Love my Keurig for my morning cup of coffee. I used to have a Tassimo - threw it away or gave it away - can't remember - their coffee flavors were terrible. I own an espresso machine at home. I fire it up when I want a great cup of coffee but it takes forever and is worth waiting for when time permits. Keurig coffee is sealed in their k-cups right after grinding. I find it to be fresher tasting than almost every other convenient method of making a fast coffee. You need to find the right flavors of Keurig coffee if you want something that doesn't taste like swill (Tim's or McD's). I always buy the Timothy's coffee for my Keurig in the bold varieties. Midnight Magic, Parisian Nights, Rainforest Expresso, Etc. I find they hit the spot perfect whenever I want a cup of coffee that doesn't taste like dishwater.

On a humid day, when it's raining, I'm not so tempted to go outside for coffee. As far as time the Aeropress takes - challenge accepted. I don't know how fast you can boil water and then let it cool for about a minute (according to my instructions with my Aeropress) but I'll bet I have a coffee for me and the wife in the same amount of time.

AGREED!

AGREED! Everybody has their own idea of what good coffee is. I have been all over the world and had everything from a Turkish coffee that had the consistency of roofing tar but was absolutely wonderful to coffee that I swear tasted like boiled shoe laces. (I actually believe that shoelaces would have tasted better). I drank it anyway to be polite as it most likely cost the family a day's wages but I more than made it for it.


At the outset of my original post I knew I'd get a lot of opinions and counterpoints to my method.

To quote myself:

All I am presenting here is my solution to making good coffee in the morning without firing up my propane stove, or having a huge battery bank and a huge voltage inverter and enough solar panels to light up a house.

I have a small trailer, as many of us do. I don't rely on shore power for anything although it is nice to have. I don't have a microwave or Television or built in heating system or A/C. The only conveniences I have is a 3 way fridge, a 2 burner stove and some led lighting. I just wanted to make coffee without having to 'heat up the trailer' or use stove top space needed for cooking, or adding another deep cycle battery and huge inverter just for a convenient way to make coffee - THAT IS ALL!

I hope my post just shows that there are easy ways to make 'decent' quick coffee.

Cheers
Stef


Sidenote - tried my inverter hooked to my Rav4 battery without engine running. Made 8 cups of hot water with the Keurig and the vehicle started without hesitation. My battery is 2 years old. This is just for info purposes in case someone doesn't have a battery on their trailer.

a 1200 watt electric coffee pot run off an inverter will draw about 100 amps out of a 12V battery (ignoring efficiency). if its just for a few minutes, thats OK... my Bonavita home coffee maker is 1500 watts, so thats even more juice from the battery, about 150 amps if the inverter is 85% efficient....

If your RV battery is of the marine/rv type, its probably OK to draw that sort of current off it for a few minutes. if its a true deep cycle, 150A is rather higher than you really should draw even for a short period. absolutely, that inverter should be on the shortest practical really heavy gauge wiring, like 0 or even 00 gauge, and DIRECTLY attached to the battery. its much easier to use a 120V extension cord, than try and run the DC any distance.

And that is why, as stated at the start of this thread, I bought a 700 watt Keurig coffee maker to avoid all the heavy gauge wiring and hookups.

700W at 85% conversion efficiency is still like 70A, you probably should be using 4 gauge from the inverter to the battery and keep it to no more than a few feet of wiring. 700W will take just about exactly twice as long to boil the same amount of water as 1400W.

I can't tell you how happy I've been since the invention of fire.

I would worry that the battery voltage might affect the taste of the coffee.

I'm just using the wiring the inverter with the supplied 8 gauge clip on wiring it came with. Another one of my original goals was to keep this simple. I would go with heavier gauge if I was camping for more than a few weeks total a year and I was going to mount the inverter in a more permanent manner. Right now I'm happy with just clipping on to the battery and running the extension cord inside for morning coffee. The 'extension cord' will become more permanent to bring the 110v inside but the inverter will just be put near the battery where I can keep it dry and of course 'cool'. I will store the inverter in the trailer closet when not being used or towing.

As we all know, addiction in the US is at record levels. Opioid , nicotine, caffeine addiction are all well known issues, and now we must add to that list, Keurig Addiction. Fortunately, people do not rob and steal to feed a Keurig Addiction like they do a heroin addiction (for example), and the risks of manufacturering are somewhat less than running a methamphetamine lab.

In fact for campers, Keurig addiction seems to cause no more compulsive and obsessive behavior other than going to the trouble of purchasing and transporting the needed equipment (“the works”), going outside in any kind of weather and making electrical connections to a box full of acid that sometimes vents explosive gas (also called a battery), running an extension cord to the actual Keurig machine, and monitoring the battery and recharging it as needed. The addiction does however produce a waste product, specifically little plastic cups that are a concern to many environmentalists.

How quickly one becomes addicted to Keurig coffee is not well known, but the best advice might be to never take that first hit.

--------------

Hopefully my above attempt at humor will be appreciated. I’m only on my first cup of (non-Keurig) coffee so I might have missed the mark, humor-wise. I’m happy to see that Stefan is able to enjoy good coffee, but I for one will stick with using shore power or the propane stove.

I love posts like this. It's like asking for directions, everyone seems to have a different favorite way of getting there, and it starts a heck of a conversation every time.

We use a Bunn brand Keurig cup machine at home (hotter water, stainless steel boiler), and an Aeropress in our trailer.

We boil water in an electric pot when hooked up, and stovetop in a cast iron pot when not hooked up.

Morning coffee is an important morning ritual, and an important part of a balanced breakfast.

Forget it already addicted to my Keurig so much so that that if the batteries dead and there’s no shore power I can always pull out the generator which I bring with me just for that reason or maybe I need an intervention !

You aren't alone. Search Keurig Inventor regrets invention, and you may get:
"Keurig Green Mountain bought and produces Sylvan’s invention. The company made $4.7 billion in revenue in 2014. The company even has plans to expand the empire to cold beverages, including Coca-Cola products. But as The Atlantic reported 13 years later, the inventor of K-Cups regrets ever dreaming up his invention."

My understanding is that his regret is based on the cups containg multiple plastics that don't break down or recycle easily. I hear they are working on the problem.

....and now that the inverter is installed, we had coffee at a rest stop on this trip and heated the water in the electric pot with no problem. Quick and easy.
