You guys need to understand that wireless charging via a charging pad is not a replacement for regular wired charging. You don't bring it with you when you go someplace, and you don't use your phone while you charge via it. It's use case is for your home, office, or other places you frequent often where you can leave a wireless charging pad.
As I've said before, it's a place to put your phone when normally you'd just leave it on a desk or table. Say you go into your office, instead of leaving it on the desk you leave it on the charging pad on your desk, or at home at your night stand you leave it on the pad on your night stand. This way when it's not being used, it's always charging. For me I go to and from my office several times a day, and instead of having to plug and unplug a cable 10 times a day I just place it on my desk and pick it up when I leave, and it's always at 100%
