Being an apartment dweller I don't have room for the big cool systems. You can build a very nice portable system and there's great tutorials for that, however not everyone has that ability and need, or cash.
If you buy this

You get a small tire inflater, 400w invertor, jumper box, and a led light. You can charge it from your car or from the wall.
If you add this

You can charge it while it sits in the safety of your garage or in the back of you vehicle not to mention if the power goes out.
For $125 you get quite a bit of versatility.
Any thoughts?
