Amps used by common RV items
I'll start a list here of the amps used by common RV items. Some of this came from Wilton's site and I've change the amps after looking at owner manuals.


Lighting (1156 Single bulb)___________1.3
Lighting (Led 1156 Replacement)______0.1
Lighting (Fluorescent)_______________1.4
Fantastic Fan Low__________________1.86
Fantastic Fan Medium_______________2.29
Fantastic Fan High__________________3
Stove Hood Fan____________________2.2
Microwave on inverter_______________90
CO Detector_______________________0.06
LP Detector________________________0.086
Water Pump_______________________3.8
Water Heater______________________0.75

Please add to and/or correct this list as needed.

Special note re: newer Roadtreks with Tripp Lite inverter

If you have the factory installed Tripp Lite inverter and if it was left with the switch on "Auto" you would use 30 amps in 24 hours!

Inverter 24 hrs @ 1.25 = 30 amps

On the Tripp Lite inverter there is a 3 position switch. The choices are: Charge only, Off or Auto (inverter on + charging if plugged in). Remember to set it to Charge only when you are not using the inverter.

If you have a remote switch you have 2 choices: Charge only or Auto (inverter on + charging if plugged in). You can buy a remote switch to make it easier to switch from Auto to Charge only. Here's a link to making your own switch:

I never knew a single 1156 bulb used that much power. Never saw any specs on them

I just googled 1156 lamp amps and the first two sites I checked show 2.1 amps for a 1156 bulb!
