Inverters are not efficient, they use a lot of current to make 110v ac from 12v dc. It is best to use a converter that does dc to dc from 12v to whatever volt you need.
I use one for my laptop that makes 18v and one for my mount that makes 18v and one for my camera that is also 18v and they do not use as much power as a 400watt inverted that I tried to use.
You can find dc to dc converters pretty cheap on line, usually made to run laptops or other things. If needed, you replace the plug to match the device you are using.

How old is the battery? 400 watts is a lot you don't really need that big an inverter. Most laptops only use about 60 watts and the rest of your equip uses even less. WiFi dosen't make a diff. Maybe a smaller inverter would be the way to go.

At home I use a 220v/12V 2A transformer. In countryside I use spare 36Ah sealed batteries rejected from a disabled scooter we have in the family. Not full power, but every year I replace two of them. Besides of that I have enought power for several nights of observation.
