Math is wrong... it should be 1500/60 minutes or 25 watts per minute... not 1500 watts per minute... appliances are rated per hour usage... so for one hour of the induction stove use it will use 1500 watts... problem is it's not running 1 hour... but 5-10 minutes at the most... so 5*25 = 125 watts power used... 10 minutes is 250 watts, etc... pretty simple... there are numerous power/wattage calculators that will tell you based on how much power the appliance is using... your figure would mean a 1500 watt heater in the cabin is also using 121 amps too... how can that be George? Shore power is only 30 amps!

You must be asking how much amps is it using... 1500 watts/ 110 volts = 13.6 amps per hour... so based on that 5 minutes usage is: 1.136 amps... 10 minutes of usage is: 2.272 amps.

That is the total power being drawn from the battery +/-.

Clear now?
