A Guide to Level 1 vs. Level 2 Charging

For new electric vehicle (EV) owners, the idea of charging your car instead of refueling at gas stations takes some getting used to. In the world of EVs, the familiar routine of pulling up to a gas station, inserting a nozzle, and waiting for a full tank is a thing of the past. Electric vehicles are a different animal and one can't simply drive to a charging station, plug in any nozzle, and call it a day.

When it comes to EV charging, one of the most crucial aspects is understanding charging levels. Just like the three types of gasoline, there are also three levels of charging that act as their counterpart, with Level 1 and Level 2 as the most common.

Levels of EV Charging

Before diving into the specifics of Level 1 and Level 2 charging, it's essential to understand the broader context of EV charging levels:

Level 1 Charging

Think of Level 1 EV charging as your regular fuel. It is the most basic and widely accessible form of EV charging. As with your regular low-octane fuel, a Level 1 EV charger is the least powerful of the three as it plugs into a standard 120-volt household electrical outlet. While slow, it can be convenient for overnight home charging. It is often referred to as "trickle charging" due to its slower rate of energy transfer.

Level 2 Charging

Level 2 EV chargers are like your midgrade fuel pumps. As with mid-range octane fuel, Level 2 charging offers a significant increase in power compared to Level 1. It utilizes a 240-volt electrical supply, similar to what your home uses for large appliances like electric stoves or dishwashers. Level 2 chargers are typically installed using dedicated charging equipment and can be found in various public charging stations, workplaces, and residential settings. This level of charging is commonly used for daily charging needs and is much more efficient than Level 1.

DC Fast Charging

DC fast chargers are the premium gasoline pumps in the EV world. As with the highest-octane fuel, these chargers offer the most power output of the three, giving the fastest charging speed suitable for short top-ups on the road. As the name suggests, it supplies direct current (DC) straight to the EV battery pack, providing a substantial charge in a relatively short amount of time. However, DC Fast Charging stations are less common and are typically found along highways and major travel routes.

DC fast chargers stand out as the premium gasoline pumps in the EV world, delivering the fastest charging speeds, perfect for quick top-ups on the road.

Main Differences Between Level 1 and Level 2 Charging

Now that we've covered the basics, let's delve into the key differences between the two levels you would encounter most often: Level 1 and Level 2.

Charging Time

Level 1 Charging: Level 1 charging is slow, typically delivering about 3 to 5 miles of range per hour of charging. This makes it suitable for overnight charging when you have ample time to replenish your EV battery.

Level 2 Charging: Level 2 charging is considerably faster, providing charging speeds between 12 and 80 miles of range per hour. This makes it more suitable for daily charging needs, such as topping off your battery while at work or during a shopping trip.


Level 1 Charging: Level 1 chargers require no special installation beyond having access to a standard household electrical outlet. Most EVs come with a Level 1 charger that you can plug into any standard 120-volt outlet.

Level 2 Charging: Level 2 chargers can either be directly plugged into an existing 240-volt outlet or be hardwired into your home's electrical panel. Portable Level 2 chargers are now widely available in place of dedicated charging stations. However, if you opt for a fixed charger, installation may involve upgrades to your electrical panel, which would require the services of an electrician.


Level 1 Charging: Level 1 charging is the most cost-effective option since it utilizes existing household electrical infrastructure. The only expense may be the purchase of an adapter or extension cord if your outlet is not conveniently located.

Level 2 Charging: As previously mentioned, with Level 2 chargers, you have the option of either plugging directly into a 240V outlet or having dedicated charging equipment installed. Hardwiring a Level 2 charger is more expensive due to the possibility of upgrades to the existing electrical service, but it can range from a few hundred to a few thousand dollars, depending on factors like the distance from your electrical panel and the charger's features.


Level 1 Charging: Level 1 charging is highly portable. Since it uses standard outlets, you can charge your EV wherever there's an available 120-volt socket. This makes it suitable for occasional or emergency charging when away from home.

Level 2 Charging: Level 2 charging is less mobile. While there are portable Level 2 chargers, 240-volt outlets are not as widely available as 120-volt ones. As for hardwired charging stations, once installed, they are typically fixed in one location, making them less suitable for on-the-go charging. However, the convenience of faster charging at home or designated locations often outweighs this limitation.

When considering the mobility and cost of EV charging options, it's essential to weigh the convenience of Level 1 charging's portability against the relatively fixed nature of Level 2 charging stations. Additionally, explore the potential costs associated with installing electric car chargers to make an informed decision that aligns with your charging needs and lifestyle.

Which type of charger do you need for your electric vehicle?

Choosing the right charger for your electric vehicle depends on your charging requirements, daily driving habits, and budget. Here are some factors to consider:

  • Daily Commute: If you have a relatively short daily commute and can charge overnight, Level 1 charging may be sufficient.

  • Longer Commutes: If your daily driving distance is longer or you want faster charging for convenience, a Level 2 EV charger is a better choice.

  • Installation: Consider the ease and cost of installing a Level 2 charging station at your home. If it's straightforward and affordable, Level 2 charging becomes a more attractive option.

  • Travel Needs: If you frequently take long road trips, having access to DC Fast Charging stations may be essential to reduce charging downtime during your journeys.

  • Budget: Level 1 charging is the most budget-friendly option, while Level 2 charging offers a balance of speed and affordability for many EV owners.


  • Is Level 2 charging bad for EV?

    Level 2 charging is not bad for your EV. It's a recommended and safe method of charging. EVs are designed to handle Level 2 charging, and it's often more convenient than Level 1 for daily use.

  • Is it cheaper to charge with Level 1 or Level 2 charger?

    Level 1 charging is typically cheaper because it uses standard household outlets. Level 2 charging may involve installation costs, but the exact cost difference depends on electricity rates and installation expenses.

  • Is it better to charge level 1 or level 2?

    The choice between Level 1 and Level 2 charging depends on your needs. Level 2 is faster and more suitable for daily charging, while Level 1 is slower but can be adequate for overnight charging.

  • Is Level 1 charging enough?

    Level 1 charging can be sufficient for many EV drivers, especially if you have a short daily commute and can charge overnight. However, if you need quicker top-ups or have a longer daily driving distance, Level 2 charging may be a better choice.
