Best Portable Blenders (2026): Ninja vs. Oster

A portable blender is a different tool than a countertop one — this is about single servings on the go, not batch smoothies for a family. We compared the two Ninja Blast sizes against Oster’s competing GoMAX to see which cordless option is actually worth it.

How we compared these

We cross-referenced real amazon.ca review data (rating, review volume, and current pricing) across all three, since portable blenders don’t have the same depth of independent lab testing that larger countertop appliances get. We did not receive any of these products for free from the manufacturers, and we didn’t test physical units ourselves for this post — the pros and cons above reflect verified review data and product specifications, not firsthand testing.

If you need to blend more than one serving at a time, see our countertop blender guide instead.

#1

Ninja Blast Max Portable Blender (22oz, Twist & Go)

ASIN: B0DD4FTRJV

Pros
  • 4.3-star rating across 473 reviews on amazon.ca, Amazon's Choice, 200+ bought in the past month
  • Best value for money: Auto-iQ Crush and Smoothie programs, a dishwasher-safe twist-and-go vessel, and the largest capacity of the three (22oz) — at time of research it was also 31% off list price, making the most full-featured option also the best-priced
  • Cordless, USB-C rechargeable, leakproof lid for on-the-go use
Cons
  • Bulkier than the smaller original Ninja Blast

The one to buy if you want the most capable option and don't mind the larger size.

Ninja Blast Portable Blender (16oz, USB-C)

ASIN: B0C6V6DRS4

Pros
  • 4.2-star rating across 439 reviews on amazon.ca — the most-reviewed of the three
  • The cheapest of the three, with a genuinely compact size that fits a bag or car cupholder better than the larger Max
  • Stainless steel blending vessel with a leak-proof sip lid
Cons
  • No Auto-iQ presets — manual blending only
  • Smaller 16oz capacity limits it to single servings

The right pick if ultra-compact size and the lowest price matter more than presets.

Oster GoMAX Portable Blender

ASIN: B0FQHFHZ2Y

Pros
  • Amazon's Choice for this search
  • 20oz capacity splits the difference between the two Ninja sizes
  • One-handed drinking design, USB rechargeable
Cons
  • The most expensive of the three despite far fewer reviews (118) than either Ninja model
  • 4.2-star rating, essentially tied with the cheaper Ninja Blast

Worth considering mainly if you specifically prefer Oster's one-handed design — the numbers alone favor either Ninja.
