We sailed on Norwegian Bliss, a brand new ship that had a couple of USB ports in addition to the bedside lamps but was very handy for 2 phones, 2 vaporizers, a laptop and a kindle . The only thing I didn't like was that the metal pins couldn't be folded into the device itself for packaging like most phone chargers do. It didn't matter in my package, although I was glad I bought it.
