Portable device recommendations

I would go with this one: https://tinymightvape.com it's a bit expensive but well built and it ticks your boxes I think.

I like my boundless CFX, but it is pretty big and you can't replace the batteries. Seems like not a lot of them use replaceable batteries

Dynavap + induction heater with removable batteries and usbc charging like the wand. Dynavap has no batteries and you can use it with a butane torch. Some people like the ritual of a torch spinning it and stuff. Induction heater lets you heat it with electric energy. The wand IH has usbc charging (not PD) and removable batteries. Though the one I got has cheap batteries with plastic sleeves that make removing back cover hard. Pros+

can do hash/concentrate One hit extraction techniques as well as terp chasing techniques

Comes in stainless steel, titanium, wood, and glass variants.

Big bowl hyperdyn has dosing capsules.

Cons+

USA based but they do have EU store. Expect shipping to take time.

The parts are overpriced IMO when not on sale. Its good quality stuff though.

Induction heaters cost a lot unless you diy it yourself.

Not the easiest device to maintain and clean. Has orings, removable screens, and builds up reclaim inside fast. Get the B to see if its for you, good price. some people like he dv experience some dont. I like it a lot I'm a big fan of H2 dynavap and the wand IH. If you dont mind going China knockoff you can try to find an EU store that sells vaphits.

Arizer air max was my first electronic portable and I can recommend it. Its a good build quality. Its usbc (though not PD so slow charging)The stem pod system is easy to maintain and plenty of after market stems. Has removable battery and held up for over a year now. Its a good terp chasing device. However its not as powerful as a dynavap. Its a slower extraction that produces a steady light vapor for some time. Not a one hit extraction capable device. Also works better with a preheat. It can't really do hash/concentrates. Great battery life though.

Arizer extremeq. I'm not sure just how portable you need, if you want an in the pocket vape its not really what youre looking for. But if you only want an around the house easily movable thing that doesnt Need a cord well.

The arizer EQ is a desktop vape very powerful and able to do one hit extractions and concentrates. It has an excellent build quality mines over a decade old and still kicking.

Even though its marketed as a desktop vape and comes with a wall outlet cord, it is a 19-20v 3.25A DC device like a laptop, that can be powered with a portable battery pack like a car jumper pack with usbc-pd 65w. Im leaving out some details on how to exactly wire it up it for brevity but if thats something you are interested in let me know.

Pros: more powerful than any standard battery portable vape. Goes up to 500f

Gold standard build quality. Mine has lasted a decade.

More versatile. has a blower fan for filling bags or if you have weak lungs and need help drawing.

Comes with large chamber hookah hose design. Some like the hose.

Cons: Easy to pick up and move around but not pocket portable. More of an around the house vape. About as portable as a small bong.

Not specifically made to be battery powered with usbc-pd 65w but can be due to having the same power draw demands as a laptop. You need to buy some special cables and a compatable battery pack.

The default glass chamber and hookah hose aren't that great IMO. In order to truly complete the EQ you need a smaller chamber closer to the ceramic heater core and direct draw. In other words, you need after market glass from DDave to get the most out of your eq experience. I'm a big fan of his one hit extraction kit with omega wand. It essentially uses removable. basket screens as dosing capsules
