Wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human are disclosed. They are of the type that are clipped onto a belt or the like, and use a powered fan to dispense active. They are configured with outlet arrangements to minimize power use while still achieving acceptable air flow rates. These changes permit use of smaller power supplies and more compact arrangements for power supply (e.g., battery) positioning. This in turn permits a much more compact and lightweight construction to achieve the desired results.
