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

Great battery life! Keeps me in Vrchat on my Quest 3 much longer! Real easy to swap out while still in game. I've got three of these and the charger that chargers three at a time. Made of sturdy plastic, but try not to drop them, or any battery. Especially didn't drop these on your keyboard, unless you wanna buy a new one as these are quite tough!

Best batterries. And works great to charge your phones. Not sure about longevity but as of now, I can say all batteries should work this way. Amazing to put batteries on headset without needing to take it off. Slips into magnetic place perfectly every time. And the chargers for these work 💯 as well.

This is a must have IMO if you want to have extended play sessions in VR. Comparing this to the old B2 battery from bobo, this is leagues better as it's actually able to maintain and charge my quest 3 instead of just prolonging the battery life. I personally have two of these and its made it to where I pretty much never have to worry about my quest dying, even for 6+ hour play sessions. The only kind of downside with them is that they do take a while to charge (around 2.5-3 hours using a 67W charger), though I'm fairly certain you could make them charge faster if you had a higher wattage charger. Overall, I would genuinely recommend picking one of these up, especially if you are someone who likes to have long play sessions. (Also make sure your bobo headstrap has the support for this battery, as it is differently shaped than the old ones. There is an upgrade kit for older headstraps that includes the new charging cradle and a battery for just 10 dollars more)

Batteries last a long time, I have extra one backup when I play oculus. But they do last about 3-4 hours charge less than 2 hours. So if you play for long periods of time, battery is very good.

Works quite well and even without the charging base's 30 watt charging (using the usb C at whatever it's set to) i can pretty much not worry about the headset. i get nearly upto 4 solid while using the other. the minor differince is the tip top of the charge so not much actuial power getting in there by that point :) As for how well it works on the headset. Quest3 can run and charge most of the time there are a few times the headset will fall down to around 95 but stays there from then on. Cons. Q3 Sometimes the headset does not keep the usb active or disables it. in case 1 the battery dosnt know it's supposed to be sending power. in case 2 the headset shuts off usb charging (Simple fix pop the bat off and drop it on again if ya dont here the noise inside the headset just unplug the usb cable and plug it back in again) Dosn't happen often. Wishes (this is more about the headstrap than the battery maby) Fowerd the Battery level to the headset.

An extra battery pack is a must! Charge it while playing and you'll have unlimited play time. It's super easy to attach and detach. When it's on the charger, it will show the progress so you know when it's almost done. And if it's done charging and still attached to the charger, the lights will shut off.

Battery failed early. After light use the battery stopped charging - at most 8 full discharge/recharge cycles. Very disappointing considering it's just an overpriced proprietary USB power bank. I'd reach out to support, but that appears to be non-existent. It's a lot of money for a USB power bank. Consider your options folks. Edit 7/5/2025: After posting my original review, the seller reached out and offered a full refund. I was wrong about the lack of support, looks like that issue was more on Amazon’s side than with them. I accepted the refund and used it to order another one of their batteries. If this one has the same issue, I will come back and update my review down. Considering how quickly they responded to criticism, and that they offered a full refund, I have to upgrade my review from 1 to 4 stars. Good customer support goes a very long way folks, its not just a battery in a box, it is also if the seller actually cares about their customer. 4 out of 5 Stars. As above, I will update this review back down to 1 star if the new battery does not perform well. If it does, then I think they earned that 5th star.

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.
