x Quantity

x Hrs. run/day

=Total amps/day

10 watt lights 0.8
15 watt lights 1
Water pump 4
12 volt TV 3
Automatic Fan 2
Furnace 8
12 Volt Stereo 0.8
Propane Alarm (usually 24hrs/ day) 0.21 1 24 5

Vacuum (average 0.15 day) 35
Curling Iron (average 0.15 day) 3
Blow Dryer (average 0.15 day) 125
Total amp hours per day

Step 2
– Calculate your total weekly amps

Multiply total amps hours per day by the number of days per week (i.e. weekend camping: multiply
total amp hours x 2 days, full-time camping: multiply total amps per day x 7 days).
_____________ amps per x ______________# of days of use per week = ________________ total amps
