No USB charge bricks needed while on shore power...
http://eshop.macsales.com/item/Newer%20Technology/PWR2USB/ Cool idea.... I have a few 12v ports added with dual charger jobbers. But this is cool. You can get 15a and 20a outlets too.

Why not use something like this - less than $10 and no installation.
This is what other poster called "wall wart" or "USB brick". Draws power without load, yes. Better to remove when not in use, mostly for safety reasons so that it won't cause problems when you are not there.
I wouldn't worry about extra energy drawn by those flush outlets in idling mode. It draws 0.05-0.2W depending on model, this is max 0.4 AH over 24 hours. If you have 4 of them, it's still 1.6 AH or less. Do you really need more than 4? :)
Wall warts - I would suspect they draw more. Flush mounts sold in stores like Home Depot or Lowes are from Leviton and other brands that have been making residential 120V outlets for decades, they are certified, otherwise stores wouldn't sell it. Bricks from Amazon are made by God knows who, don't expect any standards of safety and quality - but then again, it can be easily removed when not in use.
