Dewalt cordless inflator. Keep a battery charger and 2 batteries in the vault under storage.

Also have a Dewalt electric chainsaw. Necessary for forest living.

I have the larger Dewalt Inflator. It handles the 20v batteries, 12v cig plug, and 110 volts if you get the optional inverter. There are some knock-offs on Ambazon for half the price. The specs state that it can run continuously for 30 minutes. It is 75 decibels, but fills tires just fine. The smaller dewalt, posted above, has lower capacity, pressure, and run time.

- I got this Dewalt inflator TYPE II for $79.99 at Lowes after price matched a store online.

- And two Dewalt batteries and charger at Home Depot for $94.74 after "Hack": 6.0AH and 4.0AH. and charger.

- Finally this AC adapter for Dewalt inflator for $17.99: AC to DC Converter, 100V ~ 240V to 12V 10A 120W, Car Cigarette Lighter Socket AC/DC Power Supply Adapter Transformer for Tire Inflator, Car Refrigerator, Car Vacuum Cleaner, and Other Car Devices

I tested all with good results then put them in the trunk.

- Test 1: using 4.0AH battery to inflate 4 lbs to 57 lbs in ~25 minutes. Still got 2 bars left on battery.
- Test 2: AC adapter from 6 lbs to 57 lbs in ~30 minutes.

Both tests are just a very little warm to touch on ALL of them.

That unit is a little slower but it is more compact...
Agreed. It's slower based on a man with both inflators testing side by side on youtube. BUT he tested the TYPE I, no testing TYPE II and Milwaukee I can find online.

I almost went to the Milwaukee for speed but finally I got Dewalt Set: it can run on battery, 110V AC, cigarette lighter (not for CT) and small enough to put in the trunk.

I had the 20V Dewalt inflator before I bought my Cybertruck. It's a solid little rechargeable inflator for adding a couple lbs. per tire, but it's completely unsuitable for airing up all four Cybertruck tires after deflating for off-roading. I still have the Dewalt, I added 2 psi per tire to my CT tonight with it, it works fine for that (but slightly slow).

But, no, don't try using it to add 15-20 psi per tire, it's not made for that.

I've been using this for 7 months and it kicks some serious ass (and fits in one of the side compartments in the Cybertruck's Smuggler's trunk):

Amazon.com: TC·BL Portable Air Compressor 110V,Ultra Quiet Air Compressor Oil Free and Lightweight Small Air Pump : Tools & Home Improvement

I use it with a 4 way hose so I can fill all tires simultaneously. Only takes 4 minutes. The DeWalt, if it didn't thermally shut off or burn up, would take an hour or so. But I suspect it would shut off (thermal overload) before it raised all of them 15-20 psi.

I don't recommend the TC-BL compressor without a 4-way air hose. It will work but it's far from optimum because Schrader valves were never designed to flow enough volume to fill 35" tires in a reasonable timeframe.

That little yellow and black pistol grip inflator pictured above? I don't think it's a DeWalt, and no, it will be complete junk in this application. I doubt it would even do it one time.

I don't know you have Dewalt inflator Type I or Type II but if you read my post Type II runs non-stop for 30 minutes from 6 PSI - 57 PSI just a very little warm to touch for 1 tire. I did not test non-stop all 4 tires though.

I bought a 120 volt compressor at Harbor Freight and strapped it up front in the bed with a 25’ extension cord. This way I don’t have to worry about weather a small compressor battery will still have a charge after sitting for a period of time. Also it will pump up a tire pretty fast.

My DeWalt inflator is the Type I. It's never shut off due to thermal overload, but I've never used it to add 15 lbs. to every tire in a row. That would take forever and cause undue wear on the inflator. It's a good little inflator, but it's not made for filling multiple 35" tires in a row.

The unit I linked to that's the same size as the DeWalt fills all four tires simultaneously, in only 4 minutes, after airing down to 35 psi.

I had the 20 V Dewalt before I got the Cyber Truck due to having many batteries for it. I keep it in my Hummer and after deciding that the Cyber Truck was going to be my vehicle for my 100 plus miles crossing the Everglades several times a month at night, I took Hauling Ass's advice on the TC-BL compressor to keep in the Tesla truck now. The storage compartment in the bed of the truck is not very high so the compressor had to fit in there. Not many will. For my use I needed one for the same reason as my Hummer, fix tire in place on vehicle as I do not carry a spare. The TC-BL does ger hot when adding air to just one tire but much faster than the Dewalt. I also bought a 25' 16 ga extension cord to keep with it to make it a bit easier to reach the front tires. Works great off of the trucks electrical outlet in bed of truck. I did not find a small compressor that would fit in the storage compartment with a reserve tank. I wonder what Teslas compressor will be like.

- I got this Dewalt inflator TYPE II for $79.99 at Lowes after price matched a store online.
The listing you linked to doesn't designate whether the buyer will recieve a "Type I" or "Type II". It looks just like my DeWalt inflator. What is the specific difference between the two types?

- And two Dewalt batteries and charger at Home Depot for $94.74 after "Hack": 6.0AH and 4.0AH. and charger.

- Finally this AC adapter for Dewalt inflator for $17.99: AC to DC Converter, 100V ~ 240V to 12V 10A 120W, Car Cigarette Lighter Socket AC/DC Power Supply Adapter Transformer for Tire Inflator, Car Refrigerator, Car Vacuum Cleaner, and Other Car Devices

I tested all with good results then put them in the trunk.
You've already spent more than the more powerful, more robust inflator I linked to above. And it can be left in the trunk, even during cold or hot weather. DeWalt recommends storing their inflator indoors, away from cold and hot conditions, probably because it runs on batteries. Li-ion batteries do not like to be frozen or baked in a trunk. Can you at least run the AC converter without the battery installed? But why not just buy a unit that runs on A/C natively?

- Test 1: using 4.0AH battery to inflate 4 lbs to 57 lbs in ~25 minutes. Still got 2 bars left on battery.
- Test 2: AC adapter from 6 lbs to 57 lbs in ~30 minutes.
From those numbers it looks like it would take around an hour to do what the TC-BL does in 5 minutes. Listening to an inflator for an hour every time I finished 4x4ing would drive me absolutely nuts! I would NEVER air down if I had to refill using the DeWallt inflator.

]Both tests are just a very little warm to touch on ALL of them.
What does the "ALL" refer to here? Filling four tires consecutively?

The TC-BL gets hot when filling only one tire at a time (if you don't turn it down to 50% speed) because it flows so much more air than a Schrader valve is capable of flowing. That's why I recommend filling all tires simultaneously with 4-way hose, or turning the compressor down to 50% power if filling one tire at a time.

What happens is the pressure between the inflator and the tire valve rises to a very high pressure, even if your tire is completely deflated or has very low pressure in it. That means the compressor is doing far more work than is actually being accomplished (due to the restriction in the Schrader tire valve).

Rather than an electrical extension cord that might cause your inflator to get hotter than necessary, you want an extension air hose so the compressor can remain on the tailgate.
