All that means you need bulky clothing to hold the extra's.
I have a nice stylus pen for my ZU ... i do not take it because its not convenient ( especially in the summer when you do not have a jacket on ). You forget it a few times and those few times become a lot of times and ... you just do not bother anymore.
The solution is very simple: Have a bigger battery in your phone from the start. It does not add a lot of bulk ( some smartphones/tablets even have wasted space! ). But yea ... then you run into the same problem with everybody making bigger and bigger phones but very tight batteries.
Well it depends on where and when you use it...every night i always change my phone and pb to full...if your on a travel, or got a car, you can put it aside just used when in need...no need to carry it with you all the time, just put somewhere near...for me, i always carry a belt pouch to carry my power bank...
Power bank like 10000mah can charged 2 or 3 times to full...so if you use it once or twice, you still have time to charge your pb...and it charge ypur phone quite fast...
Well its me, and in my country, we always think pb is better then extra battery...cause battery even bigger it is, tend to drain a lot and fast...a pb is like a wall charger. You put it on, and can stay a more longer then an extra battery...
Maybe its a little inconvenient for some cause how big and heavy it is...but for me, i don't mind...
