spinning Thoughts for the mind's impeller, as my latest ffb1212ehe is en route.
I was able to spend 2 nights away, and brought my own 22Ah 12v AGM UB12220 battery and my 92mm delta 175cfm clamp fan, more for the white noise when trying to sleep ( tinnitus) than body temperature control, but I am very used to a directed stream of air blowing over my bed at a minimum, as well.
I didn't bring an inline wattmeter to check battery consumption, but after 2 nights at 8 or so hours of fan runtime each, the battery read 12.77v when I plugged it in to charge. It normally rests at above 13v for a week, after being fully charged.
I should have seen how many AH it took to return it to full, but .....
Carrying a 14Lb battery 22 Ah 12v AGM battery was way overkill, but I slept well enough in a foreign room/bed.
In another thread I posted how I Committed to the Ridgid 18v battery cordless tool system, vs Dewalt or Makita or Milwaukee. Mostly as Ridgid will replace failed registered batteries, and their batteries can be obtained occassionally, for significantly cheaper than the other brands.
I got the brushed drill/driver with charger and 2 2.0Ah battery kit at first,
then the 4.5 inch angle grinder with 2 4.0Ah batteries and charger kit.

I ran across this adapter for the batteries.

I imagine a 92mm delta fan attached to this adapter plate with a xl4015 based 5 amp Vbucker speed controller, one with a current limiter, which I can use to prevent 20+ Ridgid battery volts reaching the fan's circuit board.
I can use the current limiting potentiometer to limit the max speed, so even if I crank the potentiometer all the way up, it will not deliver the ridgid battery's 17.2v to nearly 21v range to the circuit board of the fan, potentially frying it.
I've fed 15v to 12v Delta fans without issue, but there's little to no point in going above 12.0v as they are so powerful that I rarely feed them that electrical pressure anyway.
Basically the 92mm 175cfm fan at high rpm, is so loud, it is unusable for any significant duration. I only tend to crank it to max after showering and helping to dry completely, that which the towel did not. It's on 24/7, but at near its slowest speed where it can barely be heard usually in the 0.8 to 0.15 amp / 4.2 to 5.5v range, IIRC.
There have been times when Fiona wants to go for a walk, badly, near noon.
The hotter days I'll wet her down before we head out, and she acts like a sled dog until she's nearly dry, then we bounce from shady spot to shady spot on the return. I carry water to wet her back down and allow her to drink, but the days without a breeze are tough and she will not stand up until ready.
The Ridgid battery powered Delta fan, will fit in my cargo short's side pocket. Crank it to 15v, Aim at dampened fur.
Fans everywhere.
