Any 240/12v inverter will do the job provided you have the correct connectors. I can't remember but I think that Evakool has a ciggie lighter plug (male) that you can convert to a Hella plug by simply unscrewing the end off.

you mean transformer and it needs to be a regulated supply with an amp supply similar to the evakool one or better. I doubt you will find anything cheaper unless its second hand. I use a trannie I used to use with the amatuer radio Cos it was there and regulated and plenty of grunt.

I use the Mobitronic inverter with my Waeco and it doesn't require a cooling fan or any such other device. I was also told by Waeco that basically any 12/240v inverter will do the trick. As both fridges run the same Danfoss compressor I can't see the need for anything special as all it is doing is converting/inverting the 240v from the mains to 12v for the fridge. What could be simpler than that?

Spot on mate, except don't you mean 240/12 not 12/240.

Yep, maybe I'd had one coldie too many at that point but glad you agree that any 240/12v inverter will power a fridge from the mains.

Don't want to sound pedantic, but a confusion of terms could lead to a disastrous outcome here:

To change 12V DC to 240V AC, an INVERTER is used.

To change 240V AC to 12V DC, an adaptor is used.

Yes, a quick check on the internet says that you're right - I got the terms back to front. A power adaptor that converts 240v to 12v is what is needed. And it's not pedantry. I looked at a can sized Waeco inverter in Anaconda the other day thinking - I might get that for my fridge - would've have been totally useless for my needs.

The EvaKool adapter is rated at 7.8A continuous and 120W (10A) peak. It also has a fan to keep it cool. I would look for a 240/12V adapter that meets these figures.

Why not contact Derek on here he sells fridges and power supplies amongst other stuff and is good to deal with.

Keep it in the family

Crasch,

The thing you need is a mains powered 12V power supply, not an "adapter" or "inverter". They are readily available from Jaycar and similar places, delivering 12V (or some 13.8V, which can be useful for battery charging too). A 100 watt one should be adequate, and from Jaycar will cost from about $70.

Er? A mains-powered 12v power supply, not an "adapter"? A mains-powered 12v power supply IS an adaptor.

Er ! Yes you are right too. I would refer to an adaptor/er as a socket / plug type fitting but yes it can be referred to as a power conversion device too.

An adapter or adaptor is a device used to match the physical or electrical characteristics of two different things so that a connection may be made between them.

An adapter may be very simple, connecting one kind of plug to another kind of socket, but not changing what passes through. One example would be a garden hose, which normally has threads that screw on, but can be attached to an adapter which allows it to snap easily on and off of faucets, other hoses, or attachments. Likewise, a serial port may require an adapter to connect between the old DB-25 type and the later DE-9 type, which have 25 and 9 pins (respectively) but only 9 wires each.

Other adapters may include a device that changes what is passing through, such as a transformer that adapts household electrical current from high voltage (100 to 240 volts AC) to low voltage suitable for consumer electronics.

Well said Derek. I was maybe sticking my neck out by saying this gear is not an adapter. Of course it is - like so many other things. That term is being used increasingly to describe gadgets that change voltages. But it's a generic term which as Derek says, covers just about anything you can name, from nuts and bolts to plumbing, electrical, even people - a person who readily fits into new circumstances could be called an adapter.

A quick google search found over 8000 adapters for sale, but less than 700 power supplies.

Guess I'll have to adapt to simpler more generalised language!

I have the Evakool adapter it also has a battery charger set up, $150 is cheep for the proper device to use.

Cheers Steve.

Super Cheap have a 240v to 12v power pack. The 12v end is a female cigarette lighter type. Cost me $49.95 earlier this month. Regards G.T.

Dick Smith sell a 13.8 volt 23 amp Power Supply for $99 - very good value.

You'll have lots of reserve current for other 12 volt appliances.

Since it's regulated to 13.8 volts (adjustable) you can even use it to float charge batteries to maximise their life between trips.
