I use my wireless stick in the car and it’s great. It’s plugged into an aux power socket, the power off on my stick is set to ‘never’ so as long as I use the car every couple of days the stick is charged.
However if I don’t and it goes flat, the next time I start the car the stick charges, but of course it’s in its off state and I have to remember to turn it back on. It would be good when it goes flat it remembers if it was switched on or off.
This means as soon as power reaches the device it would power up and it could be used straight away.
anyway great product.
