BOBOVR E3 Pro Battery Head Strap for Meta Quest 3 and Meta Quest 3S

The BOBOVR E3 Pro Battery Strap for Meta Quest 3 and Meta Quest 3S is a head-mounted accessory designed to extend the runtime and improve the weight balance of compatible Meta VR headsets. It integrates a 10,000 mAh B100 lithium-ion battery into the rear of the strap. This power unit supports 22.5 W fast charging to reduce downtime between sessions. A magnetic attachment mechanism allows the battery to be detached for convenient replacement. Ergonomic construction with adjustable straps and a rear dial helps distribute the headset's weight more evenly, reducing facial pressure during extended gaming, fitness, simulation, and media sessions.

Weighing 445 g, the strap acts as a counterweight to the front-mounted display. Its low-profile rear section is shaped to stay comfortable when the user is lying down. The package includes the E3 Pro strap, one B100 battery, a USB-C to USB-C cable for power delivery, and honeycomb padding for added cushioning. No AC adapter is included, so a separate USB-C wall charger is required to recharge the battery. The rear weight distribution keeps the headset balanced during active movement without shifting.
