Evaluate the charger's power output in kilowatts (kW). Higher kW ratings translate to faster charging times, provided your EV supports it. Below are the typical classifications in wattage:-
Level 1: 1.4 kW (120V) – Suitable for overnight charging.
Level 2: 7.2–22 kW (240V) – Ideal for home charging with significantly reduced times.
DC fast charging: 50–350 kW – Best for rapid charging.
It is essential to ensure your EV charger aligns with your vehicle's charging standards. Compatibility involves matching the charger's connector type, power capabilities, and communication protocols to the requirements of your specific EV. Here's how this applies to both AC & DC charging:-
In North America, most EVs use the Type 1 (SAE J) connector for AC charging.
The Type 2 connector is standard for AC charging in Europe and many other countries due to its three-phase power support.
Ensure the charger you choose provides the connector type that matches your EV.
Confirm that your electric car charger supports the maximum AC charging rate your EV can handle. For example, if your EV supports up to 7.2 kW but the charger is limited to 3.6 kW, the charging speed will be slower.
Before purchasing an EV car charger, evaluate your home’s electrical capacity as,
Level 2 chargers require a 240V outlet, which may involve upgrading your circuit breaker panel or installing a dedicated circuit.
The typical amperage for these electric car chargers for home ranges from 16A to 50A, demanding proper load calculations to prevent overloading.
Engage a licensed electrician to assess compliance with National Electric Code (NEC) standards and local regulations.
Additionally, consider proximity to your parking spot along with proper Garage Light Fixtures for proper lighting. Ensure cost-effective cabling and also weatherproof enclosures for outdoor setups. Some manufacturers offer bundled installation services, reducing logistical challenges. Early planning avoids unforeseen costs and installation delays.
Smart chargers provide advanced functionality like scheduling, remote monitoring, and energy usage tracking via a smartphone app or web interface. These features optimize charging during off-peak hours, reducing electricity costs and supporting grid stability. Some EV home charger models integrate with home energy management systems or solar panels for sustainable energy use. Voice control and Wi-Fi/Bluetooth connectivity add convenience. Consider your tech preferences and need to select an electric car charger with useful, user-friendly smart features.
Safety is paramount when investing in an EV charger. Here are certain things you should keep in mind:
Ensure the product is certified by a recognized testing organization, such as UL, ETL, or TÜV, which verifies compliance with safety standards.
Built-in protections against overcurrent, overvoltage, and short circuits are essential to prevent electrical hazards.
Ground fault circuit interrupters (GFCI) mitigate shock risks, especially in damp conditions.
Temperature sensors and automatic shut-off mechanisms safeguard against overheating.
Chargers with tamper-resistant features add an extra layer of safety for families with young children.
These features are non-negotiable, providing a secure charging experience for both vehicle and home infrastructure.
Portable EV car chargers are increasingly popular for their adaptability. Weighing between 5 to 10 pounds, they are compact and easy to transport. Many come with universal plugs, such as NEMA 14-50 or standard 120V options, offering both Level 1 and Level 2 charging capabilities. Ideal for renters, road trips, or secondary charging locations, they provide a practical solution without requiring permanent installation. However, ensure the electric vehicle charger meets essential safety and durability standards. Features like adjustable amperage settings and included carrying cases enhance usability.
For households with more than one EV or plans to own different EV home charger models in the future, investing in a multi-compatible charger is prudent.
Look for chargers with universal connectors like the SAE J, compatible with most non-Tesla EVs, and adapters for Tesla vehicles.

The answer to this question is based on the following factors:
1) How many miles do you drive every day?
2) Do you have a fully electric car, or is it a plug in hybrid (gas and electric).
For short range driving and plug in hybrid cars: If you only drive less than 40 miles per day, or if you have a plug in hybrid car, you can use a charger that plugs into a standard wall outlet (120 volt). These chargers will provide you with 2-5 miles of driving range for every hour of charging. These chargers are convenient and economical, but are limited in their output and the charging rate is slow. Using industry terms, these are called “Level 1 EV Chargers.”
For longer range driving and for fully electric cars: If you drive more than 40 miles per day, and you have a fully electric car, then you need a 240 volt charger. These chargers are larger and require professional installation, but provide 10-20 miles of charging range per hour of charging. Using industry terms, these are called “Level 2 Chargers".
EV Charger TypeAverage Charging Rate

10 to 20 miles of range (chargers wired to 50A provide even faster charging)Choosing a charger that has earned the ENERGY STAR label means energy savings, safety, convenience, and smart technology. Find ENERGY STAR certified Electric Vehicle Chargers (AC-Output) and Electric Vehicle Chargers (DC-Output).
Energy Savings: EV chargers are typically in standby mode (i.e., not actively charging a vehicle) for about 85% of the time. ENERGY STAR certified EV chargers provide the same functionality as non-certified products but use 40% less energy in standby mode, reducing their impact on the environment. If you have the option, charging your EV with green power (PDF, 172 KB) , sourced from emissions-free electricity sources, offers additional environmental benefits.
Greater efficiency = more savings! When choosing an EV charger, it is helpful to note that Level 2 chargers provide higher charging efficiency and faster charging times when compared with Level 1 chargers. As shown in the table above, Level 2 charging is on average 10% more efficient than Level 1, while adding approximately four times more miles per hour of charging.
Safety: Not all EV chargers that are for sale are safety certified, including some from large online and storefront retailers. To ensure your charger meets safety standards, choose one that has earned the ENERGY STAR label. All ENERGY STAR certified chargers are tested for safety by a nationally recognized testing laboratory.
Smart Technology: Some ENERGY STAR certified EV charger models are connected, also referred to as networked, allowing for remote power monitoring and control of the charging state of the connected vehicle. These smart grid ready products may qualify households and property managers to participate in special energy bill savings programs that may be offered by some local electric utilities.
EV owners ideally have access to overnight charging, in their driveway/garage or wherever they park their car. Without overnight charging, EV owners can charge at some workplaces, or use public charging.
Ask the dealer. Homeowners who are purchasing a new EV are typically offered a 120V charger (also called a cord set) as part of their vehicle purchase or lease, rather than having to purchase it independently. However, there are advantages to upgrading to a 240V charger, including faster charging times, which may be necessary to charge longer-range EVs overnight. When shopping for an electric vehicle, ask the dealer if they sell or work with electrical contractors that have ENERGY STAR certified EV chargers.
Ask the retailer. 120V and 240V EV chargers are sold by big-box and independent retailers, mainly online. Purchase an ENERGY STAR certified EV charger to ensure it meets key industry safety standards. Non-ENERGY STAR certified chargers may not be safety certified. In fact, many products sold by some major retailers may have false safety certifications displayed.
Hire a contractor. Contact a licensed electrician to evaluate whether your home’s wiring, electrical outlets, and other hardware can support the charging requirements of your EV. Your car dealer or the EV manufacturer may also recommend a third-party or contractor network that may be able to conduct a home assessment.
Use green power to charge your car. Using “green power” from your electricity supplier will provide a maximum environmental benefit. Not only will you be eliminating carbon emissions from your tailpipe and electricity generation, you will also be supporting green power suppliers. For more information on how to do this, see EPA’s Guide to Charging EVs with Green Power (PDF, 172 KB) .

Seek the guidance of a local contractor. Installation varies from simple to complex. For some customers, it may be simple to install a new two-pole circuit breaker, wiring, and the EV charger. For other customers, installation can get more complex; these customers may need to upgrade service, install a new load center and conduit through walls, comply with codes, factor in long wiring distances, and perform transformer upgrades. In some cases, it might be best to add new EV charging capacity directly from the transformer on the perimeter of the parking lot, rather than from the building out to the parking lot since this approach can avoid expensive trenching. Qualified electrical contractors will assess the site and provide recommendations.
Recoup installation costs. There are various incentives at the local, state, and federal level for EV charging equipment and installation, including those offered by utilities. Your local electric utility may also have a Demand Response (DR) program or time-of-use electricity rates that will allow EV charging station hosts to take advantage of lower pricing during off-peak hours.
Maintain equipment. EV chargers may require periodic inspection, testing, and preventive maintenance typically performed by a qualified electrical contractor. Annual maintenance costs can vary but are generally low. Many EV charging service providers offer optional maintenance plans.
