REVIEWS

Compatible with Meta Quest 3:Reduce facial pressure: It adopts a suspended design and supports multi-point adjustment, which evenly transfers the original facial pressure of the host to the head. If you want, you can even remove the facial interface to fully enjoy the transparency of MR mode.
Power supply is more convenient: The battery pack adopts a magnetic quick-release design, and the battery can be detached and charged, which does not affect the use of VR host. Two battery packs are hot-swappable for unlimited battery life (the second battery pack needs to be purchased separately).
Reducing the weight of the head battery: We designed a dedicated battery pack B2 for the VR host, which weighs only 140g, which can balance the front and rear weights. Compared with the traditional power bank, the burden on the head is significantly reduced.
Double the battery life: The battery capacity of a single battery pack is 5200mah, adding about 1.5 hours (APP depends) of VR time.
Hassle-free Warranty: For any pre-sale or after-sales issues, an 18-month hassle-free warranty is guaranteed to feel free to contact us.

FAQ

Q： Why does my Quest 3/3S battery stop charging at 80% while I'm using it with a BOBOVR battery strap?

When you use your Quest 3 or Quest 3S while charging (On-Head), the internal system is designed to stop charging the battery at around 80% capacity for safety reasons. Here's what happens:

If your Quest starts below 80%, it will charge up to ~80% and then hold there—your BOBOVR battery (B2) will take over to power the system. For example, charging from 60% will stop at 80%, and the BOBOVR battery will slowly drain instead.
If your Quest starts above 80%, it won't charge further—the BOBOVR battery will directly power the headset while keeping your Quest's battery level steady. For instance, starting at 90% means it stays around 90%, while the BOBOVR battery drains to keep the headset running.

Note: If you're not wearing the headset, it will charge to 100% capacity.

Great choice for a comfortable and well built alternative to the basic headstrsps that comes with the Quest 3. It turns the headset from front-heavy goggles to more like a cushioned helmet that distributes the weight all around your head and allows you to flip up the lenses which is nice. The dial alone which tightens the headset makes it worth it but the model with a battery bank adds hours to your playtime. Especially if you have more than 1 battery. Overall an extremely comfy accessory to replace the stock strap.
