will this power a 12v 300 watt cab heater?

No. It supplies a constant 8.4 amps at 13.8 volts. It will supply 115 watts which is nowhere near your 300 watt heater. Be aware that it will shut down if current draw is more than 70% of the ratings on the box so it is truly an 8.4 amp power supply, not a 12 amp. For your 300 watt heater at 12volts, you'll need to use a power supply that can supply 300/12 or 25 amps. Since Pyrimid is so creative with their claims, you would need one of their power supplies rated at a minimum of 37.5 amps to supply a constant 300 watts. In general you will find it expensive and inefficient to convert house current to 12 volts then heat with that power. You will be much better off to buy a heater that runs directly from house current. You'll get more heat, you won't lose the inefficiency of the power supply (only 60% efficient) it will be cheaper, and probably more reliable.

Its a 60W max transformer so I wouldn't think there would be a problem with 12 watts.

Yes, you can use this for anything that requires a 12 volt input, just keep in mind you want to keep the load at or less than 75% of maximum. Although mine has been operating just fine powering my led controller and 150 watts of strip lights

Power = Volts x Amps... So 300 is more than enough. Personally I bought the 500 Watt version because I use it for many things

It should work fine on any 300 watt or more power supply. It's total draw is only going to be 75 watts as that is all the power that can go through a PCI-E slot and this card does not have an extra power connection.

Usually the watts rating is on the back of the plug. If the heater rating is less than this it will work.

Yes it will, I used: Nubee® 30 Watt Waterproof LED Power Supply Driver Transformer 120 to 12 Volt Dc Output, also purchased from Amazon with no problems.

800 watts/120 volts = 6.7 amps for the heater. Current draw for the controller would be vey small.

Sure....with a 120 volt to 12 volt DC power converter. It is a digital unit, so power use (watts) should be very low. But check the actual amp draw prior to buying converter unit.

I bought mine for running a Humminbird depth finder in the house. It will power anything needing 12 DC as long as it is less than 3 amps.

I not sure. I use it for a fireplace that requires a milli votes (low voltage) to open the thermal coupling on the pilot light

I think it should! it has a guide in the manual of how to convert amps, volts and watts.

Not sure about a heater because a heater use too much power per the instructions. The brochure says it will power a laptop and/ tv depending on the time used . Buy the more amp duracell - I have the 350.

It should work. The box it came in and the unit shows it produces 12 votes, 90 watts and 7.5 amps.

No, sorry but it won't. Amps multiplied by volts gives us watts, so with the known wattage of 300 we can divide by the known voltage which is 40 (mine has even gone to 50) and that gives you less than 8.

Your heater needs 4000 Watts, however the converter is only 5000 Watts. In theory is should work however it is suggested to take about 50 % extra capacity on the transformer related to its anticipated use.Most likely it will work for a while, however the automatic fuse might activate...

Depends on the amp rating of your outlet. You will need to be able to draw more than 4000 watts from the outlet to have 4000 watts available from the heater.
