Cybertruck Air Compressor + Tire Repair Kit -- User Experience Review

[HaulingAss]

You know, the first place i looked was the user manual and you are right. Its not mentioned in there at all. “Hehe lets make it an easteregg so they feel like they are getting extra features”

Same with my carry-on luggage. The fold down handle is not documented anywhere!

I can't figure out if I should be happy since they included a handle for free, or upset they didn't tell me about it!

I looked at all the options and settled on a Milwaukee M18 inflator. Lacks a light or tray for the cap but it is super fast at the job of inflating tires. It sits in the well with the recovery gear, tie downs and hitch when not being used.

I have the same plus a 4 way inflator hose setup. Shockingly ,inflating all 4 tires is faster than just doing one or two at a time and consumes less battery.
true story.
I think it’s a question of decreased flow resistance vs pressure type situation but I’m no engineer.
Basically I’m reasoning it’s an ohms law type thing relating to air rather than electrons.
Parallel “wiring” results in less resistance allowing the pump to “move” more air per unit of time. Meaning four valve stems simultaneously offer less of a bottle neck than one at a time. Is this correct?
Anyone care to explain this observation in less dumb terminology?

Exactly. The efficiency drops when heat is created. Trying to force a lot of air through one valve stem at a time creates more heat (over a longer time period) than allowing the air to flow more freely into four tires simultaneously. The efficiency filling one tire at a time also suffers because it creates a larger pressure differential inside and outside the tires which forces the compressor to work at a higher pressure (which is less efficient) over a longer time period. So the compressor gets hotter (which is just another way to dissipate energy in a non-productive manner).

The last reason is one reason why it's better not to have a compressor with a reserve tank (it forces the compressor to sometimes work at a higher pressure than that at which the real work is actually be done at).

Totally fake!

No way would Santa lose like that to the Grinch! Especially not on Christmas Eve!

Santa was caught sleeping man.
He was tired. Got sleep Apnea.
Any other day he licks that green meany without breaking a fat-man sweat.
May also be too many cookies. It’s the milk. Makes you complacent.

No there is not!...According to the Manual - there is NO mention of a handle. Perhaps it is a 'field antenna'?. You should put that back down immediately! ;-)

Don’t provoke the fanbois. Remember and repeat “Tesla never makes a mistake or needs feedback”.

You can literally see a handle on any luggage. You could own and use the CT air compressor for years and never know the handle is there. See folks above who own one and insist a handle doesn’t exist. They aren’t incompetent people, and even when using Tesla’s visual instructions you’d never know it was there. Clearly both bad design and bad documentation/user manual. I only discovered it because I held the charger upside down by mistake and it happened to fall down.

I suspect the person creating the Tesla user instructions also never knew the handle is there. It is the definition of a hidden feature, verging on an engineer’s joke - “I wonder how many owners I can fool? How many will be oblivious about this handle and curse the design without ever knowing it was there all along?”

Agree: I would offer the Person designing a vehicle portable tire inflator - SHOULD READ THE MANUAL OF OTHERS - to know what to incorporate in the design and functions. Perform tire repair and inflation in real world situations, perhaps at night...in the rain? so the concepts of handling an AC powered device in the rain - does not seem like the smart idea in the end?

In addition to other engineering, I write documentation for miliary and space hardware. And it *was* important to have the documentation accurate and relevant.

Most manuals now are 'dictionaries' they describe the buttons - but there is rarely any QuickStart or workflow outlines.

Why I think this is important is already there is a terribly low bar with Tesla as far as service, support and warranty coverage. The inconsistencies reported here between Tesla service centers is a clear indication there is no manual / [or a handle on it].

So many on this forum have fallen for Tesla trap of 'Subject to interpretation' which gives everyone lots of leeway and even less accountability.

How are your going to substantiate service and warranty repair issues when there are so many inconsistences even with regards to this silly compressor? Is the fact the AC does not work when charging a warranty issue? - because it not stated to be non-functioning on the CT dashboard controls or CT Dashboard manual?. How hard would it be for the CT dash to state 'AC outlets disabled during charging' FGS!.

...What happens if the inflator handle breaks and you want it warrantied repaired? - they going to tell you there is no handle?

I guess thank God we have lawyers to bring some common sense to this...[We all hate lawyers...because they hold people accountable to what they actually say and do]

Boy, this thread degraded quickly!

It probably won't be the last time Tesla secretly includes a fold-out handle or some other "easter egg" either!

They might just make a tradition of it so they can laugh at the handful of people that take handles too seriously.

So, should I buy it?

1) Does it work awesome?
2) Does it look cool?!

Time to watch the YouTube video.

If you’ve got 600+ dollars burning a hole in your pocket and you like your tire psi to be spot on and you want “cyber themed “everything, then yes. It’s actually a pretty good inflator/deflator. The reality is that there are many products out there that are just as capable and a heck of a lot cheaper.

I’m a newbie so I am pretty obsessed with CYBER everything
The rear bumper protectors were the first Tesla product I wasn’t happy with.
I’ll do some investigation on compressors. The YouTube video said the buttons weren’t that great though…

I felt the same way about my bumper protectors until I wiped them down with this stuff a couple of times.
if you haven’t ripped them off yet, give it a go

I didn’t even put them on! But if the color does change maybe I’ll give them a chance.
