Cov teeb meem uas feem ntau plague rechargeable qauv-xws li Circuit Court tsis ua hauj lwm thiab cov kua xau- tau daws tag nrho nyob rau hauv pov tseg e- luam yeeb.
3. Ntau dua E-Liquid Capacity: e-kua muaj peev xwm ntawm e- luam yeeb tuaj yeem yog tsib mus rau yim npaug ntau dua li ntawm tus qauv rechargeable, uas ua rau lub neej ntev dua rau lub cuab yeej.
4. Lub roj teeb muaj zog dua: Nrog rau cov khoom siv hluav taws xob zoo li e- luam yeeb, lub cuab yeej yuav tsum tau them tsawg kawg ib zaug rau ib daim cartridge; qhov no ua rau cov roj teeb tsis tshua muaj zog- sib npaug rau qhov xav tau rov qab rau txhua 5 txog 8 cov luam yeeb ib txwm siv.
