This thing would only work if you wanted to boost the temperature in the same direction as the a/c is providing. If it's pushing out heat and you turn this on you're going to suck more of the hot air from that duct run and push it to the room this thing is in. This is advantageous only if your house's hvac is unbalanced.
Ummm that's the whole point of these.

If you have noticeably weaker airflow / CFM from a register, inspect the duct work first. Could have came loose from the collar, could be torn, or could just be poorly ran like a lot of flex duct in attics. Be surprised how much better airflow you can get by cutting off excess and straightening some flex. I've seen some crazy loops in attics. Also pull the floor registers and look for garbage / debris. Especially with kids since they'll shove crap everywhere.

I thought this is exactly what the thermostat/thermo-sensor tries to avoid. If you set the temperature to 68, it would only kick in and start blowing when the A/C is blowing air causing the temperature below 68. Once A/C stops it continues to blow air as long as the air at the duct is lower than 68. It stops blowing once the temperature rise above 68, for this example, until the A/C starts blowing again.

Says who, the AC Infinity looks just like the other random China brand ones I bought the other day for like 20% less than that.

I have a couple of AC Infinity register boosters.

Remember, these don't just boost the airflow when your AC is on, you can set their temperature activation threshholds to keep blowing air while there is still cool air in the vent.

So long after the AC has shut off since the rest of the house is cool, you are still blowing in the cold air that would just sit idle in the ductwork.

I have 1 bedroom at the highest point of the house, aligned with the attic. By default, it's the hottest room, which becomes challenging in the summer. To keep the room cool, I need to keep the AC running, which makes the rest of the house uncomfortably cold. Would this help manage the temperature of the room? I was going to add a window AC unit this summer, but if this fan can help with my issue, I'd rather go that route since it's cheaper and quieter to run.

hmm.
so now you need outlet close to your AC register? aren't in most home the AC register is just about the furthest part from any available AC outlet?
According to the National Electrical Code, outlets should be installed so that no point along the wall is more than 6 feet from an outlet. However, older dwellings may not have had these requirements when they were built. I have one register right underneath an outlet.

I bought a cfm tester to see if the vents in my room that never got that warm were weak and surprisingly they were not, just bad windows and probably some poor insulation.
I'd like to see a slickdeal on that!

"Looks like" is the operative expression here.

Yes. That's for shortest distance of a wall to outlet, which is typical measured by straight lines. It says nothing about ceiling, or the height of wall ( you could easily have 12 ft walls, while your wall to outlet maybe 6 ft, but top of wall to your outlet could be much more than 6 ft).
As I stated, AC vents typically are as far away from outlet as it goes unless your have floor vent system

anyhow. I am somewhat curious about the difference between those products, vs, just keep the AC fan on?

My friend just bought a house that has some sort of inline booster on some of the vents and holy cow that thing blows air out those vents like nothing I have seen. I assume it's very pricey but is probably the best solution to weak vents. I bought a cfm tester to see if the vents in my room that never got that warm were weak and surprisingly they were not, just bad windows and probably some poor insulation.
All different kinds are available online and at all the big box "home" stores, here is a link to one of the cheapest I found after a brief search: https://www.homedepot.com/p/Sunco...lsrc=aw.ds

do you know of any good write up or tutorials on how to use these with hvac vents? my central air barely keeps the house warm up on 85 plus degree days and keeps the house really cold on days where the temp drops below 40 degrees.

i've had 2 hvac technicians say my unit is fine. i used an IR gun to try to gauge the temp coming out of the vent and it looks okay - so want more data to figure out what might be going on.

That's what I was thinking too, I wish they were powered by some sort of wind recharged battery but it appears that they need to be plugged in to a nearby outlet. [media-amazon.com]
Power consumption is listed as 6 watts. That's a very low number. The fans appear to be typical case fans which run at 12v. You could probably run a small battery setup with that barrel connector if you wanted. Even store the battery in the vent or behind a blank plate in the wall.

Of course the alternative is to have a professional come and flow-balance your system (or DIY if you're inclined) so you don't need band-aid fixes like this.
