You pulled into the Primm Supercharger lot with 18 miles on the dash, a 110F heat index, and the kids in the back. The app said four stalls free. The screen above stall 3B said “Out of Service.” Stall 5A was occupied by a Cybertruck idling with the windows down. Stall 7C charged for ninety seconds and stopped at 4%. The trailer you needed was the next exit south, and you don’t have 90F of headroom to wait for a stall to clear.
A Supercharger stall can be down, full, throttled, or busy. The app shows real-time status most of the time. Sometimes the app is late. Sometimes the stall is busy because someone is camping with a full pack. The right next move is a different decision tree than a Tesla-dispatched tow.
Try the app first
The Tesla app shows stall status. If a stall is marked unavailable, stop feeding it your card. Check a second stall before you unplug. Cabinets share power, so one handle can be busy while the next is free. The published Tesla help is the in-app “find another charger” button, which directs you to the next-nearest stall on Tesla’s network.
If the app says a stall is free but the connector won’t latch, try the connector again. Pull the handle out fully, check for grit or a bent pin, and reseat until it clicks. A connector that never seated on the first try often seats on the second. Don’t keep tapping the kiosk screen. That doesn’t reset the cabinet.
If the stall is full
A full Supercharger lot means every stall is occupied. The most common cause in the Las Vegas Valley is a Sunday afternoon return from California, a Saturday morning strip run, or a holiday weekend. The next-nearest Supercharger may also be full. The published Tesla help is to redirect through the in-car navigation. The Tesla will route you to the next Supercharger with availability.
If the next-nearest Supercharger is in California, that’s a tow-truck ride with a Tesla connector you don’t have access to on a closed gate. Stay on the Nevada side of the I-15 corridor. I-15 toward Primm stays in Nevada. Beyond Primm the corridor is California. The California side has its own Supercharger network and its own FasTrak I-15 Express Lanes that don’t exist in Nevada.
If the stall charges and stops
A stall that starts and stops is a different failure. It can be a hot cabinet throttling. It can be a payment handshake that drops. It can be a connector that didn’t fully seat. The published Tesla help is to try a second stall. If a second stall charges normally, the first stall is the failure. Move.
If every stall starts and stops, the network is the failure. Don’t keep retrying. Read the stall status in the app. Move on.
When the stall failure becomes a roadside call
A Model 3 with 8% state-of-charge that pulled into a Henderson Supercharger and found every stall busy or down needs miles, not a tow. A tow to a working Supercharger is the Tesla channel’s move. A Level 2 charge at the car is the local operator’s move. Both are real choices. The difference is whether you walk back to the car or wait at a Supercharger.
Charge Pro LV is a referral line. We match stranded Tesla drivers with independent mobile EV rescue operators in the Las Vegas Valley. The operator brings a 240V Level 2 source and a NACS connector to the car. They quote you before they start. They bill you directly. A typical session adds about 10 to 20 miles of range. That takes 15 to 30 minutes of charging time. That number is charging time only. It isn’t an arrival time.
Why heat changes the math
The official NWS Las Vegas climate record (NWS Las Vegas / NOAA, KLAS) puts the average July high at 104.5F. About 78 days a year reach 100F or more. About 9.4 days reach 110F. The east valley and downtown pavement can run up to 11F hotter than the rim. Recurrent Auto measured about 5% range loss at 90F. At 100F that rose to about 17 to 18%. AAA’s May 2026 test measured 8.5% loss at 95F. Tesla hasn’t published its own range-loss figure we can cite. So we don’t.
A Supercharger cabinet in 110F heat throttles. The published cure is for Tesla to deploy more cabinets. The published reality is that a 90-second charge that stops at 4% is a throttled cabinet. Don’t keep the kids in the car for that.
What the local operator brings
The matched operator brings a 240V Level 2 source and a NACS connector. They quote you before they start. They bill you directly. They are licensed and insured. The matched operator handles Tesla and every major EV brand. For a non-Tesla on a NACS-equipped truck, the operator carries a CCS or J1772 adapter.
The Level 2 session is enough miles to reach the next Supercharger or your home plug. The published brandStory on the 10-to-20-mile figure traces to the donor ledger and stays unchanged for the Las Vegas Valley. We don’t bundle or split. The bill comes from the operator on scene.
Use the Tesla app and the local number in sequence
Open the Tesla app and read the stall status. If a stall is free, try a different stall. If every stall is down, try the next Supercharger in the in-car navigation. If you don’t have the range for the next Supercharger, call (702) 935-4699. The operator quotes you on the phone. You decide.
If the failure is a stalled session at a working Supercharger, move stalls first. The Tesla app may also report a “stall issue” that Tesla’s own support line can flag for repair. The local operator’s job is miles at the car, not Supercharger repair.

Frequently asked questions
What does a “stall down” message mean?
It usually means the cabinet is offline or throttled. Try a second stall before you move to the next Supercharger.
Will Tesla refund me for a stall that didn’t charge?
Tesla’s published billing rules treat failed sessions as no-charge. Open the Tesla app and flag the failed session. Tesla’s billing system credits failed sessions automatically in most cases.
Can a mobile operator charge a Tesla at the Supercharger lot?
Yes. The operator brings a 240V Level 2 source and a NACS connector. They quote you before they start. The bill comes from the operator.
What if the next Supercharger is in California?
Stay on the Nevada side of I-15. The Primm corridor is the last Nevada exit. Beyond Primm the corridor is California. California has its own Supercharger network and FasTrak I-15 Express Lanes that don’t exist in Nevada.
