JSAUX Battery Pack for Meta Quest 3S/3/2, 10000mAh PD Fast Charger Battery Pack (Extra 4-6 H Playtime)

How this hanging-neck power bank fits VR use

The main goal of this battery pack is to keep you playing when your headset battery runs low, without the “brick on the back” feeling. The hanging-neck format shifts the weight to your shoulders and chest area, which some players find easier to tolerate over time, especially for longer sessions or casual play styles where you do not want a rear-mounted battery interfering with balance.

It is built around USB-C charging for VR devices like Meta Quest 3S/3/2, and it is also positioned as a general Type-C power accessory for other devices. That means it can serve double duty if you travel or want one cable and charger setup for multiple handheld electronics.

Infrared function and low-light tracking tradeoff

The included IR emitter is intended to support VR tracking in low light environments and reduce low-light warnings. The practical “gotcha” is power: the IR function uses additional power, and turning it on can significantly reduce battery runtime. The device includes guidance to long-press to turn infrared off when you do not need it.

So the best way to think about this feature is as a tool for specific conditions (lights off, night play, dark rooms) rather than something you leave enabled at all times. If you play in brighter rooms, you may prefer to keep IR off to maximize runtime.

Charging speed, compatibility, and expected runtime

This power bank supports fast charging up to 20W, with the charger designed to detect the maximum charging level the connected device supports. That matters because VR headsets can be particular about charging behavior, and matching the device’s supported charging profile can help keep sessions going efficiently.

Capacity is 10,000mAh, and the intended benefit is extra playtime of about 4 to 6 hours. However, actual runtime depends on what you play and settings, with more demanding games consuming more power. If you enable the infrared feature, power draw increases, so your “extra hours” can shrink accordingly.

Compatibility is broad for Type-C devices, including Meta Quest 3S, Meta Quest 3, Meta Quest 2, Pico 4, Pico 4 Pro, PS VR2, and HTC Vive, plus other USB-C powered devices such as phones, tablets, and handheld consoles.

Pros and cons, in plain terms

When it’s a strong pick

• You want longer Meta Quest 3S/3/2 playtime without adding a battery weight to the headset.
• You sometimes play in darker environments where low-light tracking warnings are a nuisance, and you are willing to manage IR power usage.
• You prefer a cable-and-power accessory that works for other USB-C devices too, not only one headset.

When you should look elsewhere

• You mainly play in well-lit rooms and want maximum runtime, not extra low-light tracking features.
• You are sensitive to any increase in complexity (for example, remembering when to enable or disable IR for best battery life).
• You want the most consistently documented tracking performance improvements, since review evidence around IR effectiveness is limited and mixed.

Verdict

The JSAUX 10,000mAh hanging-neck battery pack is a comfort-first way to extend VR sessions for Meta Quest 3S/3/2 users, especially if you do not want a headset rear battery setup. The infrared option is the differentiator for low-light tracking, but it is also the biggest factor affecting runtime, so treat IR like a situational feature. If your priority is “more hours with minimal fiddling,” you will likely be happiest using IR only when you actually need it.
