The discontinued Hamilton Beach Go Sport 51141 (black) and 51142 (white) are corded personal blenders built around one nominal 20-ounce double-wall Tritan drink jar. The model pages describe the same bottle, controls and included lid; the documented difference is the base finish. This is useful for an existing owner or for identifying a secondhand or remaining-retail listing: both exact U.S. product pages showed “No Longer Available” when checked, and retailer availability was not checked.

A bottle-first arrangement, not a small pitcher
The appeal is the one-step handoff from blending to drinking. Hamilton Beach lists one 20-ounce, BPA-free, shatterproof Tritan bottle, a stainless-steel removable blade assembly and a flip-top lid with a seal. The jar is inverted onto the base for blending; afterward, remove the blade collar and fit the lid. There is no separate serving pitcher or second blending cup in the listed package. Twenty ounces is the jar’s nominal capacity, not a stated safe fill line or a promise that a finished recipe yields that much. If one cold drink is your normal batch, the format is tidy. If you routinely prepare several portions, a family-size pitcher or a package with several confirmed vessels is a better match.
The manufacturer calls the bottle double-wall and says it helps keep drinks colder longer and reduce condensation. That describes the product’s design claim, not an independently measured temperature hold. It is also not a cordless blender: the motor base needs a wall outlet. “Blend, fill, and go” means carry the detached bottle after blending, not blend while walking or traveling. The maker says the slender bottle fits most car cup holders; fit still depends on the particular vehicle.
Manual Low, High and Pulse for cold mixtures
The exact pages list two speeds plus Pulse and advertise 600 watts peak power. The directly linked 840280001 Use & Care guide lists models 51141 and 51142 in its type B98 table, including letter-suffix variants, and gives 120 volts, 60 hertz and 220 watts. Keep the peak-power marketing figure distinct from the guide’s electrical rating; neither by itself establishes how smooth a particular recipe will be. The dial gives you manual control over Low, High and Pulse, but the maker does not list a timed smoothie program or an automatic cycle.
For a cold drink, follow the guide’s order rather than loading a dry cup of hard ingredients: it recommends putting ice or frozen ingredients in first so they sit above the blade when the jar is inverted, then adding the other ingredients. The troubleshooting section says to add at least one-half cup of liquid, or enough to cover the blades, when the mixture will not circulate. That is a starting-use instruction, not a maximum fill or a guaranteed serving size. The guide includes recipes with ice, but neither exact page makes an ice-only grinding claim; do not buy this pair for dry ice crushing, flour or spice grinding. The guide also says not to process hard foods such as cheese, crackers or meat and explicitly forbids hot foods and liquids. A hot-soup requirement rules it out.
Care instructions disagree, so use the conservative method
Each product page says the jar, removable blades and lid are dishwasher-safe. The directly linked guide is more restrictive: it instructs owners to hand-wash the jar and lid, while the blade assembly is top-rack safe only and must not go through the SANI setting. Since those are conflicting maker instructions for the jar and lid, treat that care point as unconfirmed. If dishwasher-safe bottle care is essential, this is not a confirmed fit; hand-washing the jar and lid follows the guide. Unplug before cleaning, keep the base and cord out of water, and handle the blade assembly carefully.
Where this older pair fits
Choose 51141 if the black finish is the one you are identifying, or 51142 for the white base; there is no evidence here that color changes performance. When selecting on capacity, two speeds, Pulse and the double-wall bottle, both belong to the same supported cold-drink plan. The separate Go Sport 51143G is not the same exact package: it is documented with a 20-ounce Tritan personal jar, but the 51141/51142 pages specifically describe the double-wall bottle, and ice-crushing claims differ. Do not transfer package details from one SKU to another.
If you need a new unit, the manufacturer page itself has no current offer; any remaining retailer listing should be checked for the exact model number and condition rather than assumed to be available. Hot blending, cordless operation and confirmed dishwasher-safe jar care are not supported needs for this family. For an existing owner or a clearly identified used or remaining-stock listing, the useful tradeoff is straightforward: a compact one-drink bottle and simple manual controls, with no extra vessels and several care/processing limits.
