@Alphin Aloor I switched from Dragon Mart air compressor to Portable ARB which comes with Air Tank.
I installed the electric wire from front to the back, so I can use the compressor as an On-Board one.
Gives me option to remove the compressor and keep it at home if not offroading for long time, specially in the summer.(less maintanance)
I like how I can control the airflow, and compressor doesnt have to run continuously due to Air Tank, however I dont know how it runs without it.
If I had an option to install an on-board one, probably I would do it, but only if I would use the bluetooth option with it.
At the end,if your purpose is just to inflate your tyres, keep the dragon mart one, if you want to make it more easier, enjoyable, and ready to pay for it, get the ARB.
