HELP: Waeco fridge and power systems in sedan

Before everyone jumps in and says you'll be killing bambi if you run your fridge from the cig socket, yes you can. I have done it many times with my 35l waeco. All you really need to make sure the plug is secure and check on it throughout your trip as it can come loose. When I would stop every few hours I would check the fridge is still on. I now have a wireless temp unit so I can monitor it from the drivers seat.

Fridges only run at about 5-6 Amps so your 10 Amp circuit can handle it. Just be aware not to run too many devices of your cig lighter circuit as even your phone charger can draw 1-2 Amps so it all adds up.

I am no auto electrician, so don't know if the wiring in the vehicle will be big enough, but a suggestion, why not plug the weaco battery pack into the cig lighter, this will then be recharging as you drive along, and plug the fridge into the battery pack.

Hi there Hayley,
I started out exactly the same ie: Waeco fridge and battery pack.
I tested the battery out when I got home and it lasted around 24 hours with low temps during the night and around 20 degree day. This will change dramatically with warmer temps. I once used it on a day of 40 degrees and the battery lasted 5 hours.
I used to what Baz said, that is plug the battery into your cigarette socket of the car and run the fridge from the battery at all times. That way when you stop the car, your fridge will keep running off the battery. The battery will take around 3 hours (+ or -) to charge if you plug it in while you're driving. But that will depend on th fridge load of course. If you run the fridge inside the sedan the load will be minimal because you can run your air cond on warmer days. If you plan to camp up for several days you can run your fridge straight off 240v at a caravan park, so you won't need use your charger all that much. Ben is also correct. Don't worry about wiring, you fridge will run perfectly straight off your battery. The threads that you have read regarding wiring thickness etc are really more based on charging auxillary batteries, or running fridges in trailers and things. Your set-up will work and is a great starting point. As I said it's how I started and you will find that the whole concept of travelling and camping will become extremely infectious. Once you get the bug, you will then want to improve your systems.
Hope this helps.

A 80ah sealed deep cycle battery costs approx $150 or so(maybe a bit more), a battery box to house it in another $60 or so , the 36ah Waeco power pack $330.....I know which I would prefer and you can still charge the 80ah battery from the cig lighter socket...cheers and good luck
