I didn’t see the need for a heavy box dedicated just for power when I can carry along a Lithium Ion jump starting pack in my pocket for a fraction of the cost and a lot less weight than what these things are selling for….but I do like to tinker so I built something a bit different.
The “power box” I threw together has the standard stuff you see on the commercialized versions. USB outlets, a 12v outlet, lights, blah blah blah. Where it’s different is that I picked up a marine stereo with built in speakers off of Amazon and a small car antenna that folds down and built a radio box. I have less than $50 invested into the thing and oddly enough I rarely take it on the ice. The jump starting pack works just as well and isn’t as bulky. I will use my contraption in the woods cooking maple syrup or working in the garden. I suppose I could throw some lithium batteries in it to lighten it up but it still takes up space in my sled.
