Looking for air compressor ideas

[Ken in Miami]

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.

Great idea. Thanks

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?

I don't know, just read it online Type II has a better pump inside so runs faster and cooler. They're exactly the same on the outside.

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?

As I posted, it runs on all of them individually: battery, cigarette lighter (not in CT) and 110 V to cigarette socket adapter. That's why I didn't go with battery only or AC only inflators.

What does the "ALL" refer to here? Filling four tires consecutively?

All: inflator, battery, AC adapter, wire, connectors.

I use this one. I already have a lot of 18v Milwaukee tools.
https://www.milwaukeetool.com/Products/Power-Tools/Specialty-Tools/2848-20
I tested deflating all 4 tires down between 22 and25 PSI then used it with the XC8.0 battery and it took it down one bar. I went around the truck twice to make sure they were actually back up at 50 PSI.

I use the same Milwaukee unit, very pleased with it.

Most air compressors are not designed for 100% duty cycle. If you pull a trailer with 65+psi tires or ever find the need to fill more than one tire you run the risk of compressor failure when you need it most. This has happened to me more than once before I finally learned my lesson and got this 100% duty-cycle compressor from Viair:
https://viaircorp.com/products/450p-rvs-auto-portable
I have it running off the 48V feed in the frunk via DC-DC converter:

Viair also makes on-board compressors which I assume are the same quality.

For what it’s worth the Dewalt mobile air compressor was the only non-Milwaukee tool I owned and it literally stopped working 2 weeks ago after 12 months to the date. Bought it on a Black Friday deal last year and I guess this year I’ll wait to see if Milwaukee has a good deal somewhere or perhaps I’ll get the Tesla one that’s coming out soon.

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.

That's not a DeWalt tool. But this is: https://www.dewalt.com/product/dcc020ib/20v-max-cordedcordless-air-inflator

I have one and it works very well.

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.

Second the Dewalt. I have it in a hard-case with a battery and USB charger. I put it in the Frunk where I have USB charging ports. I have used it a couple of times on the truck, but maybe a dozen times airing up other tires, balls, etc:

The USB charger connector goes through a bulkhead mount lower-right.

The object in the top-right corner is a jump-starter that runs on a Dewalt battery. I have used that twice, and it works surprisingly well.

Is that connected into the stock air compressor? That seems like it would take forever. I've had mine report overheating for raising and lowering my truck 5 or 6 time in 20-30 minutes (playing around showing people).

Yes it connects to the stock air compressor on the CyberTruck

More power to ya, but I wouldn't tap into a system meant to control your suspension lol

When someone comes out with a more powerful aftermarket one, I'll be looking into getting it if it is setup correctly. If done right there is no danger, it could even be controlled electronically so it doesn't have the ability to bleed if there is a leak or damage.
I personally don't trust the stock air compressor to have enough power to do this in a timely manner and without over heating.

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.

Any chance you have a picture of this in your smugglers trunk? I've been looking for a couple weeks for the right quality high powered compressor to throw in the truck, but I also have my mobile connector, extension cord, and various tie downs in that spot right now so curious for how much room it takes up. I'm a visual learner!

Also paging @Ken in Miami for any pics you might have as well

I bought the Viair with the trailer hitch plug.
my use would be roadside tire repair. It’s small and didn’t take up a lot of room in the trunk. Oh and it’s not expensive. They have all sizes available.

The Dewalt I keep in my hummer with a 6 amp battery and two large cans of fix a flat and tire plugs and no spare. In the Tesla truck Hauling Ass gave the idea for the 120v compressor from Amazon. The problem with the storage bay and an air compressor is height. The Tcbl in original box fits easily I did change the outlet to one that fit all my air lines. I could only find one other compressor short enough to fit and it was a baby Makita with tank from Home Depot. In all trucks I have owned my plan is to repair on vehicle and get to safe location. With tpms I have been able to do a temp repair and keep moving. In reality with this truck or my hummer I just don’t want to carry a spare, passenger car yes.
