What vape is right for me?

Hi,

This is how I like to imbibe:

Before work and on my breaks

Out on the streets, in public, but down a side street, discretely

Small amounts, not getting totally wasted, just getting mildly stoned

I currently use a small pipe, the bowl is around 1 cm in diameter, pipe is 8 cms long approx.

I've no idea of the weight I'd smoke at a time, just say a pinch or three of grinded weed

I want to be able to be more discrete

Not having to use a lighter, inhaling one handed would be a big advantage

Not having any concern for the wind would make my breaks a lot more enjoyable, attempting discretion when your lighter keeps blowing out is very frustrating. There's also been times when I've watched those few little pinches of weed being caught in the vortex and blown out of the bowl, scattered, never to be burnt

I want a vape with a removable battery so I can charge it in work. I obviously can't leave a stanking vaporiser chilling at my workstation

I'd prefer to be able to just throw on a pinch and vape it, I watched a couple of reviews by a guy who insisted on wearing sunglasses through the video and he said it's better to fill the oven to the maximum. That doesn't particularly suit me, but if I have to do that, how long could I leave the oven sitting full like that? Days, weeks? Do you need to stir around the weed once in a while?

It also doesn't suit me to have to grind the weed too finely, but this seems quite vital to get bang for one's buck.

If I'm used to and prefer just smoking from a pipe, will a vaporised experience be similar?

Any thoughts on stockpiling/storing your avb? I will get little to no opportunity to use it due to my current circumstances. Might just throw it out. Any options other than eating it?

Thanks a lot for any responses.
