You pulled into a Tesla Supercharger on the I-10 in Phoenix heat and the stall is down or full. The next charger is further than your range will go. I-10 heat drains range, so a down Supercharger becomes an on-site charge call. Here is how to handle it.
Why a down I-10 Supercharger strands Phoenix drivers
Two factors turn a down Supercharger into a real stall:
- I-10 heat. Phoenix averages about 111 days a year at or above 100F. Recurrent reports EVs can lose 20 to 30 percent of range above about 95F. AAA’s 2026 study found about a 10 percent efficiency drop and an 8.5 percent range loss at 95F versus 75F. A car that should make the next charger at 75F may not at 112F.
- Network gaps. ADOT’s NEVI build-out carries about $76.5 million to add up to 69 DC fast-charging sites along interstates, with construction underway in 2026. The build-out is real but multi-year. Today, the gaps on SR-347 between Maricopa and the I-10, on the I-17 north of Cordes Junction, and on the I-8 toward Gila Bend are the longest stretches between fast chargers anywhere in the metro.
A down Supercharger on a hot day is the same problem as no Supercharger at all.
What an operator does at the car
A mobile operator brings a portable 240-volt Level 2 source to where the car sits, plugs in with a native NACS plug, and adds real miles while you wait. A typical session adds about 10 to 20 miles of range in 15 to 30 minutes of charging. That is enough to reach the next working charger you already meant to use.
The truck does not need an adapter for a Tesla. The session is real Level 2 charging at the car, not a fast-charge detour.

How the matching works on the I-10
Charge Pro PHX is the referral line that matches you with an independent local operator. We do not own trucks, employ technicians, or set prices. The operator quotes before any work starts and bills you directly.
The I-10 runs through the heart of the Valley, so dispatch is short and the match is usually quick. The match happens by location and connector. For a Tesla, the connector is native NACS, so every operator in our network can plug in.
For the matching model in detail, see mobile EV charging near me in the Phoenix area.
What to do on the freeway shoulder
Get the car as far off the travel lane as you can. Keep hazards on. ARS 28-871 says to leave the traveled part of a highway when you can. A vehicle that cannot be moved is exempt.
Have a location ready: the nearest exit number or cross street. The closer the pin, the faster an operator can find you.
Stay in the car if that is safer. ARS 28-775 is the Move Over law. Approaching a stopped vehicle with flashing or warning lights, drivers must move over a lane if they safely can or slow down.
If you can exit and pull into a side street or shopping center, do that. Off-freeway stops are easier for the operator and safer for you.
What DPS and ADOT will not do
Arizona DPS Roadside Motorist Assistance and ADOT’s Incident Response Unit are the two free motorist-help programs in the Valley. They change tires, bring gasoline or diesel, jump conventional batteries, and clear debris. Neither program advertises bringing an EV a charge. That gap is exactly what an independent mobile operator fills.
For the wider rundown, see Tesla flat tire coverage and the Arizona motorist help gap.
When a tow beats a charge on the I-10
A tow is the right move when the traction battery has a physical fault, when the car will not wake after a 12-volt jump, when the charge port is damaged, or when the operator cannot safely run a generator on the freeway shoulder.
For the wider principle, see mobile EV charging vs a tow.
What to do if you are stuck on the I-10 now
If your EV is dead on the I-10 right now, get the car as far off the travel lane as you can and keep hazards on. Have the nearest exit number or cross street ready.
Call (602) 932-0920. The operator quotes before any work starts and bills you directly.
Frequently asked questions
What should I do if the I-10 Supercharger I needed is down?
Get the car as far off the travel lane as you can. Keep hazards on. Call a mobile operator who can come to you with a Level 2 source and add range to reach the next working charger.
Will Arizona DPS bring my Tesla a charge on the I-10?
No. DPS Roadside Motorist Assistance and ADOT’s Incident Response Unit change tires, bring gasoline or diesel, jump conventional batteries, and clear debris. Neither program advertises bringing an EV a charge.
How much range does a freeway shoulder mobile Level 2 visit add?
A typical session adds about 10 to 20 miles in 15 to 30 minutes of charging. That is charging time at the car, not travel time for the operator.
Does Charge Pro PHX cover the I-10 in Phoenix?
Yes. We match you with an operator who serves the corridor. The I-10 runs through the heart of the Valley, so dispatch is short and the match is usually quick.
