Three current Hamilton Beach 14-ounce personal-blender packages look similar at a glance, but the cup count changes who they serve. The useful comparison is not a bigger-capacity promise: all three blend one nominal 14-ounce jar at a time on a corded base.

One jar or two?

The 51101AG and 51101BG pages each list one personal jar and one travel lid. They are label/finish variants in the same functional setup: the AG page calls it Personal Creations; BG is Personal Blender. The 51171 Coral and 51172 Tranquil Blue pages also list one 14-ounce jar with travel lid. The supported choice among those four codes is finish, not a documented speed or power tier.

The 51102G package includes two separate 14-ounce jars and two travel lids. That can save a wash between two people's drinks, or let one clean cup wait for later. It still uses one motor base. Blend in one jar, then the other; do not add the nominal capacities together when estimating a single batch. If you regularly need a large shared recipe, a pitcher with a larger documented volume is the relevant comparison.

The manual makes this a cold, attended routine

Each exact page links the July 2024 Use & Care guide 840379000. Its model table lists 51101, 51102, 51171, and 51172 and notes that suffix letters may follow the listed codes. The guide specifies 120 V, 60 Hz, and 1.75 A, but not a watt rating. It tells you to add liquid before other ingredients—one-half to one cup, and enough to cover the blades—secure the lid, lock the jar on its base, and use ON for 15 to 30 seconds or Pulse until you reach the desired consistency. You remain involved rather than relying on a named unattended program.

All of these plans are corded. A travel lid helps move the finished drink; it does not make blending battery-powered. The guide prohibits hot food or liquids, and it says to add ice or frozen ingredients after liquid. That supports a cold drink with frozen additions, not ice-only crushing. Dry grinding is not established, and hard foods such as cheese, crackers, and meat are cautioned against. A product image or a broad “smoothie” claim should not override these instructions.

Cleanup and batch expectations

The product pages call the jar, blades, and lids dishwasher-safe; the guide narrows that to top-rack cleaning and warns against Sanitize. Keep the motor base, cord, and plug dry. The jar capacity is nominal, not a safe fill amount. The manual does not set a numeric maximum or guarantee a particular finished quantity, so a strict serving-size requirement deserves a model with an explicitly stated safe-use line or a larger vessel.

A quick choice rule

  • Choose 51101AG/BG or 51171/72 if one small cup is enough and a specific finish matters.
  • Choose 51102G if you value a second jar and lid more than a larger single batch.
  • Choose a full-size pitcher if you share drinks, need more volume, or want different control modes.
  • Choose a documented cordless model if you need to blend away from an outlet; these units are not cordless.
  • Do not choose any of these for hot liquids, dry grinding, or ice-only work on the evidence available.

Before ordering, verify the exact SKU in the product title and in-box list. Similar names can hide a one-cup package versus a two-cup package, and category filters are not a substitute for the exact page or operating guide. Availability also changes: an Add to Cart button is a dated offer observation, not a guarantee of continued stock.
