AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable Li-ion Battery 150 PSI Portable Handheld Air Pump with 12 V Car Power Adapter for Cars Motorcycles LS40791（C1）

So far we have found this to be a handy portable air compressor. This is both battery powered or can be powered by your cars 12V outlets. This comes with a few adapters to fill balls, bike tires or blow op items like a beach ball, air mattress and such. The battery charges from a USB C type connector. When charging there is a Red LED & when done it changes to Green. The battery does not have a level indicator. When you connect it to the compressor the display will then show in bars how full the battery is. The instruction manual is in several languages. This is fairly easy to use & you can change the measurement from PSI to a few other options. There are also LED lights to help if using in the dark. There are 4 different modes where this will have a pre-set PSI that you can override. When you connect this to your tire & clamp in place for example the display will show the current pressure in the tire. Once you have the desired pressure set simply press the trigger & this will start the compressor. It will run until it hits the desired pressure or maybe 1 PSI more & will shut off. When I ran this on my SUV tire using the battery from 5 PSI to 36, it was slow as expected, ran till the indicator showed 37 & shut off. When I compared to my dial gauge, they were within 1 PSI of each other. The compressor only got warm but the hose was very hot to the touch. Releasing was as easy & placing on & I did not release hardly any air from the tire. This would have been great to have in the car a few weeks ago where we picked up a nail & slowly leaked so we could have topped of the tire a few times until we could get off the highway. This is the main reason we got this now so most of our cars have some sort of compressor in the car. This is not heavy & is more coinvent to use around the house for balls, bike tires Vs dragging out our larger compressor for those little jobs. This will also be great to take along camping for the air mattress or blowing up snow tubes. So far so good this is a convenient little portable compressor that is battery or 12V car operated.

This is a great tire inflater. It comes with a battery, a 12 volt adaptor and a couple of adaptors for inflating smaller objects. The hose has a clamp on type connection for tires. I really like the 12 volt insert, it basically is the same size as the battery and slides into the tool just like the battery and has a long cord with a cigarette lighter type 12 volt plug, so you can switch between the 12 volt or battery very easily and the 12 volt cord wraps around the 12 volt adapter and has a space for the plug to sit in. In the pictures I included you can see the battery on the left and 12 volt adaptor on the right. The inflator itself is digital, so you can change between air pressure units, as well as set a desired target for inflation. I set it to 40 psi and hooked it to one of my tires, which read 36 psi and then pressed the trigger and when it started I set the unit down and it inflated the tire until it reached 40 psi. It has some presets for other tires as well or you can set your own target. It also comes with LED lights in the nose of the the tool which I can see would come very useful in the dark. The battery charges with a USB C charging cord so you could charge the battery right in your vehicle (most vehicles today). This is a superior inflation tool to other hand held trigger units I have used, it is digital, has both 12 volt and battery and hands free. The only negative I would have for this is it is on the larger size and a case would have been really nice. I was really torn as to whether this should be 4 or 5 stars, ultimately deciding on 5 stars, while a case would have been nice, it comes with both battery and 12 volt adaptor, digital and hands free while charging. Other similar big name units can cost $30 - $40 and they dont come with the battery which can add a lot to the cost.
