Can it be used to power TV sets?

ProductExpert6· 4 years ago
The inverter will put out 400 watts of continuous power. You would need to check the wattage requirement of your TV to determine if this inverter would run it. The amps times the volts would give you the wattage it requires.

Hello I am ask what size battery and watts does this inverter sine wave it take for to use it for 12-24 hours in a day thank you
1 answer-
ProductExpert6· 5 years ago
The recommended battery to use for the inverter is a 12 volt deep cycle battery. The more amp hour battery you have the longer the battery will last. The inverter will put out 400 continuous watts to run an appliance. The battery can be charged while you are using the inverter. The hours it can run would depend on the wattage the appliance uses and how long it runs.
