Power-storing (eg: Armor of Exploits) questions

[Black Knight Irios]

Does anyone know if this armor follows the regular rules for action point expenditure?

For example, since you can only spend one action point per encounter, does this mean you can either use an action point to take an extra action (the regular use of an action point) OR you can burn an action point to activate an encounter power stored in the armor?

Does the armor description state that you can spend more than one action point in the encounter? - No, it does not.
Therefore the answer is: You can still use only 1 AP/encounter.

This might sound like a stupid question, but does "storing" the power expend the power? Or does merely having the power on the character count as "storing" it (i.e., can you store an expended power)?

I guess it's not clear to me what "store" means, in this example.
