Not from Magellan, but auto parts stores and the like sell totable 12V power packs. Most oftent they do have a 12V auto outlet on them.

I have one from Canadian Tire (Canadian department store chain, catering to auto, DIY, home, and garden wares), made by Xantrex, which I have charged with a solar panel (but can be home charged from the wall).
I have a Megellan 3120 that I take and charge from it.
