Electricity isn't a fuel.

Reactionless typically means that it does not expell mass which it claims to not do.

Actually electricity is fuel. Electrons have mass. If it doesn't expell electrons and is self-contained, we will have to wait for their explanation of exactly how it works.

It's claimed not to expel anything, including electrons. IIRC, it's based on some theories of quantized inertia, and apparently that can be harnessed somehow to create a reaction less drive. I'm skeptical, but I say, go for it if you think it will work.

It can’t just expel electrons as that would build up a charge - whatever it is, it also has to be charge neutral.

You're assuming it has nothing to interact with. Maybe it uses the solar wind somehow. Plenty of charged particles in the solar wind. Maybe it can push against the Earth's magnetic field.
