So, I buy a USB Cigarette charger + USB sync cable for HP iPaq handhelds on clearance... and wonder if this will work with any devices that charge over USB, specifically a USB iPod (I have a first gen 5GB which suits me well for now). Model: USB-CLA Input: 12-24 Vdc Output: 5.5Vdc; 700mA From what I can tell, this is OK for the USB spec, but I'm not terrible certain on the current from this device (assuming it's a voltage supply, it should be OK). I have an iPaq, but would like to use this thing to charge a future iPod when my iPod dies on me : ( Thanks! John
