The Technica Barcelona Bluetooth speaker is compact and portable, offering great sound with a 2x 2W output. Hands free answering is enabled if you connect via Bluetooth to answer phone calls through your speaker. You can also charge your device through the handy USB connection. Compatible with any device with a 3.5mm aux in connection or Bluetooth compatibility, it has a rechargeable Lithium-pol battery built into the unit.
First off you cant charge from the USB port at the back its for charging/Powering the unit.
Just got one today from Gallions Reach store E6, Marked up at £40 but scans at £20. Very powerful for such a small unit there are cheaper units but this one has a built in mic for handsfree calling. If your like me and obsessed about scanning manuals for safe keepings than i have a link to a copy i made here: https://dl.dropbox.com/u/5724200/Technika%20SPB112%20Bluetooth%20Speaker.pdf
Update: Was £20 online now £15! Dont know if instore price has been reduced
