This piece covers how to charge a typical Sony Bluetooth speaker. Do this easily through the USB or barrel power in port. Any Sony speaker has one somewhere. The water resistant models have it behind a flexible sealing door, shown in the pictures below. Note that you can still play your speaker speaker as it charges, without lengthening the recharge time very much.
First, many Sony Bluetooth speaker models come with a suitable charger. So use the one that accompanies the speaker if you can, for best results. But if you lose yours, then pick a strong enough adapter. In this example, we use the Sony SRS XB43 Bluetooth speaker, and this particular model requires 15 watts (5 volts at 3 amps max).
Then, once you’ve chosen the correct charger, plug that into a working AC outlet. Finally, plug the DC end into the speaker.
Finally, after four to six hours, your speaker finishes charging. So it’s ready to play once more. The play time varies among the different speaker models. But it ranges from 10 to 24 hours roughly.
How to Charge the Sony Bluetooth Speaker
1. Choose Correctly Sized AC or Car Adapter
The charger you use should provide 5 volts and at 3 amps (15 watts). Here, we use the adapter that Sony includes with this speaker. However, a Key Power model HDD15-3-PD USB power delivery system along with a thicker USB-C cable also works well.
2. Open the Port Cover
Use a fingernail, dime, penny, or small screwdriver to work open the waterproof seal port cover on your speaker if it has this. 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.
Prying open this door exposes the charging port inside, as shown next, pointed at by the red arrow.
3. Power OFF the Unit to Continue with How to Charge the Sony Bluetooth Speaker
Note that most Sony Bluetooth speakers still charge while running. But depending on how much above-and-beyond recharging juice your power supply provides, the speaker might charge a bit faster when turned OFF.
4. Plug the DC Power Cord into the Speaker
Then, plug the matching end of a USB-C charge cable into the port, as seen in the next shot.
Warning: Only use the correct port for charging the speaker. On Sony Bluetooth speakers that have this, do not use the output port. This is for power bank function only, to power other devices. In this example, feeding external power into THIS port will not only fail to recharge the battery, but could also damage the electronics inside.
5. Plug the Other End of the Cable into your Charger Adapter
If the supply you’re using has a detachable cable, then make sure to connect the matching end of the power cable to the AC or car adapter you have. Note though that the included adapter with the XB 43 here has a permanently attached cord. So skip this step if that’s the sort of cord you’re using.
6. Plug the Power Adapter into a Working Wall Receptacle to Continue with How to Charge the Sony Bluetooth Speaker
Now that we connected the test speaker and our adapter, we then plug the mains end of the adapter into a working AC outlet, as shown next. We plugged ours into a surge protecting power strip.
The status lamp lights up solid orange on the speaker. And while no battery status gauge shows percentage of charge, the glowing lamp means that charging is underway, as shown next.
7. Let your Sony Bluetooth Speaker Charge Until the CHARGE Light Goes Out
Full battery charging is finished when the CHARGE lamp shuts off, as shown next.
8. Unplug the USB-C Charge Cable from the Unit, to Continue with How to Charge Sony Bluetooth Speaker
9. Fully Close the Port Door / Cap
Note that unless you seat the port cap securely on so equipped Sony Bluetooth speakers, water may soak the power input port. And, since water and electronics generally do not mix well together, this might damage the sensitive contacts inside it. So be sure to press this door closed with enough force to fully seat it, for maximum moisture protection.
10. Done with How to Charge a Sony Bluetooth Speaker
We have now fully charged our speaker.
Finally, repeat this recharging whenever the speaker runs dead, to keep the battery in top condition for years to come. But do not allow the battery to sit, in a deadened state for long, as this could shorten its life.
