Heated tube for Resvent iBreeze?

I've only been using CPAP for a few months. Now it's cool-weather time of year here in the northern hemisphere, so I've just encountered condensation in the hose. (Aka rainout -- if that's not the same thing, someone please correct me.) The obvious solution is a heated hose, to keep the temperature of the inside surface of the hose above the dew point of the humidified air. But it looks as though heated tubes normally get their power from the machine, and it looks as though my machine doesn't provide any. I found a few listings for a ComfortLine heated tube. Most of them look as though it comes with a power supply that plugs into a regular wall outlet, but one looks as though it has something like a USB-C connector in the small low-res image. I'm guessing that it's a proprietary connector that attaches to the proprietary power supply, that just isn't shown in that image, but ... .

Anyway, am I correct that heated tubing normally needs to have the machine power it? Am I correct that my Resvent iBreeze doesn't, or is there a power connector somewhere that I'm not noticing? (The manual is completely unhelpful, of course.) Is ComfortLine the only kind of heated tubing that has its own power supply?

You could try a homemade hose cover (https://www.cpap.com/collections/hose-c ... s=e&_v=1.0) before investing in a Comfortline stand-alone tubing heater kit. The hose cover would be much easier to pack on a trip.

Or, you could experiment with humidification lower than your current maximum setting.

Until now, I never thought about the difference between these words. Maybe,

Condensation: Water adhering to the inside of the hose
Rainout: Accumulated condensation dripping into the mask
