Ok so my dad is a semi truck driver who drives all over the country and recently convinced him to try vaping on my istick 50 watt and subtank mini, he liked it but he wants something smaller and easier for someone that's on the go. I told him the istick 50 with the subtank plus (since it holds 7ml) for him would be perfect. He doesn't want anything with an external battery, he wants something that would be convenient to plug and charge. I don't know what better you can get than the istick as far as what he is looking for. Does anyone have any suggestions besides the istick 30 watt? Also for tanks I think since he is a semi truck driver and constantly on the road it would be better for him to get the subtank plus or even that other tank that holds 10ml (I forget what its called but I remember it being square shaped). Also another issue is he doesn't want to deal with rebuilding and rewicking. Hope this is enough information for some suggestions. You guys helped me get my first istick 50 and subtank mini and they're both still going strong! He seems to be a fan of those "pen like vaporizers" as he calls them lol. Once again thank you guys very much and all suggestions are appreciated.
