I have one, too.
A USB A to C.
Existing chargers don't push the 3 amps that the OEM one does though.
And it's a nice idea to eliminate wear and tear of plugging in and unplugging the charger.
Better to spend a few dollars on it than have to open up the phone for a repair later.
The port is one of the parts that is most likely to break.
Although the Nexus 5x seems pretty easy to open up from teardown videos, I'd still rather avoid the situation altogether.
Not to downplay your response.
That's just my train of thought.
Haha.
