power armors do not offer any protection, idk if this is a bug, for example when hit by zombie pigman with advanced alloy armor i take ~1.5 hp damage and steel ranger armor made from same armor with extra thing damages ~7hp. i made armor in survival and tested out in nether, i had a hart attack when i tried to bully gold loving pigs, i barely survived. (same are happening with other power suits)

have you charged them

i am playing with default configs, i could not find anything about armor protection (i have not looked hard)

have you charged them with electricity

(sorry i read it wrong, i thought you wrote changed not charged) yes but i suspect that when i craft them they indicate that they are charged, when i add modification on table they suddenly loose power (this might be actual bug) i have done with all armors except one, it behaves normally, discharging and charging, still gives me effects, i'll try to replicate problem in other world

it still does not work. it would be nice if you could attach power armor battery to regular armor to make attachments on it function like night vision and servos and could be charged like jetpacks with fuel, thats one reason why i needed power armor.
