Topic: Small Generator Posted: 30 Jun 2016 at 11:38pm |
Most coffee makers draw 1,000-1,500 watts, so you would need a large inverter to power it (the generator doesn't have a chance), and even then three pots of coffee would drain a single marine battery.

Thanks.
On the back of the inverter it states;
Input: 13.2V DC, 45.5 A max Output: 115 V AC, 60 Hz USB Output 5V, 2.1 A 600W/4.2A continuous Neutral Floating
It does state on a warning label on the 12V male end, not to use with electrical Appliance that draws more than 100 W, as the current could blow the internal fuse in the inverter.
Odd that it is rated for 600 W with this statement however. Other than cell phones, iPads and the CPap unit I don't plan on using it for any other appliances.
Saying that I wonder how much the Jensen TV draws power wise? I have a 2015 RPod 177

If the "male end" is a cigarette lighter type plug, that is why. I have not encountered many of this type that I would want to pull a lot of amperage through. 100 watts at 120vac would be about 1 amp. This would require (roughly) 10 amps at 12vdc into the inverter.
I can't speak regarding your Jensen TV. I have an older Emerson 19" LCD TV and it uses 55 watts.

There should be some other terminals to be used for higher power. BTW, even though the label says 45.5A at 13.2, the current will increase as the input voltage drops. A 12V battery, not being charged, will read 12.0-12.7 volts and the 600W input current will go above 50A. There should be a label on the Jensen, but it should be 100W or less.

Let's go back to the CPAP machine since that's your primary need. Look at the AC adapter it has and see what the output of it is. On ours it was 12v DC. It only required a straight plug into a DC outlet which I installed in our "entertainment center" over the bed. Many of these medical devices run natively on some form of DC so they can have battery backup. Before you convert DC to AC and back to DC, check the power requirements.

For your DC plug, did you draw the 12 V power from the entertainment power? Did you also use the asme ground as well?

There's a 12v circuit that powers the lights and antenna amplifier. I used that circuit. It seems adequate, although our CPAP doesn't use a heater. I don't understand the question about the ground however.
