Review on 🌬️ Stay Cool Anywhere with Mini Cell Phone Fan (6-Pack) - Colorful and Powerful 2-in-1 Fan for iPhone/iPad/Android Smartphone/Tablet - Must-Have Cell Phone Summer Accessories! by Christopher Lance

I ordered two sets of these for a bachelorette party hangover bag. While some of them didn't work right out of the box, Revain was quick to send replacements. I tested all of the fans on my iPhone 8s and here's my experience of the issues other reviewers had: Fans turn off. after a few seconds when the phone is locked or free. With the phone unlocked and in use, I ran the fans for about 2 minutes at a time with no issues. Sometimes I found that some fans would turn off after a few seconds even with the home screen unlocked. I thought it was the case on my phone. As I plugged in the fans and observed the connection, I saw the connector being pushed out due to the pressure of my case against the plastic housing of the fan tray. I removed my case and tried again and found they work fine. Still, for the price and for our purposes, they were worth buying.
