Is it possible to connect the Nintendo Switch to a portable monitor without a power supply in the car?

I gave my 3 children a switch for Christmas. The display is so small that you can't play with it without a TV. Since I think it would be nice for longer car journeys if you could gamble there together, I would like to put a portable monitor up to 14.5 "for this and connect the switch via HDMI to it. However, as I understood it, it is not possible to do this without a power supply via a socket, right? The monitor should be rechargeable as well as the switch, at least I thought. Is there any way to implement my project?

There are certainly such screens with automotive power cables, which is then simply plugged into the cigarette lighter.

Without an external power source, this is likely to be difficult unless you really find a battery-powered device, but if it does exist, it will certainly not be cheap.

The question is how much power such a monitor needs. It can possibly be operated via the cigarette lighter.

Shouldn't be much, considering that even the 40 inch TVs now consume only a fraction of the previous TV sets.

Cigarette lighter would not be a problem but do you think the switch is enough? And what do I use to connect a suitable cable to bypass the dock. I would also have power banks for the screen 🤔. I thought the switch doesn't need anything because it works as a handheld but that's probably not possible…

But don't forget to worry about where to go with the screen. Not that one of the 3 children sees nothing because the part hangs too far to the left or right.

May or may not.

You should already know exactly.

The 12 V electrical system can deliver a maximum of 13 amps.

A fully charged battery is enough for the switch. If it's for really long journeys, then maybe a kind of multiple socket for the cigarette lighter. The switch gets its power via a USB-C cable, if I'm not mistaken. Something like that should already exist as a vehicle connection cable. It's best to search for "Nintendo Switch Kfz" on google or amazon. Every bet that there's something to be found.

That's probably true. But for devices that are specially designed for mobile operation, I guess that shouldn't be a problem.

It should also be borne in mind that the 13 amps apply to all consumers together!

So if you add a switch and charge a Navy and a cell phone, there's not much left for the screen.

The switch dock / the switch must be connected to the power! Unfortunately, the switch can't be connected to a laptop or only via "expensive" detours: /

I just googled that and you can only charge the switch in the dock with the switch cable (claims of the switch / dock: 5V @ 2.6A for a total of 39W). Therefore you would need a power bank / power generator with plug / AC connection (but then they also cost 100 euro upwards). It unfortunately fails because of the current.

So no that doesn't work (so easy), it would make more sense to buy another Switch / Switch Lite. Or a laptop with controllers and a few cheap multiplayer games.

Have fun playing anyway!

Automotive power cables for the switch are actually available for 12.99 and I can also find screens with the same power connection.

Should be checked beforehand whether everything is packed by the load, as Exxonvaldez noted.

But basically there's the possibility to solve your "problem".

The monitor causes fewer problems than the switch itself. It can't be loaded with USB in the dock, unfortunately. Comes too little volt (switch needs 15V as far as I know).

As far as I understand the principle of the switch, you can play well with it if everyone has one.

That is the idea.

With a monitor you only have a split screen, right?

Yes that's true. The switch supports a local wireless connection and also an online connection. The questioner has only one switch.

With a monitor, the game depends on how the screen layout is. Some games have a split screen, others have a full screen.

But you can also connect a switch to a TV and then connect other switches wirelessly, so you can look at a large screen together or at your own switch.

The questioner has only one switch.

This is (I think) the real cancer damage.

Thank you, that's how far I've come in my research so far. I was hoping there was still a way. What I do not understand is why the switch can charge alone and can also be used without a cable, but a power connection must be available in TV mode.

I have never seen a monitor with a battery and these monitors, which can be tied to the headrest, are not much larger than the screen of the switch.

But you could use a normal monitor with an https://www.conrad.de/de/p/voltcraft-wandler-msw-150-12-g-150-w-12-v-dc-230-v-ac-dosenform-fuer-getraenkehalter-1277756.html?WT.mc_id=google_pla&WT.srch=1&ef_id=EAIaIQobChMI6fvA2cH45gIVGs13Ch2LWQAOEAQYDCABEgKNivD_BwE:G:s&hk=SEM&s_kwcid=AL!222!3!367270211652!!!g! Operate. You only have to think about how to attach the monitor in the car.

The switch has a USB-C port for connection to the dock. I haven't tried it yet, but theoretically it should work if you connect the switch to the monitor with a simple https://www.amazon.de/...075V5JK36/. The dock of the switch shouldn't be much more than a USB hub that distributes the USB port of the switch to the various ports on the dock.

For me it's about socializing together. I only bought games like that. My daughters always feel sick when they play on their trays. So I thought a big screen in front of them where they wouldn't look down would be better. What I still don't understand is why the switch works normally with a battery but connected to the screen does it need external power?

No idea.

Is that so?
