A new device makes it easy to power devices on the go.
The Bat Hook is an on-the-go charger exclusively designed for soldiers in special operations. The charger is in the form of a weighted hook with a razor blade in it, strung on the end of a cord. In times of need, it can be tossed over to an overhead power line where its blade pierces the live wire and safely conducts electric current down to the user for conveniently charging their gadgets.
