A:Answer Hello Keith,
Thank you for your question. What you are describing is connecting a power inverter directly to the battery in a vehicle. The XBox 1 uses 112W and depending on the TV size, it can be another 100 plus watts. AC output Battery backups use AC input. The minimal wattage of a UPS would exceed the wattage limits of the wiring for the vehicle’s power port and cause damage over time. A solution is to get a power inverter, that can connect directly to your vehicles battery, and has enough wattage to run your Xbox and TV. Thank you.
