Not the most comfortable but if you get one with usb-c pd charging, there are quite a few powerbanks even with 100+ watt now.

I used it once to use the in browser bug report thing to request that they support immersive WebXR on linux.

Because I can log into the sync feature without the browser logging me into every single google service automatically with the same account.

Also the Firefox Multi-Account Containers extension.
