Reddit mentions of Travel Immersion Water Heater - Dual Voltage

Have you tried pre-heating your french press with some additional boiling water so it doesn't cool so fast? You could also wrap it in a towel, insulating foam, etc..

I haven't looked, but I assume you can find vacuum-insulated french presses.

Another possibility is one of those submersible water heaters, but it might be tricky to hold a good temperature.

• Aeropress
  
• Porlex grinder (fits inside aeropress handle)
  
• A handful of paper filters and a reusable SS filter
  
• Small scale for measuring beans (water I do by volume in the AP)
  
• Third Wave Water (Only if I'll be staying in one place for more than ~4 days because you need to buy a jug of distilled water)
  
• Immersion water heater (if I suspect I may not have an electric kettle)
  
• Good beans

I did a 100 day backpacking trip around the world with a North Face Backtrack 50. It was small enough to be a carry on. Some advice others have mentioned here, first aid kit is very important, along with copies of your passport and some passport photos just in case. You should also have photocopies of your credit cards and their 1-800 number if you're bring them along. A lock to keep your belongings safe. Travelers duct tape is also useful. They're small and doesn't take up space but very handy to have. If you'll be doing laundry yourself without a machine, a sink stopper and cloths line are useful too. Eating utensils are also useful like this immersion heater, or fold up cups etc.

Wardrobe is fine, though it's better to use synthetic fabrics for t-shirts and such since it dries faster and doesn't wrinkle like cotton does when you shove it into a bag. Also to not stand out as much as a tourist, all your cloths should also match. Greys and browns work well with everything should you decide to wear the same cloths a few days in a row. If you're paranoid about getting robbed, a money belt is also good. If you get past the dorkyness of it's wonderful. I had most my stuff in it while keeping some money in my pockets. You don't want to be whipping the belt out for every purchase. That's all I can think of at the moment. If i come up with more I'll edit this comment.

I travel with one of these. I also travel with an Immersion heater and trusty thermometer as well as hand grinder, (not sure of the model, I've had it quite a while.)

You could consider getting one of these.

stinger although what we used was home made.

Instead of a kettle, you could use an immersion heating coil like this: http://www.amazon.com/Travel-Immersion-Water-Heater-Voltage/dp/B000AXS0UE

Also, instead of hauling jugs of water from the store that has been sitting in plastic, why not just get a brita or (even better) a tiny Berkey filter?

I'm just a regular joe coming from /r/all, but I had the thought of using heat. I'm thinking either a torch set to a low flame, or a handheld electric heater like this.

Obviously potentially dangerous and destructive, but I think if you keep your eye on it and be careful, you could achieve a nice melted layer on the inside.

Edit: Thought of something else. You might be able to buff the inside smooth, like with a small felt buffing tip or a smooth metal piece of some sort in a drill. This might technically be called burnishing.

Growing up I knew somebody that had one, but only one person.

We have a kettle that goes on the stove at home. In the absence of a stove, my ma uses an immersion heater and the rest of us heathens boil water in the microwave.

If egg-boiling is on the horizon, one of these might be better: http://www.amazon.com/Travel-Immersion-Water-Heater-Voltage/dp/B000AXS0UE

found one of these at a thrift store the other day...
