Every time I see a new 12V appliance that comes with the male cigarette lighter point, I cringe. I absolutely despise them, and you should too. They are the single most useless plug ever to grace this earth, and can cause you a lot of heart ache.
They don’t stay in
My biggest gripe with cigarette lighter plugs is the fact that you only have to hit a tiny bump in the road and they will stop contacting, which in turn means what ever you were running, is no longer being powered. Of course, when the plugs are new they work OK, but over time they lose their spring and become totally useless.
I lost count of the number of times in my 80 series where I pulled into camp to find the fridge had turned off because of the cigarette plug. They wobble loose, and often loose their spring tension over time.
Compare them to an Anderson plug, and you have chalk and cheese. Good luck trying to get an Anderson plug to wobble apart – you have to physically give it a pretty serious yank for anything to happen.
I have since replaced both of the cigarette plugs for my fridge and freezer to Anderson plugs, and haven’t had a single issue since.
Power flow issues
Cigarette plugs are also terrible for good electrical flow. I constantly had issues with my 150W inverter not getting enough power and faulting out, and also the same for the newer Evakool Fridge.
It would show low voltage, when in reality there was plenty of voltage and it just wasn’t getting through the plug properly.
If you are running anything more than about 2 amp hours, get rid of your cigarette plugs – they are a right pain in the behind. Technically, they are good for 10 amps maximum, but you are really pushing your luck trying to run that sort of current through them.
Do yourself a favour and do an Anderson plug conversion; you’ll never look back!
Hi there, I have a Mazda BT with a female Anderson plug already in the canopy.
So can I cut the cigarette lighter plug off my brass monkey fridge and put a male Anderson plug on it so it plugs straight into this?
Yep, you can, but you need to make sure the polarity is correct and that there is a fuse between the fridge and the power source which is suitably rated.
All the best
