No - don't buy another KR808D-2
If you want to use up your cartos and keep using nice refillable cartos...
Buy KR808D-1 (LiteCigUSA.net,VaporLeaf.com at others) which is also sold in colors by Vapor4Life.com (and that's where the most prefilled cartos are)
Or if you want super-long battery charge get a PigCig instead (a fat-battery version bought elsewhere)
and with either use the D1 to D2 adapter(from LeCig) with it to finish up your Greensmoke cartos
KR808D-1 is the most supported 2-piece in the normal-price marketplace - most supported for filled cartos, blank cartos, reservoir cartos, adapters. and fat-battery longer charge models
BTW - most people here use and recommend manual batteries
