If you seek the answer to the question: Can I use any charger to plug in my electric vehicle? Read on, and your learning curve will soon get straightened out.

There is both a simple answer to this question and a more complex one. The most straightforward answer is yes. The EV manufacturer provides you with a mobile charging cord that can plug into a regular household outlet or a more powerful 240-volt outlet (shown above) that you would use to power an electric clothes dryer.

Where it gets more complex is your vehicle’s compatibility with public charging stations and what charging choices you will have at home. Mass-market electric vehicle (EVs) and plug-in hybrid vehicles (PHEVs) offer a decade-long charging history and the systems continue to evolve.

This article will explain what chargers you can use, the exceptions, a description of the three levels of charging speeds, and details to help you identify the four connector types. We will also recommend strategies for charging your EV or PHEV at home.

Charging Speeds Explained

Let’s start by unraveling the complexities and a short explanation of your charging choices. Remember, each EV and PHEV is different.

The two most significant inconsistencies with charging systems are:

  1. Tesla’s connector is unique compared to others (thank you, Elon Musk).
  2. The Nissan Leaf, Mitsubishi Outlander PHEV, and Kia Soul EV models do not use the current United States standard connector.

Besides the exceptions, all EV and PHEV vehicles in the U.S. use a standardized connector called the CCS1. More on that below.

Your car’s user manual will tell you if your vehicle has any limitations on the safest and most economical type of charging for your model. But for now, this is the basic layout of charging types:

Level 1: Trickle Charge

The lowest charging rate is to plug into an average 120-volt wall plug. This charge rate could take up to 30 hours to fully charge an EV and 10 hours to charge a PHEV.

Level 2: Fast Charge

The faster way to charge is with a 240-volt plug like the type that would power an electric clothing dryer. A public charging station supplies this charging level, as does a wall unit or 240-volt outlet at home. With it, a Level 2 charge can take between 4 to 7 hours.

NOTE: You should consult your electrician before charging your EV or PHEV with a 240-volt outlet at home.

Level 3: Rapid Charge

A fast or rapid charge is also known as a direct current or DC fast charger. This is the fastest you can charge an EV and it’s only available at public charging stations, including Tesla Supercharger stations. This 400- to 600-volt charge provides direct power to the battery and can reach an 80% charge in less than a half-hour. These types of chargers are only available for EVs, not PHEVs. Some EV batteries cannot handle charges at such high wattage. For instance, some can accept 350 kW while some only can accept 50 kW.

Sadly, a dirty little secret about Level 3 charging is that the highest speed is the toughest on your battery. Many automakers even added a warning inside their car manuals. For instance, some EV models may note that frequent use of DC fast charging can negatively impact battery performance and durability, and recommend minimizing its usage.

Please read your manual to review the limitations of your EV when it comes to rapid charging.

Connector Types: What You Need to Know

The main two plugs covering 96% of cars in the U.S. market are the Combined Charging System Type 1, or CCS1, and the Tesla connector, exclusively for use with Tesla models. You need only one plug to charge your vehicle at all levels for cars equipped with these two plug types.

CCS Type 1 Connector 

A standard plug type was developed and endorsed by the Society of Automotive Engineers (SAE). CCS1 “combines” the standard J1772 connector with two high-speed charging pins. About 80% of EVs and 85% of PHEVs carry this plug connector. Like Tesla, this single plug can be used for Level 1, Level 2, or Level 3 (DC fast charging).

Tesla Connector

First, embrace that, much like Elon Musk himself, Tesla chargers are unique. Most of Tesla’s public charging stations provide Level 3 Tesla Superchargers, giving an 80% charge in only 20 minutes. Tesla is busy building its proprietary Supercharger stations across the country. Still, at this point, there are only around 6,000 Tesla charging posts compared with the more than 47,000 regular public charging stations.

Instead, drivers of other EVs can take advantage of Tesla Destination Chargers, which are Level 2. An electric vehicle owner can buy a Tesla-to-J1772 adapter and connect a Destination Charger to their car’s charging port.

While a third-party adapter works for the Level 2 Tesla Destination Chargers, non-Tesla EVs cannot use Tesla’s fast chargers yet. Only Tesla models can use Superchargers. Tesla plans to open its Supercharger network to other EVs, but as of this writing, it’s not yet available.

The Outliers: Leaf, Outlander, and Kia Soul EVNissan Leaf charging sockets

What differentiates these three vehicles is that they have two (not a single) connector slots. One is for Level 1 and Level 2 charging, and the other is for Level 3 DC fast charging. The good news is that the J1772 connector for Levels 1 and 2 works at regular (non-Tesla) charging stations. The other connector is a CHAdeMO and is a standard Level 3 (DC fast charging). However, this technology is being phased out at public charging stations. In the past decade, the CHAdeMO, lost the battle for standardization in the U.S. market.

2011-2022 Nissan Leaf and 2022 Mitsubishi Outlander PHEV – J1772 and CHAdeMO connectors

It would be nice if that was the entire story, but here in 2022, we are still in a transition. Two current models carry two outlets for charging — the Nissan Leaf and Mitsubishi Outlander PHEV — but only with regard to their DC fast charging. These two 2022 models have not yet phased out of the CHAdeMO Japanese standard plug. In these vehicles, there are two separate plugs — a J1772 connector for Level 1 and Level 2 charges, and the CHAdeMO plug. There are nearly a million Leaf models worldwide that share this non-standard plug structure.

2015-2019 Kia Soul EV J1772 and CHAdeMO Connectors

Since you can still find used 2015-2019 Kia Soul EVs in the market, it’s worth mentioning how these plugs differ from other Kia EVs. During those model years, the Kia Soul EV still used the two-plug combo of J1772 and CHAdeMO. However, the manufacturer began using the CCS1 single plug on its current electrified models, including the Niro EV and the EV6.

Your EV Charging Choices at Home

When an EV or PHEV enters your lifestyle, charging your vehicle at home while you sleep is optimal. Many EV owners prefer overnight charging due to the safety, convenience, and lower electricity cost. But not everyone’s situation works the same. Here are the three situations that EV and PHEV drivers choose based on their at-home charging needs.

At-Home Wall Unit 

A popular EV lifestyle strategy is to install a more powerful 240-volt wall unit at home for convenient Level 2 fast charging. In most cases, EV owners purchase an in-home charging “smart” wall unit. These units can send notifications and schedule charging when it suits your schedule. The units cost between $400 to $700, depending on the brand. Many EV owners prefer this type of charger.

Note: You should consult an electrician before installing the wall unit because the units differ when installed outside versus inside a garage. Also, electric power availability varies in each home.

At-Home 240-Volt Plug with Mobile Connector 

An upgraded 240-volt outlet will give you the same Level 2 charge that a wall unit would provide but without the connectivity. Most mobile charging cords include a 240-volt connector or adapter. Many PHEV owners choose this charging solution because they only need to charge for a short period.

At-Home 120-Volt 3-Pronged Electrical Plug

The 120-volt outlet is the standard in homes since the 1950s. It provides a Level 1 “trickle charge” that can always do in a pinch. Older home electrical challenges and detached garages can make it impossible or too expensive to charge in some living situations. This style of charging happens more commonly than you might think. Some vehicles, such as the Nissan Leaf, can take up to 30 hours or more to fully charge using this Level 1 charging option.

Note: Most manufacturers advise not using an extension cord with a charging cord for your vehicle.

Public Charging Stations: Growing Every Day

As you can guess, there are many more public charging stations for electric vehicles with CCS1 connectors than Tesla stations. And further, there are far fewer stations that provide CHAdeMO-connected DC fast charging since that technology is limited.

Level 3 is Gaining in Numbers

It’s no surprise that there’s higher consumer demand for electric charging, especially in Level 3 fast charging. As a result, Tesla plans to install up to 31% more of its Superchargers globally by the end of 2022. As for other public charging stations, companies added more than 4,000 Level 3 chargers to existing U.S. public stations in 2021.

How Many U.S. Charging Stations are There?

As of this writing, the U.S. Department of Energy’s Alternative Fuels Data Center reports the following:

All U.S. Charging Stations:

  • Number of Stations: More than 48,000
  • Number of Chargers: More than 119,200

CHAdeMO Charging Stations:

  • Number of CHAdeMO DC Fast Charging Stations: 4,343
  • Number of CHAdeMO Fast Charging Units: 6,094

CCS1 Charging Stations:

  • Number of CCS1 Charging Stations: 44,132
  • Number of CCS1 Charging Units: 91,608

Tesla Charging Stations:

  • Number of U.S. Tesla Stations: 5,980
  • Number of U.S. Tesla Charging Units: 25,320

There’s an App for That 

Do your research and study a map of which charging stations along your route take your car’s particular charging outlet. A handy one is called the PlugShare app, which shows the charging plugs that each station supports.
