12v through receptacles?

Hi everyone I知 new to the forum and I have a question. I just bought a 2008 Jayflight 22FB and I知 wondering if when I知 not hooked up to a power source, will the battery produce 12v through the receptacles? I ask because I知 interested in purchasing a 12v to 120ac converter, and then plugging in a small inverter to be able to charge a cell phone or run a fan etc. Thanks in advance!

The battery will not send 12v to the outlets. It powers the lights, fridge , heater, etc. If you want 120 volt from the outlets, you'll need to install an inverter connected directly to the battery, to provide 120 volts. Or, install a 12 volt cigarette recepticle connected to the battery to power your cell phone charger.

I installed an inverter after doubling my batteries from one to two when I anticipated an occasional overnight without any shore power. Trust me, there's some math involved and don't take that lightly. You need to calculate the draw in watts or amps you anticipate and size the wire from the batteries to the inverter correctly. In my case, this also required a three hundred amp breaker since, as I discovered, DC amps are very high when converted. It's been awhile, but if I recall, the wire gauge from the batteries to the inverter was #2. Good luck with your project, but take your time to do it right. Just as in house wiring, a mistake can melt insulation, or worse, start a fire.

In addition, there are fixtures that feed twelve volts to lighter type receptacles, and usb ports, in banks of two. I also put two of those in side by side and they are wired directly to the 12 volt line inside the trailer. It provides all the charging connections we need for several devices at once when on shore power.

Your house battery is 12 volts. Unless yours is different than mine and the three RVs I owned before this one, the interior lights run off of the house batteries. In the toy hauler I had only one light that was 120V and that was the dinette. Why, I have no idea but it was.

That's what I said above. Here, I'll post it again:

If all you want to do is charge USB devices or run a small fan, don't even think about going the inverter way by converting 12 volts to 120 volts. For what you need this method is extremely hard on batteries and inefficient. An inverter should only be used for short periods unless you have solar or plan to keep recharging the battery.

To charge your phone you would be changing 12 volts to 120 volts and then back down to 5 volts. There are much better options out there.

I use a USB charging hub that plugs into a cigarette lighter outlet and provides multiple high power charging USB outputs. This will charge multiple devices at the same time fairly quickly. As long as you get a high power version you are good to go. I plug mine into the front outlet in my class C through a long extension cable so it uses the chassis battery.

As far as a fan is concerned, if all you need is a small one you can get a USB type and plug it in here. If you need to move some air you can get a 12 volt fan that should fit the bill.

In any event you should get a voltage monitor to keep tabs on your battery. If it gets too low it will be damaged and lose capacity.
