I started smoking with massive bong hits and I'll never move away from that, so I needed to find a vaporizer that was able to provide what I was looking for. I've been through a long list, all with their own pros and cons and various "best" ways to use them.

I started with the FM V5.0s, then the Grasshopper, Arizer Air, Solo 2, VapeXhale Evo, then Mighty family with the Volcano and Plenty, Arizer V-Tower, then the Fury and the Tiny Might.

For bongs, most of these suck or have shortcomings. The Grasshopper (no longer available and should honestly be avoided) was incredible and served me very well, but the company was mishandled and effectively scammed people. However, it was the pinnacle of portable bong vaporizers - seriously unparalleled and its only shortcoming for me was you'd have to reload it if you wanted more than ~2 or 3 very large dense hits (i.e. group sessions). It's too bad it's unavailable, because it really was the best ("when it worked", as the users memed).

The VapeXhale Evo, also no longer available sadly is the next best, only "second" to the Grasshopper for bong rips because it's a desktop vape and it has a heatup time. But the pros outweigh those "cons" that make it "second", easily reloadable baskets and the best convection bong rips on the market at the time. Alas, the company grew old and repurchased and rebranded until a new unit never released and they folded. The biggest loss aside is the ez-load bowls, since they are compatible with a number of devices. Anyway... it was nifty, it heated a glass element that heated the air and made it a full convection vape.

The Mighty is ok for bongs. I differentiate them via the actual glass and pressure of the bongs. Imagine a beaker bong or any bong that you hit and the smoke/vapor condenses in the glass before you carb it and get it all. The Mighty does not do that at all. The Mighty is a bubbler that you when you hit it you get some smoke/vapor - no condensing. It's not my preference, so I personally am not very satisfied with the Mighty as a bong ripper when compared to my other options.

The Volcano is just loud. It's fine, it's fun to have the bong percolate itself but, well meh. It's expensive and loud, it uses a lot of bud but it does put out a lot of vapor. The older V-Tower model is in a similar boat, it's quieter but a little less efficient than the Volcano. I use them for gatherings. The Plenty is fairly disappointing.

The Arizer portables (I have the Air 1 and Solo 2) are weaker than the Mighty through glass so not what you're looking for for bong rips.

Finally, for portables worth mentioning that leaves the Tiny Might. It's a great vaporizer, I find it fairly comparable to the Grasshopper and I'm pleased with it overall. My only shortcoming for it is that I'm constantly reloading bowls, but otherwise it's a strong consistent vaporizer.

But for you OP, I would suggest looking into Ball Vapes. I personally can't 100% recommend any particular one as I'm unfamiliar with the specifics of each and what they all entail, but as a brief overview; ball vapes are desktop vapes controlled by an e-nail PiD controller and are essentially e-nails for convection heating. It's actually just the exact concept of the VapeXhale Evo just inverted, since we are moving the heating elements to the top of the bowl (rather than it being confined).

You can build your own for about $100, but there are plenty of kits available from Cannabis Hardware or Vgoodiez (and I'm sure others, but you can't go wrong with these two.)
