Since you guys are making the Riva yourself, I was wondering if you could add a couple features to the next batch - USB charging/passthrough and true 3.7V operation.
Adding a PCB with a mini-USB connector and a charging circuit would only add a couple mm to device, but it would give it a lot more functionality. Also, using the full 3.7V from the battery would provide a stronger vape. madvapes managed to add both these features to a regular 510 battery, and it's a pretty neat idea. It would be even neater on a big battery like the Riva. I know it would definitely push me over the edge to buying one. It would also further differentiate your product from similar devices like the ego.
