What public charging points are and where to find them

Public charging points are stations where you can charge an electric vehicle outside your home or workplace. They are installed in parking lots, on street corners, at shopping centers, and along highways. Unlike a home charger that you own, public chargers belong to cities, utilities, private companies, or networks that operate them for general use.

Finding a public charger near you starts with a smartphone app or website. The most widely used apps are PlugShare, ChargePoint, EVgo, Electrify America, and Tesla Supercharger (for Tesla owners). Each app shows you the charger's location, whether it is available right now, what type of connector it uses, and what it costs. Some chargers are free; others charge by the hour, by the kilowatt-hour, or by subscription.

Your city or regional transit authority may also list public chargers on their website. Many utilities publish maps of chargers in their service area. If you are unsure which app covers your region, search "[your city] EV charging" to find the local network.

Key Takeaways

  • Public charging points are owned and operated by cities, utilities, or private networks, and you find them using apps like PlugShare, ChargePoint, or EVgo.
  • Chargers come in three speeds — Level 1 (slowest, rarely public), Level 2 (common in parking lots, takes 4 to 10 hours), and DC fast chargers (highway stops, 20 to 45 minutes).
  • Most public chargers require you to create an account and link a payment method before you can use them, even if the charging itself is free.
  • Availability changes throughout the day, so checking the app before you leave home tells you whether a charger is working and whether a spot is open.

The three types of public chargers and how long they take

Level 2 chargers are the most common public option. They deliver power slowly and typically add 25 to 30 miles of range per hour. A full charge from empty takes 4 to 10 hours depending on your vehicle's battery size. You will find Level 2 chargers in parking lots at grocery stores, shopping centers, workplaces, and apartment buildings. Many are free or cost $1 to $3 per hour.

DC fast chargers are much quicker and are installed mainly along highways and in city centers. They add 100 to 200 miles of range in 20 to 45 minutes. DC fast chargers cost more — typically $10 to $30 per session or $0.25 to $0.50 per kilowatt-hour — because they deliver power at high speed and wear out faster. They are designed for road trips and urgent top-ups, not daily charging.

Level 1 chargers use a standard household outlet and are rarely installed as public chargers because they are too slow (adding only 2 to 5 miles per hour). You may encounter them at some workplaces or older installations, but they are not practical for public use.

Before you visit a charger, check the app to confirm it has the right connector type for your vehicle. The most common types are Tesla (proprietary to Tesla vehicles), CCS (used by most other brands in North America), and CHAdeMO (older standard, less common now).

How to set up an account and pay for charging

Most public charging networks require you to create an account before your first use. read the app or visit the network's website, enter your email address, create a password, and link a payment method (credit card or debit card). Some networks let you pay per session; others offer monthly or annual memberships that reduce the per-use cost.

A few chargers are truly free and do not require an account — usually those installed by cities or nonprofits. Check the app or call ahead to confirm. Even free chargers sometimes ask you to register so they can track usage.

When you arrive at a charger, open the app, find the specific charger number or location, and select "Start Charging." The charger will unlock and you can plug in. The app will show you how much charge you have added and how much you are being charged in real time. When you are done, unplug and the app will show your final bill.

What to do if a charger is broken or occupied

Chargers break down, and parking spots fill up. The app will show you whether a charger is "available," "in use," or "offline." If a charger is offline, the app usually lets you report the problem or see when it was last serviced. Do not assume it will be fixed soon — some chargers stay broken for weeks.

If all nearby chargers are in use, the app will show you how long the current user has been charging and how many people are waiting. You can add yourself to the queue and the app will notify you when a spot opens. Alternatively, expand your search radius in the app to find chargers a few miles away.

If you arrive at a charger and find it physically blocked by another car or debris, take a photo and report it through the app. The network operator will investigate and may contact the person blocking the charger.

Charging on a road trip versus daily charging

Road trips and daily charging use different chargers. For a road trip, plan your route using the app and locate DC fast chargers along highways. These stops typically take 30 to 45 minutes, which is long enough to grab food or use a restroom. Apps like PlugShare and A Better Route Planner let you input your destination and show you which chargers are on the way.

For daily charging — if you do not have a home charger — use Level 2 chargers at your workplace, a nearby parking lot, or a shopping center where you spend time anyway. Charge while you shop or work so the time does not feel wasted. Many employers and retailers offer free Level 2 charging to customers and employees.

If you rely entirely on public charging and have no home charger, plan to charge more often and for longer. A Level 2 charger adds only 25 to 30 miles per hour, so you cannot top up quickly between errands the way you would at a gas station.

Membership plans and subscription options

Most large charging networks offer monthly or annual memberships that lower the per-use cost. ChargePoint, EVgo, and Electrify America each have different pricing tiers. A typical membership costs $10 to $20 per month and might reduce your per-kilowatt-hour rate from $0.30 to $0.20, or waive session fees.

Some networks offer pay-as-you-go pricing with no membership required. Others bundle charging into a subscription that includes roadside information or other perks. Compare the networks in your area to see which pricing model fits your driving habits.

If you charge at the same location regularly (your workplace, for example), ask whether that location offers a direct membership or discount. Many employers and apartment buildings negotiate group rates with charger operators.

Etiquette and common courtesy at public chargers

When your vehicle is fully charged, unplug it and move it so the next person can use the spot. Leaving a fully charged car at a charger ties up the spot and frustrates other drivers. Some networks charge an "idle fee" ($0.50 to $1.00 per minute) if you do not move your car within 5 to 10 minutes of finishing.

Do not unplug someone else's vehicle. If a charger is occupied and you need it, wait in the queue or find another charger. If a car has been parked there for hours and the app shows it finished charging long ago, report it through the app so the network can contact the owner.

Keep the charger and parking area clean. Do not leave trash, and do not block the charger with cones or signs to "reserve" it. Chargers are first-come, first-served unless the network has a reservation system.

Frequently Asked Questions

Do I need to own an electric vehicle to use a public charger?

Yes, you need an electric or plug-in hybrid vehicle with a charging port. Public chargers are designed only for vehicles that can accept that type of power. If you are considering buying an electric vehicle, visiting a public charger beforehand can help you understand how charging works in your area.

What happens if I run out of battery before I reach a charger?

Most electric vehicles will warn you when the battery is low and show you the nearest chargers on the vehicle's navigation screen. Plan your route using a charging app before you leave so you know where chargers are. If you do run out of power, roadside information can tow you to a charger, though this is expensive and time-consuming.

Can I charge my vehicle overnight at a public charger?

Some Level 2 chargers in parking lots allow overnight charging, but many do not. Check the charger's rules in the app or call the location. Overnight charging at a DC fast charger is not practical because you would be charged idle fees once your vehicle is fully charged. For overnight charging, a home charger or workplace charger is more reliable.

Are public chargers safe to use at night?

Most public chargers are in well-lit, populated areas like parking lots and shopping centers. Chargers in isolated locations or late at night carry the same safety considerations as any public space. Trust your instincts, stay near your vehicle, and use chargers in busy areas when possible.

What if the charger does not work when I plug in?

The app will usually show an error message or the charger will display a code on its screen. Take a photo of the error, note the charger's location number, and report it through the app. The network operator will investigate. In the meantime, find another charger using the app.
