Most electronics should take it ok. The stuff you have to worry about is that which puts a large capacitive or inductive load on the unit. Motors and fluorescent lights with non-electronic ballasts fall in this category. Effects I would watch out for are overheating and shortened lamp or ballast life. Also, check the inverter - some should not be used with a load that is too reactive. With motors, there is also the starting current to factor in - it can be a lot more than the running current.
