MacBook Pro mobile power

I just wanted to let ya'll know about http://www.amazon.com/gp/product/B00...00_i00_details before it disappears. This is, as far as I know, the only reasonable solution to powering a MacBook from a DC source without using an inverter. I just bought two of them, and they happily charge and power my computers. What else is there? (Maybe fewer super-bright annoying LED lights. That would be nice.)

MikeGyver (MCT, Inc) has 12V power supply adaptors / cables for all Mac products and other devices, too. A great resource.

Re: MacBook Pro mobile power

MikeGyver gets about $209 plus shipping for a hacked-together solution. The things I bought/linked are factory-built and cost a little more than 10% of that. I'm sticking with my "reasonable" assessment.

Re: MacBook Pro mobile power

If you want to do it on the cheap, I went to an Apple store and asked the genius behind the counter for a bad power supply. He went in the back and got one, I cut off the cord containing the Mac connector and attached it to a $8 18V DC/DC automobile power adapter. Hooked it into the 12V system and it's been working for 3 years.

However, for 30 bucks, that one in the link is worth it. No sense being TOO cheap...

At 85W, it can only power the smallest, 13", MacBookPro.

ciao!
Nick.

Re: MacBook Pro mobile power

I have a new and an older 15" MBP, both of which are work computers and get run pretty hard (eg, the fan runs most all the time). The adapters are still happily powering both.

Re: MacBook Pro mobile power

We brought a mac car charger from eBay for $35AUD works great and you can buy chargers to suit almost any model incl the larger power hunger ones.

Re: MacBook Pro mobile power

I'm looking to solve this problem and ran across this product. Wondering anyone has any experience with it or spies any issues based on it's specs:

Amazon.com: Ultra Portable MacBook Super Fast Car Charger/Adapter 45w/60w/85w (WeCharger NEW Generation) for Mac Book and Pro Auto/Air Power Cord (Built-in Transformer, No MagSafe Needed): Computers & Accessories

The price is right and the reviews look strong.

It's pretty weird that there are so few solutions for this out there. I stopped by the Apple store the other day and after talking to someone at the genius bar they were as stumped as I was about why there is no popular product out there that charges a Mac off a DC power supply. You can write it off to a patent issue, but it's not like this is an unusual need.
