Is there anything special about RV electrical outlets?

I'm thinking about adding a duplex electrical outlet in my outside storage area to use as a charging station for my cordless drill. I can easily get to the wiring and which runs along the top of the storage space and goes to a bedroom outlet. I pulled the outlet out to look at the connections and found that it is not like typical house outlets and I can't just tap on to the terminals. It's no problem because I can splice into the wiring underneath. But I was thinking of replacing that outlet with one that had USB ports to charge the phones. I was just wondering if there is something unique about the outlets other than maybe just quicker to assemble as the unit is being made?
