This is the true customer feedback of our KC650 Tent Air Conditioner For Camping, it was designed with 2350BTU cooling capacity and built in the powerful Panasonic twin cylinder compressor that is 4.6CC/R ( while other compressors only 2.0CC/R). It is more powerful and efficient to reduce the outlet air temperature by 10°F in just 5 minutes. Any needs just please contact us.
