I'm thinking of getting a portable tire inflator.

[raccoon]

This week the car kept telling me one of my tires was under inflated, not by much but a few pounds. I went to my local station to add air. It turned out.I had to go home and watch some videos on how to add air using the hoses as they are now. (I hadn’t done it in probably 10 years at least) .But it seemed like such a pain in the butt and I’m about ready to make it simpler and just get me one of those little portable inflators.

What say you, my fellow seniors?

1. Do it.

Better yet, get the kind that also will jump start your car battery. One of the best investments I ever made.

2. I have one

Runs off a battery that I use in other garden equipment. Ok for topping off. Not for inflation that requires a lot of air. Mine has a pressure gauge, but I do not rely on it.

3. Yes. It's also a back up phone charger

They all have a USB port.
Yes you can charge a phone from your car but there’s always the unexpected. We were spending a lot of time in hospitals last year and hospitals are not built for phone charging especially in the rooms.

4. There is 1 in my car at all times,

More uses than just tires, athletic ball, swimming tubes, etc.
And yes, the occasional dashboard warning. It gives a quick air pressure check.

5. I bought one on sale a few years ago

dandy little gadget. It will inflate a small car tire if the bead has not broken but takes a little while. Runs off of batteries that fit my power tools and will charge a phone or an iPad. I mostly use it for bike or garden cart tires and it works very well for the low pressure tires on my Polaris.
There are 2 flavors of inflators so get the variety you need. I have the high pressure low volume variety, it can inflate a bike tire to 100 psi but is very slow on a big tire. The low pressure high volume variety is better for car tires but only inflates to about 40 psi.

6. i paid ninety dollars for an inflator-jumper unit.

The inflator feature of the product I own does not work well with a tire which has lost most of its air. It took a long time to get a significantly under-inflated tire of mine up to the point it was safe to travel on.

If you buy an inflator, it would be a good idea to purchase an accessory cable which will utilize the vehicle's battery as an auxillary source of power for the inflator.

As for tires with slow leaks, I have heard that "alloy" wheels can be the problem. My car has conventional steel wheels, and slow leaks do not occur.

Good luck with you quest for information.

7. I have one and it works but repair tire

I had a tire that kept pulling off a few pounds all the time and I finally took it to a place where they fixed the problem, without buying a replacement tire.

Good luck!

8. I keep one in my car. Preset the psi my tires require, so it automatically shuts off.

9. I've had one for several years. They can have batteries or plug into the car, or both.

You should be able to get one for $40. - $80. that will do the job.
They can also be used for any kind of tire that has a standard valve, and even sports equipment.
I strongly recommend you get one. You'll be glad you did.

10. One suggestion,

get one that inflates up to at least 100# psi or you will be waiting a while.

[bullimiami]

11. You can get a jump pack that also has an inflator plus can be used as a power bank.

Keep one in my car but it’s an older one.

12. Use a bike pump with gauge

A bike pump with gauge makes it really easy to top off tires and zero in on the same pressure for each tire. It doesn't take long just to top off tires especially since you don't have check the pressure after you are done pumping since you can see it right on the gauge. You also get some exercise, nothing to plug in, and it is is quieter than any compressor.

A bike pump with a wide diameter barrel works great.

13. We got one a few weeks ago. It works great. Getting those tire air low messages always freaks me out.

I have a bit of a bad luck streak with flat tires. And now with the portable tire inflator I can inflate all the tires when they are cold which is how it's supposed to work.

14. Maybe beyond your specs, but

I got little Ryobi (you know where to get them, ouch) inflater with a pressure gauge on it. It uses an 18 volt lithium battery, which also fits my portable vacuum and a lantern.

The end kind of "clips" on to the tire valve, so no fussing around.

I can't really say how accurate it is, because I life a half mile up and the outside pressure is only 90% of sea level. Water boils at 207F instead of 212F.
