It is true that summer is hot. But here is something to make your day easier. Are you prepared? Meet the new AirFreez— an alternative to traditional Air Conditioners that cools you just the same!
How does it work?
It is surprisingly easy to set up! You just need to plug it into a socket（插座）OR any USB port （it uses so little energy that it can even run off of a phone or laptop battery）.
Once you have done that, simply fill it with 20oz/0. 6L of cold tap water.
Now just press the power button and the instant cool air is here!
What is so special about this little box?
It is no larger than a lunchbox. It can be powered by a pocket solar panel（电池板）or battery pack and you probably have the world's first and most portable AC unit.
Bad sleepers are putting the AirFreez next to their beds at night. The relaxing blow of cool, clean air, the comforting soft night light and the quiet create the perfect sleeping conditions!
The price is just amazing. Most AC units cost at least $ 300+ AND you have to pay more to cover the expensive electricity bills each month. AirFreez costs less than $ 100 （actually $ 53 if you buy more than one here）.
Top Tips：
●To make your air even cooler—add a bottle of cold tap water from your refrigerator or even ice!
●For a beautiful relaxing atmosphere—add a few drops of fragrant oils to the water!
