Like this one?USB fans. There are a lot of uses for these small lightweight fans both for camping and in the home. I currently own 5 of them with 3 being in the Casa. One is used for forced air behind the Iwatani stove and heats the interior in just minutes. If you use a Buddy heater they can also be clamped on the back to push heat out instead of having it go straight up.
But the one I want to talk about takes the USB fan to the next level. It is called the Frizcol and has some significant differences from the standard little black fans. First of all it is blue instead of the ubiquitous black, not a big deal but I have seen enough black plastic crap to last a lifetime. More importantly it is very quiet, moves a lot of air and has a long lasting 12,000ma battery that just keeps going. It has the standard USB input and also a USB C output and enough battery capacity to charge some other devices.I used it all winter to charge a Bluetooth speaker. It also has a two level LED light that can be pretty handy. It comes with the usual 3 speeds but also has a built in timer that can be set for 1, 2 or 3 hours.
The plastic molding looks to be first class, everything is tight and firm, the clamp is extra strong and is notched to accommodate a number of surfaces. In addition to the clamp it also has a folding hook so it can be hung in a tent, etc. And finally it comes with a remote that seems to work from several feet away. The remote was the cause of some bad reviews, not because it didn't work, but because it was cleverly stored in the clamping base and most people never found it!
The big battery and clever design move the Frizcol to the front of the class for now, a definite improvement over the other 4 that I have. My one gripe is that the controls on the back are recessed and hard to tell apart in the dark. To correct this oversight I used Loon KnotSense to build an upsticker that could quickly be identified as the off/on switch and now it is essentially perfect.
I also have a 10'' O2Cool fan in the Casa that came as either battery powered with D cells or a 110v power cord. The D cells were a brain fart and I modified the fan to use any 12v power supply instead, much better. It has been running in the Casa as a test for a few days during the heat wave while plugged into the Jackery 110 outlet. It uses <1% of the battery per hour so would run for days on a single charge if necessary. It was 93 degrees in there today but with all 3 fans running it dropped to 91 and was comfortable enough for habitation, not pleasant but manageable.
