O2COOLPersonal Travel Rechargeable Battery Powered Neck Cooling Fan, 2-Pack (Pink/Gray)

Got a bundle of these for the family before our summer vacation, and MAN did it help. Some people wore them continuously 24/7 and some cycled them on& off as needed, but they all seemed to last a full day in an amusement park. Just charged them up each night next to our phones.The neck string isn't the best, but it does it's job. Maybe ours kept getting tangled because we were carrying 5 in the bag. And as others have said, it is a FAN so please don't let your hair get sucked in the vent.Also great for the makeup toolkit to help liquid lipstick or nail polish dry faster!

I like the multiple speeds and that it is rechargeable. It has good battery life before a recharge is needed. It works well and I would recommend it.

These are Wonderful Fans. So easy to recharge with USB port. Much better than heavy battery fans.

Light weight

As someone going through menopause I’d be lost without these.

I have been using these O2Cool personal fans for many years. My first was a gift from a good friend, and I've bought more for myself over the years. These newer models have three adjustable speeds and are rechargeable, which will save me a lot on battery replacement. I keep one in my purse, have them in multiple rooms at home, and in the car's glove box just incase! Would definitely recommend them and will buy them again when needed.

It gives you a nice personal breeze, with 3 levels of air flow. I use mine at work.

Helps with the heat
