+--- Thread: 12 Volt supply for a MacBook Pro (/thread-741.html)
- boatmonkey - May 6, 2009
Other than the airline adapter that Apple sells (which doesnt work plugged to my 12V socket) does anyone know of another solution for a MbPro with a Mag Safe Adapter
- boatmonkey - May 6, 2009
I found the answer in a related forum topic thread
http://mikegyver.com/ is selling a Kensington AC/DC product that will do the trick in all AC and DC environments
Also for a few dollars more at www.powermymac.com you will find a Lind product to do a DC to DC specific job but I'd go with the first option and get all the convenience of a one stop solution

I have had the Mcgyver Adapter for a year and it is great. It takes a DC or AC or airplane input and charges the laptop in all 3

Can's wait to get mine. And I notice they make a Mac Mini DC supply as well. Might make a permanent install with an old unit I have laying around in the basement

I already had a Kensington supply and I made up the Magsafe tip with a older Mag adaptor, works great.

Barry - I've got a magsafe that has frayed away from the power brick. When I replace it I'd like to cut off the magsage connector and attach it to a 12 dc power source.
a) Seems I could wire it directly to my 12 DC circuit, maybe add an in-line fuse.
b) Could attach to Kensington like you did. What Kensington product did you use? Can you post/email a picture of your final product

check out the hyperdrive guys, do a search in google, I used their solution and ran my laptop for 60 straight hours without a hitch.

I've done just this 2 weeks ago
the braid frayed through the magsafe end of the psu just where it comes out of the block, so bought a new psu for the mac
bought one of those universal 12v in car 80w laptop power adaptors from ebay cost £6
joined the chopped magsafe cable to the cheapo 12v psu, set the voltage switch and plugged it in
works fine

That's really all the Mikegyver one is; he essentially solders on a female connector to the magsafe cable that matches with one of the standard male plugs that comes with the Kensington brick, nothing more.
That, btw, is the weak point in the Mikegyver one - I've had two fail at the female plug he put on. Next time I'll do it myself.

why bother with the female plug?
join and solder the wires, heat shrink sleeve on afterwards, jobs a good un!
- jagasail - August 9, 2009
Well, mostly so you can use the brick with it's interchangeable tips to charge other things. If it's totally dedicated to your Macbook then eliminating the female plug would be a better approach.

Hi, yep, I went to radioshack and purchased the correct jack plug to fit the Kensington tip. No problem soldering to it. I used some heat shrink tubing to get a great fit. I can use the Kensington adaptor either in 12v mode or 110 volt. Another use is the USB tip that will allow charging of any device that uses a USB type adaptor cable, such as my iphone.
