A camping adventure is more enjoyable when you sleep well. And during the summer, sleeping in a hot, humid tent can be a challenge. This portable air conditioner from Zero Breeze ensures your sleeping area is cool quickly using a new dual hose system that is twice as strong and more efficient than the first-generation model. Ideal for tents, trucks, and RVs, the new MK II has shrunk the size of the compressor down to a soda can so it's easy to pack and transport before your trip. And once you're ready to set the Zero Breeze up, it can reduce the temperature in your space by 20°F in just five minutes. It all runs on a high energy density battery that not only provides five hours of coolness but also doubles as a charging station for USB and USB-C compatible devices.
