help with waeco fridge in subaru

These sockets are deliberately connected to the accessories circuit so that it's a deliberate act to keep them active when the engine isn't running. Low voltage cutouts cannot be relied on to turn the fridge off when the battery voltage gets low. Thermoelectric fridge/warmers are pretty power hungry, so suggest simply leave the accessories switched on if you really need to keep the fridge running during brief stops. The other option is to have an auto sparky connect the sockets to an "allways on" circuit, but I'd be sure to carry some jumper leads if you go this way!

Buy a power supply module and cable ($100-200) from Bainbridge (spelling/ name?) or Waeco and have it fitted.
Bainbridge one from memory has volt gauge, numerous power outlets and maybe low voltage cut out.
Most importantly both have heavy duty/ proper diameter cabling and switch to enable working direct to battery or via accessory switch.

My suggestion, assuming you only have a little car cooler, would be to buy a small AGM battery say 18-20ah and have it connected between the fridge and the accessory socket. Done correctly it will be being charged when the car is on and will be discharged by the fridge when the ignition is off. The battery won't charge perfectly and have limited number of hours it will work, but no fewer, I would have thought, than how much you might want to take from your car battery. You might be able to set the fridge, depending on the model, so it will only take a limited amount of juice from the battery.

AGM because it can sit at any angle and it gives off no gas while charging in the boot of the car. If you can restrain it though would be good as it has some weight, say 5kg-6kg, and would be lethal in an accident. Don't forget to protect the wires with a fuse.

These little firdges do actually use a fair bit of battery juice as they have minimal insulation and designed to operate continuously. They are really only designed to be used when the car is on. I doubt it would keep cool for a full night and then take a fair bit to charge the battery back up.

I used this set up for a little waeco fridge and a Waeco Fridgemate battery that was designed to be rigged up as I suggested. Waeco don't sell it anymore but you can still buy just the battery and rig it up yourself for 1/3 the price of the fridgemate.

thanks to all for your help. i will go to an 4x4 auto electrician and ask him. many thanks to all once again, anton safe travels to all
