I got a Fortress, made in Hong Kong, condition is not that great but cooling is very good. 700-750 Watts, 3.5 amp, it takes 1 kw/h unit in 1 hour and 40 minutes if I keep the thermostat below 6. Since my room size is very small, I feel very comfortable at 5 during night, if I go above 6, I started feeling cold
It cost me around 12,700 rupees and bought it from G-9 Islamabad
