"Hack" old iMac to power it from 12V
« on: July 29, 2020, 10:18:21 am »
Hi guys!

First off all, I don't know if this is the right place to get help from other people.
My Idea was to replace the iMac powersupply to, for example add a battery and to make it kind of portable.
I disassembled it about a month ago and took some pictures of the powersupply, let's see if I still have them. I searched on YouTube if someone allready done this but it looks like no one ever had such a stupid idea.

I hope someone more andvanced can help me, so I don't fry my machine.

There is a reason that you have desktops and laptops: power consumption. I mac chugs power, I'm not sure about exact numbers but the PSU should gibe you a good idea of the power rating. If you want to power it from lipo cells for more than 10 minutes, you need a huge pack of them, plus some buck converters to convert to voltages like 12, 5 and 3.3 (I'm again not sure about exact different power lines of a mac, you should measure from PSU). All in all, forget about making it portable. The amount of weight and space the batteries add make that impossible.

You are completly right tbh. Theres no need to do such a thing. But anyways it only uses 12V I think, but still, again the weight of the iMac 12,2, which I have is just allready 30.5 lbs. (13.8 kg).
