Questions  about level 2 EV chargers?

The average price of one kilowatt-hour varies based on your location, electricity provider, and the time of day you charge. Your Generac charger allows you to schedule charging during off-peak hours, potentially saving you money per kilowatt-hour. To estimate the cost to charge your EV, multiply the battery capacity needed to reach your desired charge level by the electricity rate in your area. For example, charging a 60 kWh battery from 20% to 80% at $0.13 per kWh costs approximately $4.68.

It all depends on the battery capacity of your electric vehicle, and the type of charger you’re using, plus the type of power you’re pulling from the grid. You can only rely on the speed of the lowest number from that equation. Here’s how it works together:  

Level 1 chargers typically come with an electric vehicle at the time of purchase and are plugged into standard 120-volt wall outlet – no installation required. A level 2 charger is installed into a wall to tap into a 240-volt source and can charge your vehicle significantly faster than a level 1 charger.

The main difference is how fast they charge your car! The 40-amp charger adds about 25-30 miles of range per hour, while the 48-amp charger adds about 30-37 miles of range per hour, so you can get back on the road even quicker

Generac EV chargers are compatible with all electric vehicles using the standard J1772 connector. For vehicles that use the NACS (North American Charging Standard) connector, such as Tesla, you can use the SAE J1772 to NACS adapter that comes with the car to connect to the Generac charger.

We offer a three-year limited warranty on our EV chargers, covering any defects in material and workmanship under normal use. If you experience any issues within this period that aren't caused by misuse, improper installation, or other exclusions, we'll repair, replace, or refund the purchase price of the equipment. To claim warranty service, please contact us for shipping instructions and provide your proof of purchase.

Level 2 EV chargers require 240-volt outlets. This increased power is what enables the faster charging of your EV. It's important to ensure your home’s electrical system can handle the additional load of a 240-volt outlet and EV charger. You may need to consult a licensed electrician for installation.

The total cost for installing a level 2 EV charger at home is different for everyone. But on average, installation costs range from $700-$2,000. Learn more on our installation page.

Different localities have different permitting requirements. When you work with a local Generac installer, they can help guide you through what’s necessary. request a quote to be matched with an expert near you.

Since most level 2 EV chargers require licensed electrical work in order to be installed correctly, we recommend you request a quote for a Generac charger plus installation, rather than attempting it yourself


Yes! There are currently federal tax credits for 30% of the item’s cost up to $1,000 when a charger is installed at your primary residence. Get details from the Department of Energy.

There are AC and DC type chargers. AC plugs include level 1 and level 2 chargers. DC chargers include CCSand DC fast chargers.  

A CCS charger has an enhanced version of a type 2 plug, with two additional power contacts. These additional contacts are what allow it to charge an EV even faster, up to 350 kW. 

The answer to this question requires some understanding of electrical basics. First, it’s important to know that power from the electric grid is always alternating current (AC). But, the battery in your EV has to store power as direct current (DC). To convert AC to DC, your vehicle has an “onboard charger” which does the same job as a typical charging cord – converts AC from the wall outlet to DC power that can be used by a battery-powered device.  
 
Now, if you use a DC charger, it feeds power directly into the EV battery, without requiring the onboard charger to convert it, making the charging time a whole lot faster.
