Bench take
The Ninja Blast Portable Blender BC151 is Ninja’s entry in the personal blenders category. On the category’s key decisions — cup size, blade and motor for frozen ingredients, lid and portability, cleaning — it deserves a place on any shortlist, provided the checks below confirm it fits your kitchen, your batch size and your care tolerance. This review does not claim hands-on laboratory testing: it assesses the product from its category, its maker’s line and the specifications buyers should verify on the manufacturer sheet for the exact variant they are buying.

Prices and availability change — the retailer page shows the current price for your exact variant. If the variant, size or colour differs from what you wanted, do not order it on price alone.
What this product is
A personal blender blends a single smoothie or shake directly in the cup you drink from. It is the right tool when one portion, speed and minimal washing matter more than large batches or heavy-duty blending. Within that category, the Ninja Blast Portable Blender BC151 sits as Ninja’s offering. The name itself tells you the most reliable facts — brand, product line and, where stated, size or capacity. Anything beyond that — exact dimensions, materials, warranty terms, care instructions — should be confirmed on the manufacturer sheet for your exact variant, because retailer listings for the same product frequently disagree.

Key decisions for this category
Cup size
Match the cup to your usual smoothie, not the largest offered. An oversized cup blends small portions poorly.
Blade and motor for frozen ingredients
Frozen fruit and ice are the test. A weak motor leaves chunks and strains; check what the maker actually rates it for.
Lid and portability
A leak-proof travel lid turns the cup into a bottle. If you drink at a desk or in a car, the lid matters as much as the blend.
Cleaning
A cup you rinse in ten seconds gets used daily. A base with food traps does not.
What to verify before buying
Before you buy the Ninja Blast Portable Blender BC151
- ✓ Cup capacity against your usual portion
- ✓ Whether it handles your frozen ingredients
- ✓ Travel lid quality and leak-proofing
- ✓ How fast the cup and blade rinse clean
Where the manufacturer sheet and a retailer listing conflict, this site follows the manufacturer sheet and flags the conflict. Never buy a personal blender on a single specification from a single listing.
Pros and cons — at a glance
These are the honest trade-offs for this type of personal blender, not a score. The strengths are what the category does well when the size and care needs fit; the watch-outs are the checks that decide whether this particular personal blender fits your kitchen.
What it does well
- ✓ Fits the personal blenders use case when cup size and blade and motor for frozen ingredients are checked first.
- ✓ From Ninja, a maker whose line is built around this category — spare parts, care guidance and variant information are easier to verify than for a no-name listing.
- ✓ The name states the key facts (brand, line and, where stated, size) — so you can match it to the manufacturer sheet before ordering.
What to watch
- ✗ Chunks in the smoothie — check this before buying, not after unboxing.
- ✗ The blade stalls — check this before buying, not after unboxing.
- ✗ Leaking lid — check this before buying, not after unboxing.
- ✗ Retailer listings for the same product frequently disagree on size, capacity or care — verify the exact variant on the manufacturer sheet.
How to buy it right — in 5 steps
- 1. Measure first. Check your counter, hob, cupboard and storage against the manufacturer dimensions for the exact variant — not the roundup photo.
- 2. Match the batch. Size and capacity should fit your usual cooking, not your largest party. A personal blender that is too big wastes space; one that is too small forces second batches.
- 3. Check the variant. Colour, size and included accessories change the price and the fit. Confirm the variant name on the retailer page matches the one you checked.
- 4. Run the verify checks below. Cup capacity against your usual portion; Whether it handles your frozen ingredients; Travel lid quality and leak-proofing; How fast the cup and blade rinse clean. If any check fails, pick an alternative from the list below instead of hoping it will work out.
- 5. Check returns before ordering. Confirm the retailer return window for your variant, so a wrong size or a damaged arrival is a swap, not a loss.

The winner is insideCommon mistakes to avoid
Chunks in the smoothie
Liquid first, then soft fruit, then frozen items last. Blend longer and shake the cup midway.
The blade stalls
Too little liquid or too much frozen food. Add liquid and blend in pulses.
Leaking lid
Check the seal and do not overfill past the marked line. Worn seals need replacing.
Cup smells
Rinse immediately after use. A soak in warm soapy water removes most odours.
Who it suits — and who should skip it

Frequently asked questions
Can a personal blender crush ice?
Some can, some cannot. Check the maker's rating — a weak motor will stall or dull.
Is it enough for a family?
No. It makes one portion at a time. Families need a full-size blender.
Can I blend hot liquids?
Most personal blenders are not rated for hot liquids. Check the manual before trying.
