CPAP power from Data link plug

2023 flhxs....
Im looking to charge my medistrom battery while Im riding that will power my cpap machine while i camp....I want switch power to not drain the bikes battery...Im looking to get a data link wiring harnass that either has an inverter to ac power inline or an adapter that will plug into an inverter and charge my external battery pack...

Preference to the inline as space is limited

Any help would be appreciated????
thnx

How about battery pack? Depending how many nights and how much of it drains.

I mean a battery pack like jump starter. A couple may get you through.

Just read you need to convert your AC. Maybe mount some under your pack. Maybe put something in saddlebag guard bag

Sorry, but connecting something to the data buss that controls the engine and using it as a charging point, is a really bad idea. There are other key on power sources on the bike that wont kill it ,in the event of an issue with whatever it is you are trying to charge.

Either a solar panel or the power plug connector you can install in the tourpak.

Tie in to your aux plug or use a tender port adapter, do not use your data link port.https://www.harley-davidson.com/us/e...ss/p/70264-94A
