I googled it uses only 390 milliamps of power. With that battery shown in your picture (7 Ah). If we assume that 7 Ah is for 10 hours average usage that's 700 milliamps per hour for 10 hours. Since this KoolerAire device only uses 390 milliamps you should get at least 20 hours of continuous usage. Hope this makes sense.
