You might want to get a stove like this. I have a similar one and it holds a wok just fine. https://www.amazon.co.uk/POWER-plus-8048-Portable-Stove/dp/B000RHV3MU
The burner isn't as powerful as the one you showed, but you can get the same type of butane stove with more powerful burners (up to 4.3 kw). But they cost more.
something like this, can make tea plus infinite other foods and is way easier than an electric setup in the van.
