Do I even need a new inverter?

Christmas is coming, and as luck would have it, it’s brining me a 100 Watt Renogy Solar Panel RV kit with controller.

I am trying to figure out if I need an inverter but the more I read the less I know.. square wave vs sine wave for an inverter... how many watts do I really need.. I imagine my requirements being:

Camping fan (or two)
Some minor LEDs for internal tent lighting
Charging of laptops, phones and cameras
Maybe charging the battery for a dewalt drill/saw

Not much more than that to be honest

Do I need much more than the stock inverter? Should I upgrade? Not looking to replace an alternator or prepare to run six consecutive espresso machines at the same time, but I would like to meet my own needs. Suggestions? Direction? Most searched posts were just missing the stock to be 400 watt constant. Not overly useful in this scenario
