UPDATE: Customer service was very helpful and sent me a new device, which now works.  I originally ordered the product on August 31, 2015 for a camping trip. They contacted me over 2 years later to try and make things right.  I have been getting several emails to try to fix it (fix this review) after they sent me the new one.  I really appreciate the replaced device... it just would have been great to have the initial one work when I really needed the product.
New one works.

This would not charge! It was plugged in overnight and only increased by one percent. We have up on it and haven't even been able to use it. Super disappointed

I tried to turn it on by long pressing the on/off button and nothing happened (no lights turn on).  I tried charging the battery using the provided wall charger for several hours and no lights turn on at all that would indicated the level of charge.  I also tried the provided car charger and also did not work.  The battery seemed completely discharged and unable to be charged. I own two other portable car jumper of a different brand and they work as expected!.

I received this yesterday and was so excited because of the reviews that I read.  After plugging it in to charge for hours, it still will not charge.  What an incredible disappointment.  There are no trouble shooting instructions, no way to make it work, and now I have to go through the hassle of returning and shopping again to try and get what I need.  What a pain.

I bought it and didn't work at all I tried to charge it but didn't work! It's probably a manufacturer defect! (Never got charged) I plugged it in and didn't work.

I cannot get the item to charge.  The most it has done is 25% and the directions say it will fully charge in 4 hours.  It was a gift and now my husband has no gift and I am out 60 some dollars.

Unit can't be charged, no matter what cord is used. Connector is not making contact with battery, it must be wiggled to get a charge indicator.

The unit never did work, it would not charge at all; would only play songs that were loaded when plugged into a USB port. Have contacted SouthernTelicom for techincal support.

When it arrived I was so excited. I went to power on and it wouldn't go on so I thought it had to be charged. I then plugged it into the charger , and not only did it not charge, but the insert that plugs into the speaker to charge snapped; so now it really won't charge. Never been so annoyed. It also says that it links to your Bluetooth when the speaker is off. False. It didn't do any of that.

The first one I got wouldn't charge, and thanks to Amazon not offering an exchange on this item I had to return it and pay for new shipping. I was not happy with that. Once I got the second one in it worked like a charm.

Fully charged and following all the instructions this device did not work. I sent it back and purchased a different device.

Took up to six hours to charge, and would only run for about 15 minutes. It wouldn't follow or recognize any commands.

I can't get this thing to charge.  This is my second one with the same problem. I returned the first. (Nice job with getting me the replacement, Amazon.) I try charging the unit and the blue light on top flashes, but the unit won't turn on and even after 20 hours of charging it does nothing.

Once in a while, while charging, it'll randomly turn on and you can use the menu, but after a few minutes it goes black.  I've tried charging with a USB wall adapter and PC USB port.  Same behavior.

Very disappointing after reading all the good reviews.  Creative labs support site has been no help.  They suggest pushing reset (which does nothing) or upgrading the firmware.  How do I do that on a dead player?  It needs power for the PC to recognize it.

Spend the extra $100 for an iPod.  Hours fudging with this thing to get it to charge: 10.  Hours spent enjoying it since purchase four months ago: 10.  What a huge waste of two hundred and seventy-five dollars.

Had to return this item because it would not charge.  Even spent $25 on a special charger and it still would not charge.  That was the same problem I was having with my original Kindle.

The main display switches between 12v or 6v and percent charged of the battery. The percent charged display read 80% at the 10 amps setting on this particular battery to start with. After a few minutes it read 85%. I then turned the unit off, waited about 30 seconds and turned it back on. I thought it would start charging with about an 85% charge. Instead the display reading jumped to 93% charged. A similar thing happened on two different batteries. The charger may be resetting itself accurately when turned on the second time, but don't feel comfortable leaving this unit unattended.
