Same for me. I can see this being more useful for people who don't typically carry around handbags/satchels. If you are, though, there's just no advantage to carrying a battery-powered wireless charger: just go wired. It's much faster, generates minimal heat, and can top your phone off multiple times (depending on your battery pack).

Same reason why I use wired charging in my car, even though it has wireless charging available. I'd... rather not have my phone get hot to the touch from wireless charging + the sun beaming into my car, especially if wireless CarPlay is active. Wired will charge it faster and be cooler, so what's the point?
