Review on 🔥 HEATIAC Large Immersion Water Heater: Portable Electric Boiler for Instant Hot Water, Coffee, Tea, Soup - 1500W, 110V with On/Off Switch by Jason Unruh

So be careful because the point you have to dive to is very high on the spool and higher than most cups or containers. = You want to heat the point just before it boils, then click and drag. = I still use it in cups that don't reach the fill line, but I stop when they're half full because the spiral just above the swirl turns visibly red and it doesn't, doesn't + Has an on/off switch, so it is already better than most you can get + heats up VERY quickly - the cord is so stupidly short you'll need an extension cord
