Quick answer: The reason most functional-coffee routines fall apart outside the kitchen is equipment, not commitment. Away from your own kettle, mug, and spoon, the routine needs formats that carry their own logistics. A single-serve stick works anywhere you can find hot water and a cup, which covers most desks and most hotel rooms. A tablet format works where you cannot, which covers train platforms, boarding queues, and the middle seat. This article is the practical half of the story: what each format needs, where each one fits, and the packing mistakes that catch people out. It makes no promises about what maca or guarana will do for you. For what is actually known about each ingredient, we point you to the evidence guides instead.
Coffee drinkers rarely plan where their coffee will happen. The routine forms at home, around a specific kettle and a favourite cup, and then the workday quietly moves it: to a desk, onto a train, into a departure lounge. The habit that felt effortless in a kitchen starts depending on whatever equipment happens to be nearby.
So the useful question for coffee on the go is not "which format is best" but a plainer one: where will you be, and will there be hot water? Everything else in this guide follows from that single question.
At your desk: the stick, a kettle, and nothing else
The desk is the easiest away-from-home case because offices usually solve the hard part for you: there is a kettle or a hot-water dispenser somewhere, and you already keep a mug there. That is the complete equipment list for a stick format. CafeBank's 10g stick is prepared by emptying one stick into 150–200 ml of hot water and stirring until dissolved. The preparation on the product page is one sentence long, which is rather the point.
A few practical notes that make the desk version of the routine stick:
- Keep the sticks in the drawer, not the kitchen. A shared office kitchen is where personal coffee goes to disappear. The sticks are individually sealed foil, so a handful in a desk drawer stays fresh without any container.
- The stick is sized for carrying, not just storing. At 14.5 × 3.4 cm it is the length of a pen and about as thick as one, so it rides in a laptop-bag pocket or a shirt pocket without announcing itself.
- Make it an actual pause. If the cup happens at the keyboard, mid-email, it becomes fuel rather than a break. We wrote a whole piece on the desk coffee ritual; the short version is that the two minutes at the kettle are most of the value.
- Watch the afternoon. A drawer full of coffee makes the four o'clock cup very easy. If your afternoons regularly sag, the better fix may be upstream. Our guide to the 3 p.m. crash covers timing, lunch, and light before it covers another cup.
On the commute: when there is no cup at all
The commute is the case the stick format cannot solve. There is no kettle on a train platform, and a stick of instant coffee without hot water is just a stick of instant coffee. This is the situation the tablet format exists for.
CafeBank's Coffee Tabs are a compressed tablet format: freeze-dried Arabica coffee combined with the same two plant extracts as the 10g stick, pressed into tabs. Each flat foil sachet is 7 × 7 cm, about the footprint of a drinks coaster, and holds four tabs. It fits a coat pocket, a flat pocket of a bag, or a glove compartment, and it needs no preparation at all: the product pages describe it plainly as the format for "moments when brewing isn't an option."
The two formats are genuinely different objects, not two sizes of the same thing: one is intended for a cup, the other is not. If you are deciding which suits your week, the Tabs vs. instant coffee sticks comparison walks through the differences one by one.
One timing note for commuters specifically: an early train tends to pull the day's first coffee earlier, whether or not you wanted it then. If you are curious where your first cup naturally sits, our guide to finding your coffee chronotype is about exactly that.
Travelling: pack for the day you will actually have
A travel day is really both previous cases stacked together. Some of it looks like a desk: a hotel room with a kettle, an airport café table, a borrowed office. Some of it looks like a commute: the security queue, the gate, the flight itself. Packing for both is cheap, because both formats are small and flat.
- Hotel rooms are stick territory. Most hotel rooms have a kettle and cups; almost none have coffee you would choose on purpose. Two or three sticks tuck into a wash-bag pocket and weigh next to nothing.
- Airports and flights are Tabs territory. Queues, gates, and seats are exactly the no-hot-water, no-cup situations the tablet format is for.
- Airport security: sealed sticks are the easy case. For flights to the US, the TSA's powder rule says powder-like substances over 12 oz / 350 mL in carry-on may need additional screening. A 10 g sealed stick is a fraction of that, and a week's worth still is. Loose coffee in a large tin is the version that invites questions. Rules vary by country and airport, so check locally if you are carrying a large quantity.
- Time zones scramble caffeine timing. A cup at what feels like mid-morning may be late evening where you landed. If you count your intake at all, our guide to how much caffeine is too much is the sensible reference to travel with.
What is actually in these two formats
Both the 10g stick and the Tabs pair coffee with two plant ingredients: maca and guarana. The claims we are comfortable making about them in this article are the boring, verifiable kind: what they are and where they come from.
Maca (Lepidium meyenii) is a root cultivated in the Peruvian Andes, where it has been grown as a traditional food of the high-altitude region for over 2,000 years. Guarana (Paullinia cupana) is an Amazonian plant whose seeds have been prepared as a traditional beverage by Indigenous communities in Brazil for generations, and its seeds naturally contain caffeine, so both formats deliver caffeine from two sources: the coffee and the guarana. Those descriptions are heritage and composition, not a claim that either ingredient will do anything for you; the traditions' own uses belong to the traditions. What the modern research actually shows, including where it is thin, is a longer story, and we tell it properly in the dedicated maca coffee guide and guarana vs. coffee guide.
On processing: the herbal extracts in both formats are produced by supercritical CO₂ extraction, with no ethanol or hexane used in the herbal extraction process. That is a statement about how the extracts are made, not about what they do. If you want to understand what the method actually involves, here is what SFE means in a functional coffee.
Mistakes people make with portable coffee
- Treating the formats as interchangeable. The stick needs a cup and hot water; the Tabs need nothing. Carrying the wrong one for the day you are having is the most common failure, and it is a packing error, not a product one.
- Assuming every CafeBank stick is the same recipe. The 10g stick and the Tabs contain maca and guarana only. The separate 20g Exclusive stick is a different formula that also contains tongkat ali. If you are choosing between them, the format comparison covers who each is for.
- Forgetting the dairy. Both formats contain milk: the 10g stick from its dairy creamer, the Tabs from lactose. If you are sharing with a colleague or packing for someone else, that matters to anyone with a milk allergy or lactose intolerance.
- Letting availability set your schedule. The whole point of a pocketable format is that coffee becomes possible everywhere, and everywhere quietly includes 9 p.m. Possible is not the same as sensible; your sleep will keep its own books.
Where CafeBank fits
If the desk-commute-travel pattern above describes your week, the two formats in this article are CafeBank SFE Maca & Guarana Coffee 10g, the single-serve stick for wherever hot water exists, and CafeBank SFE Maca & Guarana Coffee Tabs, the tablet format for wherever it does not. Both use supercritical CO₂ (SFE) extraction for their herbal components, with no ethanol or hexane in the herbal extraction process. Both contain milk. Neither contains tongkat ali.
And if it does not describe your week, because your coffee happens at home from beans you grind yourself, you do not need either format, and we would rather say so than sell you a solution to a problem you do not have.
Who should take a little extra care
Everything in both formats is a food, but two plain cautions apply. Both products contain caffeine from more than one source, so anyone who is pregnant or nursing, sensitive to caffeine, or keeping their intake low should count these like any other coffee. And both contain milk, so they are not suitable for anyone with a milk allergy or lactose intolerance.

Frequently asked questions
What do I need to prepare the CafeBank 10g stick?
Hot water and a cup. The product page's preparation is one line: empty one stick into 150–200 ml of hot water and stir until dissolved. There is no machine, filter, or brewing step.
Can I take coffee sticks or Tabs through airport security?
Sealed single-serve sticks and a flat Tabs sachet are small, solid, clearly labelled items. For US-bound flights, the TSA's powder guidance flags powder quantities over 12 oz / 350 mL in carry-on for possible additional screening; a handful of 10 g sticks is far below that. Rules differ by country, so check locally if you are carrying a large amount.
Are the Tabs just the 10g stick in tablet form?
No. The 10g stick is instant coffee intended for a cup of hot water, and it contains a dairy creamer. The Tabs are freeze-dried Arabica with the same two plant extracts compressed into tablets, with no dairy creamer and no added sugar, made for moments when brewing is not an option. The full differences are in our Tabs vs. sticks comparison.
Do the 10g stick or the Tabs contain tongkat ali?
No. Both contain maca and guarana only. Tongkat ali appears only in the separate CafeBank SFE Tongkat Ali Maca Guarana Coffee 20g formula.
Is there caffeine in these formats?
Yes, from two sources: the coffee itself and guarana, whose seeds naturally contain caffeine. If you track your daily intake, count a stick or a serving of Tabs as a caffeinated coffee, and see our guide to how much caffeine is too much for sensible boundaries.
Do these products contain allergens?
Both contain milk. The 10g stick includes a dairy creamer, and the Tabs' mild sweetness comes from lactose, a milk sugar. Neither is suitable for someone with a milk allergy or lactose intolerance.
