No, this must be operated via the 12v cable. Whilst it could arguably be handy to plug this device into the mains socket, it would mean having a transformer added to the device - would increase the cost and weight.

No, only 12 volt cig lighter connection, but that's what you're likely to find with all of them.

No it does not come with an AC adapter unfortunately. Good unit all the same.

Yes, this inflator is operated via a 3.0m long cord with a fused 12v power plug which plugs into cigarette lighter socket.

Yes!

Yes the inflator comes with only a cigarette lighter plug

Yes absolutely - it is the only way it can powered up,

Yes, this model does have a cut off facility.

Yes, it switches off when it reaches the pressure value that you set.

It does not remember a value or the choice of working in psi bar, forgotten each time the power is disconnected, which is a bit annoying

Yes it does stop the compressor once the measured pressure achieves the desired pressure (you set the latter).

Yes, accurate to ±1psi up to 50psi; pressue can be set to 300psi but Ive no way of knowing what would happed if you tried to go that high.

As far as I remember the max psi was 140

This inflator can handle pressures up to 50psi

Should not present a problem (should go up to 100psi).

LEDs usually last a very long time & in my opinion (Electrical & Electronics engineer) the LEDs will outlast the comppressor unit.

First of all I expect they will outlive the compressor.

Second you will need to be handy and will need to source replacements and solder them in-situ.

In a word - yes!

Yes; I'm pleased with it.

First of all the weight of the vehicle is irrelevant in this construct.

You will be unikley to be going from zero to 70 on all six tyres so assuming you are topping up on average by say 10psi - I would venture that the compressor will have sufficient rest time in the dwell as you change from tyre to tyre.

12volt

It can go up to 50psi
