If you have twin charger station, you can use the charger and cable of quest2, or the charger supporting DC5V2A-DC5V3A with the cable we provide, connect to the twin charger station and put the B2 on it for charging.
It takes about 3-3.5 hours to be full for the 5V3A charger to charge the 2 B2 of the twin charger station at the same time. With a less than 5V3A charger, it will take about 4 hours to fully charge.
If you don’t have a twin charger station, please charge the B2 separately. When charging separately, please don’t attach it to the headstrap to charge with quest2. Our B2 does not support charging with quest2 together.
If you charge B2 alone, you can use the charger and cable of quest2, or the charger supporting DC5V2A-DC5V3A with the cable we provide, connect the USB port of B2 to charge, it takes about 3 hours（the charger supporting DC5V3A） or 3 hours and 20 minutes（the charger supporting DC5V2A） to be full.
When using a twin charger station, if you encounter a situation where it cannot be charged again after reaching full charge and the indicator lights on the dock are also off, it is possible that your charger has an automatic stop charging feature when the battery is full or it may have entered a protected mode due to insufficient power. In this case, you will need to reconnect the charging cable to initiate the charging process again.
