You can charge the Apple Watch using the USB port from the ship with no problem. Your phones should charge overnight using the USB ports, but if you want to charge faster, use the charger that came with the phones or a multi-port USB charger (I use Anker chargers of various vintages and descriptions) and plug it into the 220 outlet with a suitable adaptor.
I had an iPad, a MacBook Air, an iPhone 13, an Apple watch, and a USB charger for my camera batteries; my wife had an iPad, an iPhone, and a camera battery charger that had to plug into the wall, so we used all the outlets. It was much easier than on most ships!
