Here's a simple & easily reversible mod to extend Oculus Quest's play time while also making it more comfortable to wear. By attaching a USB battery pack to the back of the Quest, you'll get more time for lightsaber dancing plus a counterweight to balance that bulky HMD strapped to your face. Lovely.
In addition to an Oculus Quest VR headset, you'll need the following items …
A 10,000mAh battery pack provides a substantial amount of extra run time, plus enough weight (~oz) that I was able to loosen the Quest side straps and not rely exclusively on clamping force to keep the Quest on my head.
This adhesive velcro-brand tape can be made from standard hook & loop material, as long as it has strong adhesive that sticks to the battery pack's textured plastic case. I had this unusually wide roll left over from another project, but only a couple of 2cm-wide strips are needed.
Hook & Loop / Velcro ties are great for tidying up wiring and more. Make sure your ties are compatible with the Heavy Duty Adhesive Tape you use. We'll need the two types to stick together in order to suspend the battery pack from the Quest.
To connect the battery pack to the Quest, you'll need a USB-A to USB-C cable or perhaps a common cable type along with an adapter. I used a basic USB micro B cable along with a micro B to USB-C adapter. We'll only need power connections, so we don't need to be too choosy.
