I just want to know if there a huge difference between 1.6 amp and 3 amp power usage.

    1.4 amperes, or almost double (or half depending on what type of person you are).

    -1 very low quality question. Mathematically, this is a subtraction question. If it's a more complicated situation than that, we don't have enough detail here to give a good answer.

1 Answer 1


The answer depends on:

  • hours used a day (lets assume 10)
  • days used a week (assume 7)
  • rate charged by your power company (assume 13 cents per kilowatt hour)

Under these assumptions, the difference is about $500 a year.

You can refer to the chart below if you want to change the hours, days, or rate.
