The BP1 is a magnetic, hot-swappable battery pack built for the BS1 battery head strap, letting you switch packs with one hand without removing the headset. AMVR rates it at 8000mAh (28.8Wh) capacity with 20W fast charging, reaching about 80% in roughly 1 hour 15 minutes. AMVR lists over-charge, over-voltage, over-power, and over-temperature protection built into the pack. Beyond the BS1 strap, it's also usable as a general USB-C power bank for phones, tablets, or earbuds.
