspect the outlet and plug regularly for heat or damage
• Keep connections dry and protected from weather
• Stop charging if you notice burning smells or excessive heat

Are Level 1 EV chargers worth it for daily driving?

Level 1 charging can be sufficient for drivers with short daily commutes who can charge overnight every day.

If you regularly drive long distances or need faster turnaround, upgrading to Level 2 charging is often more practical.

How to maintain and troubleshoot a Level 1 EV charger?

Level 1 chargers require minimal maintenance. Recommended practices include:

• Keeping the cable clean and free from sharp bends
• Checking plugs and connectors for wear
• Ensuring the outlet remains secure and undamaged

If charging stops unexpectedly, check the outlet, breaker, and vehicle settings before contacting the manufacturer or a qualified electrician.
