Just make sure that the inverter handles the same, or ideally, more than the ion battery charger draws.
For example, to charge an 18v Milwaukee fuel drill battery they recommend a 350 watt or higher inverter (so the one posted might not work for that).
I don’t know what the ion battery charger draws, but if the inverter is under-powered it could not work, trip a breaker, or charge super slow.
And (suprise, suprise) as wattage goes up, so does price. And depending on the electronics they can also get picky about “pure sine waves”.
