With so many experts on this Forum, we are hoping for a solution to our problem which is if we can charge my wife's portable Inogen Oxygen machine while we are riding?

Wife has a light weight Inogen Oxygen producer and we have a car charger adapter we use in our car to charge the unit. It takes a 25 amp fuse (we had to increase fuse amperage from 20 to 25 amps for the unit not to blow the fuse) to charge the unit. Is there any solution to this problem using the Spyder trunk charging unit or does anyone have another solution? Believe trunk charging unit is supported by a 5 amp fuse which makes it useless for other than charging a cell phone. We have a 2016 RT L SE6.
