Eleaf has officially announced the new iStick 30W and 50W devices @ Eleafworld.com and via their Facebook pages.
No mention of what kind of output (Mean or RMS) of course. But they did confirm the Stainless Steel reinforced threads and spring-loaded 510 connections on both devices. The 30W still has the bottom USB charge port; the 50W has a side USB charge port. The 50W also has Temperature Protection, but no mention of the 30W button lock feature.
Looking good. Only time will tell about the board and the voltage delivery, but I have faith that they borrowed something from Joyetech to deliver perfection...
