Is the difference between this one and the $9 one from the other day4,000mah vs 2,000mah? so the one in this OP should last twice as long? The fans look the same and its hard to tell what the difference are.

Not sure what the difference is… I ordered the $9 one from before. It says 4,000 mah too and also says lasts up to 12 hours.
I was thinking about returning the one I bought because like everyone else says it is very loud to use indoors but air flow is good and will probably be very useful during the hot summer heat.

Bought this last time. Seems good. Use it for outdoor swim meets in Texas. It's not that loud for outdoors while kids are screaming. It moves a good amount of air and last 4ish hours enough to get through a meet.

Received it yesterday - it works very well! My wife would like to have a stroller holder for it though. Maybe I can justify buying a 3D Printer now.

I was going to get that trash but then saw this one. Seems like a much better bargain with more features for only $10.49. Claims to have a 5000 mAh battery and 100 speeds. But the real kicker is a Peltier cooling disk that makes it blow cool air. You can also rub the disk on yourself for instant relief. Watch this video of water instantly condensing on the disk.

Consider this $10.49 model instead. Claims to have a 5000 mAh battery and 100 speeds. But the real kicker is a Peltier cooling disk that makes it blow cool air.

I just ordered that Peltier fan because I need to see how it's set up. It shouldn't work - Peltier coolers move heat from one side to the other, and inefficiently at that. So there should be net positive heat nearby. All cooling systems do that, move heat somewhere else. Eg a window AC unit moves the heat from the room to the outdoors.

But that cooler looks like the cold side faces the user, and the hot side is... where?

My thoughts exactly, I was confused because anywhere the heat could dissipate would also affect the air it blows on you, unless its going to the battery/grip which is just as bad.

the "superconducting ice magnetic cooling" in the description did give me a chuckle.

Got this last week. This is loud AF. Also, battery lasts only couple hours at like 50% power.
