Hi.
A little while ago I bought a 12v projector to take camping. I am having trouble running off battery.
The projector is 12v DC. It has a plug pack that outputs 12v DC @ 5A.

Here goes a long story....
When I ran the projector camping it would play for a time and then shut off. When you try to turn it back on it just flashes and stops. (clue1)
So I thought maybe it was getting hot.
So when I came home I did some testing and in the process accidentally mixed the power supply up with a 2Amp supply.
So when I tested it, it did the same. Ran for about 10mins and stopped, flashes when you try to turn it back on.
After going back n forth with the seller I realised the power supply mix-up, connected the 5A supply and it works fine.(clue2)
So now I'm thinking that the issue is voltage/current draw.
So given that I am running off a battery and at the end of a cable run I bought a voltage boost module (6amp).
So at the end of the projector cable I do have 12.4v. I can boost that up to 17v if needed. But the projector still won't run. just flashes.

Any ideas what my issue is?
I don't really understand why the projector won't run at the end of the cable if the voltage reads ok there. It a 4mm twin cable so it can deliver the current.
Just to confirm. The projector will run on the cable even momentarily so there is not connection or wiring issues.
Thanks, Darren.
