The Sony SRS XB21 speaker, connected and charging.
An adequate Sony XB 21 charger type, is a USB wall or auto charger adapter that delivers enough current to fully recharge this speaker in the least amount of time (around 4 hours). So be sure to use a charger that can deliver enough of the goods.
Also, this Bluetooth speaker has a micro USB charging port on the back. So if you opt to buy one of the charger options below, then be sure to also get the right cable. You’ll use this to connect the XB 21 to your charger of choice. Details follow.
Plus, the maximum current this speaker may draw is 1.5 amps for the shortest charging times. So, either use a USB-C to micro USB cord, or use a USB-A to micro USB cable if you go with one of the older USB 2.0 chargers below.
We successfully charge the XB 21 with the AC adapters below. Note that some of them feature a USB A type female jack. So, you can use one of these to connect your speaker if you wish to use the micro USB to USB-A cord that comes with this speaker. Or, if your charger only has a USB-C output port, then you’ll need a USB-C to micro USB cable, which Sony does not include.
Now, to the adapters we suggest.
This collection of chargers can charge the XB 21 at the max power that the speaker will need (around 7.5 watts). Plus none of these costs much. But as we said earlier, for some of them, you will need a USB-C to micro USB cable to connect them to the speaker.
This beefy household wall charging station delivers all the current you need for charging your XB 21. It delivers full USB 2 power on each and every one of its ten output ports. This means that you will not balloon the speaker recharging time when you charge more than one device at a time. In fact, this charging station supplies enough juice to recharge many older models in the Sony line of portable speakers. Moreover, you can charge them altogether too. Find this useful USB accessory here at Amazon.com. We also review this charging station here.
This CE Tech charging station is another decent size unit, that functions well when recharging Sony XB 21 BT speakers in the briefest time. This well built USB power hub you can buy on eBay for under thirty US dollars here. We also review this quad port charging system here.
This charger is available at Walmart.com. See that product page, here. At less than twelve dollars, this dual port AC USB wall adapter, with its folding plug prongs, is small enough to fit in any mobile device accessory travel kit. It’s also terrific when you take this Sony speaker on vacation. Why? Because this adapter has a blue night light. This makes finding your way around dark and unfamiliar bedrooms less risky. See our GE Jasco 2.1 Amp USB Charger, Y14 Review post for more details on this cheap yet practical charger.
Finally, some Sony speakers you can charge with this JBL power adapter, including the XB 21. Thus in spite of being another brand of charger, this adapter still recharges this unit very well.
See our JBL Bluetooth Speaker USB AC Charger Adapter Specs for further details.
So, we hope this short list of compatible AC USB chargers helps you choose a suitable adapter for your XB 21.
