Not necessarily . . . a MSW may work. though i did have issues with a Dewalt 24v battery charger once that just got HOT and made a funny high pitched noise (so i stopped using it).
i think the the Step mode switching power supplies (that are in most modern PSU / power supplies) can have issues with the choppy mains from MSW inverters.
but I've got laptop chargers that will run on a few of the MSW inverters i have.
The thing is the PURE / PSW inverters were previously prohibitively expensive . . . . . . so MSW was a cheap option out. (and worked with
most things)
Nowadays the PSW inverters are relatively cheap . . . and not much dearer then the MSW, and the PSW will work 100% safely with 100% of products.
most modern inverter generators run PSW now too . .
so now i would only buy a PSW for a new purchase.
im in the process of doing a writeup and vid for inverters . . . . comming soon.

the one i am using in the pic above is this one. ( i have two now, one for van and one for camping, it runs all the 240v stuff when off grid)

i also have two of these . . . worked great for camping again (TE cooler boxed and LED lights etc )

the 12v socket in the van is good for around 150W . . . it will start to get warm and will possibly blow the fuse at higher wattages. . . .
so for higher wattages i also have a collection of these to clamp onto the terminals . .

and in the above pics you can see i made up my own Anderson 50A quick disconect . . .

yes most will have a low volt shut off . . . . . but in my experience that is already too late. . . the inverter has shut down due to low voltage but its normaly around 10-11v which is to low to start the van.
i would say run the engine while charging to be safe (no flat battery) . . . or get a AUX battery setup under the seat.
or just stick with mains.
