    Are there any problems with charging the Mavic battery with the normal AC charger plugged into a DC/AC inverter (the kind you plug into a car cigarette lighter)?

    I've used a pure sine wave inverter to charge my Phantom 4 batteries. No problems encountered.

    It can't really do any damage. The charger will draw what it needs, if that's not enough it will just be a slow charge. A small 400W inverter should be plenty. I also use a sine wave but it's not necessary.

    Given that the charger is only around 50 watts, wouldn't a 100 watt inverter be fine?

    I used a cheap 100W inverter. Worked fine.

    As long as you have the required 120 VAC, or 240, or whatever is used in your country, you're good. And as long as it is AC, it doesn't have to be sinusoidal. The first thing it hits (inside the charger), is a step-down transformer that reduced the voltage to 5, 10, 20, or whatever the load requires. The stepped down voltage is then applied to (normally) a full-wave rectifier (4 diodes) which outputs DC to the load, along with some filter capacitors to get rid of any "ripple".
