Whether they're dispersing fumes from floor poly or simply cooling things off when it's hot, fans are an essential piece of job-site equipment. Ryobi's new cordless unit is an alternative to the battered box fan you've been hauling around for the past decade. The P3310 is powered by an 18-volt li-ion battery and can run for up to 10 hours at the lowest speed, the maker says. Since it's cordless, it doesn't compete for scarce electrical receptacles, and it can be easily moved from room to room. As part of the ONE+ 18V system, it's compatible with all 18-volt Ryobi batteries.
