Once you are a sleep on a boat or closet LOL you might not need it for the rest of the night. The Q marks were supposed to be shocking faces that did not come through on the post LOL
By looking at the battery they could make a bigger one that would last 8 hours.
Anyway, they are in the right direction Better days are coming
As I said before it is not for me and here are the reasons.
Cost of $399 for cooling capacity of
only 1100 Btu/Hr is insufficient for me.
Even though I like the battery pack, only 5 hours of operation without recharge would not work for me.
Not available for shipment and still looking for backers.
All of this could be improved in the future but I am not talking about the future.
This unit might work well for others but I am not talking about others and am only posting why it would not work for me. OK
