Hi. I started vaping a few years ago to get away from smoking and have been using 12mg 50VG/50PG nicotine juice in an Innokin Coolfire IV TC100 quite happily, but recently I decided I should have a backup in case this device gets damaged. So I bought a Geekvape Aegis X 200W TC kit with Zeus Tank the other day, thinking it would be an upgrade, less likely to leak & yet fairly similar. The external battery aspect was an element I wasn't expecting, and I was watching videos on youtube to assess which ones to get, when I came across a box opening video by someone on the channel VPZUK, supposedly an experienced vaper, who said people should be using "0mg or 3mg nicotine at the highest" in the Aegis X. He also recommended minimum 50/50 VG. Does anyone know if this device is actually unsuitable for me to continue using 12mg juice? I was unaware devices dictated the liquid I can use. Thanks.
