Mobile power for the road warrior.
Ever wished you could keep your MacBook or MacBook Pro alive on those long road trips? We have the solution! All you need are a few readily available parts, some basic soldering skills and a few hours of time.
Collect The Parts
To complete this project, you will need:
1. Kensington AC/DC Power Adapter
2. MagSafe Power Adapter.
3. Power Jack & Power Plug 5.1mm OD, 2.0mm ID (Radioshack, etc…)
4. Soldering iron, electrical tape, shrink tape, Swiss Army Knife, and common tools.
The basic methodology is to splice a connector into the cable of the MagSafe power adapter. The Kensington unit can then be used to provide the proper 16.5V to the MagSafe connector and power the MacBook while on the road.
Once the cable of the MagSafe adapter is cut, the loose end (with the MagSafe connector) will be terminated with the power jack. This will enable the MagSafe connector to be connected to either the original power brick or the new travel power adapter.
The power brick end is connected to the power plug so the two can be paired together yielding a functional (albeit warranty-less) power adapter.
