These are the most common questions we receive at OXX, read on to find out more about the COFFEEBOXX. If you can’t find the answer here, let us know by emailing us at

What exactly is the COFFEEBOXX?

Our machine is a beyond rugged, single-serve coffeemaker that goes where you go. Its ultra-durable and built to handle the harshest environments, so whether you’re in the shop or the great outdoors, a perfect cup of coffee is never far away.

Why do I need a rugged coffee maker?

Today’s counter-top ­based appliances like coffee makers are made for just that ­ a clean, climate controlled counter-top space inside. The COFFEEBOXX was designed from the ground up based on portability and rugged use. With those special conditions in mind, everything had to be rethought – components needed to be reinforced, plastic needed to be UV resistant, the water tank needed to be spill proof and the entire unit had to be lightweight and compact to store. You get all that with the COFFEEBOXX.

Well, how tough is the COFFEEBOXX?

We’ve made it dust proof, water proof, and spill proof. The self-contained water tank keeps dirt out and the coffee clean. You don’t have to worry about taking it to the job site or tossing it in the back of a truck bed — it’s crush proof too. The COFFEEBOXX is made to be durable­­ not dainty.

Is the COFFEEBOXX battery powered? Or can I get a battery pack?

In designing the COFFEEBOXX, we realized that a battery power source would not be the most optimal. To heat the water to 190 degrees in less than 30 seconds and have quick brew times of 75 seconds, the COFFEEBOXX needed some more juice.

The COFFEEBOXX uses an ultra durable, 3-foot retractable power cable. It runs on standard US 120 volt plug-in power sources, pulls 1450 watts, and 60 Hz. Portable battery packs that are out in the market are usually between 18 volts to 56 volts, these don’t provide enough power or can’t hold a long enough charge. Plus, having a battery pack would double up the weight and costs, we desire to keep things as practical as possible.

I drink a lot of coffee, why did you make the COFFEEBOXX single serve?

Say goodbye to the days of wasting half a pot because it got stale, cold, or dirty from work environment dust and debris. No more spilling coffee into a mug or thermos that’ll only keep it hot for so long. With the COFFEEBOXX, you can make your coffee hot and fresh when you want it, wherever you want it. Single serve coffee pods are also perfect for brewing coffee on-the-go because they are easy to carry (unlike the traditional coffee makers that require bags or cans of pre­ground coffee, filters, scoops, and make a mess)

Bottom line: single-serve means a perfect cup in less time and with less waste.

I like the single serve idea but don't like using disposable pods. Is there an alternative?

Yes! EcoFill™ refillable pods are specifically designed for the COFFEEBOXX. You can find a 4-pack in our shop.

How big is the water tank and how many cups can I get out of one tank?

The water tank is the largest, self-sealed water reservoir in the market for coffee machines, and it holds 84.5 oz. When you choice the 8 oz cup you can get 10 cups of hot coffee or if you choice 12 oz cup you will get 7 cups!

If I have a taller cup, how can I get it to fit underneath into the COFFEEBOXX Brewing Compartment?

The COFFEEBOXX has a roomy Brewing Compartment to fit large cups, insulated mugs, and some thermoses. With the drip tray, it can accommodate a 7” tall cup. By removing the drip tray, which you can simply remove by lowering the drip tray and pulling out of its hinge sockets, it can accommodate an 8” tall cup. The area is 4” wide.

Is there a water filter that I need maintain or change?

Yes, the COFFEEBOXX uses a carbon filter that is located on the top of the Water Tank. The filter removes contaminants and impurities.

WARNING: Do not fill the water tank from a pond or stream, that needs a different type of filtration!

We suggest that you should change out your filter every three months to make sure that you get the best tasting cup of coffee! If you need additional filters they can be purchased in our shop.

How do I change my water filter?

1. Remove the Water Filter Holder Cap

2. Tap the Water Filter Holder on a hard surface until the filter can be easily removed by hand.

3. Take replacement filter and soak with clean water.

4. Insert Water Filter in Holder and place the cap back on.

5. Twist to lock tight before placing back into the Water Tank.

Do you offer any military discounts?

Does the COFFEEBOXX work with all brands of coffee pods?

How much does it weigh?

The COFFEEBOXX weighs 12 lbs when it the water tank is empty. With a full water tank it weighs 17 lbs.

What are the dimensions of the COFFEEBOXX?

It is 11″L x 9″W x 11.5″H

What are the specs on power?

The COFFEEBOXX is a 120 volt AC, 1450W appliance

Why didn’t you make the COFFEEBOXX with a battery?

It takes a lot of power to make good, hot coffee so, unfortunately, the batteries we’ve seen in the marketplace just don’t have the strength to do the trick (well, a car battery might work). The COFFEEBOXX pulls down 1450W so we recommend at least a 2000 watt generator or inverter if you go that route, but be sure to consult the manufacturer of the alternate power source before using the COFFEEBOXX. Also, make sure the power source is connected correctly and can safely supply the required power in the rugged, remote environments.

What kind of maintenance and cleaning should I do to keep the COFFEEBOXX running its best?

We recommend descaling every three months. Descaling removes calcium deposits that can build up (see instructions in the User Guide. on how to use vinegar and the proper steps. The COFFEEBOXX will remind you when it’s time. Descaling helps to ensure the best performance of your machine as well as the best tasting coffee.

Can I leave the COFFEEBOXX out in freezing temperatures?

Our engineers do not recommend this. Remember to always store the COFFEEBOXX in a dry, controlled environment. Empty the Water Tank and allow it to completely air dry prior to storage. Follow the directions for flushing the machine on page 13 of the User Guide.
