The Difference Between Level 1 & Level 2 EV Chargers
On this page
As electric vehicles (EVs) gain traction in the global automotive market, understanding the charging options available is crucial for owners looking to make the most of their EV experience. Most EVs come with a Level 1 charger included by the manufacturer, designed to plug into a standard 120-volt (120V) outlet at home. While this charger can get the job done, upgrading to a Level 2 EV charger offers significant advantages in speed, convenience, and efficiency, making it a worthwhile investment for many EV owners.
In essence, a Level 2 EV charger transforms your garage into your personal fueling station, capable of recharging your vehicle quickly and reliably. Furthermore, Level 2 chargers often come with smart features, allowing you to schedule charging during off-peak hours, saving on electricity costs. Let’s break down the key differences between Level 1 and Level 2 EV chargers to help you decide which option best suits your needs.
On average, a Level 1 charger adds 3 to 5 miles of driving range per hour of charge. This means that fully recharging an all-electric EV from empty to full could take anywhere from 40 to 60 hours. For plug-in hybrid electric vehicles (PHEVs), which have smaller batteries, the charging time is significantly shorter, ranging from 5 to 6 hours for a full charge.
While the extended charging time of Level 1 equipment may seem like a drawback, these chargers are safe and reliable. The 120V power supplied by Level 1 chargers poses no additional safety risks, making them a practical solution for EV owners who drive short distances or have the flexibility to charge overnight over several days.
With a Level 2 charging station, the typical charging time from empty to full ranges between 4 to 8 hours, depending on the vehicle’s battery capacity. This means that you can fully recharge your EV overnight or even during a workday, ensuring that your vehicle is ready to go whenever you need it.
Level 2 chargers require a 240-volt (240V) outlet, similar to what is used for larger household appliances like dryers or ovens. While this means that professional installation may be necessary, the time saved and increased charging efficiency make the investment worthwhile for many EV owners.

How Fast is a Level 1 EV Charger?
Level 1 EV chargers, commonly included with the purchase of an EV, operate at a power range of 2 to 5 kilowatts (kW). These chargers utilize a standard 120V alternating current (AC) outlet, similar to what you use for household appliances. While convenient and easy to use, Level 1 chargers are relatively slow in terms of charging speed.On average, a Level 1 charger adds 3 to 5 miles of driving range per hour of charge.

How Fast is a Level 2 EV Charger?
A Level 2 EV charger offers a substantial upgrade in terms of charging speed and convenience. Operating at a power range of 6 to 19 kilowatts (kW), Level 2 chargers are capable of adding 25 to 32 miles of driving range per hour of charge. This translates to a charging speed that is up to 8 times faster than a Level 1 charger.With a Level 2 charging station, the typical charging time from empty to full ranges between 4 to 8 hours, depending on the vehicle’s battery capacity.

Why Upgrade to a Level 2 Charger?
For many EV owners, the decision to upgrade to a Level 2 charger comes down to convenience and practicality. Here are a few reasons why a Level 2 charger might be the right choice for you:1. Significantly Faster Charging
If you drive your EV daily or cover long distances regularly, a Level 2 charger can dramatically reduce your downtime. The ability to fully recharge in just a few hours ensures that your vehicle is always ready for the road.2. Future-Proofing
As EV technology advances, battery capacities are expected to increase, which means longer charging times for Level 1 chargers. A Level 2 charger can handle higher power levels, making it a better long-term solution.3. Energy Cost Savings
Many Level 2 chargers come with smart features that allow you to schedule charging during off-peak hours, when electricity rates are lower. This can lead to significant savings on your energy bills over time.4. Convenience at Home
Having a Level 2 charger installed at home eliminates the need to rely on public charging stations, saving you time and money. It’s like having a gas station in your garage, but much cleaner and quieter.Considerations for Installation
Upgrading to a Level 2 charger requires some upfront planning and investment. Here are a few factors to keep in mind:Electrical Panel Capacity
Ensure that your home’s electrical panel can support the additional load of a 240V charger.
Installation Costs
Professional installation may cost between $300 and $1,500, depending on the complexity of the setup.
Charger Features
Look for features like Wi-Fi connectivity, adjustable power settings, and compatibility with your EV model.
