Document: Before I purchase Bose's speaker, I bought Logitech Bluetooth Wireless Speaker, but it was NOT working great. Making lots of static sounds, and have to shut off bluetooth on iPhones and MacBook if I want to connect to iPod. So, I decided to buy Bose SoundLink I. We love this so much that decided to purchase another one, Bose SoundLink Bluetooth Mobile Speaker II - Nylon. Second version is great, just like the first one.

But now that I know that, I make sure to charge it before going mobile. Of course, a car charger is another option. That aside...highly recommended.
I've used an earlier version of this speaker at work and was happy to get this for use at home. We use this speaker to play music on our deck off a laptop or tablet.I have a couple other speaker set-ups and this is my favorite because of the rechargable battery. We leave it plugged in the kitchen and take it out for time on the deck.
I use it every day with Pandora and my IPhone and wouldn't think of traveling with out it, I tell you it makes my hotel time away from home so much more tolerable and enjoyable. Glad I got the newest version because it sounds so much better that the  cheaper older versions I listened to at SAMs and Costco
The short version:  the soundlink shows as paired with my  macbook pro and macbook air, but doesn't play sound. I have to uninstall and reinstall it in the bluetooth menu every time I want to use it. Firmware upgrade doesn't work.Long version:  I'm a big Bose fan. I bought the original soundlink and loved it, even though it was fussy with connecting to the various apple computers we had in the house. When the new version came out I figured maybe it would be better.
I purchased this for my husband about 8 months ago, and we use it all of the time. We typically sync our iPad to it and play Pandora, and the sound is great. It holds charge for about 3 to 4 hours before it needs to be plugged in. It's also fun to have around so that friends can sync their devices as well.

Answer: This unit comes with a power converter/adapter which produces the 17 volts necessary to run the unit.  The adapter shows an input range from 110-240, but the plug is standard american.  So, while I believe it will charge anywhere, you might need a plug adapter if used in a country where the outlet plug is not compatible with a standard american two-prong wall plug.  I hope this helps
