The Switch 2 is bigger than the original Switch and uses a new storage format, so a lot of old accessories do not carry over. Original Switch cases and screen protectors are the wrong size, and the console stores games only on microSD Express cards — ordinary microSD cards will not work for game storage.
In order of importance: a microSD Express card if you buy digital games, a case and screen protector if the console leaves the house, and a Pro-style controller if you mostly play docked.
The built-in storage fills quickly with digital games. Only microSD Express cards work for Switch 2 game storage; check the card says 'microSD Express', not just microSD.
A hard-shell case made for the Switch 2's larger size, with game-card slots and room for the charger. Original Switch cases do not fit.
Keeps the larger screen free of scratches from the dock and from bags. Make sure it is cut for Switch 2.
Full-size grips and sticks are far more comfortable than Joy-Con for long sessions on the TV. Nintendo's own and third-party models are available; look for back buttons and drift-resistant sticks.
A USB-C power bank with enough output keeps it going on a flight; a spare charging stand keeps the main dock by the TV.
Adds proper handles for handheld play, which the thin console lacks. Check that it leaves the Joy-Con release and vents clear.
A quick check of what you can keep and what you need to replace.
