DC Portable Air Compressor Pump - Upgraded Digital Tire Inflator with Gauge 140W 150 PSI

Awesome little air compressor. Sure it's not as fast as a huge compressor, but not having to use a separate gauge then having the PSI set to memory more than makes up for it to me. It's as simple as advertised. No need for gauge, and forget about guessing how long to fill then gauging..repeat. If you only use this for one vehicle, you should only have to connect and power on once you set your preferred PSI to memory.I plan on getting an adapter so I can use this inside the home in the rare occasions it's needed for air mattresses, soccer balls ect. I may even try blowing up balloons for the next party we have at home! Either way, this is primarily for my tires both vehicle and z turns and it is easily worth more for that alone...and EASY!!

I have used this unit regularly and appreciate it. It works smoothly and powerfully. It has a LED lamp and LED pressure display for night time use. Note that it is slower than a gas station pump and takes a couple of minutes to inflate a tire to 32 PSI. This unit comes with its own carrying case, so that the attachments (to allow for uses other than car tires) can be stored neatly in the trunk. The unit itself has built in hooks to allow easy coiling of the electrical and pressure cords.

It does work fine, however, the only drawback is that you have to connect it directly to your cigarette lighter port, and leave your car running while you fill your tires up. My car didn’t come with one of those, so I purchased an item that connects from the unit to the plug outlet. It worked that way for about three minutes. I ended up using a friends car so it was a bit of a hassle. I was disappointed that the separate item didn’t work as it was supposed to. But that is not what you’re asking about anyway. I’m fairly satisfied with the purchase of the compact air compressor. Thank you for taking the time to seek out my opinion on your product.

My car has a low tire pressure warning system and every so often, particularly in winter, the tire pressure needs to be topped off. I got tired of stopping in gas stations just to find out that their air pumps were turned off, broken, or missing the tire chuck. Or worse, I'd put the money into the machine, try to use it, and end up letting air out of the tire since the pump was broken. Just used this pump for the first time to easily add about four pounds of pressure into my tires. I set the pump pressure at 32.5 lbs since 32 pounds is the green light pressure for my tires. You turn your car engine on and plug the pump into the cigarette lighter. Setting the pressure is easy, there's a +/- button and a big, easily read led display. Then, and this is important, turn the pump on before attaching the hose to the tire. The 12v motor on this pump does not have the power to start under load and you WILL blow the fuse. (there is one spare fuse in the package if you forget.) Once the pump is running and air is coming out of the hose you screw the hose onto the tire valve. It took 20-30 seconds to add about 4 pounds of air to each tire. The pump turns off automatically when pressure reaches the set point, but the on/off switch (it's a rocker switch) does not turn off, you have to do that yourself and that resets the auto-off feature. I found that the pump setting matched the pressure reading on my vehicle's dashboard. As others have noted, this is not a big pump and it comes in a zippered carry bag. I left it in my trunk. I have no way to predict whether the pump will work ten months from now, and that is always the issue with a tool that is used intermittently. And, obviously, it's not made for heavy duty use.

Everyone with a vehicle should have an air compressor. If you have a tire with a slow leak or tires that need to be filled when it gets really cold you need one even more. I recently had one just stop working so ordered this one... not giving it much thought. How much better could it be? Turns out a lot. I never thought I'd be excited enough about one to write a review... but this sucker is amazing. You no longer need to carry around a tire gauge. It has one built in. You thread it on to the stem so there's no more awkwardly trying to get the compressor clamped onto the stem. You turn it on before you place it on the stem and leave it on while you remove it. No more air escaping while you're trying to place it on/off. It's ridiculously faster than the previous compressor that I had. My favorite part is that cord management is built into the device. It's so nice that even though the one my wife had was still working I bought her one as well.

I've used this pump about a hand full of times over the last 4 months since I purchased it. I was hoping to get a reliable pump for car tires and other items around the house that may need an air pump. Today, I was ready to put it to use for only about the 6th or so time and nothing. The lighted background screen does not even light up anymore even after I checked and changed the fuse. It has no power at all now for some reason. After reading all of the positive reviews I expected it to last longer than 4 months/5 uses. Very disappointed in this product. Will not purchase again and I would not recommend this product to anyone else.
