I am doing this with an Inky Impression 7.3” and a Witty Pi L3v7 hat on a Zero 2W. The battery is a 6600mAh from Adafruit. This works great as long as you do the SPI speed fix noted at [Inky Impression 13.3" + Witty Pi + Raspberry Pi Zero W2 not working](https://forums.pimoroni.com/t/inky-impression-13-3-witty-pi-raspberry-pi-zero-w2-not-working/28495)
