      Someone said “this portable tire inflator is designed to inflate normal-sized car tires and bike tires. It is not powerful enough to inflate large tires, like dirt bike tires.” So if can can fill a car tire why not a dirt bike tire?

      Answer This Question

      Hi Layla, the L7 tire inflator may not be powerful enough to inflate high-pressure tires. It can work when your tires lose a little air, but it hardly helps if your tires are flat. You can choose our L8 bike pump, which is specially designed for bikes.

        Is the 30-36 psi in under 1.5 min inflation time starting from 0 psi or is it saying it takes that much time for the 6 psi difference between 30-36 psi for the referenced 195 tire?

        Hi Damian, this tire inflator refills a 195/65R15 tire from 30 to 36 PSI in 1.5 minutes. It takes that much time for the 6 PSI.

                  Nice Little Pump!
                  I picked up the AstroAI portable air compressor while searching for a reliable, compact inflator, and it has already proven itself useful. I often go on long bike rides and occasionally need to inflate my tires out on the trail. This little compressor has been a great companion! So far, I’ve used it on three bicycle tires—two of them completely flat—and it handled all of them with ease, inflating much faster than I expected. One thing to note: the included needle valve for sports balls wasn’t a perfect fit. I had to tighten it onto the Quick Connector with pliers, and even then, I could still hear a bit of air escaping. I swapped it out for the needle valve from my old bike pump, and that one fit perfectly with no leaks. I also appreciate the built in USB port, which lets you charge a phone or other small devices in a pinch. Overall, this is a solid, reliable tool to keep on hand, especially for cyclists or anyone who needs a dependable portable inflator.

                  A small, fine piece with obstacles.
                  Actually, I could love this little gadget. It feels good, looks modern, and can be used as a backup battery and a fancy emergency light. And yes, it can also be used to inflate a tire. I first tried inflating it from 22 to 35 PSI. The tire is a 235/65R17 on my Volvo. It works amazingly well and the compressor stops after 7 minutes. I checked with another pressure gauge and yes, the 35 PSI is correct. Now the device is fully charged again. My second attempt was to inflate a tire from 5.5 PSI to 35 PSI. This went really well until, after about 12 minutes, the compressor stopped at 23 PSI because the battery was empty. No one wants this to happen, but with such a small design, it should be clear that this is the case. Another positive feature of this device is that the cooling system really works. It never got hot to the touch, only the hose got almost hot. I don't think this device can fully inflate a real truck tire. It may be sufficient for a regular SUV tire, provided you're not starting from completely flat, as I was. And if necessary, you can always connect the charging cable to the compressor from somewhere in the car.

                  Very handy tool for the right jobs.
                  This little pump is perfect to keep in my truck. It is smaller than I expected. The footprint is smaller than my iPhone. The compressor function works great. I’m not sure that it has enough battery capacity to be inflate a totally fat tire, but it should certainly be able to raise the pressure when you get the low tire warning at the onset of cold weather. I plan to use it for pumping up bicycle tires and for inflating the overload airbags in my truck when I’m pulling a trailer. It is idea for those tasks. The pump also has a light function and a Type-A USB charging port for charging other devices. I’m giving it 4 stars instead of 5 because the charge rate is very slow. I also would prefer a lever-lock for the air pump instead of the threaded connection, but that is just personal preference.
