Does anyone carry a portable tire inflator in their car? I'm looking for a high quality 12 volt pump that has decent power, and would appreciate any recommendations. Bonus would be a recommendation for a high quality tire pressure gauge.

My experience is that accurate gauges start at over $50 and go up to around $200 for an accurate digital gauge. The better gauges can be calibrated so they should last a lifetime.I've had a Slime compressor for several years. It has held up well and now lives in my frunk. I have not found a good correlation between price and accuracy in guages. Pick up a few at various places and see how well they correlate with the tire sensors. Of course, there is no guarantee that the sensors are any more accurate. I also have a big $30 dial guageb but I'm not sure it is any better.
\I use this one: Amazon.com: Viair 00073 70P Heavy Duty Portable Compressor: Automotive
Its gauge is crap, but I never trust those on any of them. It does have a screw on tire chuck, so its very nice to use.
What do you guys recommend for a good Slime product to keep on hand?
I 'nailed' a broken bungee cord in the rain on the NY Thruway, and managed to pull off the road before the tire went completely flat. The nice lady at Tesla reminded me that only NY Thruway tow trucks are allowed to operate on that highway, and from my location the minimum charge would be the better part of $300. Fortunately, I remembered the Tesla inflator (slime) kit I'd stowed in the 'lower trunk' . . . it worked remarkably well, and easily took me another 20 miles to the exit and a nearby tire repair shop in Canajoharie NY. And to add to my great good luck, they had a used Michelin 245x45x19, for which I paid $100 installed! The gods were on my side that day.
People need to be cautious about purchasing portable air compressors for tire inflation. Many of them pull 15 or more amps while the Tesla accessory jack is only rated at 150 watts max. 150/12.6 is less than 12 amps. Hence many of these compressors will eventually blow the fuse for the accessory outlet. I just checked and the Amazon Viair 00073 70P being recommended above requires a 15 amp accessory outlet so that compressor is a fuse blower. 12.6 * 15 = 189 watts! Even if you assume 12 volts instead of the nominal lead acid terminal voltage of 12.6, that comes to 180 watts.
Also, always check out the negative feedback on Amazon product reviews to see what people complain about. Sometimes the complaints appear to be real while some are truly idiotic, and everywhere in between. The 70P has some brittle plastic parts that break easily after only a few uses - it sometimes even breaks on the first use. Also the Tesla tire pressures are higher than many automobiles and this model compressor apparently has trouble getting much above 30 PSI, despite the marketing claims that state otherwise.
I have been looking at getting a 12.6 Volt compressor for tire inflation for a recently ordered Tesla and there are *many* that are unsuitable for several reasons, including marketing hype that does not match reality, so read those owner reviews!
Instead of using slime, there are tire repair kits that provide for much better sealing. However, to use them you must have a pair of pliers in the car (easy enough) and be able to move the car to expose the nail/screw or whatever punctured the tire. You pull the object out, paying attention to the angle and the insert a strand of curing rubber that bonds with the rubber in the tire. Here is but one example (this is not an endorsement of this particular one, I have never used it): Amazon.com: Dynaplug 1007 Tubeless Tire Repair Kit: Automotive
Also note that all of these types of tire repair kits are a temporary solution and should be followed up with an inside the tire patch. Some people do not realize that and continue to use a tire with a temporary repair, and then complain when it eventually fails.

The Viair compressors are interesting in their power consumption. Their current draw is based on PSI. My 85P, which is a little beefier than the 70P noted above, will exceed 12A at pressures over 20psi. At 50psi it hits 14A.
