Would there be any issue charging iPhones/iPad Mini via this type of USB port?
Similar to this

Home Depot Link

I'm thinking there wouldn't be, but decided to ask since I've used only Apple chargers in the past.

There are two concerns.

1) location. Running USB from the wall requires some long wires, which make a mess

2) amperage. Anything ipad + retina prefers 2 amps. Check the rating, one like this shows dual 2.1 (good):

I use a power strip with USB that clamps to the table. Keeps the other wires nice an short.

Q about amperage.
The specs on the link I included says 3.3 amp for USB charging power.
Is that a concern? To much available power. Will iPhone/iPad regulate that?

No need to regulate. 5V matches.

The higher current is not an issue.
