All the credit for “significant modern invention” goes to fire, the wheel and modern automobiles, but we’re particularly fond of the advent of environmental controls and, specifically, air conditioning. It’s now available in homes, offices, cars, shops and everywhere else you spend a significant amount of time, so why shouldn’t it be available on-the-go, in tents and other portable structures? It should. The Zero Breeze Mark II Battery Powered Portable Air Conditioner makes it possible. In essence, it’s a portable cooler sized air conditioner with a 200% boost in power over the previous iteration that can drop outside temperatures by up to 30 degrees Fahrenheit within ten minutes while still being 40% more efficient, having dedicated sleep and dehumidifier modes and also charging your gadgets in the process. The Zero Breeze Mark II is basically a breadbox-sized device that will keep you calm, cool and collected regardless of what nature decides to throw your way.
