When you charge a J1772 car at a shared Tesla or NACS charger through an adapter, you are a guest at a charger that was not installed for your plug — and the etiquette follows from that. Take only the charge you need, move when you are done, never touch another car, leave the cable tidy for the next driver, and take your adapter with you when you go. None of this is law; it is the courtesy that keeps shared chargers welcoming to the cars they were not built for.
Key Takeaways
- You are a guest at a shared NACS charger: the host’s permission comes first, and your behaviour is what is judged.
- Charge what the stop is for, move when you are done, and never unplug another car — finished-looking is not finished.
- Leave the cable in its holder and report damage to the host instead of working around it.
- The adapter is yours: it leaves with you, every time.
Start From the Guest Position
A shared NACS charger belongs to someone: a hotel, an employer, a business, a network. Whether you may use it at all is the host’s call, set by their signage and terms — an adapter grants you a fitting plug, never a right to the charger. Within that permission, how you behave is what other drivers and the host judge. Native-plug drivers watch how adapter users treat the shared posts, and hosts decide whether to keep offering access partly on what they see.
The Courtesies That Matter Most
| The moment | The courteous move | Why it matters |
|---|---|---|
| Arriving | Have your adapter in hand before you take the bay, and start promptly | A bay occupied by a car that is not charging is blocked for everyone, native or guest |
| During the session | Stay reachable, and take what the stop is for rather than the whole battery by default | Shared posts turn over on goodwill; a guest who treats one as private parking ends the welcome |
| Another car is plugged in | Wait, or find another charger — never unplug it, finished or not | The session belongs to that driver to end; their car may be locked, scheduled, or still working |
| Something is damaged | Tell the host or operator instead of working around it | A cracked plug reported today is a charger that works for the next guest; hidden damage helps no one |
| Leaving | Return the cable to its holder and take your adapter with you | The adapter is your property — left in the connector it is unattended, losable, and in the next driver’s way |
Small Differences by Setting
- Workplaces. The other users are colleagues you will see tomorrow. The pool of regulars notices whose car sits finished all afternoon; guests on a workplace charger are remembered longest.
- Hotels and hosts. Overnight is often exactly what the charger is for, and the host’s own arrangements rule. Ask rather than assume, and follow the house pattern.
- Public shared points. Stays are shorter and turnover higher. The same courtesies apply, compressed: charge, tidy, go.
One courtesy sits underneath all of them: be at the right charger to begin with. The JT02 is an AC adapter — etiquette starts with never queuing at a DC Supercharger with it, where it cannot work at all.
The JT02 in Shared Spaces
The EVDANCE JT02 is a NACS-to-J1772 AC adapter rated up to 80 A at AC 250 V and sealed to IP65, small enough to live in the glovebox between uses. Nothing about it changes how a shared charger works — it simply lets a J1772 car join the queue on equal courtesy terms.

Frequently Asked Questions
Is it rude to use a Tesla charger in a non-Tesla car?
No — where the host offers the charger to guests, customers or the public, permission is the test, not the badge on your car. Using it courteously, inside the host’s terms, is exactly what the offer invites.
A car looks finished but is still plugged in. Can I unplug it and use the charger?
No. Finished-looking is not finished: the driver may be running cabin conditioning, waiting on a schedule, or about to return. It is their session to end. Wait, or use another charger.
Can I leave my adapter in the charger for the next J1772 driver?
It is a kind thought and a bad habit. The adapter is pocketable property: left behind it is unattended, easy to lose, and one more thing in the next driver’s way. Take it with you — generosity is lending yours while you are there, not leaving it behind you.
