Tire Inflator Portable Air Compressor, 150PSI Smart Air Pump for Car Tires with Battery x3, Auto-Off Pump with Digital Pressure Gauge & Extended Air Hose for Car, Motorcycle, Bike, Ball

This is a lovely pump, well designed with a nice user interface. The pump comes with a 12” long flexible hose and rubber bumpers that allow the pump to stand vertically for good visibility while in use (and the bumpers also protect the device case from bumps and scratches during use). There is a small storage compartment in the front to store the small inflating adapter accessories. The pump can be used in a car if the batteries are low with the enclosed cigarette lighter (DC 12 V) cable. So, if you, like me, put this in your car, you don’t have to worry if the pump batteries have not been charged recently.This pump is aimed for many uses – auto tires, bicycles, sports equipment and other inflatable devices. I wanted it primarily to inflate the tires of my bicycle. The developers of this pump should have spent some time and space in the User Manual explaining how to use the device to inflate bicycle Presta valves (called ‘French’ valves in the User Manual). For those who have never used an inflator with Presta valves, you need to first open the Presta valves by turning them, and then screw on the adapter to the threaded valve stem. The end of inflating hose end then fits over the adapter, and then the lever of inflating hose is closed. There was nothing about this in the User Manual.

This is an excellent little air pump, and I can confidently say I’ll never go back to using a traditional wall plug or cigarette lighter plug pump. The portability and convenience this offers make a world of difference.Being able to carry this pump around, hook it to a tire, set the desired pressure, and let it handle the rest on its own is a huge upgrade. The old method—untangling long, cumbersome cords, dragging them to the tire, watching the gauge, or worse, removing it to manually check the pressure—feels outdated and unnecessarily complicated by comparison.The fact that this pump operates without needing to be plugged into a power source is another big advantage. It’s perfect for situations where you might not have immediate access to electricity.It also includes a light, which is a nice addition, but the output isn’t very strong. I’d love to see future versions with a more diffused light, like a pool light, that could better illuminate the tire during nighttime use. The flashlight-style light is functional but limited.Overall, this pump is a great product that simplifies a frustrating process. I can’t imagine going back to the old way of inflating tires after using this.

This Smart Air Pump/Compressor is a cut but effective tool to have on hand when you need an emergency tire fill, be it your car or your bicycle. this air pump/compressor can deliver up to 150 PSI & is rechargeable. It delivers a lot of power for a unit that's so small. it also comes with many bells & whistles including a front bottom storage unit to hold the nozzles. The LED screen display can be preset to a fixed amount of air, or you can visually follow until you get to your desired air input. There are 5 inflation modes on this unit & the directions are easy to follow. There is also a SOS/Strobing flashlight on this unit should you need a tire change in the evening when it's dark outside. It also comes with a cigarette lighter adaptor so you can charge this while your car is running, for extra power.The USB charging ports are easy to access & the unit charges quickly & holds a charge for a decent amount of time..I highly recommend this portable Smart Air Pump/Compressor & I gladly give this unit a 5-star rating!!

This is basically a very nice pump. Out of the box it looks and feels very nice. I have pretty small hands and this is easy and comfortable to hold. Generally all I've used this for is topping off my tires regularly. Bringing my sedan's pressure up four pounds took about 40 seconds. Topping all four of my tires-a couple of pounds in each-left the battery with three bars down from the four when fully charged.The pump has several programmed pre-sets for average pressures for different items. And if the pressure needs to be adjusted the controls are easy and straightforward. Which brings me to my main caveat. The controls are virtually impossible to see in broad daylight (see photo). In order to set things up I have to open my trunk and set them in the relative darkness there. Now at night this shows up great and there is a well placed, bright LED that helps to see what you're doing.A couple of times I've had to push on the power button twice to turn the unit on. I'm not sure if I didn't hold it down long enough or perhaps too long? But at any rate this is not to my mind a big issue and as mentioned is probably more a matter of touch than anything else.The nozzle clamps securely on the tire valve. Easy on, easy off. There are various adaptors for different types of valves in a hidden storage area.Oddly one of the little touches I most appreciated they didn't even show in the ad. There are two rubber bumpers included. These slip on the top and bottom of the unit. So when I set it down on a rough surface the pump itself doesn't get scratched. These can be seen in my photoThis comes with a USB C charging cable. And more importantly a connector for the car's cigarette lighter. So if the battery is dead or low just turn on your car and plug the pump in.I carry this in my trunk and I love the security of knowing I can pump up my tires at any time with out having to drive around looking for a pay air pump. Very satisfied.

The battery is pretty good on this thing. It's nice to keep in your trunk of your car. You never know when you are going to need to add a little air in your tires and there is nothing more annoying than trying to refill at a gas station. Seriously, cars should come standard with this battery tire inflator. I like how it also has a 12v plug if you want to run it off the car for backup power. It's a great buy.
