BoboVR B100 E3 Pro 10000mAh Battery Elite Strap & G3 Grip VR Accessory

SKU CH-QG3F-6A87Y MPN B100

A 10000 mAh hot-swappable battery strap with a built-in 3.5 mm audio jack and extended silicone controller grips adding 0.71 inches for Meta Quest 3 and 3S

Option Combo

  • Official Made-for-Meta certification ensures headset safety
  • 10000 mAh hot-swappable battery adds 3-4 hours playtime
  • 5 W fast charging restores power quickly
  • Built-in 3.5 mm audio jack enables wired headphones
  • G3 grip extends controller handle by .71 inches

Designed for Quest 3 and Quest 3S

The BoboVR B100 E3 Pro is a 10000mAh battery elite strap paired with G3 controller grips. It attaches to Meta Quest 3 and Quest 3S headsets to extend play time by roughly three to four hours. A built-in 3.5mm audio jack adds wired headphone support, which is especially useful for Quest 3S owners. The combo is sold as a single accessory kit for existing headset owners.

Who benefits and who does not

The kit suits players who want longer sessions, better weight balance and a wired audio option without removing the headset. It also helps users who find the stock controllers slippery or too short. Buyers who do not own a Quest 3 or Quest 3S cannot use this product. Anyone needing more than four hours of extra battery life per charge should look at higher-capacity solutions.

Battery capacity and hot-swap capability

The included B100 battery stores 10000mAh and delivers up to four additional hours of runtime. It supports hot-swapping so a second battery can be inserted without powering down the headset. Fast charging at 22.5W refills the pack quickly between sessions. This capacity figure is the primary factor in deciding whether the kit meets your play-length requirements.

Questions about this item

How long does the 10000mAh battery actually extend a Meta Quest 3 or 3S session?

The B100 battery adds roughly 3 to 4 hours of playtime, and it is hot-swappable so you can keep going without taking the headset off.

What does the 3.5mm jack on the E3 Pro strap let me do that the Quest 3S cannot do on its own?

It restores a wired headphone connection that the Quest 3S lacks, letting you plug in any 3.5mm audio device for lower-latency or private listening.

How much extra length do the G3 grips add to the Quest 3 or 3S controllers?

Each silicone grip extends the handle by 0.71 inches, giving a fuller palm fill and more secure hold during active games.
