What a public EV charger is and where to find one

A public EV charger is a plug-in station that charges electric vehicles and is open to the general public, usually for a fee. Unlike a charger at your home or workplace, you can use it without owning the equipment. Public chargers sit in parking lots, along highways, at shopping centers, apartment buildings, and municipal parking garages.

The easiest way to find one near you is to use a mapping app built for this purpose. PlugShare, ChargePoint, and EVgo all show real-time availability, pricing, and connector types in your area. Google Maps also displays EV charging stations and some availability information. Type your location or search along a planned route, and the app will show you which chargers are working, how many open spots exist, and what you'll pay.

Public chargers are run by different companies and municipalities. ChargePoint operates thousands of Level 2 chargers (slower, cheaper charging). Tesla Superchargers are fast chargers on highways, though Tesla has begun opening them to other brands. Electrify America, EVgo, and Volta operate networks across the country. Your city or county may also run chargers in public parking areas.

Key Takeaways

  • Public EV chargers are located in parking lots, shopping centers, highways, and municipal garages, and you can find them using PlugShare, ChargePoint, or Google Maps.
  • Level 2 chargers take 4 to 10 hours to fully charge a vehicle and cost $1 to $3 per hour, while DC fast chargers take 20 to 45 minutes and cost $10 to $30 per session.
  • You need a compatible connector for your vehicle — most newer EVs use the NACS connector, but older models may need an adapter or a different charger type.
  • Most networks require you to create an account and link a payment method before you can start charging.

The two main types of public chargers and how long they take

Level 2 chargers are the most common public option. They plug into a standard 240-volt outlet (the same type used for electric dryers) and charge slowly but steadily. A full charge typically takes 4 to 10 hours depending on your vehicle's battery size. Level 2 chargers cost between $1 and $3 per hour of charging, or sometimes a flat fee of $2 to $5 per session. You'll find them in parking lots, shopping centers, and apartment buildings where people park for hours.

DC fast chargers use direct current to charge much faster — usually 20 to 45 minutes for 80 percent of a full charge. They cost more, typically $10 to $30 per charging session, and are located along highways and in urban areas where drivers need to charge quickly. DC fast chargers are what you'd use on a road trip; Level 2 chargers are what you'd use while shopping or working.

The speed and cost difference matters for your budget and your routine. If you charge at work or while running errands, Level 2 is usually cheaper and fine for your needs. If you're driving long distances or need a quick top-up, DC fast charging is worth the extra cost.

Connector types and whether your vehicle will fit

Not all chargers work with all vehicles because of different connector types. The NACS connector (North American Charging Standard) is now the standard for new electric vehicles sold in the U.S., including Tesla, Ford, General Motors, and others. Most new public chargers are being installed with NACS connectors.

Older electric vehicles may have a CCS connector (Combined Charging System) or a Tesla connector. If your vehicle doesn't match the charger, you have two options: use an adapter (if your vehicle supports one) or find a different charger. The mapping apps show which connector types each station has, so you can filter for ones that work with your vehicle before you drive there.

Before you visit a new charger for the first time, check the app to confirm the connector type matches your vehicle. This prevents a wasted trip.

How to start charging at a public station

Most networks require you to set up an account before you can charge. read the network's app (ChargePoint, EVgo, Electrify America, or whichever operates the charger you want to use), create an account with your email and payment method, and add your vehicle information. Some networks let you pay with a credit card at the charger itself, but having an account is faster and more reliable.

When you arrive at the charger, open the app and select the specific charger location. The app will unlock the charger, and you'll plug your vehicle in. The charging begins automatically, and the app shows you real-time progress. You'll receive a notification when charging is complete or if there's a problem.

Pricing is usually per hour (Level 2) or per session (DC fast), though some networks charge by kilowatt-hour (the actual amount of electricity used). Check the app before you start so you know what you'll pay. Many networks offer monthly subscriptions that lower the per-use cost if you charge frequently.

What to do if a charger is broken or occupied

Chargers break down, and popular stations fill up. The mapping apps show real-time status — green means available, red means in use, and gray means out of service. If your chosen charger is broken or full, the app will show you the next nearest option and how far away it is.

If you arrive at a charger and find it's not working, report it through the app. Most networks have a "report a problem" button that alerts maintenance. You won't be charged if the charger malfunctions before you finish.

During peak times (lunch hours, evenings), popular chargers may have a wait. Plan ahead by checking availability before you leave home, or choose a less busy location if you have time.

Pricing differences between networks and how to save money

Charger networks set their own prices, so costs vary by location and operator. A Level 2 charger at a ChargePoint station might cost $2 per hour, while an Electrify America charger nearby costs $2.50. DC fast chargers vary more widely — some charge $0.35 per kilowatt-hour, others charge a flat $15 per session. The mapping apps show the price at each station before you commit.

If you charge regularly, monthly subscriptions often save money. ChargePoint Plus costs about $10 per month and reduces per-use fees. Electrify America's membership is around $4 per month and gives you discounts on DC fast charging. Calculate whether a subscription pays for itself based on how often you charge.

Workplace and apartment chargers are sometimes free or subsidized by your employer or landlord, so check what's available to you before paying for public charging. Many employers offer free Level 2 charging as an employee benefit.

Public charging on road trips and long drives

For road trips, plan your route using the mapping app before you leave. Most apps let you enter your destination and show you chargers along the way, with estimated charging time at each stop. DC fast chargers are your friend on highways — they're designed for drivers who need to charge quickly and keep moving.

A typical highway charging stop takes 30 to 45 minutes. You'll drive to the charger, plug in, grab food or use the restroom, and leave. Many DC fast chargers are located at rest stops or near restaurants, so you can charge while you eat.

read the apps for the major networks (EVgo, Electrify America, ChargePoint) before your trip so you have them available offline. Some areas have spotty cell service, and having the app already installed ensures you can find chargers even if your connection is slow.

Frequently Asked Questions

Do I have to pay every time I charge at a public charger?

Most public chargers charge a fee, but some are free. Free chargers are usually at workplaces, apartment buildings, or municipal parking areas as a community benefit. The mapping apps show which chargers are free and which charge a fee. Paid chargers typically cost $1 to $3 per hour for Level 2 or $10 to $30 per session for DC fast charging.

Can I charge my non-Tesla EV at a Tesla Supercharger?

Tesla has opened some Superchargers to other brands, but not all. You'll need an adapter or a compatible connector. Check the Tesla app or the mapping app to see which Superchargers near you accept non-Tesla vehicles. Availability varies by location and changes over time.

What happens if I leave my car plugged in after charging is done?

Most networks charge an idle fee if you leave your vehicle plugged in after charging completes. The fee is usually $0.50 to $1 per minute and is meant to encourage drivers to unplug and free up the charger for others. The app will notify you when charging is complete so you can unplug promptly.

Can I charge at a public charger if I live in an apartment?

Yes. Public chargers are designed for anyone with an EV, regardless of where you live. If your apartment building doesn't have chargers, you can use public Level 2 chargers in parking lots or municipal garages. Many apartment dwellers charge while at work or shopping to avoid paying for public charging.

Do I need a special credit card or membership to start?

No. You can create an account with any credit card and start charging when ready. Some networks offer memberships that reduce per-use costs, but they're optional. You can also pay at some chargers with a credit card without creating an account, though an account is usually faster and more reliable.
