Review on 🚗 Kensun Model J Portable Tire Inflator - AC/DC for Car 12V DC and Home 110V AC - Air Compressor Pump for Car and More Inflatables by Rodney Harris

I bought these to replace an old bike pump. I thought it would be perfect, but I think it has the following disadvantages: 1. The air hose is very short. If you have a bike tire with a valve on top for easy access, the inner tube won't do.2. The hose connector is screwable and seems to leak no matter how tight you screw it in. It can read 35psi and it seeps up to 26psi instantly. I've tried several times to fix it but to no avail.3. I used the AC jack which is external. Short but you need to use an extension cord. The problem is that the DC plug for the car is on the bottom and you have to flatten it every time to keep the pump flat on the ground. Too bad the take off wasn't easy.4. I set the pressure to a certain level and the pump has a habit of shutting off at random times. In general it was a good idea, but poorly implemented in my opinion. The human factor is always important. I returned it.
