Timbo, have had my 45 ltr Evakool for about 2 years now and love it, never had a drama with the fridge and would recommend to anyone. The only thing I had to do was run heavy duty wire to power it as it didn't like standard "spottie" cable, but it will run for about 3 to 4 days without starting the car. Works great on 240 and 12 volt power, although it is always on 12V. You wont be disappointed mate, go for it. Peter
