Barstow Supercharger

I travel frequently between Camarillo and Las Vegas. The Barstow Supercharger is key to my success in making the trek in a timely manner. I have noticed that on numerous occasions there have been as many as seven (7) Tesla's there. The problem. There are only four (4) charging stations. Secondly, when all four are taken, the charging to the vehicle can be as low as 75 miles/hour. Not a Supercharge at all.


Build more Superchargers in this location with higher capacity to charge at the 285+/hour. Primm will not help me, as I will never make it from Camarillo.



Excellent point.

By the way, what time and day of the week that you've experienced wait at Barstow Supercharger.

I asked this in another post, but are there still chalk line indicating that Tesla might expand to more bays in the back of that parking lot? It looked like chalk lines for at least 6 more spots...


Sam, thanks for the post, I am moving to Oxnard, on the harbor, and will have an even longer drive to Barstow. I did not know that the more vehicles that are charging the lower the charging rate, that is crazy.
That is the first time hearing of that, has anyone experienced that at other stations?

Like Tam asked, what days do you normally travel to Vegas and back?

NKYTA, I hope that you are right and I will check when I go up soon.

Just tonight was discussing this very SuperCharger. As a guy who has been going to Las Vegas since 1958 (actually Lake Mead) and who used Barstow twice last week, I saw the very problem you are experiencing. LA to LV and back is one of the heaviest traveled, touristy (touristie) freeways in the country, especially on week-ends and especially on three day holidays. Barstow will NEVER work until many, many more stalls, with lots of power are installed. And worst of all, they have somehow steepened the Baker Grade from Primm to Mountain Pass.


It's well known, but if your Delivery Specialist doesn't inform you then you'll have to find out the hard way in real life.

Maximum kW / used bays

Each supercharger is usually hooked to 2 bays.

Such as Bay 1A, Bay 1B.

1 active car charging in bay 1B then that car gets 120 kW maxium.

If then there's another car just drove in and hooked to bay 1A, then the maximum kW that each could get is 120 kW / 2 = 60 kW.

Was at Barstow today and it was truly a shit show.

All 4 bays were full when I arrived. Two more people arrives 10 minutes after me so there were three of us waiting.

Charging speed never got over 195mph and it's making this trip a bit difficult.

Please Tesla.

It could be that it's only busy during tourist time and idled most of the time.

In that case, the Engery Delivery may not show that it's so busy and hell. It may show that total Barstow usage is even less than Oosterhout in the Netherlands!

Thus, you need to tell Tesla not to look at total energy usage but also at owners' real experience.

Thus,if you could all please officially document your experience to:


Hell with the Delivery Specialist, this needed to be explained during the sales process when they where raving about charging 150 mile in just 20 minutes.

These charging stations are looking more and more like the weak underbelly for Tesla.

#1. Charging time goes up when more than one car is charging!
#2. Not enough stalls for busy routes!
#3. Equipment in disrepair!
#4. ICE cars parked in charging stalls!
#5. Cars that are charged, owners are absent!

I know that it is free, but that was always included in the sales process and literature.
Tesla really needs to figure this out, you have 30,000 owners depending on these.

I for one would pay what is needed to hire a valet at every station, to jockey cars and maintaining equipment.

This is the funniest post in a long time. Thanks for the belly laugh.

I need a new job. Valet in Barstow. Really fits my skill level. Will work for tips, and wash your windows too...

But will you wax my car?

Not bad Burt. The only valet gig with a $100K application fee.

Tesla has extensive SuperCharger data logs. If the Barstow site is chronically oversubscribed, they will definitely expand to meet demand. This is a high profile route.

Do all of you think more stalls at Barstow is the top priority, or would you rather have another site first that splits the distance?

Barstow upgrade is definitely overdue. It's one of the oldest SCs on one of the most traveled routes in the country. AND the distance between Barstow and Vegas kinda dictates that you have to hang around for a long time to get enough charge since there's no SC in Primm yet :(

Tesla people problems...

Sounds like they need more and faster superchargers. Would be a great place for the 135kW superchargers - or even larger. Since it is shared with two stalls, and at peak times most chargers are shared, seems like a good thing to do.

Simply replacing the existing 90s with 135s is a 50% increase - assuming there is enough juice and all cables are large enough this would be a pretty simple swap (my guess is it will not be that easy unless they were planning on larger SCs when they did the install).

Possible location for battery swap?? Would be a nice buffer for the grid - sort of hard to charge so many batteries in 6 hours on Friday, and 6 hours on Sunday. But if you swap your battery on the way to Vegas, they have 36 to 48 hours to charge all the batteries over the weekend while people are in Vegas instead of 6 hours. And the bulk of the charging could be during low usage times, instead of peak Friday afternoon/evening time.

My Opinion is: With LA and Orange Counties so large, another location for chargers would be in order. Baker is too far going north, Victorville going south. Maybe a SUPER SUPERCHARGER with a car wash and valet parking(I still need the job) A 90 second battery pack exchange would work...

Hey owners thanks for the feedback and comments. I am sure glad I'm not the only one experiencing the issue at Barstow.

I agree with many of the comments. The route between LA and Vegas is a major one. Help us all when the Model X comes out. It will be insane. I've said it before, if I pull in and there are 12 Tesla's waiting to charge, I will charge my car, turn around go home and get another vehicle.

I understand there are growing pains with a new technology, but there is only so much I will put up with. I love my Tesla, and want to enjoy it for the years to come.

Again, the 135kw idea posted by tes-s sounds sweet. As I really only need 200 mile rated range to get from Barstow to Las Vegas and Barstow to Camarillo (Oxnard mover, you will have no issues - Camarillo to Oxnard is only about 10 miles max).

For some of the other questions about when I am there. It really depends. Typically, Friday between 1 pm - 5 pm PST, and Saturday between 5 pm - 7 pm.

Although this last trip I stayed an extra day and was there around 9:30 am (4/13/14). That was a nice charge because I was in the bay with the Supercharge #28 and was getting 285miles/hour.

The total charge time from 30 miles to 211 was around 40 minutes, which is pretty good. I really only need 190 miles to make it home, albeit it will push it close. 211 was plenty, and pulled into the driveway with 30 miles to spare. That's going 70 - 85. If you push your P85 to 120+ forgetaboutit, and all bets are off!

Thanks to all and will check back soon.


Lots of complaining here, but it does look like Tesla is working on it. They have a SC planned for Primm, NV.

+1 @shop, but I don't think this is so much complaining as discussing. My bet is Tesla is all over this one - my guess is Primm, expansion of Barstow, and probably working on at least one other location.

I'm not sure that the division of power in Superchargers is equal. It is my understanding that the S/C's are in pairs, but the first car in gets the lion's share. When the first car is nearing full charge, the charge slows down and the second car gets more and more.

I had to use the Barstow supercharges the weekend before last. I arrived both coming and going with one bay available. There was no one who came while all the bays were full. I got there at 1:30 on Saturday afternoon and about 4:00 on Sunday afternoon.

If the Barstow is truly a problem, then maybe when you arrive to see waiting cars, a call to ownership will let them know that there is an insufficiency there. Tesla usually responds to our needs.

I'm guessing Primm, expansion of Barstow, and possibly one between Barstow and LA.

So travel choices would be
LA - Barstow - Vegas
LA - Before Barstow - Primm - Vegas
LA - Before Barstow - Barstow - Primm - Vegas

Thinking second would be quickest, because of not having to charge to max.

When X comes out, SC's will be 10 miles apart.

I live in Carlsbad. It is 269 miles from my house to Primm on the 15-215-15 route. Even if they put a SC in Primm, I'd still have to stop in Barstow (I have a S85 on order). Not sure where another spot would make sense. Riverside or San Bernardino or Victorville?


Looks like we have to go on Tuesday, Wednesday or Thursday, and avoid the week end.

Luckily I arrived at the Barstow SC about 11AM Sunday on the way home from Vegas. When I arrived there was one other car finishing charging. Then a Volt showed up but could not connect (obviously) so he left. We went to one of the local restaurants for 30 minutes and when we came back, all four bays in use and 2 cars waiting. I left my spot right away to let the first waiting car in. This was my first experience using the Barstow and Vegas SC's for a weekend trip. It worked well for us but I could see that charger getting very busy on a holiday weekend.

Do people leave a card or piece of paper with a mobile phone number on their windshield while charging at an SC? I'd probably do this in case the bays fill up. A waiting MS owner could call me to let me know so I could move my car out of the spot for him/her if I am done charging.

I guess the other option would be to move the car once the app tells you it is done. Be nice not to have to do that though if all the spots aren't full.

Question from a potential MS 60 owner, I assume the SC network will be expanded/upgraded as more Tesla's are sold?

I sure hope so.
Some here have said that new installations have slowed down, let alone upgrades. I am to new to know, but hope that that is not the case.

I and a brother and 1st cousin begin a coast-to-coast trek (3 very young 70ish geezers) from Dunlap, CA (Fresno area) on May 10. 1st day will be SC stops at Tejon Ranch, then Barstow, then Vegas for 2 night stay to begin the trip.
Figuring 4 1/2-5 hours to Barstow from Dunlap, are there any recommendations from those with Barstow experience as to when the best arrival time for SC on that Saturday would be? I realize there are no guarantees but we are flexible with our start time and would like to optimize our timing. Thanks for any advice...


I always leave my cell phone on windshield when I leave my car charging.

I seldom see other owners do. But I've seen a very few do.
