Specs are up on protovapor: https://www.protovapor.com/wp-content/uploads/2018/03/DNA250ColorDatasheet.pdf

Correct on the connector. I think you mean power delivery spec USB PD 3.0 which is not the same specification as the USB spec (2.0, 3, 3.1, 3.1 Gen 2, or 3.2). All of which support USB PD 3.0... But that still wouldn't matter because the USB PD 3.0 spec defaults to 5V@2A and allows for negotiation of 12V@1.5A, 12V@3A, 20V@3A and 20V@5A- The device would have to support a PD profile at 20V/3A or 20V/5A - and 20V/5A is only supported by USB C. The only technical reason you would care about USB C vs B-Micro (assuming your cable/connector is compliant) is if your device tries to negotiate 20V/5A - everything else is just convenience i.e. not having to flip your connector over 3x or not having another type of cable..

So here we at in march still waiting for a device rumored last summer, confirmed before thanksgiving, all but promised by Christmas and now nothing but silence... Well, one thing for sure, marketing hype in the vaping world hasn't changed much in the last 9 years..... So I'm staring at this post for almost 2 weeks now and looking at "what's the big deal about USB C"? I'll take the bait.... I think a lot of you missed the point- it's not about the USB C cable/connector, it's all about USB Power Distribution ( USB PD) at higher voltages and currents - which happens to require a USB C cable/connector. Just because a device has a USB C connector doesn't mean it's capable of providing or taking advantage of USB PD. Because many of you clearly haven't read the PD spec, understand that PD is a protocol for negotiating and delivering power to/from a device. The operative word here is negotiating. Take a look at the main page of the specs for USB PD http://www.usb.org/developers/powerdelivery/ (just the cover page) Note the first bullet - "UP TO 100W charging" - Point being even if we have USB C and USB PD we would need a high power supply AND a device that is capable of accepting that power. For example G-Class SX has a USB C connector. it only works at 5V/2A..... cool i can charge my Samsung phone and my SX on the same cable but i still need 2 damn cables because it takes forever to charge...... I don't know if the SX supports PD 2.0 or not (and it doesn't matter) - I do know from the data sheet that it only supports up to 5V and 2A. Point being in this scenario USB C does nothing and a 100W USB PD charger would still deliver 5v/2A.... In this case I would agree that it's much ado about nothing. Most of us (OP most probably an exception) would welcome the ability to not have to remove/handle/carry spare LIPOs (or any other batteries) around IF we could get a rapid charge (i.e. 1/2 an hour) up to 80% of charge- in a perfect world where you could plug a 80W or 100W charger in your cigarette lighter, or carry a little i-phoneish mini-brick around with you, it could work. And then USB C (with PD) would matter. Reality check- I haven't seen any truly portable 100W USB PD chargers.. and think about that 5A fuse on your cigarette lighter (good luck getting 100W out of that).... Net:A device that can support USB PD at higher voltage and current would be a game changer for many but there's a lot of external stuff that needs to be resolved before it makes a difference. So I agree- USB C in and of itself is a nothing burger.
