As electric vehicles (EVs) continue to grow in popularity, one of the key considerations for EV owners is how to charge their vehicles efficiently. While public charging stations are available, many EV owners prefer to charge their cars at home for convenience and cost savings. However, choosing the right home charging solution can be a bit overwhelming, especially when deciding between the two most common types of chargers: Level 1 and Level 2.

In this guide, we will explore the differences between Level 1 and Level 2 EV chargers to help you make an informed decision about which option best suits your needs. Whether you’re new to electric vehicles or considering upgrading your home charging setup, understanding the benefits, drawbacks, and suitability of each charger type is crucial.

What is a Level 1 EV Charger?

A Level 1 EV charger is the most basic and widely accessible charging option for electric vehicles (EVs). It uses a standard 120-volt household outlet to provide power to the vehicle’s battery. This makes it a convenient and inexpensive option for EV owners, but it also comes with certain limitations in terms of charging speed and practicality for long-distance driving.

Basic Functionality and Charging Speed

Level 1 chargers are often the first point of entry for new EV owners because they don’t require any specialized equipment or installation. All you need is the standard electrical outlet available in most homes. A typical Level 1 charger uses a 120-volt AC power source to charge the EV.

In terms of charging speed, Level 1 is relatively slow compared to other charging options. On average, a Level 1 charger adds about 3 to 5 miles of range per hour of charging. This means that charging an EV from empty to full could take upwards of 24 hours or more, depending on the vehicle’s battery capacity. However, this slow speed is usually sufficient for drivers who don’t need to charge their vehicle frequently or for those who don’t drive long distances each day.
