The Portable Coffee Maker – (Almost) Man’s Best Friend

Tools and coffee seem to go hand in hand.

However, as we move more and more to portable tools, it only makes sense than we should add a portable coffee maker to our mobile arsenal as well.

Today, we’ll take a closer look and reveal our shortlist of favorite coffee machines, practically guaranteed to satisfy even the most discriminating of coffee-loving tool slingers.

  • It is actually not very easy to find a large, rugged, portable coffee maker such as the CoffeeBoxx. There are not many currently on the market. This in itself is something to consider due to the fact that this coffee maker currently enjoys a high level of feedback from its users.
  • It uses K-Cup drink pods, a standard size for coffee makers, which makes selection and availability excellent.
  • It definitely has a tough design and appears quite comfortable alongside your other power tools, as well. Many other reviewers have noted how well it seems to handle the elements and abuse.
  • Customer service seems highly responsive and eager to help overall, which is an important factor to take into account.


  • One of the first things we noticed was the weight of this little guy. At 12 pounds dry, it’s already a bit weighty, but after water is added…well, let’s just say that it does not move very easily. Perhaps this is a good thing? Just keep this in mind if your desire is to find a multi-cup drip coffee maker to lug around.
  • Another feature of the CoffeeBoxx we would like to point out is the AC cord. At just three feet in length, it does not leave many options for locating your portable coffee machine. It is worth noting, however, that the cord is retractable rather than wound around the device, therefore this would be the main contributing factor to this spec.
  • Another consideration is related to the above, and that is the NEED of a power cord in the first place. Some other portable coffee makers–as you will see with our other reviews–are free from reliance on an AC outlet, opting instead for power sources such as Litihum Ion batteries. Again, this makes the CoffeeBoxx more conducive to work site use.
  • It takes a BIT of getting used to, as it operates a little differently than other one-cup coffee makers I have experience with. If you remove your cup when you think it’s finished, then you will inevitably have to clean up a bit afterwards.


When we see a specialty product like the Oxx CoffeeBoxx, we could write it off as an overpriced novelty, as we often do with some other devices. It would be especially easy to do so if this portable coffee machine lacked the functionality and quality that both the price and details suggest.

However, this mobile creator of coffee elixir is not simply an exorbitantly priced, one-of-a-kind novelty—it serves a specific purpose, is of good quality, tough, and reasonably priced. For those looking for a smaller and lighter portable coffee maker for just one or two people, we would recommend looking elsewhere. However, for those whose coffee applications are more work site oriented and/or in more abusive environments, we do not hesitate in recommending the CoffeeBoxx by Oxx. Besides, we have to admit that they gave it an extra level of cool by naming the sleek, black version “Special Ops Black” and giving it a nice field case. Good job!

It will brew up to three 5 ounce cups of coffee on a single charge of an 18V LXT 5.0Ah battery (sold separately). It is also compatible with Makita 18V 4.0Ah, 3.0Ah, and 2.0Ah batteries.

It’s part of Makita’s expanding 18V Lithium-Ion series, the world’s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger.

For improved tool performance and extended battery life, Makita created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.

  • First off, the portability of the Makita coffee maker is the main strength it has. Not only is it small and light—weighing in at less than four pounds WITH the battery attached—it also has the main benefit of running directly off of Makita’s 18V Lithium-Ion batteries, which are a heck of a lot easier to have around than an AC outlet! Just connect the battery and you are ready to start brewing right there—wherever you may happen to be. If you do happen to have an AC outlet, however, then you can save your battery and plug it in.
  • Interchangeability is great for those who already own or are thinking about purchasing other cordless Makita tools (such as an impact wrench, for example!). No need to hunt for a plug of course, and for those of us who already own related tools, we can easily slide off the battery and whip up a cup of Joe in under ten minutes.
  • Functionality is basic and straight-forward. No need for filters as the basket has a self-contained filtering system built-in. Another good feature—and one that even some home coffee makers do not have—is that it will automatically shut off when it detects that there is no water, thus eliminating the “boil dry.” I still remember cooking the crap out of more than one coffee pot after the levels had gotten to be too low. It’s true that the reservoir is a different thing, but the concept is similar—no dry heating and no wasted energy!
  • Faster coffee on AC. If you do have access to a wall outlet, then your coffee craving can be cured in less than half the time, at around three minutes.
  • Cost. The actual price of the coffee maker itself is amazingly low, which makes it more than a nifty, cute, or fun item to have around. For those who already have the right Makita tools with included battery and charger, the addition of a matching teal coffee maker could be just the right touch—or gift.


  • Additional cost. The first thing to remember is that, as with many cordless tools, the Makita coffee maker needs at least one (particular) charged battery to function, and that battery will also need a charger. While the coffee maker itself has a nice, low price tag, the required portable power solutions will most certainly cost quite a bit more. As always, confirm what you are actually going to get before you purchase.
  • Battery eater. While you may be thirsty for coffee, your coffee maker is hungry for power. Depending on battery type, the portable Makita coffee maker will make short work of it if you are in need of more than one cup. For example, and according to Makita’s specifications, their 5.0 ah battery will only make up to three cups. So, while the portability is great, do not expect to get a nonstop flurry of hot coffee for you and your fellow workers or campers—unless you have an AC outlet nearby for your battery charger.
  • Serving size and cup accommodation size. Each brewed cup of coffee will be five ounces, which is typically a shot glass sized portion for most American coffee drinkers—especially those busy using power tools or shooting the breeze. Considering that the maximum amount of cups that can be brewed on one large battery is three, this makes for a total of fifteen ounces of coffee on one battery charge. I am fairly certain that my dad drinks more than fifteen ounces of coffee during breakfast alone. For those who may not know, eight ounces equals one cup, so five ounces is just over half a cup. The second part of this is the cup size that the Makita machine can accommodate, which is only 3.5 inches tall. Upon putting this “consideration” here, it seems a moot point given the fact that it is unable to even fill that cup up to begin with.


For me personally, I felt that this was a bit of a sad review to make. I really wanted to be very happy with this device, given my fondness for the company and their tools—as many others are. However, unlike most of their other cordless devices, this one just does not seem to have the research and development it needs to truly be a must for most applications. The simple fact that it is highly portable and can basically be taken anywhere to provide a hot cup of java is not enough for me to be satisfied, and neither is the relatively low price. The portion sizes seem more like the ones I got out of the vending machines I tried while I visited Tokyo—but those were really cool and useful, with many options. Insult is added to that injury as one realizes that only two to three of these small cups can be brewed on a single battery—something I just cannot bring myself to accept from Makita’s reputation for technology. Still, I could accept the small cup servings if the coffee maker was able to brew up a much larger quantity on one charge.

Nevertheless, I cannot rate it much lower as it is still handy for those who could benefit from its use—for it is indeed useful in its own way, and it is, after all, a Makita.
