Monday, February 9th, we awoke to minus 20F temps....not conducive to enjoying the outdoors, so I decided to lite a fire in the barn and work on the Serenity Falcon.

It has been one of the coldest winters in years, we have mostly enjoyed the weather and snow...but this is a bit much.
Since we upgraded the batteries in the Serenity, we find that we don't plug in much and most of the time are operating on 12V DC power. We have also started bringing with us a 12V compressor refrigerator (cooler) and installed a Starlink Mini in our skylight that can operate from a 12V source. However, the Serenity has only two 12V outlets, in less than convenient locations. To remedy this I installed three, multi-port 12V/USB outlets.
1) Outside compartment near the RV entry. This is to power our 12V cooler when we move it outside and what ever else USB device we need to power. It has 3 12V outlets. 1 C port, and 3 USB ports. It is also switchable and has a voltmeter. Everything is switched such that when off it does not use any power.

Eugizmo, 12V, 200W outlet.

| Under the seat behind the passenger |
I powered this and the second outlet from the same power source as my leveler jacks, which is protected by a breaker and the socket is also fused.
2) Behind the passenger seat. I used the same power source but installed it in the seat support behind the passenger seat. This unit also has a meter and when switched off draws no power.

It is always a bit intimidating to drill holes in fine cabinetry.

| 12V socket and 2 USB ports |
This is a simpler unit of a single 12V socket and two USB ports. It has a 20A rating (240W).
3) In the corner under the rear bed. I put this one here specifically because this is where the 12V cooler lives when it is inside the RV. The electric bed goes over the cooler at night but it is accessible during the day. I used the same outlet I put behind the passenger seat but for some reason the meter doesn't work, but I really don't care as long as I can switch if off.

| Under the electric bed |
I pulled power from a previous USB install I did years ago to power our phones at night. The socket I stole from is in the rear storage compartment under the bed. Honestly, I don't recall where it got power, but I know it is fused, because I did it.
These installs will allow us to run devices that are 12V without running our inverters, thus allowing our batteries to last a bit longer.
We have a large 3000W inverter that runs the house 120V system and a small more efficient 400W inverter in the media cabinet, that I installed when we bought the Serenity, that power the TV and a few USB devices (Like the Firestick, Roku and Chrome dongle).
We are working towards a early March departure south this year, so I am happy to get these off my list before we launch.
