Zero Breeze: BUSTED! (Patreon)

It beggar believe that a company could run a million-dollar crowdfunder for a useless device, not once… but TWICE!

A useful portable battery powered air conditioner is almost an oxymoron.

Making a small compressor driven heat engine is not difficult- they are frequently used in small refrigerators. The downside of course is smaller units tend to be less efficient, and even if that wasn’t the case, running a heat engine like an air conditioner is a power-whore. Put simply, a battery big enough to run an air conditioner for a sensible amount of time, would mean that it wouldn’t be portable.  Alternatively, if the power consumption is low enough that it could run for a sensible amount of time on a battery, it would cease to be effective as an air conditioner.

This is the bizarre joke of the ‘version 2 device’, -they claim its twice as powerful as the first generation. That’s just another way of saying it drains the battery twice as quickly. Further, even in the best-case scenario, this version 2 device (a bargain at $1599) has 1/3rd the cooling capacity of a $200 window air conditioner!
