Probably that these are reasonable, ordinary and necessary expenses of
your trade or business. That would make your trade or business
that of exercising a POA. And you have a reasonable expectation
of making a profit in this trade or business.
So to make a profit while deducting expenses, you would have to be
getting paid for these POA duties. If, for example, you are a
lawyer who acts as clients' attorney constantly, and bring in
income from your trade, then sure, go ahead and deduct.
If not, I would want to know your theory and see your income from
Time -- no. The value of your labor is never deductible.

Or, take a safe deposit box. If it is used to store items directly
related to taxable income, such as stock certificates, then deductible.

postage, possibly gas if the POA has to travel to see say the person's
broker from time to time.
Unless there is a contract distinct from the POA duties for payment
for labor, then like the others indicate labor cannot be charged or
