A San Francisco-based startup has launched a Kickstarter campaign for a portable air conditioner that packs more than just a rotary compressor. The Zero Breeze is designed to illuminate, play music over Bluetooth, power devices, and last up to five hours on its rechargeable battery.

Portable air conditioners are widely available in sizes ranging between that of a toaster oven to an upright garbage can. While most any of these can effectively chill interior spaces to a point, the need for a continual power source limits outdoor options. The team behind Zero Breeze has managed to cut the cable requirement without significantly sacrificing the cooling power.

Zero Breeze uses rotary compression refrigeration technology along with an "environmentally- and ozone-friendly" Dupont R-134a refrigerant. Since the system is closed, users won't need to worry about adding refrigerant over time. Zero Breeze's cooling output is listed at 1,000 BTU per hour and designed to handle areas up to 50 sq ft (4.6 sq m). In closed quarters, it could reportedly be possible to bring the ambient temperate down to 44.6 F (7 C).
