I actually purchased this to replace a slightly older unit with 6 ports and a power cable attaching the unit. The problem is that charging has evolved and I very much enjoy the small size and power delivery options in two of the ports. Makes easy work of my five or so items I regularly travel with. So far I’ve used I. Europe and the Caribbean without issue (both 120 and 240 volt). I’d step up one level if you traveling with a laptop, but I purposefully leave the laptop at home.
