Why this gift works

The Treva 5 Inch Clip Fan from O2COOL is a two-speed personal fan with a heavy-duty, rubber-gripped clip that fits surfaces up to 1.5 inches thick. The head rotates and pivots, and it runs on USB power or 4 AA batteries - 14 hours on low or 11 on high, per Treva. This is the Gray color, model FC05009.

Plenty of older dorms have no air conditioning, and a lofted bed sits right up in the warm air. A fan that clips to the bed rail puts the breeze where it matters.

Who is this gift for?

Great for

  • A top bunk or lofted bed
  • Hot move-in weeks
  • A desk corner

Think twice if

  • The room has good AC
  • The bed frame is thicker than 1.5 in

The catch

A 5-inch fan cools one person up close, not a hot room; batteries are not included; and the clip opens only to 1.5 inches, so it may not fit thick bed frames.

Skip if their room has good air conditioning.

What to look for in a dorm fan

  • Mounting. A clip works on bed rails, desks and shelves.
  • Power. USB plus batteries keeps it running away from outlets.
  • Size. Small fans cool a person, not a room.
