Lighter sockets are usually 120 Watts, which if you divide by the voltage will give you a current of 10 amps.
However the BMW ones maybe higher

I think the e70 is 20 amp so e53 may be less ,even with a 10 amp tyre compressor plugged in the plug soon gets very hot I found so I think wiring it direct to the battery and fused would be a better idea.

When my Amateur kit was installed in the E53 it was directly to the battery. I never ran more than 25W input to the antenna(s) on 2m and 70cm in order to keep the risk of air bag triggering or EMI issues with the on board electronics down. I wasn’t drilling holes for the antennas and was wary of imperfect matches via the magnetic mounts in case the VSWR ‘challenges’ upset anything important.

I had a Kenwood TMD700 mounted in the right boot cubby with the control head up front. Speakers were mounted above one of the front trims - above the pedal box from memory.

One day I’ll get round to putting it in the X6.

I’ve never tried HF mobile though as the power levels both drawn and emitted were more than I was prepared to use.

The cigar lighter points should be able to cope with VHF/UHF kit....unless you are putting a stonking great (technical term for lots of power :D ) amp on the output?

I’m not active at present as I just don’t get the time.

Thanks for the replies.
As i thought a battery connection maybe the jump points under the bonnet.
Just got to find a way through the bulkhead not easy for me as i can't bend very well with my disability.

It's a Yaesu FT450d i will be running.
I say mobile but it's just the odd occasion i will take it out up in the hill's.
I run it at 70w on a 30amp psu at home but i don't see it drawing a lot of amps with the meter on the psu but i will try and find a way through the bulkhead.
