I absolutely love my little portable fan. Don't let the size fool ya. It puts out some serious air flow, I know because my a.c. broke an it was 98°in my house & I was miserable. Put this bad boy on coffee table in front of me and I was impressed by the amount of air flow I could feel. I was able to sleep thru the night, well until it cut off. I believe it has a built in timer or something because it does turn itself off after along time using.
We also took it to the Beach for the baby. Put it in her Dome aka portable round playpen lol and she slept through out the day and never once was hot or sweaty.
If your looking for a portable fan I absolutely recommend trying this one. It's small & compact already, but it also folds down even smaller. It's been a lifesaver for me.
I have pics to post to show, however there's not an option to upload pics.
