If a hotel has only NACS (Tesla-standard) AC destination chargers, a J1772 car can often use them with an AC adapter such as the JT02, but ask the hotel first. Some properties reserve those chargers for guests with specific vehicles or require registration, and some chargers are configured to work only with certain cars. The JT02 is for AC charging only; it must never be used at DC fast chargers.
Key Takeaways
- Ask the hotel about access, fees and adapter rules first.
- The JT02 works only on AC destination chargers.
- Never use an AC adapter at DC fast chargers.
- The car’s onboard charger sets the speed.
Why Asking First Matters
Destination chargers at hotels belong to the property. Access rules vary: some are open to all guests, some require a front-desk code or app, and some are set up to authorize only certain vehicles. Asking avoids an awkward evening and a car that does not charge. It also lets you check whether there is a fee and whether the bay will be free overnight. Read whether hotels have EV charging and whether hotel charging is free.
What to Ask the Hotel
| Question | Why it matters |
|---|---|
| Are the chargers open to all electric vehicles? | Some are restricted or vehicle-specific |
| Do I need to register, use an app or get a code? | Access setup varies by property |
| Is there a charging or parking fee? | Avoid surprises at checkout |
| Can I reserve a charging bay? | Bays may be busy overnight |
| Is an adapter allowed? | Some properties set rules on equipment |
Using the Adapter Correctly
- Inspect the adapter for damage, dirt or moisture before use.
- Connect the adapter firmly to the charger’s NACS connector first, then plug into the car.
- Check the car shows that charging has started.
- Do not leave the adapter where it can be stepped on or driven over.
- Remove the adapter before returning the connector to its holster.

AC Only: Never at Superchargers
The JT02 is an AC adapter. DC fast chargers use different power levels and communication. Using an AC adapter at a DC station is unsafe and will not work. For DC charging on NACS stations, only DC adapters approved by your automaker, and only at stations open to your vehicle, should be used.
Expect the Car to Set the Speed
Hotel destination chargers deliver AC power, and your car’s onboard charger decides the maximum rate. Overnight, most cars gain plenty of range. A typical destination charger running for eight or ten hours can refill most batteries from a low level, so the speed of any single hour matters less than having the bay for the night.
The JT02 is a NACS-to-J1772 AC adapter rated up to 80 A and 250 V AC, with silver-plated copper terminals and IP65 protection.
Frequently Asked Questions
Can a non-Tesla car use a Tesla destination charger?
Often, with a NACS-to-J1772 AC adapter, if the property allows it and the charger is not restricted to certain vehicles.
Can I use the JT02 at a Supercharger?
No. The JT02 is for AC charging only and must not be used at DC fast chargers.
Should I tell the hotel I am using an adapter?
Yes. Asking first confirms access, fees and any equipment rules.
