Battery head strap for Quest 3 and 3S

The BoboVR S3 Pro replaces the standard head strap on Meta Quest 3 and Quest 3S headsets. It integrates a 10000 mAh battery that supports 20 W fast charging. The design separates the discharge module from the battery pack to reduce heat and improve discharge efficiency by six percent. Two B100 batteries are included in the package.

Two hot-swappable B100 batteries

Each B100 cell provides 10000 mAh capacity, a 92 percent increase over the previous B2 cell while adding only 28 percent more weight. The higher output efficiency doubles the usable capacity compared with the older design. Low-battery sound alerts and accurate level indicators help you swap cells without interrupting a session.

Adjustable overhead bracket and 100-level fan

An adjustable height bracket lets you balance the headset front-to-back, and a flatter rear profile makes it possible to lie back on a sofa. A built-in silent forehead fan offers 100 levels of speed adjustment for active cooling during long sessions. The strap uses a power-swap mechanism so batteries can be changed without tools.

Questions about this item

How often will the B100 battery packs need replacing?

Each B100 pack holds 10000 mAh, nearly double the previous 5200 mAh cells, so you swap far less often and get roughly twice the usable runtime per charge.

What limits continuous play time on the S3 Pro?

The 20 W fast-charge rate caps how quickly a depleted pack can be topped up while the other is in use, making recharge speed the practical bottleneck.

How loud and hot does the forehead fan get during all-day sessions?

The 100-level silent fan runs at the chosen speed without audible whine, and the separated discharge module keeps the battery pack itself cool even after hours of wear.
