The iPad charger supplied by Apple supports up to 12W while standard USB chargers are much less, around 3W I think.

That means it takes a long time for an iPad to fully charge using a standard USB charger, probably overnight, and using the iPad while plugged in will stop it charging.

I therefore wouldn't bother getting a plug with a built in USB port in it as it will probably only supply standard USB power so will take forever to charge an iPad.

In addition to the iPad's own power supply, you can buy USB hubs with "high power" ports for charging tablets and there is no problem plugging any device into these as they will only draw their specified power even though the power supply can provide more.
