Use adaptor to plug 12V DC fan into house AC?

Hi, I want a small AC fan, but I couldn't find one in this small town. So I got a small fan that runs off a car battery(Plugs into the lighter).

It says only 12VDC and 12W on the fan.

I have an old computer dc-ac adapter. It says, AC input 110v  .85A max.  DC output,  12V DC, 1.5 A It has a big transformer in the middle, I'll upload a photo.

If I splice the 12 wires onto the wires in the fan, would that work? I mean, I know it would work, will it last? Will it burn the house down?   Thanks.adaptor

The AC adapter is probably a switching power supply and does not have a real big filter inside. The fan may work or may not. The output voltage is also too low by a bit.

Obviously the fan should draw less than 1 Amp.

Safety demands a proper DC power supply that puts out 13.6 volts filtered DC and has a safe ULC AC plug in to house power.

@mel200 - Thanks and good 13.6 V DC power supplies are pretty easy to find. I have couple in my basement shop. Good luck getting one - it should be no issue.  Pyramid make good general purpose power supplies.
