I haven’t tried that Samsung tablet but I recently got a 11" tablet and a 13" tablet, each with a magnetic connected keyboard and I returned the larger tablet as it was a floppy awkward mess.
Tablets work upto 11" but larger than that you need a rigid hinged laptop.
The convertible concept is where you add/remove keyboard and use the tablet in landscape or portrait and more use of a stylus. But convertible keyboard is a dangling thing with magnets not strong enough when you use larger than 11".
Travel chargers are an entirely different set of decisions. Your travel computer tends to be smaller to fit in a bag , on a aircraft seat small table, etc, so they need less powerful chargers which do need folding pins.
I’m about to do a 3 day trip and I’m taking my UK folding pin dual socket 33W charger with a convertible 11" tablet and a 20Ah Powercore, a short and a long USBC cable.
Android isn’t that brilliant either for landscape. I’ve used Android tablets for 11 years but this year I moved to Chromebook as it handles multitasking and landscape better while still running Android and Linux for those few apps which ChromeOS doesn’t do.
