I got my Chinese Induction Heater today and popped the top to allow a look inside. I also did a video which I will upload as soon as it's done converting and uploading to YT. I am not one to bash the Chinese or their workmanship. I repair a lot of amplifiers and PA systems for the bands that I play in and I have seen some very nice work come from China as I have seen some very poor work come from the US and Japan (well, almost never bad Japan. LOL). Unfortunately, this heater is NOT one of those items. LMAO Pretty piss poor workmanship. Not the worse I've seen but, not great. It looks like they had to upgrade one of the chips and couldn't find one in the DIP package so the had to use an adapter and a SMD package. LOL Not sure what that chip is. I tried this with my 2018M with a stainless tip and with a Vong with a Ti tip. Both seem to work about the same. The video is the first try right out of the box with a cold cap. It took about 11 seconds to first click and about 13 seconds to the second click. The hit was awesome. The same as from my DIY heater and from a torch. Second heatup was a few seconds shorter at about 9 seconds. To dispel any doubts in anyone's mind as to whether this works with a VapCap or not, you can set you mind at ease. It works great. I did a little experimenting and, of course, it made a difference how deep you insert the VapCap. If you press it all the way too the wall, it's too deep and takes longer to click and heats the stem, same as if you held the torch in the wrong place. Not far enough into the cup and the cap clicks before it's ready. Again, same as a torch. A 10ml beaker fits perfectly into the opening and will allow me to set a fixed depth. There is a variable pot in the circuit that might also allow some tweaking. Overall, very nice and a great companion to any VapCap. For 50 bux, I think it's a great choice. Here are some pics.
