Three portable blenders compared on motor power, battery life, and cleanup, using manufacturer specs and aggregated buyer feedback — not an in-house lab test.

A portable blender’s job is simple: make one smoothie, get cleaned, and be ready again tomorrow. This comparison uses manufacturer specifications, published third-party reviews, and aggregated verified-buyer feedback for a corded personal blender and two rechargeable, battery-powered blenders. BuyingBench did not purchase or physically test any of these three blenders; see the evidence and review record below for what this article is based on.
A note on scope: this article previously referenced other portable blenders, including a BlendJet model. Roughly 4.8 million BlendJet 2 units were recalled on 28 December 2023 for fire and laceration hazards (CPSC recall 24-069), so we’ve excluded that model from this comparison rather than recommend it. BlendJet Inc. has since gone out of business and the replacement remedy is no longer available, so CPSC’s current advice is to discard an affected unit — see our full write-up.

BuyingBench Research Score — these reflect our comparative analysis of manufacturer specifications and aggregated verified-buyer feedback, not a hands-on lab test.
The Hamilton Beach Personal Blender (51132) is the budget pick: it’s corded rather than battery-powered, which means no charge cycle to manage but also no cordless portability, and buyer feedback consistently praises its simplicity and low price. The nutribullet GO is a compact, grip-and-go rechargeable option from a well-known blender brand, well suited to single servings away from an outlet. Our overall pick is the Ninja Blast (BC151BK): its larger 18 oz cup, multiple blend programs, and cordless rechargeable design give it the strongest all-around balance of capacity and convenience, even though it costs more than the other two.
The Ninja Blast’s larger cup and multiple blend programs make it the most versatile of the three.
The nutribullet GO is compact and easy to carry for single-serving use away from an outlet.
The Hamilton Beach 51132 is the simplest and least expensive option, with no battery to charge or manage.
The Hamilton Beach requires an outlet, unlike the two rechargeable options.
Neither rechargeable blender’s jar is dishwasher-safe according to manufacturer guidance; both recommend hand washing.
Ninja Blast (BC151BK)
The Ninja Blast's larger cup, multiple blend programs, and cordless design make it the strongest all-around portable blender in this comparison.

BlendJet 2 blenders were recalled for fire and laceration hazards. BlendJet Inc. is out of business, the free replacement is gone, and CPSC's current advice is to stop using the blender and throw it away.
