Use Your DeWalt Power Tools Battery to Make Coffee!

I’ve been a Keurig brewer owner for more than twenty-five years. I’ve been a DeWalt tool owner for at least twenty years. Before I downsized to apartment life in 2021, I owned twenty-five DeWalt tools and accessories for their 20V product line. I still have more than a dozen – nailers, drills, saws, sander, grinder, oscillating tool, flashlights, and vacuum, along with 11 batteries to keep everything going.

After my first hurricane in Florida, the one thing I missed more than anything was a simple cup of coffee. My neighbor and I tried with his small generator, though it didn’t work out all that well. Since then, I’ve been searching for a solution. Last year, when I lost power for most of the day, I was back searching after power was restored. How I wished DeWalt would add a coffee maker to their catalog of nearly fifty tools and accessories, They make radios, refrigerators, most everything. Why not a coffee maker? Up until a few months ago, the only real option was a Makita K-Cup machine that works with their tool batteries. Machine – $169. Batteries – $89 and up. One or two cups per battery. A huge investment with batteries I won’t use for anything else.

When this most recent hurricane came knocking, I started searching again. I found a rechargeable espresso machine that could make 3 or 4 small cups of espresso on a charge using Nespresso capsules. Not much help. Then I found this. Mellif is a company that makes a variety of accessories for cordless power tool battery systems. They have a half-dozen for the DeWalt line, including a Keurig Coffee Maker. It was first offered in May of this year. Perfect timing. Awesome!!!!!

I ordered it Monday for a Wednesday delivery, knowing if this hurricane changed course, I’d probably be without my beloved coffee… again. But all we got was drizzle today, and mail delivery. The machine works fine, though the instructions suck. I’ll make that known in my product review. It comes with an eight-page manual, mostly covering safety information – with three “blank” pages in the back. Plenty of space for basic operational instructions and troubleshooting tips. Like, why is the light flashing red? Fortunately, after reading reviews and some other details on the Amazon page, I was able to figure things out before putting it back in the box for return.

It brews a six-ounce tasty cup of steaming hot coffee per cycle. I put a Dunkin Dark Roast to the test, and I wasn’t disappointed. Running the second brew with the same K-Cup was weak, though that’s because the first couple ounces out of a Keurig pod are like intense espresso – very strong. The rest is just light brown hot water. It comes with a filter cup, so you can add your own ground coffee. It’s easy to set up and use the machine, once you know its quirks. You MUST wait at least five minutes between brews, or that damn button will flash red indicating that it’s overheated. Start over. So, drink your 6oz. of Java slowly. A brew cycle takes four minutes from start to finish. It does eat the battery, which I expected. That’s no surprise. Generating heat uses a lot of energy. I got two brews from my 4.0Ah battery and likely would have gotten three. I tried one of my small 2.0Ah batteries and got a full brew with the battery gauge going from 3 to 1 bar. Likely not enough juice for two brews. With my 11 batteries, I estimate about 18 potential brew cycles. Way more than enough for a one or two-day power outage. At $69 I’m satisfied. Another problem was solved.

If you have DeWalt tools, this is a great accessory for power outages, camping, pond hockey, or traveling anywhere without the benefit of electricity or Starbucks. It even includes a carry bag.
