Review on 🔋 Viniper Battery Operated Fan, Small Desk Fan: 3 Speeds & Extended Working Time up to 24 Hours, 180° Rotation, Portable USB Rechargeable Fan - Small yet Powerful for Home/Office (6.2 inch, Black) by Jim Bijelic

So quiet environment noise masks that am I leave the room and forget it's on. Features are better than mfg describes in the literature IMO - says every indicator lights up when charging, but only the low setting works. All settings on my fan work when connected to a charger. I find fault with the controls - they are white on white so almost invisible. I "added" a color to the on/off/function button for ease of use (see details). The settings below can hardly be seen in the photo without side lighting. Of course, their LEDs light up, so I don't think it matters that much. Should be great for an overnight stay aboard a sailboat as we warm up. The fan that fell down and the lamellar armature have come loose, so it doesn't work. Reassembly was possible by shaking (disassembly was not necessary). It's working again, cheers :-)
