Review on Mini USB Type C Fan Portable for Samsung Galaxy Note 8 Note9 A10 A9 Star A9s A8s A8+ A6s, Moto G7 G6 LG Stylo 4 Xiaomi Mi A2 Mi 8 Huawei P30 and More by Kirk Womack

I didn't realize there were four in this pack. Very good value for money. However, it doesn't work with my Mophie battery box. That's probably just because the Mophie case isn't designed to be discharged. I have a MVP5 vape mod/battery with USB-C charging and it sounds really slow. Again probably the same problem as with the phone case. I probably want it to spin a bit slower so it uses less power. In general, the purchase is satisfied.
