What power supply do I need for this mini fridge?

[ProduktionModal]

I got a mini fridge for free from a friend, but it's missing the power supply. I'm not an electronics guy at all and figured it was worth a shot to post on this forum. Can anybody identify what I need, and where to get it? Or where else I can get help? I don't even know if it's able to plug into a wall outlet, or if it's car-only. I live in the US. Thanks a lot!

It looks like that's 12V-version (only) and you can run it of a car battery or a power adapter, say 12V min.5A .. follow this link ..

The problem is that square socket in back of the fridge... I can't find an adapter for it.

You can always try the fig-8 connector (see attached picture) and modify it's "shape" if it's to wide ..
Just measure the distance between pins and the diameter of the pins, if they match you have el-cheapo solution ..

Anything I should know about polarization? If I cut-to-fit as you mention, is there danger in plugging it in the wrong way?
Also, where the heck do I purchase an adapter with a fig-8 end?

That is probably a Peltier Cooler type device. If yes, the cooling/ heating element is the same and does not care for polarity. If you reverse the polarity, the device reverses function.

But the thermostat could be sensitive to polarity. So it is better to stick with the correct polarity. And 12V 5Amp seems to be decent.

Will this work? It appears to have the correct shaped plug.

I think your Fridge input is not probably polarized...Is there any marking?

The mentioned product is 13V one. I would not use it if I were you. why don't you build one?

The connector must be polarized - it says DC and has a hot/cold switch.

Take it apart and see if the wires are colour coded.
