240 pad heaters from 120v??

[Ramper]

I got some 240 volt heaters that were made for generators. 7101 battery heater (40W) and 7102 oil filter heater (50W). Since they draw such low amperage would a travel convertor (the kind you use when traveling to countries that have 240 main power) work to use these on a 120v circuit? They were made for BIG standby generators (9K - 22K), but would like to use them on much smaller equipment. Maybe our tractor.

THANKS and HAPPY THANKSGIVING

Depends on inverter rating. Take pic of its label.

Generac battery heater pads were know to cook batteries when used 24/7/365. The thermostat, wattage wasnt designed properly for continuous unattended connection. You would want to use it sparsely, IMO.
Filter heaters were not a problem as far as I have experienced.

I have not purchase a converter yet. I got a good deal on the cold-weather kit (under $25). I understand that I can't just plug it in to 120 (only 1/4 the power). They are made to plug in the the generator (only 2 wires).

If I could wire a plug and use it as an engine heater (on a timer) then I will keep it. But if there are too many hurdles, I will just sell it.

Would it be possible to wire the two wires to TWO 120 plugs and just plug BOTH in at the same time? It would not be OSHA approved, but would it work? It seems like these would need to be on different phases (circuits coming off opposite sides of the breaker panel).

These units will work on 120 but you'll have 25% of the 240 volt wattage.

The smaller one will produce 10 watts, this may very well be enough to keep the chill off a small battery. The larger one will be 12.5 watts.

The cheap travel converter I bought and tested rating were overstated about 300% from what I thought was appropriate.

When shopping look at the shipping weight and figure about 25 watts per pound.

I'd try them on 120v first
