BOBOVR E3 Pro Battery Strap with B100 for Meta Quest 3 / 3S

The E3 Pro pulls together what the factory strap is missing most: comfort for long sessions and power that doesn't run dry after two hours. As an officially certified Made for Meta product, it guarantees full compatibility with Meta headset.

The light, aerodynamic frame lifts pressure off your face and holds the headset steady even in fast-paced games, while the flat back lets you play and watch films lying down too.

FAQ

❓ Why does my Meta Quest 3 / 3S stop charging at 80% while I use it with a BOBOVR battery strap?

When you use the Meta Quest 3 / 3S while charging (on your head), the system stops charging the internal battery at around 80% for safety. If your headset starts below 80%, it charges up to ~80% and holds there, and the BOBOVR battery (B100) takes over to power the system. If your headset starts above 80%, it won't charge further, and the BOBOVR battery powers it directly while keeping the level steady. If you're not wearing the headset, it will charge to 100%.

Manufacturer's storage and use tips

To ensure long battery life and avoid operating errors, the manufacturer recommends:

• ✅ Charge the B100 battery and the Meta Quest 3 / 3S headset separately, not at the same time.
• ✅ Use a good-quality USB-C charger and cable.
• ✅ For longer storage, keep the battery charged to 60-80%.
• ✅ Don't leave the battery on the docking station or connected to the head strap for long periods.

Following these rules significantly reduces the risk of errors and extends the battery's lifespan.
