Im enjoying my new Dwarf (received just before Christmas) and playing around a lot with it.
Now I’m thinking about a question that is not urgent for me now, but would be interesting to know:
Thinking about the possibility to use the Dwarf “on the road” without access to a Power supply.
I own a portable Powerstation (Ecoflow River Pro) that is quite a nice tool for Camping etc. (its 720Wh battery can get you quite far) .
Next to an inverter supplying 230V AC, it also has a direct “12V” output using the same connector (5,5/2,1mm) as the mod power supply.
It seems like a nice feature to be able to “skip” the Dwarf’s own power supply by directly connecting the Dwarf to that Powerstation.
But there’s one problem: the PS output is handing out actually not 12V, but 13,6V DC (simulating a full car battery). This is a regulated output, so it will stay constantly at 13,6V until the battery switches off.
Would this still be within the acceptable range for operating the Dwarf?
Or should I forget about that idea and just use the “standard” way of using
Powerstation (-> internal converter) → 230V AC outlet → Dwarf Power Supply (-> internal converter to 12V DC) - > Dwarf?
Not that the second solution would be a real problem, it just seems less elegant, and of course less efficient.
Max. current is 3A, so that is not a problem.
