If you have picked up a Switch 2, the useful question is not what to buy next but what you already own that still earns its place. Nintendo kept a lot working across the two generations, then drew hard lines in three places: the dock, the memory card, and anything cut to the shape of the console. Get those right and the rest of your Switch kit travels better than you might expect.

Controllers: what pairs, what attaches and what charges

Controllers are the good news. Nintendo confirms that original Joy-Con, the Switch Pro Controller and the retro pads sold for Nintendo Switch Online all pair wirelessly with Switch 2 and work with compatible games.

Where original Joy-Con stop short

  • They cannot attach. Switch 2 holds Joy-Con 2 on with magnets and a release button, so original Joy-Con are wireless-only.
  • They cannot charge on it. Nintendo states they “cannot be charged on the Nintendo Switch 2 console”, so use an original Switch, a charging grip or a stand.
  • No mouse controls. The optical sensor that lets a Joy-Con 2 slide across a table is new hardware, so games built around it need Joy-Con 2.
  • No C button. GameChat sits behind the C button on the right Joy-Con 2 and the Switch 2 Pro Controller.
  • They will not wake it. The HOME button on original Switch controllers cannot exit sleep mode on Switch 2.

The Pro Controller is the easiest win

An original Pro Controller is the most useful thing to bring across: it handles anything that does not need mouse input, and charges by USB from the Switch 2 dock. Joy-Con accessories are another matter — straps, the Grip, Charging Grip, Wheel, battery pack, charging stand and Ring-Con fit original Joy-Con only, not Joy-Con 2. Nintendo’s accessory compatibility table lists them all.

Cases, grips and screen protectors are strictly model-specific

Four Switch consoles are in UK homes, with four screens: 5.5 inches on Switch Lite, 6.2 inches on the original Switch, 7 inches on Switch OLED and 7.9 inches on Switch 2.

A protector is cut to one size, so a Switch or OLED one will never sit correctly on a Switch 2. Cases follow the same logic: Switch 2 is a larger console, and a case that zips shut around a Switch OLED will not close around it. Switch and Switch OLED are close enough that some cases fit both, but even those two take different protectors.

Every Nintendo Switch listing on RozGamer.co.uk names the exact models it fits, because this is the easiest mistake to make and the easiest to avoid.

Memory cards: Switch 2 needs microSD Express

Switch, Switch OLED and Switch Lite take ordinary microSDHC and microSDXC cards. Switch 2 will not store games on them at all.

Nintendo is unambiguous: Switch 2 is designed exclusively for microSD Express cards, up to 2TB. Put an older card in and it “will not allow you to save or load digital games or save data” — you can import screenshots and videos captured on a Switch, and nothing more. Nothing is damaged. A system update is needed the first time you use an Express card.

  • Express is a different standard, not a speed grade. Check the card says “microSD Express”. A fast UHS-I card rated A2 or V30 is not the same thing.
  • You may not need one yet. Switch 2 has 256GB built in, against 32GB on Switch and Lite and 64GB on OLED. Express cards cost more per gigabyte, so there is a fair case for waiting until you run out of room.

Switch 2 keeps save data in system memory, and it cannot be copied to a card. Nintendo’s microSD compatibility page covers the rest.

Docks, power and getting online with a cable

The original Switch dock does not work with Switch 2, and no adapter changes that. Switch 2 comes with its own, and Nintendo sells a separate Dock Set — dock, AC adapter, USB-C cable and HDMI cable — for a second room.

Power has a twist. Your old Switch AC adapter can charge a Switch 2 console, but Nintendo says its output is insufficient for TV mode. If no picture appears on the telly, check which brick is in the dock before assuming a fault.

A word on third-party docks

Cheap travel docks are tempting and some are fine. But unlicensed accessories do not go through Nintendo’s testing, and Nintendo will not honour a warranty claim for a fault one causes. A dock sits between mains power, your console and your TV — a poor place to economise.

Wired internet

The Switch 2 dock has a LAN port built in, as does the Switch OLED dock, so an Ethernet cable is all you need. Only the original Switch dock needs a USB LAN adapter.

Games, Game-Key Cards and Switch 2 Editions

Switch 2 plays compatible physical and digital Switch games, which covers most of the library. “Compatible” does real work there: Nintendo runs a searchable compatibility checker flagging titles that are only partially supported or not supported, and it changes as games are patched.

Anything built around original Joy-Con hardware is the exception, though the line is finer than it looks. Ring Fit Adventure and the Labo kits genuinely need original Joy-Con, because Joy-Con 2 will not clip into the Ring-Con or the Toy-Con. 1-2-Switch and Nintendo Switch Sports do run on Switch 2 with the Joy-Con 2 in the box; Nintendo’s checker only flags specific modes that still want an original Joy-Con — the games using the IR Motion Camera in the original right Joy-Con, and the Football Shoot-Out mode in Switch Sports, because Joy-Con 2 do not fit the Leg Strap.

Two newer things to recognise on a shelf:

  • Game-Key Cards. The card is a download key, not the game. You need internet and free storage the first time you play, and afterwards the card must stay inserted. Treat the box as a licence plus a shelf copy, not a cartridge.
  • Switch 2 Edition upgrades. Selected Switch titles have enhanced Switch 2 versions; if you own the original you can buy just the upgrade pack, and some come with Nintendo Switch Online + Expansion Pack.

Neither adds anything on an original Switch, which is why our video games listings name platform and edition.

Headsets, GameChat and the Bluetooth catch

Audio travels well. Switch 2 has a 4-pole 3.5mm jack to the CTIA standard, so a wired headset that works on a Switch, a phone or a PS5 controller will generally work in it, though Nintendo cannot guarantee every product. The Switch 2 Pro Controller has its own jack, tidier in TV mode, and headsets and mics also connect over USB, to the console’s top USB-C port or a dock USB port.

Bluetooth is where the small print matters:

  • One Bluetooth audio device connects at a time, with up to ten remembered.
  • Bluetooth microphones are not supported, so a wireless headset gives you game sound but not chat.
  • Bluetooth audio limits you to two wirelessly connected controllers.
  • It disconnects when a local wireless multiplayer game starts.

For couch co-op or regular GameChat, wired is the better tool. Our guide to choosing a gaming headset compares the connections.

Before you order, do a two-minute audit: keep the Pro Controller, check the model printed on your case and protector, and read what your memory card says. That usually shortens the shopping list. If something arrives wrong, the Consumer Contracts Regulations 2013 give you 14 days to change your mind on most orders, though sealed games must come back unopened — see delivery and returns and our other compatibility guides.

Frequently asked questions

Can I use my old Switch dock with a Switch 2?

No. Nintendo confirms the original Nintendo Switch dock is not compatible with Switch 2, and no adapter changes that, so you need a Switch 2 dock for TV play. Your old AC adapter can still charge the console, but Nintendo says its power output is not enough to run Switch 2 in TV mode. Our Switch range lists docks by model.

Do original Joy-Con work with every Switch 2 game?

Not quite. They pair wirelessly and play most titles, but they cannot attach to the console, cannot charge from it, and cannot provide the mouse controls some Switch 2 games are built around. They also lack the C button that opens GameChat, and Nintendo notes their HOME button will not wake a sleeping Switch 2.

What is a Game-Key Card?

It is a boxed Switch 2 game whose card holds a key rather than the game data. You need an internet connection and free storage the first time you play, and afterwards the card must stay inserted, exactly like a normal physical game. A key icon on the card marks it, and the download size is printed on the packaging.

Can I put a microSD Express card in my original Switch?

Yes. A microSD Express card works in a Switch, Switch OLED or Switch Lite as an ordinary card, though Nintendo notes it reads and writes at standard microSD speeds there. It is a reasonable buy if a Switch 2 is on the horizon, but you pay a premium per gigabyte for speed your current console cannot use.

Prices, specifications and manufacturer support can change. Check the product listing and the manufacturer's own guidance before you buy, and ask our team if you're unsure.
