What Are Those 12-volt Sockets Good For?

We have all done it.  Left the cell phone charger sitting on the kitchen table closed the front door, made sure everything was locked up and left for our weekend RVing get away.  If you have one of those not very smartphones you know that in 8hrs or less the phone will be dead and your Hot Spot, Weather App, and every game that keeps the kids quiet during the ride will come to an end.






What to do?  Have you ever wondered what the 12 Volt Standard Wall Plate that looks like this is used for?

Or maybe you will remember this 12 volt Wall Plate with Antenna Amplifier & Switch it looks like this;

Both of these wall plates have a 12-volt power socket just like your car, truck, or RV does.  You could plug a car charger for your phone or tablet computer into the wall plate and it would start to charge your phone or tablet computer.  Ah, but you say you have a charger for your phone already why would you need another one for the Rig?  If you remember you left it on the kitchen table and left for this trip.  OK, now what?  Well if you bought one of these 12 Volt Single Outlet USB Charger which looks like this;

Then all you would need is either the Apple Charging Cable which looks like this;

or the Android charging cable which looks like this;

and you could charge your phone, table, or any USB device and never have to worry.   You say that you need to charge two USB powered devices at the same time.  Don't worry be happy and buy a Dual USB Charger which looks like this;

Now all you have to do is plug in the appropriate charging cable and you are good to go.  If you need longer charging cables than 6ft you can get them up to 10ft for both Apple products and Android products.  If you would like to be able to plug the charging cable into a normal wall outlet you can buy those also.  And for those of us that want it all you can buy the USB Charging Kit Bundle  The one shown below is for Android but they have them for Apple as well.

But they have the Apple Charging Kit Bundle as well, which is shown below;

Well, that should get you going and you can just plan on leaving any of the items we talked about in the Rig for the next time you leave the charging cable and power supply on the kitchen table.


PLEASE NOTE:  The following comments may not apply to all RVs.  Without checking the wire gauge behind the socket plate there is no way to be sure that the following products can be hooked up to the 12-volt socket in your RV.

Along with the ideas above, you can use the power plug to power small appliances such as a coffee maker

or maybe a 12-volt frying pan.

Maybe you are boondocking and would like to use your PS3, or some other video game or even some device that only runs on AC.  Then you would use a DC to AC converter.

This would allow you to power Dual USB ports that can charge most phones and tablets simultaneously (Max 4.8A total output), while two grounded AC outlets (300-350W) great for charging a laptop, breast pump, nebulizer, game console, kindle, TV, DVD players, lights, iPad, and other electronic devices.

The idea here is that if the park AC power fails you can use the 12 battery that powers your rigs lights, to make coffee while you wait for the power to be restored.  While you are refueling next time at a truck stop go inside a look at all the 12-volt appliance available to the trucking community that you can use in your RV or towing vehicle. [NOTE, not all 12-volt wiring can handle 12-volt appliances.]

CAUTION:  This is not a long-term solution for power outages as your rig's battery will run down very quickly if you make dinner this way with no way to recharge your RV onboard battery now that the AC power is out.











Until next time.
