SMOK H Priv USB Charging?!

Hi, was just wondering if anyone has any concrete knowledge on the USB charging situation with the smok h priv? I've seen almost everywhere that it isn't recommended but will it work at all? if someone who has actually used the device could tell me that'd be great and if not does anyone know any other good 200w dual 18650 devices that DO have USB charging? preferable not the really obvious ones: cuboid, sigelei 213 etc…

Any help is appreciated, Thanks!
