Milwaukee 18 volt DC to 12 volt DC

This video is a simple solution for converting a Milwaukee 18 volt DC to 12 volt DC.
The adapter shown is available as a genuine Milwaukee part. It comes with a USB outlet and a 12 volt outlet for the Milwaukee jackets. Quite a handy little device for charging and things with USB. But what about 12 volt items?
So I found a random plug that fitted into the 12 volt part of the adapter that's used for the jackets. It happened to be and old 9 volt charger for something, found in a box of chargers. So 240VAC to 9VDC, of course we are only interested in the plug.
I had a mutli 12 volt DC outlet in the car. Available from any auto shop or eBay.
I cut the end off the 9 volt plug keeping plenty of length. Stripped both ends keeping them apart. Plugged this into the battery adapter on the Milwaukee battery. Noted which was + and -. Cut the end off the 12 volt multi outlet plugged into the car outlet did the same and noted + & -.
Slipped heat shrink over, matched the 2 + & the 2 -, twisted together and soldered. Then shrunk down the heat shrink .
Tested and I was getting 12.2 volts DC at each outlet as per the video.
In line crimps would work in Lou of solder. The Milwaukee adaptors are half the price of the genuine from China. I used Aliexpress.
Might see if it will run an Engel next.
Like, or don't. Comment or don't. Will try to answer any questions.

Hi Keithy007. Wondering if you tried running a camping fridge yet? Love the idea. I've ordered 2 of these and was going to make a fridge cable splitting into two connections to run both batteries together and hope that is enough amps to start the compressor.

Hi. What is the name of the socket please? I cannot find it on ebay. I think your socket have converter inside that convert from 18v to 12v. I see ebay 12v to 12v socket directly no converter. Thanks for your reply

That 12v outlet is week, if you try to put a big load you will burn it.
