Ninja Blast Portable Blender Review: Is It Worth Buying?

It suits single-serve drinkers at home, at the office or on the go. It is a weaker fit for heavy ice crushing, thick dips or sharing one charge across a family.

This review covers the BC151BK, the original US Ninja Blast in black. It is not the Blast Max, and we have not carried specifications across between the two. If you are choosing between them, our Ninja Blast vs Ninja Blast Max comparison covers the differences.

The Blast pairs a 7.4V rechargeable motor base with a stainless-steel blade assembly, separate power and blend buttons, and a soap-and-water cleaning cycle. Like most Ninja blenders, the vessel and lid come off the base for washing.

Check the marking on your own cup. The usable fill can sit below the 18oz headline, so never fill past MAX FILL. Published weights and dimensions also vary between sources, so treat the size figure above as approximate. A wall adapter is not listed in the box, so you need your own.

We judged the Blast on the things a daily smoothie drinker notices: texture, noise, carrying comfort, battery behavior and cleanup.

The findings in this review cover soft banana and berry smoothies and protein shakes, along with the tougher cases: spinach, kale, seeds, ice, large frozen fruit and thick hummus. Those cases are where a cordless cup shows its limits.

Load order matters: at least 6 oz of liquid first, then soft produce and powders, then frozen ingredients on top.

Fruit smoothies and protein shakes

This is where the Blast earns its place. Banana and frozen berries in milk blended evenly with no fruit chunks left behind, provided there was enough liquid. Protein powder mixed readily into milk, and the sip opening let a thick shake flow without a second cup.

Leafy greens, seeds and texture

Texture is the compromise. Berry skins and spinach left fine fragments, and seeds never vanished into a silky blend. Fibrous kale and celery needed extra blending and kept some texture. Thick hummus stayed coarse even after repeated repositioning, so skip dips.

Ice and frozen fruit

Ice alone can stall. Add enough liquid and the mixture circulates and breaks down, even into a decent slush. Large frozen mango or papaya chunks are harder than small pieces, and whole frozen strawberries sometimes needed a second cycle. Cut big fruit down before it goes in.

The Blast is tall and slim. It fits a backpack more easily than a small handbag, and it takes up little space on the counter.

Cup size, carrying weight and drinking lid

A filled cup with its motor attached feels noticeably heavy while you drink, despite the slim bottle shape. The sip cover clips back out of the way, though it can feel stiff when you snap it into place.

Drinking without the motor base needs a compatible bottom vessel cap. Inclusion varies by package, so check the box or buy the cap kit before you plan to leave the motor at home.

Controls, loading and stalled blends

Blending takes a press of the power button and then the blend button. The 30-second cycle can be stopped early. Flashing orange means blocked blades and solid red means recharge. A low battery can interrupt a blend unexpectedly, so a quick charge check before a commute pays off.

That charge check matters because stamina is the Blast's softest spot. A full charge takes about 2 hours using the supplied USB-C cable and a 5V 3A power supply. The cord is short, which limits how far the blender can sit from an outlet.

Ninja claims up to 15 cycles per charge, but that is a best-case number. Making a smoothie and running a cleaning cycle each use battery power. Repeat blends drain it faster, so expect fewer drinks than the headline suggests. Charge it before you leave.

The battery is not user-replaceable, and battery trouble goes through customer service.

Using one cup for blending and drinking saves washing a second vessel. The vessel and lid can go on the top rack with no heated cycle. The base and blades need hand cleaning with a handled brush, and the base must never go under water. Dry the charging port before you plug in.

Rinse before fruit residue dries and you will rarely need to scrub near the blades. The blade-base crevice does need a brush.

The Ninja Blast sits in the mid-priced band among personal blenders. It comes with a 1-year warranty and replacement vessels, lids and cords, though future stock is not guaranteed.

When another portable blender makes sense

Pick a different cordless model if you want a bigger cup, a longer battery or a finer texture. Our Cutify portable blender review and Ninja Blast Max review are good next stops.

When a plug-in personal blender is a better fit

If you blend at home, a plug-in personal blender avoids battery worries and tends to handle ice and thick mixes with less fuss. Our Ninja Fit blender review shows what that trade looks like.

Beyond the pick above, two routes are worth a look. If you want more cup or runtime, the Blast Max is the natural step to read about, though we have not carried any Blast specifications across to it. If you mostly blend at a counter, a plug-in personal blender is the simpler alternative.
