How long would a fridge work on 12V for ?

[sternal]

My portable 3way fridge has 12v option how long would it last on leisure battery ? Bearing in mind its only the fan, almost seems pointless as the campsite has a freezer that I can freeze ice packs etc.

Thoughts

If it is the more common type of fridge (as opposed to the rarer and much dearer "compressor" fridge) it will only last a couple of hours. They use about 8 Amps of power, which is in a similar league to leaving your headlights on.

ice packs it is then

Tis normal to run them on gas when camping. They don't use much.

The 12 Volt operation is supposed to be wired to a relay so that it can only run when the engine is running, thus not draining the battery.

I know just dont fancy using gas this weekend means changing regulator round etc ?

It isn't. There's a 12v element - often about 75w - to generate the heat that then cools the refrigerant. On mains, it uses a 240v element. On gas, it's the flame. The refrigerant circuit is the same for all three, only the heat source differs.

I stand corrected...

I've got an Mobicool electric coolbox as opposed to a fridge - similar to this one - http://www.worldofcamping.co.uk/mobicoo ... -230v-2483" onclick="window.open(this.href);return false;

We've been impressed with how long it lasts without hook-up.

Admittedly, it draws about 4 amps on full power but the beauty of it is that there is an "eco" mode which keeps things a little less cold but burns much less power - you hear it clicking on and off - it seems to be on for about 1 minute in every 10.

I've got a couple of leisure batteries working in parallel and the coolbox on eco has lasted a 48 hour trip with normal use of lights etc.

Looking at the spec of the one I have linked to I can't actually see the "eco" function so don't buy that one without checking.

Hope it helps anyway

I have a Berger 3 way coolbox (same a Tristar you can buy from Amazon, draws 6.5A). I think my leisure battery is not in the best condition (80Ah Banner Energy Bull), but with a battery protector (Conrad MW 728) it works for a bit over an hour. Maybe one and a half.

Are you sure? So are you going to use your 12V option instead?
All this stuff has been covered so often before. Check the archive. Thanks again. You'v been sorely missed!

No to your answer !

I left th fridge at home and we are using icepacks with a nice box as the campsite has a freezer .

Any way I understood what I meant and that's all that matters !
