It is 750W, Heavy duty mixer grinder, certainly the most powerful I have experienced till date.
It is sturdy, has a compact footprint and it is very powerful - it can make coconut chutney within 30 sec, that too without grating the coconut first. Simply awesome, go for it...
I also found a small video showcasing the power of this machine - Grinding Bricks in Philips HL7699.
