NICE!!!
As a side note, since you took the time to create and post a video...
I see you are using the quick ON/OFF cycle, as just about everyone has recommended in this long thread. I always try to follow in the steps of the Trail Blazers, but recently, I’ve been purposely being less quick on the button between hits, mostly short breaks. Perhaps I’m just not giving as big a shit as I used when I first started with my IO. It’s certainly true, some battery life will be extended by turning it off ASAP, but on the other hand there is more mechanical cycles on the switch assembly, though the components seem fairly robust having seen all parts when my backend popped out on day #1, out of the box.
I also have a total of 10 new batteries, but NOT rotating, just going to us one at a time and continue to keep on charger ring. This is the only device I don’t rotate batteries and charge externally, as I never want to deal with the backend popping out. Two weeks later when I received the replacement backend, I was finally able to try my IO, for the first time.
Anyways, too many words to get to the point. In my tests, I was surprised that the DRAW SENSOR works so well, there seems like minimal heat if turned on, but not drawing. And it’s not just the user drawing air up and through the heater as convection style, the heater actually gets HOTTER when it senses the draw. I’m familiar with similar draw sensors, but on inexpensive devices it’s more an ON/OFF switch, but on the IO, the current to the heater is variable. You can test yours with a proper multimeter and temperature probe.
Point being, I’m keeping it ON between short hits, maybe I get a little bonus conduction as well. Just a thought....
