title_body: Low wattage K-cup type office machine
upvoted_answer: Well, I don't know anaything about keurig, but as the Question stands for a Week I give it a try.
  
  From my expierience with electronics, there are 3 ways how a low power mod could be done, depending on the details.
  
  the first is to mod the power supply to the boiler (e.g. put an inductor in searies) and hope the machines software can cope with this.
  
  second: If you do have to modify the software(and are able to, Replacing the controller  and reimplement the software may be required) you could implement a pwm regulation of the heating(your power line got to survive short overloads of ~0.1s)
  
  third: The boiler has a to small heat capacity for a full cup and needs to draw full power during the pouring of coffe (my machine does this when it has to make a large cup). You have to change the boiler (bigger one might be to big for the case,) and then continue with one of the steps.
  
  Note: If this can't be done in the fashion of “the nerd in the next cubicle does it for free coffe and no one ever is to talk about the mod” but you have to employ an external firm and need to match safety regulations you are almost definately cheaper off by upgrading the power supply to the office.
