1: The Power Axe beats the Chainaxe, mostly because, while it never says so in the novels because then it would be unfair, if the Chainaxe does not have a powered field like the Chainfist, the Power Axe will cleave right through it as if it was air.

2: Power Weapons use a stabilised fusion core that allows them to be fully active for up to several years. Source is the second Salamander book in which a Chaplains Crozius fusion-cell is destroyed and thus his weapon (spoiler!) should not have worked. But the Emprah was all like "Dude take this energy for your weapon to strike down the Wych"
