Battery Operating Time
Operating time will vary depending on the charge
level of the battery, its capacity and the power level
drawn by the particular AC load, USB load, or
combination of both. With a typical vehicle battery
and a 80W load, an operating time of 4 to 5 hours or
more can be expected.
When using a vehicle battery as a power source, it is
strongly recommended to start the vehicle every hour
or two to recharge the battery before its capacity drops
too low. The EN120/180 can operate while the

occurs during starting of the engine may trigger the
inverter’s low voltage shutdown feature.
