Introduction to EV Chargers

Electric vehicles (EVs) are gaining rapid popularity as a sustainable alternative to gasoline cars. One of the essential aspects of owning an EV is understanding the different types of chargers available to keep your vehicle running. In this blog post, we at Stan's Heating, Air, Plumbing & Electrical aim to explore the various types of EV chargers that we offer, explain their pros and cons, and help you make an informed choice.

Level 1 Chargers

Description and Functionality

Level 1 chargers utilize the simplest form of EV charging technology. They operate at a 120V alternating current (AC), which is the standard voltage for household electrical outlets in the United States. This charger uses a three-pronged connector that fits into a standard wall outlet and a connector that plugs into your vehicle. Typically, the charger contains a simple box on the cable that converts household AC electricity into direct current (DC) that can be fed into your car's battery.

Pros and Cons


  • No Extra Installation: One of the major advantages of Level 1 chargers is that they require no special installation. You can simply plug them into a standard household electrical outlet.
  • Portability: These chargers are highly portable and can be easily taken with you if you move homes or even if you just need to charge while visiting friends or family.
  • Low Upfront Cost: Typically, Level 1 chargers come with the vehicle, making them an economical choice for those who are budget-conscious.


  • Slow Charging: One of the downsides of Level 1 chargers is their slow charging speed. You'll gain only around 3-5 miles of range per hour of charging, making it impractical for quick top-ups.
  • Limited Usefulness for Long Journeys: Due to their slow charging rate, these chargers are not ideal for long road trips where you need to recharge quickly.

Ideal Use Cases

Level 1 chargers are perfect for people who drive limited distances and can afford to charge overnight.

Level 2 Chargers

Description and Functionality

Level 2 chargers operate at 240V AC, which is the same electrical voltage often used for household appliances like ovens and dryers. Unlike Level 1 chargers, Level 2 units typically need a dedicated circuit and are hardwired to the electrical grid. They often include smart technology, enabling you to control the charger via a mobile app. The charger's internal box converts the AC electricity from the grid into DC form that your EV’s battery can store.

Pros and Cons


  • Faster Charging: Level 2 chargers offer substantially faster charging speeds compared to Level 1, allowing for 10-60 miles of range per hour.
  • Programmable Charging: Many Level 2 systems offer smart features, including the ability to program charging times to take advantage of off-peak electricity rates.
  • Increased Home Value: Having a Level 2 charger installed can also increase the resale value of your home, making it an investment for the future.


  • Installation Required: Unlike Level 1 chargers, Level 2 units need professional installation, which can sometimes be costly.
  • Permitting and Code Compliance: Installation often requires adherence to local building codes and electrical standards, which may necessitate permits and inspections.

Installation Requirements

A 240V circuit is essential, and installation should be carried out by certified electricians like the ones at Stan's Heating, Plumbing & Electrical.
