Tire Inflator I’m using

[Alto]

If I'm doing serious off-roading, I'm taking a bunch of heavy-duty gear, including a 120V air pump. For everyday urban use, something more judicious is fine.

That said, I decided to air-down to 36 and time how long it took for my portable unit to get back to 50PSI. After 12 minutes it had only got to 44 and the battery died

There is a post on the forum,
https://www.cybertruckownersclub.co...-kit-accessories-are-coming-from-tesla.16450/
That shows the Tesla inflator for the Cybertruck. Being Tesla the specs are secret. It won’t be available for 4 years. It will be priced relatively affordably until just before it’s released, when the cost triples. It will only inflate the tires to 40 psi. ?

So after fully charging the pump, I went back to get the tire from 44PSI back to 50. I even plugged it into the rear USB-C port with a 6-foot cable that barely reached, which minimized battery drain and kept it at full speed. It took 10 minutes to get to 49PSI before overheating lol.

It might be useful for a quick top-up of a PSI or two, or maybe helping out a stranded Honda, but it's really not gonna have broad application with these tires.

Speed is just a matter of money, how fast can y

I haven't used the product, I could tell by reading the product listing there was no way it was going to be able to air up all four CT tires from 36 psi to 50 psi, or from 50 psi to the towing pressure of 65 psi, without overheating and/or taking forever. I don't have 45 minutes to air my tires back up. The price was the first giveaway, the listing description was the second. The third giveaway was they didn't list cfm specs at different pressures.

speed is just a matter of money, how fast can you afford to inflate?

Your probably much more hard core in off road use of the truck than I’ll ever be. I see my use case as trying not to get stuck in the mud or sand and getting through flooded roads.

I assume that means you want to air down for such conditions. Anytime you need to air down to avoid getting stuck in sand or mud, you need a pump available to air back up. I don't view that as "hard core", it's just reality. That pump needs to be able to add 10-15 lbs. to every tire in a reasonable amount of time (or you will not air down). Even if you are OK waiting 45 minutes, a pump that takes that long will probably overheat or fail.

If you never plan on driving somewhere that requires airing down, then you can get away with a smaller, lighter, less expensive pump for emergency tire repair of one tire at a time. You have to decide before you purchase the pump what capabilities you want.

While it's nice to have a pump that will accurately shut off at the set pressure, you will not find one that is accurate and inexpensive (while capable of filling all four tires in a reasonable amount of time). Another option is to use a hose setup designed to fill all four tires at once and an inflator you have to shut off manually when the built-in air gauge indicates. This is a quality kit:

Amazon.com: MORRFlate Quad 4 Tire Inflation Deflation System | Fits Up to 125" Wheelbase | Includes Manifold, Digital Gauge, and Storage Bag : Automotive

You can make one up yourself from parts purchased individually but, if you buy the same quality parts individually, your savings will be about zero (and you still won't have the handy round storage bag).

This is the one I am looking to purchase for my future Cybertruck. It was also recommended by someone on this forum. Seems to have great reviews and I am a fan of Ryobi products.

Roger, I get your point.

It's not just a matter of money, it's a matter of size, weight and convenience. A compressor doesn't run out and need to be filled back up at a place offering CO2 (they have a fixed capacity to fill tires). A CO2 tank is not exactly light or compact and needs to be kept out of hot enclosed spaces. Also, I prefer not to put CO2 in my tires, it's corrosive to rubber and metal (CO2 and H2O forms carbonic acid), it also leaks out faster. People have gone back to on-board air (compressors) after not liking the CO2 thing.

Sure, it's impressive to fill all four tires super quickly, but to me it's not how super-fast it is, it's whether the system is convenient and reliable (an under-sized compressor is not reliable). I can always find something to do for 15 minutes when airing up (eating, drinking, chatting, organizing gear, etc.) and I'm generally not in a huge hurry, I just don't want to wait forever for a cheap, under-sized inflator that is struggling in the heat of the late afternoon, hoping it doesn't self-destruct.

I have this one in my truck. Bought it because it's dual voltage and can be used to inflate tires or inflatables like an air mattress or beach ball. https://a.co/d/8aLuvI2

Does this fit inside a divided space of the underbed storage?

yep, that’s exactly where I keep it

That Ryobi is in the same class of inflator as the DeWalt 20V Max. Either would work well as an emergency inflator for a puncture, not for filling all four tires after airing down. The DeWalt is probably a little better.

The Milwaulkee 18V inflator fills tires about 3 times as quickly and is the minimum I would recommend for airing all 4 tires back up.

I'm going to try out this cheap 120V inflator ( Amazon.com: Markwort Volcano 120 Volt Air Erupt Inflator : Automotive) and the MORRflate quad hose with pressure gauge (link in one of my earlier posts above). Will report back how it works in a month or so. If I don't like it, I'll find another use for it. I was attracted to its relatively light 5.5 lbs and compact form factor. It's also supposed to be relatively quiet.

Over the years, I've tried various tire inflators, and most of them had to be plugged into the 12v socket in the car. Not the most convenient. About a year ago, on a lark, I bought the Makita air compressor/inflator that uses batteries from my Makita power tools. Wow, what an eye-opener! It is so much more convenient and I don't have to worry about cords, etc. It works reasonably fast too...I still carry some 12v compressors in myvarious cars, but this battery-powered one is what I use at home to inflate tires on a regular basis...

This is the model I'm speaking of:

Thanks for your recommendations. I look forward to reading your review about that inflator. I definitely don't want to regret my purchase.

This is a great thread! Thank all of you for the input.

I’ve used this one without any problems.

https://a.co/d/cLctrTN

I inflate to 65psi for towing and have inflated all 4 in a row without it overheating. I would set it to 65 and let it go on the first while I worked in my boat. When it shut off I’d switch to the next and repeat until all 4 were done.
