My nittoo 1300w already 3 years old, everymonth 15mi warm up.

Longest running time was 2 days with only refuel stop every 5-6 hours.

Ran a .5hp aircon with this during the night bwounts. With ac, runtime was just approx 4-5hrs.

Ok naman, kaso mejo maingay kaya ginawan ko na lang sealed enclosure.
