I haven't run it up to the rated 2000W yet, mostly because I don't have enough battery behind it to supply what it needs to get there. But it's worked fine at 1100W, so it will run a crock pot, coffeemaker or tiny grill (panini maker). It will run any reasonable amount of lighting, and some power tools.
It's important to take the instructions seriously. It comes with 2 sets of cables, and both MUST be used. Internally there are two inverters in there, working in parallel, and they both need to be powered. For light loads you can hook both sets of cables to the same battery. For heavy loads you should generally connect each set to its own battery. Useful math: if you want to run a 1200w 120v appliance on this with a 12v battery, you're asking that battery to provide over 100A. That's harder than you want to push a lithium battery. so use 2 batteries. Or a single beefy lead acid battery, but those wear out faster.
And lesson learned. If the connection to the battery isn't tight, and I mean screwing down the connections with a tool, the battery terminals will heat up from even the trivial resistance the loose connection causes. It gets hot enough to cause a burn. The clamps this unit comes with are probably ok for a lead acid battery with fat binding posts, but lithium battery often come with smaller screw terminals. Make sure the screw terminal firmly engages the bottom and side of the clamp and screw it down as tight as your hand can manage. Or else!
This unit really should come with alternate connectors for those screw terminals...
