Overview
A single-serve personal blender with a 26oz travel tumbler, 1200-peak-watt motor, and a leakproof flip-cap lid with a built-in chug spout and detachable straw. Built for smoothies and frozen drinks you blend and carry in the same cup.
The three Auto-iQ programs, Smoothie, Ice Crush, and Blend, replace manual speed control with fixed pulse-and-pause patterns, so texture is set by the program rather than how long you hold a button. Reviewers who compared it to smaller portable blenders they'd used before describe it as noticeably less prone to jamming on frozen fruit.

- 26oz leakproof tumbler with chug spout
- Detachable straw included
- Dishwasher-safe, BPA-free parts
Who it's for
Suits someone making a daily protein shake or frozen coffee drink who wants to blend straight into a cup they can carry out the door. Not a fit for anyone wanting a cordless or rechargeable blender, since it's outlet-powered, or anyone sensitive to noise at close range.
What buyers say
From Amazon customer reviews.
Reviewers consistently describe it as powerful enough to crush ice and blend frozen fruit without jamming, a step up from smaller portable blenders they'd used before, and the suction-cup base is called out for keeping it stable during hard blending. The recurring complaint is noise during ice crushing, and several reviewers caution to unscrew the blade assembly carefully to avoid injury.
Strengths and trade-offs
Drawn from this product's published specifications.
- Crushes ice to snow without jamming on frozen fruit
- Suction-cup base keeps it stable during blending
- Blends directly into a carry-out travel tumbler
- Three Auto-iQ presets give repeatable results
- Loud during ice-crushing cycles
- Outlet-powered, not cordless or rechargeable
- Blade assembly needs careful handling when removing
Performance notes
The 1200-peak-watt motor and stainless CrushBlade are built to take ice straight to snow, and four suction cups under the base keep it planted on the counter through hard blending rather than walking. The Auto-iQ presets combine pulsing and pausing automatically, so the same button press gives a repeatable result run to run.
