The unit will be powered/charged while connected to the laptop. I've also plugged it into a USB adapter to charge it - same principal as my iPhone. I have rarely used it without some type of power source, and then only for short periods, so no idea how long the battery will last. That said, and it may not be a good comparison, but I have a small Garmin unit that I use on my bicycle and the battery on that lasts about six hours.
