I have about 30 different keyboards. Spending any amount of time on Massdrop and Geekhack will do that to you.

I too have thia tendency to buy power banks.
Now I have 2 li-ion 10.000 mah (MI) and 3 li-poly (ZMI). I always make the "one for me and one for my wife or another family member"-excuse, while in the end I end up hoarding them for myself.
They can also be useful as a last minute birthday present or may be you could just add a timer and diy a handmade bomb with the combined amp capacity.

you just like big, thick, black things

Same boat as you OP, I got 4 powerbanks. If I had more money i would've bought a 5th one with 50k mah, just to charge my kikephone. I also bought a solar pannel to charge my banks, jews gotta jew.

You never know when you need to step down some voltage.
