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.

These things aren't mutually exclusive. Once upon a time, batteries were generic and fit some standard form-factor. You could swap batteries between devices and often did! You could even connect your device to a pack of batteries, and swap out the batteries within the pack.

240W max is very little when it comes to hearing up water, and most powerbanks don't even do more than 100W output. That's more in the range of those swappable tool batteries.

The Ikape Cera+ can heat water from room temp but it can’t do this many times.

But in many environments you don’t have to heat from cold. There’s often a Zip tap or kettle to get you most of the way.

But maybe the internal battery can deliver more power directly to the heating element.
