OK, I will not pretend, this is the first time I heard about the existance of this high voltage DC standard. But looking at this, I assume it doesn't support that:
Just like all the other chargers I've had.
However, from the electrical point of view, it should work as long as long as it's below ~311V, am I right? Then why do they always write the frequency too? I don't know what the circuit in there looks like, but isn't there a reason why they write specific frequencies?
Anyway, it's still inefficient, although not as much as DC-AC-DC, to convert from 3.7V to 300V and back to 9V or whatever the tablet requests.
So, I'd still recommend using the RAVPower charger I linked above. It's 3 times cheaper, officially supports charging Eve V, doesn't need any extra conversion because it includes USB Power Delivery by default. And it won't fry your tablet.
