incredibly inconvenient
Imagine sitting in the corner near the plug with your weird resistive heater waiting for the water to get hot. You’d probably become the laughing stock of the whole campus pretty quickly
Also, things get pretty heavy when you have a 4 hour daily railway commute. There has been times when I didn’t take a bottle of water because it hurt my back
So I’ll just stick to carrying grounds and buying hot water. It costs practically nothing compared to my current habit of buying coffee which is a huge hole in my budget






Lots of people recommended Zojirushi in this thread. Will definitely give it a try. Thanks
