I am looking to put together a Pi 5, screen, keyboard, mouse, and battery for a portable demo kit. Who has something light weight, can run got an hour on battery, and can stand a little banging around in a car? What did you use? What size battery?
My 15" screen runs from USB so is easy to use from battery. My 21" screen is the minimum readable size for two or three people but is mains powered, a problem from battery. I do have a 12 volt to mains inverter but it needs a big battery as it is inefficient.
I want to fit a Pi 5 so I can add USB disk and things for a demo. The disks are NVMe SSD in USB enclosures. I have a Pi 5 on a board with a breadboard for showing blinking LEDs and similar projects. I also have a Pi 5 with PCIe NVMe SSD which should use less power than USB enclosure.
The alternative is to have a power board, run everything from mains power, and carry a fully charged UPS with enough power for an hour. Or buy a car battery and use with my inverter. The inverter produces 150 watt continuous or 250 peak and uses up to 15 amp at 12 volt. I have not measured actual input amps when stuff is plugged in and do not have a suitable meter. A local shop is offering a good deal on an 18 amp hour glass mat battery.
I guess the weight would balance out. Car battery in one hand and carry case in other.
