It plugs into a standard outlet - just be aware what else is on the same circuit. DW has a habit of forgetting and puts the coffee machine, or her Ninja cooker on at the same time and it flips the circuit breaker. I make her go and reset it now and she's getting the idea ;)
The unit I purchased uses the condensate to cool the evaporator and then ejects it as vapor out the exhaust so haven't noticed any issues so far. It has an auto switch if the storage tank fills up and then there is a drain plug - just not needed it so far.
