This one is the XLUX Roffu by XVape, which is the least expensive battery-powered portable that I can recommend. The build quality and performance are both better than any other device I've tried around $150 or less. Unfortunately, this is not a great price range to be shopping in for a battery-powered portable, and I do think that the bump in performance and vapor quality with better devices. But what I like about this one is the thoughtful design of the vapor path, because it's not just a straight pipe on top of the oven and is actually designed to help cool the vapor.
