Why is it a shame that you dislike the "official" charger? The N4 uses the standard Qi charging protocol, so you can get pretty much any charger you want.
I've tried a bunch of Qi chargers. Samsung's official S3/S4 charger is my favorite. They cheap out and don't include a USB cable or power supply, though, so you have to buy those separately. (Anker sells one on Amazon that does include a power supply that works great with the N4. Works very poorly with the S4, though, which just goes to show you how flaky random Chinese imports can be, even if you pay $50 for them.)
