BoboVR S3 Pro Strap with Cooling

The BoboVR S3 Pro is a replacement head strap for Meta Quest 3 and Quest 3S that integrates a 10000mAh B100 battery and a built-in head air-conditioning system. It uses a power-swap architecture that separates the discharge module from the battery pack to reduce heat and improve discharge efficiency by 6 percent. The strap also adds low-battery sound reminders and accurate battery level indication.

Who This Suits and Who Should Look Elsewhere

This strap suits Quest 3 or Quest 3S owners who want longer sessions, active head cooling with 100-level fan adjustment, and a flatter rear profile for lying down. It is not for buyers who need a strap compatible with the older B2 battery system, because B2 and B100 packs cannot work interchangeably. It is also not for users who do not own a Quest 3 or Quest 3S headset.

10000mAh B100 Battery Decides Fit

The single specification that decides fit is the 10000mAh B100 battery system, which is required to power both the headset and the air-conditioning module. Capacity is up 92 percent over the 5200mAh B2 while weight rises only 28 percent, and available runtime is roughly double the previous pack. Without a B100 battery the cooling function will not operate.

Questions about this item

Should I pick the B100 battery over the older B2 for my Quest 3?

The B100 doubles usable capacity to 10000mAh while adding only 28% weight, and it powers the built-in cooling fan that the B2 cannot run.

What does the 10000mAh capacity actually deliver during a session?

The new architecture raises discharge efficiency by 6% and cuts pack heat, giving roughly twice the usable runtime of the previous 5200mAh design.

How does the strap connect to the headset and what limits it?

It replaces the stock strap on Quest 3 and Quest 3S using a direct mechanical mount; the 100-level fan and hot-swap battery both require the dedicated B100 module.
