Hello, I wish I could check this for you. I saw there were bids on this so I have wrapped it for shipping. This is a good lesson for me in the future. Sorry I cannot answer this.
Strange question but I really don't know: I'm looking at getting this for someone that doesn't have internet or a computer..... Do you have to have a computer to run or charge this or listen to songs? I don't know how it works...
It charges from a usb port. These are always found on computers. However here are your other options, some cable boxes, TV's, Video gaming systems & cars have them built in. Also there are inexpensive adapters for car lighters, even Walgreen's sell them for $5.00. Hope this was helpful to you, thanks for asking.
