for me to be honest bif the battery is swapable or not is not the problem why vaporizers are often neglected...
I had a lot of vapes and to be honest there was no vape which 100% fitted my needs... and if you read this forum and you know about VAS that is why people have VAS...
as stated before if someone will invent a vape which acts like a joint this will solve a lot of VAS and will motivate a lot of old school smoker to convert to vapes...
main problems are:
1.) you have to draw for a long time to get vapor (this is boring, looks akward, does not feel natural and it is also not very stealth.... so here it would be the goal to make a vape which behaves like a joint take a 2 to 6 sec. draw and blow out big clouds) (that is also a reason why people like catridges like ccell they much better mimic smoking a joint... ) and also getting vapor should not be a challenge and technique thing (like smoking a j.)
2.) mostly every portable vape produce hot, harsh vapor so it is often small (grasshopper for example) but you need a bubbler or so to be able to enjoy the vapor... so at the end it is not really portable...
3.) also a problem is that the taste of your herb does not last long (normally after the first draw it seems a lot of terps get stripped of... catridges for exmple every hit tastes more or less the same and good)... that was also a reason why I liked microdosing and effective vape (take one hit then load new)...
4.) if it is a portable vape it should be small discreet... fit in your pocket... and it would be great if you do not have to wait until it cools off to put it in your pocket...
5.) on demand ... take a draw put it back and lets say hit it half an hour later... do not like session vapes because they are not really efficient and cook your herb...
6.) using totally safe products for the vape... especially regarding air path vape path....
7.) cleaning: it would be nice if you could easily disassemble the vape and can put the "herbchamber" separeted from the vape in iso(bath)...
8.) easy loading of herbchamber (that is important when portable... maybe a pod sytem or so... where you can pre load capsules or so with your herb... )
9.) maybe something modular where you also could change the heating element like in the normad... so in the future you do not have to buy a whole new vape but are able to change old heating element against new... that would be also maybe ecofriendly...
@RastaBuddhaTao I like your dedication and enthusiasm....
