This piece covers how to charge the Sony SRS XB10 extra bass portable Bluetooth speaker. Do this easily through the USB power in port, behind the water resistant door, shown in the pictures below. Note that you can still play your XB10 while it charges.

First, pick a strong enough USB power adapter, as no charger comes with the Sony SRS XB10. Next, connect a medium to high current micro USB charge cable between the speaker and that adapter. Then, plug the charger into a working wall outlet. Then after four to five hours, your XB10 finishes charging. So it’s ready to play once more for up to sixteen (16) hours before needing another recharge.

How to Charge Sony SRS XB10: Step by Step

1. Choose Correct Size AC or Car Adapter

The charger you use should provide 5 volts and at least 0.5 amps (2.5 watts). Here, we use a Key Power model HDD15-3-PD USB power delivery system. Now as mentioned, this speaker needs 5 volts at roughly 0.5 amps to recharge fully. So the Key Power gives way more than enough current to do the job.

2. Open the Port Cover on the Sony SRS XB10 Speaker

Use a fingernail, dime, penny, or small screwdriver to work open the waterproof seal port cover on the XB10. See the closed power port door in the next picture. Be careful not to scratch the delicate seal around the inside edge of this door.
