12V DC plugs - what do you use them for?

[mjrendon]

What are some of uses that you have found for the 12V plugs? 

I have used it for charging AA and AAA batteries with a plug in charger and for a smaller computer (12v to 19V adaptor). 

I also have a 12V 130 WH battery pack that I can charge using 12V.

I tried a 12V electric blanket but it was underwhelming.

I use one for my APAP (CPAP) machine.  Much less of a draw than running off an inverter!

Even though I had one installed near the 110 volt outlet on the exterior during my build, I could have used the ones on the interior and simply passed the cord to the exterior.  It makes for adjusting the tires on the Ollie much easier.

We use the one on the outside, far more than the two on the inside. 

We used to use one on the inside for a small (700 watt?) Inverter for a laptop. We really only use it for usb converters now.

And yes, the outside one is mostly for an air compressor,  as topgun noted.

Any thoughts on these 12V items;

• hand vacuum
• slow cooker
• water kettle

[SeaDawg]

Imo, they're all weak on 12v. Better to get a good lithium battery vacuum,  like a Dyson, and charge when you have 110.

I have a 12vhair dryer. And a 12v blender. Neither really strong on 12v

We’ve got the Dyson, works well and holds a charge.  Our appliances are 110 but when we’re without shore power we live a more simple life, using the inverter occasionally when we need power.  I use the 12V plug for the little air compressor and to charge my TPMS monitor when the battery is low and we’re not driving.  Mike

We're planning to use these: https://www.amazon.com/Caframo-Ultimate-Cabin-Small-Black/dp/B001449QRY/?th=1

We purchased the separate clamp to use over the suction cup.

Jairon,

We ordered two and found them to be too large and too noisy.

They do have an obnoxious wine to them. Still, they should be about 60 db lower than the AC 🤪

Where is there an outside 12v outlet?

[Overland]

The early Olivers had them I think in the top lip of the lower fridge vent, facing down. Oliver stopped putting them in for some reason after their production break. They put 2 on mine because I asked, back when they’d do things like that.  We get a good amount of use out of them - mostly for lights and charging phones.  I bought a Green Mountain grill this summer which runs in 12v, so I could use the outlets for that if I take it on a trip.

I think it would be a very easy thing to add if you’re handy and not shy of drilling a hole or two in your trailer. Mine are located next to the outside 120v outlet, or right near the water pump on the inside, and are easily accessed.  But I think I like the old location better.

Overland had it right. Our first gen Ollies had one outside dc outlet here:

The little white box located under the 110 volt outlet is where I had mine placed.  As Overland says - this was back when Oliver would do special requests while in production.  And, again as Overland says - this mod would not be very difficult to do yourself.

p.s.  sorry - not the best picture but look closely just in front of the water heater.

I've used them to power my portable fridge/freezer, and other DC powered thingies.
