I should give this a shot. I used to use CHDK so I could use my old crappy Canon into something that would take good time-lapse videos by snapping a photo every X seconds; I miss doing that, though now it's harder because I live in the 'burbs, and there's no particularly spots for that nearby, and anywhere that is a good spot likely doesn't have a power outlet for me to use. I wonder how long I could power my camera from a portable charger?

I used to do it as well with a cheap second-hand IXUS 230 HS. It could run (at least) 48 h off a 7.2 Ah 12 V AGM battery, snapping a photo every 3 s (I used a fake-battery power adapter and a small DC-DC converter.)

Same here. I used to live in a fairly tall building in Manhattan, so found my way to the roof, found an outlet, and would set it up to do timelapses of sunsets over the Hudson.

The camera lens was pretty dirty, so they weren't great, but I enjoyed them: https://www.youtube.com/watch?v=OVpOgP-8c9A

Nearly all Canons have a small access port as part of the battery door, which you can put a power supply cable / through, by design. Don't buy too cheap a dummy battery, the really cheap ones may have very bad voltage regulation. You can get ones designed to work from a USB power bank, or mains.
