Looks like plenty of people are not interested and didn't explain why.
Speaking about myself, here's why I'm not that interested:
Power Combo (Charger + Powerbank)
One selling point of the V is that it should have one of the longest battery life among similar devices.
We don't know for certain if it would really last 10 to 12 hours yet, but if it lives to its promise, that is certainly long enough for at least 90% of my usage.
It also already has a 48Whr battery, a very large one for its size, also directly translating extra weight.
The V is actually a little bit heavier (accordingly to current estimations) than the competition.
Also let's consider powerbanks.
A typical ~16mAH or around 40 to 60Whr (not sure about the voltage) would probably fully charge the V once.
Powerbanks of this capacity likely going to weigh around 300g, which is more than a third of the V's weight.
Assuming its of contingent use, we can cut that to half, so 8mAh / 20 to 30Whr, enough to half-charge the V once (just a rough estimate, not my point here). But it would still weigh around 150g.
But if it's contingent, it would imply I'm going to carry it with me, and likely I won't be needing it.
I don't really want to carry more battery with me that isn't likely to be used.
TL;DR for the above: V has enough battery, I don't want to carry more
On the bright side, if Eve decides to make a combo powerbank, the best thing is we can get a powerbank that's guaranteed to work.
Docking Combo (Ports + Powerbank)
Ports are for connecting peripherals, usefulness depends on how many peripheral one has to connect.
For a docking combo however, since we're integrating a powerbank in it, it is somewhat expected to be portable.
Portability and extra ports (no pun intended) I my opinion doesn't work that well together - it would imply I'm carrying unnecessarily too many peripherals with me.
Super Combo (Charger + Ports + Powerbank)
It's has all the good things and bad things of the above two suggestions... So...
Please note that I'm not criticizing, I'm just expressing that for my use case, I don't need these combos
