Recommendation for a display drawpad, one with which I can paint anywhere without a PC or laptop connection. And where can you use Photoshop etc?

I like to paint digitally, with Photoshop on my PC pictures, I use a normal DrawTablet which I have connected to the PC, so without a display. But I don't always feel like sitting at the PC to paint, especially because my PC faxes me too many with memory blah, so I want to get a draw tablet that I can take with me anywhere, and paint directly there, for example on the train the balcony etc, but I don't have the money for an ipad now what do I know what for 10 million euro, you know some draw tablets with which this is possible, even without having to connect it iwo

What really good for not so much money you can't find, the I pad pro is still the cheapest
