Such hardware exists, i remember i wanted to get something exactly like that for my Windows Mobile 6. 1 device back in 2009. It was like a laptop you could dock your HTC Tytn II into and it would switch to a larger 14 inch laptop display while recharging your phone. Basically just a laptop shell and battery. 👍 Manufacturers will probably start offering these again after Android 16 fully rolls out widely

"smartphone docking station with big screen and recharging
Docking stations that include a big screen for a smartphone are typically "lapdocks," which provide a screen, keyboard, and trackpad, using your phone as the processor. Alternatively, you can use a standard USB-C docking station with a portable monitor. Most of these setups also recharge the smartphone while it is connected.
Option 1: Lapdocks
This all-in-one approach transforms your phone into a laptop-like experience and is the closest modern equivalent to the original Motorola Lapdock.
NexDock: Offers a range of lapdocks that function as laptop shells, using your smartphone for processing power and including a built-in keyboard, battery, and screen.
UPERFECT UDock X: A 2-in-1 portable monitor lapdock that can connect to your phone wirelessly or via a cable. The built-in battery can also charge the connected device.
How it works: You connect a compatible phone via USB-C to the lapdock. The phone's desktop interface, like Samsung DeX or Motorola Smart Connect, is then displayed on the larger screen. "
"Option 2: Smartphone + USB-C dock + portable monitor
This modular approach is more flexible, allowing you to choose your preferred screen and docking hardware.
Setup: Connect your smartphone to a USB-C dock, which is then connected to a portable monitor. Many compact docking stations will be sufficient for this.
Portable monitor: Brands like Arzopa, KYY, and Lenovo offer a variety of portable monitors that are lightweight and have USB-C video input.
Docking station: A simple USB-C hub is all you need to add connections for power and a keyboard or mouse. For more demanding use, a higher-end dock will provide additional ports and more powerful charging.
Benefits: This offers more portability and a wider choice of screens. You can use the portable monitor with other devices, such as a laptop or game console.
Key features to look for
No matter which option you choose, your phone must support a desktop mode feature.
Samsung DeX: A software platform on flagship Samsung phones that provides a full desktop-like interface on an external monitor with resizable windows and multi-tasking support.
Motorola Smart Connect: A desktop and multimedia platform for compatible Motorola smartphones.
Android Desktop Mode: A native, though often experimental, feature in Android (version 10 or later) that can be enabled in the developer settings.
Limitations to consider
Performance: The speed of your desktop experience will be limited by your phone's processor. It is suitable for light productivity tasks but is not a full PC replacement.
Compatibility: Not all Android phones support a full desktop mode. Check that your specific phone model works with a "ready for" feature like DeX or Smart Connect.
Wired vs. Wireless: A wired USB-C connection is generally more reliable for video output and charging than a wireless connection. Wireless setups may use Miracast and Bluetooth, which can introduce lag. "
