Bonsenkitchen Portable Touch Induction Cooktop

There might be another person looking at this for the same reason I did, to keep a stainless kettle of liquid boiling at a constant rate so the vapors can be collected and condensed. It works brilliantly for that, much better than the similar form factor resistive hob I started with that even on max would pulse on and off leading to bursts of boiling. It also stops boiling almost instantaneously if you turn it off, which is handy for this purpose. If you're looking for something to do hot pot in that's a very similar task and it's pretty much perfect for it. Beyond what I bought it for I'm pretty impressed with where induction cooking has gotten to, this thing can dump some power into a piece of metal, and does it in a more constant way than the slow pulsing on and off of almost all resistive burners. The perception I used to have of these was finicky and niche and more than anything an expensive piece of exotica for the Sharper Image type of yuppie, but now that the price has gone down and solid state switching has gotten so robust this seems like it's the best of both worlds of gas and electric in terms of the combination of power with fairly fine grained control. There are of course some physics based limitations but almost all the pots and pans I have around are either ferrous or have a ferrous induction plate despite that never being something I considered when I was buying. The only exceptions are a couple of commercial kitchen stamped aluminum sauce pans I bought from a restaurant supply. It's got a fan and sounds like a computer, but the boiling of the kettle itself is louder. Might be slightly annoying if you're doing a slow simmering hot pot in a very quiet room, but in the kitchen it doesn't bother me at all. No idea how long it will last, but based on previous experience with random "cheapest X on Amazon" mostly electronics-based products, if it works out of the box it's probably not going to die for at least a couple years. Electronics in general have gotten very reliable, even when everything is built to a price, and this thing is more or less a solid state high frequency switching power supply.
