I have one backpack I use for everything. I usually keep a 65W USB A+C charger and a 45W Powerbank with a small assortment of cables in there.
Now of course I have multiple USB-PD chargers and powerbanks, however all of those mysteriously disappear when I need them, making it necessary to use the backpack ones at home and being the clumsy dork I am, I always forget them there reducing the backpack charger count to zero. And guess when I come into a situation where I desperately need to recharge \ on the go?
Yep. This is how I roll. I always take a specific bag on trips. That bag has a specific pocket that has 2 spare cords (short and long), 1-2 spare wall chargers and a power bank. All my cars have cigarette lighters with power-delivery chargers and a cable that never leaves.
The only time my phone dies is when I'm out all day, using my phone way more than I'd thought and I'm with people who still use old iPhones so their whole life revolves around lightning still.
