Review on 🔋 Rechargeable Cordless Tire Inflator - Portable Air Compressor Pump for Car Tires, 150PSI Digital Pressure Gauge, Auto Shut Off, Includes 12V Car Power Adapter by John Raj

The product inflated and deflated automatically and was accurate to within 1lb or pressure compared to my other digital gauge. This should work fine for bikes and medium sized car tires. I don't think it can inflate big truck tires very well, otherwise you have to stop constantly to keep the engine cool. However, it can be used to inflate large tires. The cable length is suitable for most vehicles, but larger, full-size trucks will find it difficult to reach the rear wheels unless the valve is facing forward when the tire is spinning. If the cable was 3 meters longer it would be much better.
