I am sharing my personal experience about varna amber 30 littre personal air cooler. It is an awesome and good air cooler ever I purchased. I purchased it in November 2017 for the cost of Rs 8, 200/- from our local market. It’s tank has 30 littre water capacity. Motor speed is 1400 Rpm. ABS blower fan materials. Water level indicator is available. There is three speed, low, medium and full. Support and services are too good. It’s sound is not high. Power consumption heating is 190 W. They are giving true value for money. I am fully satisfied with this and strongly recommends it.
