Slime 40031 Tire Inflator, Portable Car, SUV, 4x4 Air Compressor, Pro Power, Heavy Duty, with Analog 150 psi Dial Gauge, Long Hose and LED Light, 12V, 3 min inflation

This little compressor is great, I have had this for over a year to give it a good test. This works great, you can set the pressure and it stops at the set pressure. It has had no issues even at 0 degrees. I usually warmed it a bit but I can't find any issues with it. I highly recommend this small powerhouse.

I've had several of these Slime tire compressors, and the motor has never has a problem, and this more recent one seems to be a little more efficient than previously. I like the clip-on tire valve stem connector better than the previous Slime tire inflator that had a screw-on tire valve stem connector, which started to malfunctiion after a number of years. One weak point is the tip of the accessory charge plug tends to unscrew and come loose sometimes, creating a spotty connection, or worse fall off, and I've had to search for it in the console compartment, carrying bag or, in this most recent instance on the floor on the side of my driver's seat, and then screw it back on. I'm thinking of adding a touch of superglue to keep that from happening. I've never had to replace the little fuse inside the plug, so... Although this last time I made sure to tighten it as much as possible manually, and I think a second attempt did sinch it up a bit more--I hope that holds it

Very handy and reliable pump.

I used the device to top off one tire, so in total maybe 5 psi has been produced by the unit. That time it worked ok. On the positive side, a rotating collar makes attaching the hose to the tire valve stem easy. Also nice is a little compartment on the compressor that holds (and comes with) different attachments for the hose, including a needle that can be used for inflatable balls, etc. The unit is WYSIWYG and the LCD display is nice, as is the lamp / flashlight on the side.The problem for me of course is that the second time I took it out to use it, it powered on but the compressor/pump would not run, no matter what I tried. The troubleshooting section in the product guide was useless. If the device doesn’t work after only the very slightest of use, and after staying tucked away in its carrying case in a cushioned area and mostly in a temperature-controlled space it’s hard to rate it anything but 1 star. Caveat Emptor.The warranty is 1 year from the Slime parent company, and my unit is inconveniently just out of that period. I have some knowledge of electronics repair so I am going to pop the cover and see what I can do.One other thing: I have a tiny Slime inflator that is about 10 years old and about 3”x3”x1”. I’ve inflated or topped off tires maybe 100 times with that unit and it still runs.One feature that would be nice to have is the ability to plug the unit into a standard outlet, so that it could be used away from your vehicle, or when the keys are not with the vehicle.

I kind of said it all in my headline. I've been using similar devices for years and this is the best of the lot.

Convenient and easy to use. Inflates with reasonable speed.

Works great and is a vehicle must have. I bought 2 and put one in each of my vehicles.

I bought Slime 40030 to replace the old one. This model is analog but I like it much better than the the Slime 40063 Digital model (which I bought for my other house thinking the digital setting is easier to use) because 40030 is light weight and delivers the tire pressure exactly what it shows on the gauge. On the contrary, the 40063 with Digital setting always gave 2 psi lower than what was set. Not a good performance.I am going to buy another Slime 40030, and returning the Digital version, which is by the way almost twice the price.
