Every charging port is busy: what to do first
Start with the site's signs, station screen and any official queue. If there is no stated system, ask the waiting drivers who arrived before you and which connections they can use. Our courtesy recommendation is to agree on the order before a space opens, rather than race for it.
| What you see | What to do |
|---|---|
| Cars charging; other drivers waiting | Use the official queue if offered. Otherwise ask who is waiting and agree on the next usable space. |
| An empty bay beside a charger in use | Check the screen and operator app before pulling in. An unused cable may share a unit that cannot serve another car at the same time. |
| An availability notification | Check whether it is an alert or an accepted reservation. Do not assume the space is being held. |
| A car still plugged in after its session | Ask the driver to move if they are present. Otherwise contact the site host or operator and look for an alternative. |
| A bay blocked by a parked vehicle | Ask the host or parking staff for help. Keep the driving aisle clear while you decide whether to wait or leave. |
EVgo explains that a seemingly empty charger can be unavailable because of maintenance, a reservation or another vehicle using the unit. For that last case, check the simultaneous-charging signage; two cables alone do not establish two usable ports. EVgo: a charger looks available but cannot start.
A useful opening question: “Are you waiting to charge, and which connector are you waiting for? I'm trying to work out who's next.” Treat an earlier driver's inability to use a particular connection as something to clarify, not an excuse to skip them.
An alert is not always a place in line
ChargePoint's Notify Me alerts you when a selected charging spot becomes available, but does not reserve it. Its separate Waitlist feature provides a virtual queue at stations where the host has enabled it. These features do not extend to a different network just because you pay through your ChargePoint account. ChargePoint: what to do when all charging spots are busy.
With Waitlist, accept an offered spot only when you are ready to move; acceptance holds it briefly. Snooze if you cannot go yet, or leave the queue if you no longer need a charge. Follow the timing shown for that station instead of assuming every site uses the same window. ChargePoint: what to do when all charging spots are busy.
Where there is no official queue, our recommendation is to stay nearby, leave room for cars to exit and tell the next driver if you decide to leave. A lower battery percentage is a reason to ask for help, not permission to take another person's turn.
Can you unplug someone else's electric car?
Our default advice is no: ask the driver to finish and disconnect their own session. A full-battery display, a slow charge or an open charge-port door is not permission. EVgo generally recommends leaving another vehicle connected even after its session finishes, and using another charger or waiting for the driver. EVgo: unattended vehicles at a charger.
An explicit note from the owner or a managed sharing arrangement can change the conversation, but do not guess what it authorizes. If the instructions are unclear, ask the owner or site staff. Do not force a connector, try to defeat a lock or use charger controls to end someone else's session so you can take over.
Try: “Are you finished charging? I'm waiting for this connection. Would you be able to move when you're ready?” If the driver still needs to charge, ask about their expected departure or choose another stop. Avoid judging their need by the car's badge, battery percentage or charging speed.
This is courtesy guidance, not a nationwide legal ruling about unplugging or towing. For a dispute, use the operator or property manager's process; this guide does not authorize touching another person's vehicle.
When should you move—and is 80% a rule?
Plan to move when you have the charge needed for your next leg, or when the site's session limit requires it. EVgo's courtesy guidance recommends switching to Level 2 at 80%. Treat that as the operator's advice for considerate fast charging, not a rule that every driver at every charger must leave at the same percentage. EVgo: charging etiquette.
A posted limit is different. At selected Electrify America locations marked with an 85% limit, the session ends automatically at that level; the operator says drivers then have ten minutes to move before idle fees. Check the specific station's listing for the limit. Electrify America: congestion reduction effort.
If your next leg needs more energy than a site's limit allows, choose a suitable charging plan before relying on that stop. For why a headline kW rating does not tell you how long the last part of a session will take, see how charging time varies.
Our recommendation when others are waiting: avoid an unnecessary top-up, but do not abandon the energy you need because a stranger says your car should be done. Follow the site's actual limits and use your vehicle's trip guidance; this courtesy checklist is not a range guarantee.
Read the fee trigger, not just the word “idle”
Tesla's current Supercharger policy illustrates the difference: at a busy site, a congestion fee can apply when the battery reaches the specified threshold or the session ends. Tesla lists 80% and a five-minute grace period, and directs drivers to the touchscreen or app for the applicable threshold. A session still delivering energy can therefore incur a fee. Tesla: Supercharger fees.
That is not the same trigger as the post-session idle fee described for Electrify America's selected 85%-limit locations. Read the screen or app before charging and again when a warning appears; do not borrow another network's grace period. Electrify America: congestion reduction effort.
Check the charging price and any separate parking or access conditions. A grace period is a billing condition, not a plan to occupy a busy bay until the last second. For comparing the whole bill, use our public charging cost guide.
Can you leave the car while it charges?
EVgo says it is fine to leave a vehicle while it is actively charging, recommends locking it and monitoring session notifications, and asks drivers to return when charging finishes. That is EVgo guidance; check your own site's parking and access conditions as well. EVgo: unattended vehicles at a charger.
- Confirm your own session has started before walking away. Check that notifications are enabled, and set a reminder if needed.
- Choose a break that lets you return promptly. If the session stops early, check the alert rather than assuming charging is still underway.
- Move to ordinary parking if you want to stay longer after charging. Ask the host where you may park if this is unclear.
For overnight stops, ask the property whether you may stay connected or must move after charging. Use our hotel charging checklist.
There is no courtesy requirement to leave the cabin while waiting. Whether to remain in the vehicle is a separate vehicle-specific question: follow its charging instructions, and still be ready to move when your session is finished. This is not medical or equipment-safety advice.
Leave the next driver a usable space
EVgo's etiquette guidance includes returning the connector, keeping the area tidy and reporting problems. Make those part of ending your own session, along with checking the session has stopped. EVgo: charging etiquette.
- Park so the designated cable reaches your own vehicle without occupying an extra bay where you can avoid it. If the layout does not work, ask the host or operator for an appropriate space.
- Keep marked access aisles, pedestrian routes and space beside other vehicles clear. Follow the site's signs for reserved or designated spaces; do not assume a particular bay's access rules from this guide.
- Put the connector back in its holder and leave cables as the station directs. Take your rubbish with you.
- If a parked car blocks charging, ask the property staff for help rather than confronting the driver or blocking them in. For equipment trouble, give the operator the station ID and the displayed error.
Our suggested message to staff: “The charging bay at [station ID or location] is blocked, and I can't reach a usable connection. Is there someone who manages this parking area, or another charger I can use?” Share the location and problem, rather than posting someone's personal details.
Know when to try another stop
If there is no clear way to get a usable port, compare nearby alternatives in the US charging directory.
Before leaving, check the actual connection, access conditions and arrival instructions using our five checks for a charging stop.
ChargingStops inventory status does not tell you whether a port is free now. Use current operator information for occupancy where available, and do not assume a nearby pin is reachable with your remaining charge. Venue hours, charging hours and parking rules can differ.
For entry restrictions and payment setup, read charging access and payment.
For operator context and linked locations, browse charging networks.
