"Powering my fire tv stick off my TVs USB port"に関する回答Just purchased two fire sticks, one as a gift for my sister. Installed hers first. When trying to use the TV’s USB for power we got an error msg so we plugged the stick into the wall. When I installed the new Firestick into my 8 yr old Samsung TV we got the same msg regarding the USB for power ‘not enough power or low power’. Instead of plugging into a wall outlet I used the USB on the front of my DVR. Still got that error msg but it’s working just fine. It’ll be easy to unplug because front of DVR is easy access. Double checking power specs on that USB port once ATT can confirm for me.
