Coffee maker off inverter and battery in a truck camper

[jaycocreek]

We all like our coffee and a recent post about using a coffee maker and an inverter with 100 AH battery got some negative opinions about if it even would work.

So I did the test with a 1002 Watt hour battery and a 1000 watt pure sine wave inverter..This battery has less watt hours than a 100 AH battery..The Jackery has 1002 watt hours and a 100 AH battery has 1200 watt hours.

This is the new coffee pot I bought to use in my TC..Mr. Coffee 5-Cup Programmable Coffee Maker, 25 oz. Mini Brew, Brew Now or Later, Black..So here it goes!

I charged big Jack to 100% for the test..



I plugged in the pot and took the reading on how many watts it was pulling..539 watts and it never went over that at any time..



6 minutes later I had four cups of hot coffee made and it only used 6% of the 1002 watt hour battery..



And the clock on the coffee machine shows the time it took to brew up a pot..



I hope this helps someone who like me,likes a hot pot of coffee out of a coffee maker..No generator required with an Inverter and a good battery..

Next test is with a 3qt Instapot off the same setup..Don't take me wrong,I like my little generators but sometimes there a pain and noisy pulling a big load for there rating.

Pure awesomeness!

OK now run the furnace and lights a few days in low temperatures, charge to 80% in the evening and see how all this performs in the morning. Yes it might still work and yet the battery will be a bit stressed and you are starting the generator as soon as overnight quiet hours expire. That is fine in a pinch but every day? I recommend 2 batteries.

I love my coffee but have absolutely no interest in an electric coffee making when traveling. I use a Melitta filter system with a regular paper conical filter. Just boil water and pour it into the funnel. The funnel has a small opening so the coffee brews slowly.

Another option mentioned is a French press. They leave a lot of sediment in the coffee and are messy to clean.

Thanks for taking the time to do the test and report your finding. I'm nor my DW are coffee drinker, maybe 5 cups over 50+ years but my mother was like you so can appreciate someone needing a cup.

596 watts for 6 minutes assuming 90% inverter efficient equates to 5.8AH. (596 / 12.0 * 6 / 60 / 0.90 ). Assuming a battery can handle the 50 amp hour load (596 / 12.0 ) no reason it won't handle it for a short duration. I do think the battery holding 12V is a bit conservative with a 50A load, imagine it would be closer to 11.5V which would make a little difference but not much.

I think the biggest problem is folks don't have the inverter 12V wiring heavy enough for the length of the wire. They also don't have a good battery monitor that tells the A/HR capacity left in the battery and the A draw/charge.

I'm glad I told that poster that a lithium could quite possibly do it.

You should try this with a acid battery. Nobody is going to have a Jackery.

Wife and I just finished a two day maiden voyage and used a Coleman coffee maker sat on the propane stove. It took over 15 minutes to brew two cups. It seemed forever to brew.

Priceless..:B

And so true for some..

Interesting that the mini pot uses so little power. I guess all of the power usage charts need to be updated. 😄 I usually boil water and then use a pour through filter. That works for me since I rarely drink more than one cup in the AM.

I was on live chat with Mr Coffee trying to find out the watts this coffee maker used and there response was,about 700 like the other smaller coffee makers but this one is so new,they didn't know for sure..I went ahead and bought it..$17 from Walmart and glad i did.

I'll bet if you hooked up alot of appliances to a watt meter,one would be surprised.

Thousand dollar battery...a Jackery...to brew a cup of coffee. Gee whiz! Why didn’t I think of that? How do you recharge the Jackery? Oh, that’s right it’s a “solar generator.”

Tbey also make propane, and cooktop cofee makers, or you can just do a cowboy brew. Up to you. But i agree, i need cofee.

I just boil water on my propane stove and use a French press. Fresh coffee with zero electricity. No generator and one less electronic device to go crazy on me. I like things simple.
