Sony SRS XB40 Charging

The DC power input port on the Sony SRS XB40 speaker.

This piece gives a routine for charging the Sony SRS XB40 Bluetooth speaker. Do this easily through the DC power in barrel style port, shown in the pictures below. Note that you can still play your XB40 as it recharges, without raising the charging time by very much.

Sony SRS XB40 Charging: Summary

1. First, pick a powerful enough adapter, as no charger comes with this Sony Bluetooth speaker.
2. Then, plug the charger into the speaker as well as a working wall outlet.
3. Finally, after four hours or so, your XB 40 finishes recharging. So it’s ready to play once more for up to twenty-four (24) hours before needing another charge-up.

Sony SRS XB40 Charging, Step by Step

1. Choose Correct Size AC or Car Adapter

The charger you use should provide 9.5 volts at 2.5 amps (23.75 watts) for quickest results.

2. Power OFF the Unit

Note that the SRSXB40 still charges when running. But depending on how much above-and-beyond recharging headroom that your charger supplies, the speaker might charge a trifle faster when turned OFF.

3. Plug the Power Cord into the Speaker

First, open the water resistant port door.
