This $15 Amazon Find Is Sarah Jessica Parker's Secret to Staying Cool (and Looking Flawless) This Summer

This mini fan, for one, has all the functionality you need for an array of scenarios. Only carrying a small purse? Don't worry, it's only 5 inches tall, 3 inches wide and under an inch thick (so it's more compact than an iPhone). Need to stay cool at your desk? Great, it has a pop out stand so you don't have to prop it against anything. Hate changing batteries? Easy, this one has a rechargeable USB that charges to full battery in just three hours, per the brand. "I love this little fan. It’s portable enough to fit into a backpack or small bag and it’s not noticeable. It moves air pretty [well]. I used it in a hotel recently over night, and running [it] on low, it was able to run pretty much the whole night," says one Amazon customer.

It's also got a whopping five blades and three speeds to ensure prime airflow. According to the manufacturer, you can use the low speed for up to 14 hours straight before the battery runs out, medium speed for up to nine hours and high speed for four hours. You can also grab it in multiple colors including blue, beige or pink.

This fan may be small, but it sure is mighty—not to mention, cute. And if it's good enough to keep SJP's makeup looking flawless in steamy summer weather with the cameras rolling, it's gotta be good enough for us mere mortals. What I tell ya? She never lets me down.
