I've had a similar issue with the female power port, but it was actually the cable in my case. I am currently using it directly with a vps and had no issues since
I dont know if its allowed to post links here. But for Eds WoodScents there is a "Travel Light Controller" available thats basically the chip and a LED dimmer to control the power. This makes the Log kind of mobile. I think thats similar to the way you are heading.

I did not use exactly this one - but I had one lying around, thats looking to be exactly the same (or at least very similar).
