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

This little fan saved my son when he was on a humanitarian trip to Mexico. He laid concrete and roof for an elementary school in Ixtapa (10-hour day, mid-August). He brought it and everyone on the site passed it out all day for relief! It's tiny and with constant use like my son and friends used it, the batteries had to be changed every other day. But with the plug-in option, he could also sleep all night with the power on to get some relief in his air-conditioned hotel room! It's a great, compact and versatile option (aka battery and mains powered) for the right circumstances.
