Buy this one, which supports wireless fast charging, and is super convenient -- you'll never want to plug in a micro USB after this. You can also use the charger for it with a regular USB cable if needed and it will do fast charge with that too.

For my car I use this, which is also fast charge and is super-tiny, and it lets you charge a friend's phone too.

EDIT: Bonus items -- I travel a lot and for that I love using one similar to this little charger, which I always keep ready in my bag and can charge my whole family's devices with almost no space - even the AC prongs fold in.

And once you get really hooked on fast charging, you'll want a power bank (portable charger) that supports that too. I use this one which is pretty nice, but there are tons now in all shapes and sizes.
