Impress with this tiny air pump. It's small and lightweight but also comes with a powerful motor. Tire Inflator can inflate a electric bike tire from 0 to 150Psi in just 30s. You can check and inflate all 4 tires in less than 5 min. The digital display is easy to use, allowing you to change the pressure units and value. It also conveniently comes with both AC and DC power options. The DC cord is sufficient, but I had to pull the air pump through the driver's side for the two left tires and then move it through the front passenger's side for the two right tires. Other than that, it's a great device that I would recommend to ensure your tires are well inflated. It also comes with attachments for basketball and bike tire inflation, which is a nice little bonus.
