Review on 💨 Treva 3.5 Inch Portable Desk Fan with USB Port - Compact & Powerful Air Circulation with USB Compatibility by Jonathan Robertson

This fan is too weak and too loud. Also, it's not portable - you'll need an outlet wherever you want to put it. Runs on batteries but cannot charge them and the batteries run out quickly. Note that you need a whopping 4 AA batteries for this. And the worst thing is that without physical intervention it suddenly stops working. I contacted the manufacturer for warranty service, nothing was heard for a month. Then someone answered the letter and asked for the address and then disappeared - nothing was heard from them. What a fictional "company". Stay away from this brand
