I need some suggestion too. I left my Clip half a night on my laptop and it didn't charge. Maybe must connected in MTP mode to charge, or what?
It consumes 500mA current from the USB any time it is connected, but not charging all the time. Strange!

My ACER laptop shuts down its USB ports after a while of quiet. So it's probably the laptop not the Sansa Clip.

The Screen was still on, when I detached.

Do you know if it's a low-power or high-power USB port? According to the user's guide, the Clip requires a high-power port to charge.

not sure if this was meant for me to try with the wall charger or the other guy, but it doesn't charge when plug into the wall charger.

I don't think all wall chargers will necessarily work. I think the USB protocol describes an exchange of signals that a device can require in order for it to charge. A well-behaved USB host (PC or wall charger) will engage in this exchange. If it doesn't (maybe because the device for which your wall charger was originally intended doesn't either), then the USB slave (the Clip) won't charge.

I'd be surprised if not all the wall USB chargers would be a simple 5V power supply supporting 500mA current. I suppose there is not any charging circuit in them.

It's an ordinary USB 2 port. I never heard about low power or high power USB.
The USB specification is 5V 500mA. I think the user's guide means that the player need this power, so do not charge on a passive USB hub with any more USB devices connected to it.

In fact I've already charged the Clip on my laptop's USB port two times. But sometimes I left the player on the USB cable and when I removed it, the Clip didn't charge even if it was left on for hours. I can not figure out why.

Well, Sandisk has, because they mention it in the Clip's user manual. ;-) Lots of stuff on it can be found via Google, too.

Changing ports is always a good idea ... some ports just act screwy. For example, a lot of Dell Dimension PC owners are finding out that their Zunes don't sync correctly if plugged into a USB port in the front of the PC, but sync OK when plugged into a port in the back.

I think as long as it provides 5 volts output (and no more), you should be OK.

Have there been any further insights on these USB chargers? I already have the makings of an AC charger for the Clip in my junque box, but it appears some chargers don't work, and I assume this has something to do with what happens (if anything) on the USB data pins (pins 2 and 3). I had planned to just provide power and ground on pins 1 and 4, and leave the others unconnected, but it appears that may not work.

Anybody know how it's supposed to be?
