Hi Mavic-max
I have used this inverter ( listed below ) for 2 years or more without any issue, in ebay paste this into the search bar.
Bestek 400w Power Inverter DC 12v to 230v AC Converter With AC Outlet
What you need to ensure with inverters is their ability to generate a good "Sine Wave" approximation at the 240 Vac output socket, some cheap inverters generate a very poor sine wave , which can be a very spiky wave approximation, which can damage some equipment, especially if the charger is a multi-voltage switch mode power supply.
I'm sorry I don't know the specification of the charger you are looking at, so can't help any more than that, perhaps another OP can has used this inverter and can help more, is it a cheap device or expensive, maybe that will give a clue.
Good luck
Waylander
