This piece gives charging instructions for the Sony SRS XB10 extra bass wireless 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 this Bluetooth speaker while it charges.

First, pick a hefty 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.

Sony SRS XB10 Charging, Step by Step Instructions

1. Choose Rightly Sized 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 for best charging performance. So this Key Power model provides way more than enough current capacity to do the job.

2. Open the Port Cover on the XB10

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

Note that the SRS XB10 still charges when powered ON. But depending on how much above-and-beyond recharging capacity your charger delivers, The speaker might charge a little faster when turned OFF.

4. Plug the Micro USB Cord into the Mini Speaker

Then, plug the small end of your micro USB charge cable into the matching micro USB port, as seen in the next shot.

9. Fully Close the USB Port Door

Note that unless you snap the port flap securely, water may soak its USB port. And, since water and electronics generally do not mix, getting the port wet might damage the electronic components inside. So be sure to press the port door closed with enough force to fully seat it, for maximum water resistance.
