With the Hurricane O2 Canless Air System, we finally have a viable alternative to canned air. Each charge of the H2’s batteries gives you the equivalent of 25 cans of canned air, but without the chemicals, greenhouses gases, and risk of explosions. Shoot a blast of air at over 200 mph at any angle and maintain it for 12 minutes! We love our Hurricane 2 Canless Air System for the usual techie stuff, but it’s also great around the house, in our maker’s workshop, and even as a firestarter when we want to roast marshmallows.
