Putting A 12v Socket Above 220w Power Point

[30CRUZ Lurker Find all posts View Profile Close 30CRUZ]

I like the idea of having both 240 (220) and 12v in the boot of the GXL

I found this on ebay and wanted to see what others thought?
and would it be possible to install it on one of the removable panels on the LHS in the boot?

or my alternative is to just put a single 12v socket above the existing 220v point (as there is room to do so)

Thanks guys. :-)

I can't comment on the panel you linked above, however I put a plain 12v socket on the opposite side to the 240v socket.. Plenty of room behind panel & I tapped it into a big 12v cable I have going to an Anderson plug .. I use it for my engel fridge when traveling.

I have a 12v socket above and below the 220v socket. Not much room because of the rear ac but enought to fit a 20A plug above and below.

I have a double 12V socket above the 220V socket. It was pretty easy to do. The wiring for the 12V that is in some models instead of the inverter is behind the panel with the socket.

Took me about 15 minutes to do. The most difficult bit was refitting the panel as I have put an on/off switch in. I will post a pic later.

Thanks for the replies. Any photos would be a great help

Just bear in mind that the existing wiring is quite small and the capacity if I remember correctly is combined across all the 12V outlets. I would run a new cable back to the battery (main or auxiliary) if you are planning on tapping 10A total on that circuit or thereabouts.

As promised here are a couple of photos of how I did the extra sockets.

Is that switch above the inverter power point for the 12v sockets or did you tap into the inverter and install a switch ??

When I installed my sockets I ran 8b&s cable from the auxiliary battery down the drivers side, past the rear air con and split it with two 20A fuses to the two 20A plugs. The 220v plug is next to useless. The wires are hair thin and it can only handle 0.5A which isn't enough to charge a phone.

You can swap it for a 12v plug from Toyota but it's $120 and again next to useless.

I have not looked at the wires behind 220V outlet from the inveter to the outlet so i cannot really comment on the size.
But 0.5 amps at 220 volts would be about all you need.

The outlet is rated at 100 Watts at 220 Volts.
The formula to work out the amps (current) at maximum load of the inverter 100W
P = Power in Watts
E = Volts
I = Amps

I = P divided by E
so we get 100W divided by 220V = 0.45 amps

Now we know the outlet can supply 0.45 amps at 220 Volts

Then you plug in a 240/220 volt to 12volt power supply into the outlet.
How many amps can you get at 12 volts?

I know how many amps my fridge needs when it is running.
Mine runs at 3.9 amps

Formula
P = E X I
12V times 3.9 = 46.8 watts.

This is half of the maximum power the inbuilt inverter can provide.
I have not included any power loss in the power supply or the inverter but if we go worst case 85% efficent the power from the inverter will be 55 watts.
Next
How may amps is the inverter taking from the car?
Worst case 55 Watts.
Using the first formula

I = 55 divided by 12
About 4.6 amps at 12 volts going to the inverter from the cars wiring.

All i am trying to point out is the inverter can do more that charge a phone or laptop.
I have run my fridge using the 220 to 12 volt power supply plugged into the inverter outlet for hours while driving.
I have read other comments regarding the inverter and what it can do.
Maybe the new 150 has a different inverter.

That said, I would still recommend auxiliary battery and run a suitable size cable to a 12V outlet to keep the Fridge running when you stop for an extended time.
Use quality Anderson plugs for any plug in application and you can't go wrong

Yes it is for the 12V sockets. The most difficult and time consuming part of the whole process was rearranging the wiring to refit that panel because of the switch.
