This fan is freakin' amazing! I've bought one for myself and two as gifts for others. The amount of wind power that this little thing manages to produce is a wonder. It's comparable to a traditional desk fan, not a portable fan--and better even than many of those!
It folds up small enough to take with you when traveling. (Assuming you're checking luggage and portable cooling is important to you. I mean, it's not pocket sized.) I love that you can adjust the height and angle, so I can have it tilted towards me when I'm applying makeup in a muggy climate.
I was pleasantly surprised how long the battery lasted and how quick it was to charge. (Though I do wish there was some indicator of battery life.) I didn't expect it to last long for the amount of oomph it has, but I had no problems. Also, you can run it while plugged in if you're gonna need it for awhile.
As others have said, there's a cable but no wall adapter included. It uses a USB-A to micro-USB connector, so most likely any charger you have on hand with a standard USB port will work.
The only down side is that it doesn't really function as a floor lamp as advertised, at least where I tried it on carpet. It immediatly tipped over.
Seriously though, I love this fan.
