In general it will work fine unless this charger is more than 150W because then it’s likely to have power factor correction inside. This won’t like modified/square wave and might get hot or blow up all together.

Apple printers had a reputation for dying with them, and they certainly had switching supplies.

I wouldn’t risk it. A good sine-wave inverter costs far more, but is far safer.
