How can you tell if a charger is allowed on Royal Caribbean? Info on cruise approved electronics

Can you bring a “cruise approved” charger on Royal Caribbean? Not every Amazon listing that says cruise or travel is actually allowed onboard. Royal Caribbean prohibits extension cords, power strips and multi-plug outlets. Device chargers and USB chargers are the exception, so I look at what the product actually does, not what the listing calls it. If it adds AC electrical outlets, I leave it home. In this video I show how to check a charger for yourself before you pack, including a real travel adapter that looks confusing at first glance. I’ve also linked the charging options I’ve reviewed in my Cruise Approved Electronics list: https://www.amazon.com/shop/charityky/list/1FDHEBUS7N6TE?ref_=aipsflist #RoyalCaribbean #CruiseTips #CruiseElectronics #CruisePacking #CruiseApproved
