I just want to know if my JetPack needs to be powered on to use it to charge another device, or will it charge even if it's turned off?
Also, will I be given any indication that it's charging another device? e.g., some icon on the screen lights up or changes pattern or something?
Good concerns Joeysgirl, I can understand wanting to know all of the detailed functions of the device. Yes, you will need to power on the device to charge another device. I have provided the following link to review the indicators for your device.
