Quite useful. A lithium battery pack with engine jump starter, light, and tyre inflator.

Got this last winter to help with engine starts in extreme cold and now I can go inflate tyres without having to bring them to the compressor or struggle with the bicycle pump (which is fine on a small tyre, but tedious on a large one).

Also can charge USB devices if need be.
