Is the 3 pin plug provided in a cigarette lighter port inverter (12v-220) actually grounded?

Question

I have been planning to buy a 12v car inverter, that plugs into the cigarette lighter port and puts out 220v with max 200watts, for sometime now. The one that I ordered is of brand portronics and has a 3 pin plug for charging appliances like laptop etc. I wish to charge my laptop from it but it needs an active grounding. I am skeptical whether the 3rd pin of the inverter is actually grounded or not.

Well, it may be technically “grounded” to the car but the car is on “rubber” tires so it won’t be grounded in the classic sense.
However, a laptop needing “active” grounding sounds a bit curious... I have had many and the power bricks will happily work with a 2 pin or 3 pin cable - in fact some are designed to swap out a two pin plug for a 2 metre (6 foot) 3 core cable with ground pin and it works properly with either.
