This article gives Sony Cube speaker charging instructions. Recharge this speaker easily through the micro USB DC power input port, on the back of the unit, shown in the pictures below. Note that you can still play your cube while juicing it up, without affecting the replenish time too much, especially when you use a higher-current USB charger.
Sony Cube Speaker Charging Instructions Summary
First, Sony includes a suitable USB-A to micro USB charger cord with the speaker. But you must provide a strong enough AC or car supply with a USB-A female connector, to plug that lead into. This particular speaker needs around 7.5 watts (5 volts at 1500 milliamps) for the shortest charge time of three (3) hours. Note that using a charger that offers more current than this will not cut the charging time by much.
Moving on then, once you choose the charger you will use, plug it into a “live” AC outlet.
Then after four hours, the cube finishes charging. So it’s ready to play once more for up to twelve (12) hours before needing another charge.
Sony Cube Speaker Charging Instructions, Step by Step
1. Choose a Sufficient Size AC or Car Adapter
As we said above, the power adapter you use should provide 5 volts and at least 1.5 amps (7.5 watts). So here, we use the Key Power model HDD15-3-PD USB power delivery system along with a thick-enough micro USB supply cable. Note that you may also charge the cube from a PC USB port. To make sure that will work though, check your PC specs to be sure that its ports provide enough power to fully charge the speaker.
2. Find the Micro USB Charge Port on the X11
Find the DC input port for charging on the back of the Sony cube speaker, just to the right of the AUDIO IN port, as we see in the next picture.

3. Power OFF the Speaker to Continue with Sony Cube Speaker Charging Instructions
Note that the speaker still charges when powered ON. But depending on how much extra juice your power supply dishes out, the speaker might recharge faster when it’s not playing. It will certainly charge faster when you’re not listening at louder volumes.
4. Plug the Micro USB Cord into the Speaker
Then, plug the matching end of your charging cable into the DC input micro USB port on the cube, as we see in the next photo.

5. Plug the Other End of the USB Cable into your Charger
If the supply you use has a removable wire, then be sure to connect the matching end of the USB power cable to the AC or car adapter you have.
6. Plug the USB Adapter into a Working Wall Receptacle to Continue with Sony Cube Speaker Charging Instructions
Now that we connected the speaker and our adapter, we then plug the mains end of the supply box into a working AC outlet, as we show next. In this example, we connect ours to a GE surge protecting power strip.

The CHARGE lamp on the cube then lights up solid orange, as we see next.

7. Let the Speaker Continue Charging Until the CHARGE Light Goes Dark
Full battery recharging finishes when the CHARGE lamp turns off, as shown next.

8. Unplug the Micro USB Charging Cable from the Speaker
9. Done with Sony Cube Speaker Charging Instructions !
We have now fully charged our cube speaker.
Finally, repeat this charging every (up to) twelve hours of play, to keep the battery in top condition for at least a few years to come.
