Review on 🔌 VIVOSUN USB Powered Clip Fan with Hanging Hook: 4 Speeds, 2 Level Light - Perfect for Camping, Baby Strollers, Gyms, Home Offices by Elizabeth Sautner

If you plan to use these in your tent please note that they are USB charged and battery operated. Another reviewer said it turns off every 30 minutes. I didn't know or realize this BUT they are definitely NOT timer compatible because they stay on after the timer has turned them off AND WORST, they don't turn back on. Depending on what you are using them for, this could be a oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo fire hazard. For a company that sells all kinds of grow lights, tents and other indoor growing items. I can't believe they are selling this product designed to be attached to the poles of their own grow tents even though they know all these facts. If I had known they worked like this, I would not have bought them. Apart from what I said above, they are good strong fans. but, as Biden would say, "C'mon dude!" Vivosun should work better!
