For the Raspberry Pi Zero (W) there are now the most important accessories in reasonable size at AliExpress, for example that 1.54-inch color display GamePi15 with loudspeaker, buttons and battery for plugging onto the Mini RasPi. The power supply for the single-board computer can be taken over by the usable battery cell (Li-ion battery in AA format). Fully mobile operation should be possible, not just as a game console.

Full-color display with 240 x 240 pixel resolution, sound and battery charging circuit the size of the Raspberry Pi Zero
A charging circuit on the board allows you to recharge your batteries via the USB port without having to remove the supplied battery cell. Four LEDs keep you up to date on the state of charge. Ten buttons are available for control tasks via the GPIO pins. A loudspeaker along with an amplifier and headphone output make the display a complete monitor. The price is 22 euros.
The is also in zero format 4x USB hub For about 8 euros: It is simply screwed under the Raspberry and connects by itself with spring contacts to the board electronics. When powered by a USB power supply, up to 2.1A current is available at the sockets. The hub also includes a battery connector for mobile power.

A 4-way USB hub that is screwed under the Raspberry Pi Zero: the data lines and the power supply are tapped via spring contacts.
Since the hub is located under the RasPi, all GPIO pins remain accessible.
It is smaller than a fingernail Raspberry Pi Zero camera. The electronics are not located on a circuit board under the camera sensor (an OV5647 with 5 megapixels), but on the flat cable.

This camera probably has space everywhere because the electronics have been outsourced to the cable.
The maximum image resolution of the almost 10 euro expensive camera is 2592 x 1944 pixels, as video formats 1080p30, 720p60 and 640 x 480 pixels with 60 or 90 frames per second are possible. The viewing angle of the lens is 72 degrees.
