The Ninja Blast is the best portable blender for most people: RTINGS has tested it, it charges by USB-C and it blends 18 ounces in the cup you drink from. Want it cold for hours? The NutriBullet Flip has an insulated steel tumbler. Before buying any used portable, check CPSC recalls.
4 picks, best first. Price bands are from Amazon as of Oct 24, 2026.
Mostly, if you check recalls and skip hot liquids. The BlendJet 2 recall covered 4.8 million units, and the maker has since gone out of business, so its free fix is gone. NutriBullet warns against blending hot ingredients in sealed cups.

Yes, that is what tumbler and personal blenders are for. RTINGS’ protein-shake pick ships with two 24-ounce travel jars, and the BlendBOSS blends in a 26-ounce tumbler.

A strong full-size blender won’t; budget and personal machines may need extra liquid or a stir. Consumer Reports’ smoothie score rewards drinks with few chunks, skins or stringy bits.

Portable that keeps it cold
RTINGS has tested the Flip. Its stainless tumbler is insulated, and NutriBullet says it keeps blends cold for up to 24 hours.
NutriBullet’s own test counts 14 or more 30-second cycles per charge with water and protein powder; frozen-heavy blends will drain it faster.

Bigger portable with programs
RTINGS has tested the Blast Max. Its detachable Twist & Go vessel leaves the motor base behind, so you carry a lighter cup.
Three Auto-iQ programs cover smoothies, crushing and blending. The collected price looked wrong, so we hide it.

Small amounts. The Ninja Blast listing says it blasts through ice and frozen ingredients; heavy frozen loads drain the battery faster.
NutriBullet says the Flip gets 14 or more 30-second cycles per full charge in its own test with water and protein powder.
Check your serial number. CPSC says units with serials starting 5201 to 5542 may be recalled for overheating and blades breaking, and notes BlendJet has gone out of business, so the remedy is no longer available. Stop using a recalled unit.
No. Sealed vessels can build pressure; NutriBullet gives that warning for its sealed cups.
A corded personal blender is stronger and cheaper. Choose portable only if you blend away from an outlet.
The Ninja Blast for simplicity, the Blast Max for a bigger 22 oz detachable cup.
