Homebox has this capability too, you can generate QR codes for assets and scan it later to identify whatever’s inside.

The current version does have the ability to create QR codes for your assets and scan them later for identification, but I don’t know of a way to scan a new item and identify it automatically.

I think it becomes more useful as you accumulate stuff - I get frustrated when my wife buys crap on Amazon that we already have. So while I don’t have the time or energy to sort everything in our house, I am beginning to catalogue things as we buy or find them in the hope it becomes more useful over time to find things we rarely use and/or avoid re-buying excess items

I would especially advise against relying on battery banks due to the heat, if you’re just going to use it in the car and already going to the trouble of customizing so much hardware I’d find a way to run a power supply off a switched 12v fuse or wire from the car - just convert to 5v/USB power. I’m sure there are generic kits online
