Just speaking from my experience with the Wand, it has a pair of 18650 Li-ion batteries in it, which kind of limits how small it can get (and I get the impression the Wand struggles when compared with an induction heater that works on AC wall power.) Induction heaters use a huge amount of power, so I get the feeling that limits how much it can be miniaturized.

its... basic. about as basic as it can be. I built it with about $50 worth of supplies and kind of just wanted to see if i could do it. It is way easier than using a torch, no more buying fuel for it.m Bets benefit is that I can warm it one handed and still play a game or scroll my phone or something at the same time.

The commercial ones are still really bulky, and very expensive. The one I built is def still desktop necessary, but I also would love to make myself a portable one
