Going wireless charging only is probably not gonna happen anytime soon. Wireless charging is significantly less efficient than wired. The difference might not matter much if you are using power from the wall*, but if you are charging off a battery bank you want as much efficiency as you can--you don't want to waste power!

*(being less efficient while charging from wall might not matter to you as an individual but consider if everybody was charging with such an inefficient means... that might add up to a lot of waste)

Wireless power banks are already a thing, and they're great because you don't have to mess around with cables. For those of you not using iPhones, they support standard Qi charging as well as faster and more efficient MagSafe charging.

I care about wireless charging efficiency as much as I care about plug-in USB charging efficiency, which is not a lot. If wireless charging is half as efficient, it's costing me a couple bucks extra per year.

For wireless power bank, the problem isn't cost but efficiency. Half transferring efficiency compared to wired means that you need double capacity power bank to charge same amount of energy. I want small and wired. Wired is also useful because power bank can be separated so I put it on pocket or bag while I have a phone on my hand.
