Battery Relief Strap BOBOVR E3 PRO for Meta Quest 3 / 3s

BOBOVR E3 PRO is a replacement battery relief strap for Meta Quest 3 and 3S headsets that redistributes weight to reduce pressure on the face and forehead. The design includes a wide rear cushion and adjustable fastening to provide a stable, balanced fit for extended VR sessions. An integrated rear battery mount accepts the removable B100 battery to extend headset runtime while keeping the strap compact and lightweight.

Advantages

The strap shifts most of the headset weight to the back of the head and includes a soft, wide honeycomb pad for improved comfort. A built-in battery pack delivers an extra 3–4 hours of use, while 22.5 W fast charging and a magnetic hot-swap system minimize downtime. The strap also features a real-time battery level display, an integrated 3.5 mm audio jack for wired headphones, durable materials and a total weight of 445 g including the battery.
