Question: how do you charge it
Document: did not work when I got it and it is not loud enough for a motorcycle would not even charge
i really like this works great and battery holds a good charge not like the last 2 different kind i had
to northern Wi. I had it going constantly (3 days & nights at lo volume - no place to charge it) as it was my only form of entertainment.
DOSE NOT HOLD A Charge it is useless mp 220 the 707 is much better , sorry i got the 220.don't get it.The 220.
A fabulous MP3 player at a very reasonable price. I love the sound quality and the 15 hours of play time you get from a single charge!
i've purchased the 4GB versions of these in the past and have been really content with them. but this 8GB version, i have to charge it every night, even after only using it for about an hour during the day. maybe i just got a lemon. not sure.
Ordered this as a gift and imagine my embarrassment when it would not turn on. Tried resetting it. Charged it overnight in hopes that it was just lacking charge - nothing. It is not recognized by the PC nor does it shows any signs of life. Now I have to return this and look for something better.
My only complaint is it doesn't hold a charge indefinitely when it's not in use. I charge it, put it in a drawer and expect it to still be fully charged a couple of weeks later, but it often drains itself. Then again, I do have 4 kids, so it could just as easily be them playing with it as the battery itself. (Eclipse brand, 4GB, [...])
As soon as I unplugged it however, it turned off, and was never able to turn on again. I can say this, the design on the screen in that brief moment when it was on it looked nice. It was pixelated, but nice.I'd give this 0/5 stars if that were possible, purely on the fact that it couldn't charge or turn on.
I'm not sure how to review this product, since it never turned on long enough for me to enjoy anything. I've tried everything to charge it, and nothing worked.I have yet to contact the seller to see if they can accommodate me, or at least give me a full refund.There was a moment when it flashed on during the 50th time I tried charging it.
Answer: Just plug it in your computer
