Review on 🔥 HEATIAC Travel Immersion Heater: Dual Voltage Electric Boiler for Water, Coffee, Tea, Soup - On/Off Switch, 300-1300W, 110-240V by Andrew Frison

I just stayed at a hotel that didn't have a coffee maker. I bought this device to easily have my morning coffee without leaving the room. During the first two uses, I watched the device (and kept it in a coffee mug) until it got hot. It worked well, but I didn't like standing and holding the unit while it heated the water. I used the disposable paper cups provided by the hotel so I felt uncomfortable leaving them unattended. After a few uses, I found that the heater "does its job" while I was away. The paper cup held up well on the heater and I was able to get the water even hotter (I really love hot coffee). I am very happy with this purchase and plan to take it with me on future vacations where a coffee maker is not available. I don't recommend taking a cruise ship as they most likely confiscate such electrical equipment (to prevent fires).
