Common types include: small personal blenders that blend and chop ingredients in the cup, battery-powered self-stirring travel mugs, and manual shaker-style bottles that use a whisk or internal mixing system to combine drinks.

Power options vary by model: some use a motor (listed in some items with ratings such as 250 watts), others run on small replaceable batteries (for example, 2 AAA), and many shaker-style bottles require no power and rely on a manual mixing mechanism.

Typical capacities range from about 12 ounces up to 24 ounces, with common sizes including 12 oz, 16 oz, and 24 oz.

Mechanisms include blade-based motors for blending, battery-powered electronic stirring, and manual shaker/whisk systems such as internal wire whisks.

Review summaries report generally strong blending performance for smoothies, shakes, and sauces, with users noting compact size and easy cleaning. Some reviewers mention occasional difficulty with very frozen items, and a few report these units are relatively quiet compared with larger blenders.
