BOBOVR B100 Battery Pack for S3 Pro Replacement 10000mAh Hot-Swap Battery Accessories, Magnetic Connectors, Double Battery Power

Excellent!!!!

I've had two of these, and I don't know which this one is. The battery itself works well and gives an extra hour and a half to 2 hours using Virtual Desktop. But the second one arrived having been opened before and damaged, so it was returned.

A very good battery pack ,Bought 2 keeps the Meta P3 headset running for many hours,1 in 1 charging.

Best out there at the moment.

This battery is perfect if you buy 3 batteries and the charging station. They last so long my Son could play perpetually.

Better than the Quest 3's built in battery, that's for sure. I have 4 of these now. The 2 that came with my 2 S3 straps and I bought 2 of these here as spares. Kind of necessary if you own an S3 strap. lol I mean no other battery will fit the S3. Thankfully though these happen to be a pretty damn good battery. Adds hours of play time to your Quest 3. If you do short play sessions around 2 to 4 hours, a single battery might be enough, but if you plan on playing all day long and want to be untethered, you're gonna want to grab some of these. Only complaint is they're a bit pricey compared to similarly rated USB power banks. But seeing as they're designed for a specific strap in a currently very niche market, that's to be expected. (I have Romoss power banks that last longer and cost less, but they don't fit on an S3 strap now do they? lol) Thankfully they do seem to be well made and feel like a premium product. If you have more than 2 of these you may want to also get a BOBOVR BD3 charging dock also.

Perfect batteries to extend play time on your device. Evens out the weight distribution, and your headset will not drain while a battery is on, uses the battery first. Strong magnets, seats on the charger and headset perfectly. Zero complaints with BoboVR stuff that I have purchased so far (S3 Pro, charger and 3 batteries) Now they need to make a premium over ear/floating speakers to finish their headset off. As far as I know, they can NOT be used as a battery bank to charge your phone or other devices, though I could be wrong. Never purchased them for that, so I have no reason to test that.

Ok

amazing :o

Pros: • Longer VR sessions made easy. The B100 delivers up to 3–4 hours of extra playtime per pack, letting you swap batteries mid-session for uninterrupted immersion.  • More capacity, minimal extra weight. Compared to the older B2 pack, this one nearly doubles capacity (10000 mAh vs. 5200 mAh) while adding just ~28% more weight.  • Smart and safe design. With high-precision Texas Instruments BMS chips, it offers accurate battery-level readings (1–100% via 4 LEDs), plus built-in temperature sensors and protection features for both performance and safety.  • Efficient power and heat management. The updated high-voltage design improves energy conversion, delivers higher output, and reduces overall heat compared to prior generation packs.  Cons: • Compatibility limitations. It’s only compatible with the S3 Pro strap (and not with older M1/M2/M3 series headbands unless using the separate B100U upgrade kit).  Verdict: If you’re using the S3 Pro with your Quest 3, this battery pack is a no-brainer—offering significantly more playtime, smart safety features, and minimal added weight. It’s a truly essential accessory for longer VR sessions without the hassle of charging downtime.
