I never said they were equal. If I gave that impression, I’m sorry. My point was, given the advantages and disadvantages of each, I’d pick the power bank. I’d like to have both. I’d like to have SDcards, I’d like to have headphone connection. Hell, I’d like to have PCMCIA or PC Express or aaaaaanything internal. I’d also like a physical keyboard but not all battles can be won.

When you do these things, does it matter to you if your battery sits at 3 percent (charging from a power bank) or 100 percent (switched in a new battery). Again, I’m not saying either is perfect but they both have advantages and I’d (personally) take the power bank over powering my device off, switching in a semi-proprietry battery I’m, turning the device on and getting a (presumed) 100 percent right away.

Once you switch device, those proprietary batteries are useless while the power bank travels with you. Again, neither is perfect. I’d like both options available.

Does 3 percent or 100 really matter? If it does, I am wrong. Does it have downsides? Sure as shit. Everything does. I’m trying to wheigh upsides and downsides evenly. I agree, I miss some things. But easy of use, comparability, transferability, easability… Nothing is perfect. SDcard, head-phone jack… No fair alternative so far.

As much as I miss user-replacable batteries, I’d argue, for your example, a non-device specific power bank (or five) is simply a better, more practical and less wasteful option. Especial if rechargable with standard usb-c and some sort of QI built in. I do miss microSD for a lot of reasons though.
