Description
The Mr. Coffee 2191951 is a compact five cup programmable drip machine with a glass carafe, a Brew Later delay timer, an auto pause valve and a two hour automatic shut off. It is the smallest programmable machine Mr. Coffee fields, and the programmability is the reason to choose it over cheaper five cup brewers that offer nothing but a switch. The listing also mentions a filtration system and a reusable filter, so paper cones are optional rather than mandatory.
Placed against the rest of the coffee maker category, this occupies a specific gap: too small for a household, too big for a single mug, and cheaper than any pod machine to run. If you genuinely only ever want one cup, the machines in the single serve brewer category avoid the carafe entirely, though you then pay per pod rather than per pound.
Brewing System and Capacity
Standard gravity drip: water heated in the base, delivered over grounds in a basket, collected in a glass carafe on a warming plate. The listing states a 25 ounce capacity, which is the number to work from because it is unambiguous. Everything else in the marketing is expressed in cups, and cups mean different things depending on who is counting.
The carafe is described as ergonomic with ounce markings, which is a small but genuinely useful detail on a machine this size. Marked in ounces rather than in cups, the carafe lets you dose water for the mug you are actually filling instead of guessing against a five ounce convention nobody uses in practice.
Five Cups or Two Mugs, and Why the Numbers Differ
This product is a clean example of how the cup count on a drip machine misleads people. The title says five cups. The manufacturer’s own bullet point says the 25 ounce capacity brews up to two standard 12 ounce cups. Both statements are true and they describe the same machine, because the five cup figure uses the five ounce drip serving and the two cup figure uses a mug people would actually drink from. Twenty five ounces divided by five is five. Twenty five ounces divided by twelve is two.
It is worth being blunt about the practical consequence. If two people in a household each drink a twelve ounce mug in the morning, this machine brews exactly one round and no more. There is no headroom. Anyone who wants a refill, or a third drinker, needs a larger machine, and the jump from five cup to twelve cup usually costs less than people expect. The Mr. Coffee SK13-RB twelve cup is the same brand’s answer at the other end of the range.
Brew Later, Auto Pause and Auto Shut Off
The Brew Later feature is a delay timer: set a clock and a start time and the machine begins the cycle without you. This is the main thing separating the 2191951 from the switch only five cup machines this site also covers, and for a lot of buyers it is the whole purchase decision. Owner reviews commonly describe loading the machine at night and pressing brew in the morning, which suggests the interface is straightforward enough to use daily.
Auto pause stops the flow so you can pour a cup mid cycle and then resumes when the carafe is replaced. On a 25 ounce machine that matters less than on a twelve cup one, because the whole cycle is short, but it is there. The auto shut off cuts the warming plate after two hours. That is a safety feature more than a coffee one, and owner reviews commonly cite it as the reason for choosing the timer version over the plain model. Nothing in the record states whether the two hour period can be changed.
Filters and Running Costs
The listing says the machine includes a filtration system and a reusable filter. The Filter Type attribute confirms Reusable, so paper is optional. That removes the main recurring cost, and on a machine brewing 25 ounces at a time the paper cost was never large anyway. Mesh filters pass more coffee oils than paper does, which gives a fuller cup with a little sediment, so keep paper cones on hand if you prefer a cleaner result.
The phrase filtration system is doing unclear work here. The Special Feature attribute separately lists Water Filter, which would normally mean a charcoal cartridge treating the incoming water. No such cartridge is named in the bullets, no replacement part is referenced, and the only filter described in the copy is the reusable basket filter. The most likely reading is that filtration system and reusable filter are two names for the same component and the Water Filter attribute is an import artefact. Do not buy this machine expecting water treatment. If that is what you want, the Braun BrewSense KF7150BK carries a genuine charcoal cartridge and says so.
Footprint, Build and Missing Figures
The imported dimensions are 7.1 inches deep by 9.65 inches wide by 10.63 inches high. That height clears a standard wall cabinet comfortably, and the width is modest enough to tuck beside a kettle. The exterior finish field records the raw value black paint and chrome polish still wrapped in brackets, which is a scraping artefact rather than a description, but the underlying information is accurate enough: a black plastic body with chrome trim.
There is no item weight in this record at all. Every comparable machine on this site carries one, and its absence here means there is no way to say whether this is a light 3 pound unit or a more substantial one. The Model Name field is recorded as Cup Programmable, which is a truncated fragment rather than a name, and the real identifier is the item model number 2191951. The record dates the listing to March 2020.
What the Specifications Do Not Settle
No brew temperature, no wattage and no brew time appear anywhere. There is no statement of whether the carafe is dishwasher safe or whether replacement carafes are available separately, which matters on a small machine where a broken carafe can cost a meaningful fraction of the purchase price. The basket shape is not stated, so paper filter sizing needs to be confirmed against the manual rather than guessed.
It is not stated whether the delay timer retains its setting after a power interruption, which is the difference between a timer that works and one that has to be reset every time the kitchen circuit trips. Nothing describes the warming plate temperature, and given that a 25 ounce pot on a hot plate cooks faster than a large one, that is a relevant omission.
Who It Suits
This suits one person, or two people who each drink one mug and no more, who want the coffee ready at a set time and would rather brew from ground coffee than buy pods. The combination of a delay timer and a small carafe is genuinely uncommon, since most programmable machines are twelve cup models, and that is the specific gap this product fills.
Look elsewhere if anyone in the household wants a second cup, if you want brew strength control, or if you want water treatment. If the compact size is the priority but the timer is not, the Capresso mini drip coffee maker covers similar capacity, and the Keurig K-Mini is the pod alternative for anyone who would rather not deal with a carafe at all.
