Between World Cup matches, July 4th barbecues, and beach days, summer means being outside—and it’t hot. Beating the heat indoors is easy with AC units and fans, but there’s no cooling factor when you’re facing the great outdoors. Unless of course you snag a personal fan. Right now, Amazon’s Prime Day has plenty of these personal AC units on sale. Best part? They’re all under $25.

These personal fans range from the portable to the wearable. We’ve tested a good amount of neck fans in the past though we’ve included mostly handheld options because they’re easier to stash in a work bag or daypack. These personal fans are all rechargeable so there’s no need to fuss with disposable batteries. All of the handheld options fold up in some way though the Kimguard, Playhot, and Jisulife can be folded and propped to double as a desk fan.
