12V Outlet - Allways Live?
Posted 15 July 2012 - 08:12 PM
I wonder if anyone know if it is possible to get the 12V outlet allways live? I have a Waeco (energy friendly compressor version) coolbox which would be nice to use even when the car is parked..
Thanks in advance!

(nothing fancy, just cheap ones so no built in battery protection on them to save excessive battery drain)
i would not run either for any length of time on a parked iQ with a standard battery even tho the aH is not that high..
I plug the fridge into the vehicle when traveling,
(or a split relay & a second leisure battery) if running a car with one fitted,
If no battery being carried I used a 'smallish' Rechargable Power pack which i charged at home first or while driving, then plugged the Fridge/coolbox into that while parked,
that way, no chance of flat batteries.
My Small Fridge/hot box is.
On, DC 12v on COOL, 50W, 3.8A
HOT, 40W, 3.2A

I suppose Toyota making theirs plug in the AUX socket naturally protects the battery as its a switched live although not an engine run live,which lends itself to people putting the first stage of ignition on and flattening it. Most small "beer" fridges nowadays run on Peltier chips which are generally low current and presumably used in car applications.I don't think a compressor type fridge is suitable for the iQ. what is the current consumption? may show in watts on a plate somewhere

A shame it does not seems solvable..maybe it could be worth talking to a toyota workshop if something can be done with the ecu.
The positive side with my fridge is that it only draws about 18W when the compressor is active, and that it is active only periodically, like an ordinary home fridge.
The model is waeco cf-18 and I can really recommend it!
Over and out,

i take my advice from my local sparks as there is nothing more annoying or embarresing than a flat battery at the end of a lovely day out. (i have got several T-shirts)
Amp hours is the important thing, and how much below the ambient temperature a fridge or coolbox needs
to keep something cool or work to achieve that temp.
Your one is probably very efficient, The Average Amps per hour looks good on your one.
mine are not & use quite a Draw on the battery, but they suit my needs and aseage.

BTW, the outlets are rated for 10 amps and each circuit is fused at 15 amps. I found that the coolers using Peltier effect chips use a tremendous amount of current, and they seem to pull more current as they age. My little cooler put a huge strain on a 12 amp power supply. The original poster's cool box has a compressor so it may not use as much power, but I would not leave it running in an idle vehicle for more than an hour or so, or you might end up with a flat battery.
Here's the link to my 12v outlet mod:
