Similarly, does the oculus link charge the quest?
If you own the official Oculus Link cable or something similar, you can also connect your Quest to your computer but choose not to run Oculus Link. This will allow you to use your Link-compatible cords to charge the Quest while running native Quest content, in a similar manner to any other USB-C cord.

It is a self-contained VR experience in a lightweight headset. But you still need an Oculus Quest 2 charging cable. An Oculus Quest 2 USB cable comes as standard with the headset, but that doesn't support the Oculus Link which requires a high-quality USB C cable capable of supporting superspeed data and power.
Can I leave my Oculus quest charging overnight?
It's fine to leave it plugged in. It's fine to leave it plugged in. For some Li chemistry the cycle life can *triple* if always charged to 90% rather than 100. The only time this isn't true is for technology so old that it wouldn't hold a charge in 2019 anyway, so you wouldn't bother trying to charge it.
