Can these units be charged off of bike power while underway? I intend to play music, so that will eat the battery.
I don't mind a wire during charging; I may go for several days camping and have no access to electricity during the evening, so will not be able to plug it into the wall, as the manual seems to indicate is the only charging method.
Yes, it should work connected to the bike with a USB cable. However, you cannot charge while riding in rain as the charge socket on the main unit needs to be covered to keep the innards dry. I used an external battery (1600 mAh) in my inner pocket connected to the unit to extend the battery life on a longer ride. It gave me uninterrupted use on a 3 day (1K) tour with 8+ hours use per day without the need for a wall socket.
