Having a battery pack has its uses though. As crazy as USBC is, you can now get a relatively large amount of power from a battery pack.
There’s a bunch of things that don’t need their own battery if they just drew enough power off USBC. I have an office coffee setup. My grinder and espresso maker have their own batteries. But there’s no reason I couldn’t have a single battery pack and just plug both into USBC saving me a ton of weight. (In fact the Lagom Mini 2 grinder is powered straight off USBC with no internal power.)
For phones and cameras, that need their own power source, a replaceable battery is mostly just an end of life thing for me. Because I’d still have to carry a cable or spare battery around.
