Sticks to the phone greatly. Cooling is very strong. I strongly recommend it to anyone who uses their phone to play games.

Just exactly what I wanted. I wasn't quite too sure about how it was going to charge but this has been exactly what I needed for playing Pokemon Go outside here in Texas in the middle of this hot summer. Before having this for my phone, I would get the overheating warnings within about 30 minutes of going outside. That isn't exactly beneficial when we have events that last 3+ hours. I bought the fan about a month or two before Go Fest because those are going to be some long hot days. I've had the chance now to use the fan twice for events just to see how well it holds up and I have not been disappointed. It magnetically attached to the back of the phone. With the USB-C port on it, I have my spare battery battery pack hooked up to it and my phone at the same time to ensure plenty of time to play outside in the sun without fear of my phone shutting down. I can't recommend this fan enough if you are a fellow gamer or just Pokemon Go freak like myself.

Now i can play games without heating issues and lag problems. This fan is really handy and light weight. I can carry it anywhere and use it with any power bank. The price is genuine but i can pay more for this type of product.
