This piece gives charging directions for the Sony SRS XP500 karaoke Bluetooth speaker. Do this easily through the line voltage input port, behind the water resistant door at the back of the unit, as we show in the pictures below.
Note that you can still play this speaker while it charges, without increasing the recharge time much.
In summary: First, this speaker comes with a suitable cable. But the power supply adapter electronics are inside the speaker. So all you need is the “cheater” style power cable to charge this unit. Thus, there’s no external power adapter to lose. But if you do misplace the cord, then be sure to pick a thick enough replacement. This particular speaker requires 76 watts. So the cable should be able to carry at least 4 amps. But typical cables available like this one carry 6 or 7 amps. In fact, the one that comes with the speaker indicates that it can deliver 125 volts at 7 amps. So we suggest not using any cable with lower ratings on this speaker.
Next, connect the speaker end of the AC cord to the speaker and plug the other end into a working AC outlet
Then after three or so hours, the XP500 completes charging. So it’s ready to play once more for up to twenty (20) hours (best case) before needing another recharge.
Sony SRS XP500 Charging Instructions, Step by Step Directions
1. Choose Right Size AC Cord
The cheater cord you use should handle 120 volts at 7 amps. Here, we use the cord that Sony includes with this speaker. Note that the XP500 has no USB port specifically for recharging its battery. Thus to avoid damage to the speaker, do not attempt charging it through its USB output ports.
2. Open the Port Cover
Use a fingernail, dime, penny, or small screwdriver to work open the waterproof seal port cover on the back XP500. See this closed door in the next picture. Be careful not to scratch the delicate seal around the inside edge.
Prying this door open reveals the AC input charging port inside, as we see next, pointed at by the blue arrow.
3. Power OFF the Unit to Continue with Sony SRS XP500 Charging
Note that the SRSXP500 still charges while you play it. But the speaker might charge a bit faster when turned OFF.
4. Plug the AC Cable into the Speaker
Then, plug the matching end of that cord into the port, as we see in the next shot.
Warning: Only use the AC input port for charging the speaker. Do not use either of the USB-A ports, as these are for for power output only or thumb drive use. So, feeding power into these USB ports will not only fail to recharge the 500, but this could also damage the electronics inside the speaker.
5. Plug the Power Cord into a Working Wall Receptacle to Continue with How to Charge the Sony SRS XP500
Now that we connect the 500 and our cord, we then plug the mains end of the cable into a working AC outlet, as we see next. We plugged ours into a receptacle on our porch.
The CHARGE lamp then lights up solid orange on the speaker. And while no battery status gauge shows percentage of charge, this glowing lamp means that charging is indeed happening, as we see next.
6. Let the XP 500 Charge Until the CHARGE Light Goes Dark
Full battery charging is complete when the CHARGE lamp in the speaker’s top button panel shuts off, as shown next.
7. Unplug the Charging Cable from the Speaker, to Continue with Sony SRS XP500 Charging
8. Fully Close the Port Door / Cap
Note that unless you seat this cap securely, water may soak the ports behind it. And, since water and electronics generally do not work well together, getting these connectors wet might damage their sensitive innards. So be sure to press this door closed with enough force to fully seat it, for maximum moisture protection.
9. Done with Sony SRS XP500 Charging
We have finished fully charging the XP500.
Finally, repeat this recharging every twenty hours of play, or any time the speaker says, “please charge,” to keep the battery in top condition for years to come. Or if you do not use the speaker for a long time, at least top off the battery charge every six months or so.
