Frequently asked questions

Very little — for most machines it lands in low single-digit dollars a year. A 1,000 watt blender run 3 minutes a day, 365 days a year uses about 18.3 kWh, which at 17.45¢ per kWh comes to roughly $3.18 a year.

The useful conclusion is that electricity cost should not influence which blender you buy. A machine drawing twice the power usually takes half as long to do the same job, so the totals converge anyway. The full arithmetic, with the rate source, is here so you can redo it with your own tariff.

Not reliably, and the number is less comparable than it looks. Some manufacturers publish continuous watts, some publish peak watts measured at the instant of maximum draw, and some publish horsepower or a nameplate amperage and no watt figure at all. Those are different measurements and putting them in one column implies a comparison that is not really there.

What actually decides whether a blender copes with a full jar of frozen fruit is container geometry — whether the jar shape keeps pulling ingredients back down onto the blades — and whether a tamper is included. The wattage guide explains what the number does and does not tell you.

Because it is the closest thing to an honest, legally binding durability statement that a manufacturer publishes. A warranty term is a company committing, in a document, to repair or replace its own motor for a stated number of years. When one brand writes several years into that document and another writes twelve months, they are telling you what they each expect their product to survive.

It is also almost never tabulated anywhere, which makes it cheap authority for anyone willing to read the documents. Ours is in one table, with each term linked to the manufacturer’s own warranty page.

In a countertop blender, only with care and only if the manual allows it. The danger is pressure, not heat: steam expands under a clamped lid until the lid leaves, taking the contents with it. That is a genuine burn injury, not a theoretical one.

The rules that matter are to fill well below the maximum line, remove the lid’s center cap so steam can escape, cover the gap with a folded towel, and start on the lowest speed. In a sealed personal blender cup, do not do it at all — most manuals prohibit it. The safety guide cites a manufacturer manual for every claim it makes.

An immersion blender, by a distance. There is no sealed vessel, so there is no pressure to build — you blend in the open pan the soup is already in. It is also easier to clean, which is why it is the machine that stays in use. Our immersion blender picks are here.

Mixed with liquid or frozen fruit, usually yes. A cup of nothing but ice cubes, usually not — the narrow cup that makes a bullet blender effective also means a solid load of ice jams against the blades instead of circulating.

Add liquid first. Almost every manufacturer recommends it, and that recommendation is about the machine’s lifespan as much as the texture. The full answer is here.

In a high-power countertop blender with a tamper, yes. In most mid-range blenders, with difficulty and in small batches. In a personal blender, no — the cup gives the mixture nowhere to move and the motor nowhere to cool.

Nut butter is the single most demanding thing a home blender does: a thick, barely-moving load run for minutes, with the motor near stall and airflow at its worst. It is the one job where an expensive machine genuinely earns its price. Here is what is realistic on each type.

It is called cavitation, and it is usually a loading problem rather than a power problem. Frozen fruit bridges above the blades, the blades spin in a pocket of air, and nothing moves.

The fix is order: liquid in first, then soft ingredients, then powders, then frozen or hard items last on top. Most manufacturer manuals specify exactly that sequence. If it still stalls, use the tamper, or blend a smaller batch — both work better than buying more watts.

A blender moves food through liquid; a food processor cuts food in air. That single difference explains everything else. A blender makes smooth things from wet mixtures; a processor makes chopped, sliced, shredded or doughy things from dry ones.

They are genuinely not substitutes, and no amount of attachments makes one into the other. The comparison sets out which jobs fall where.

It depends on three specific things, and if none of them apply to you the answer is probably no. Sustained thick loads (nut butter, thick bowls, dough); regular hot work; and a long ownership horizon where a multi-year warranty is worth real money.

If your honest use is smoothies with frozen fruit a few times a week, a competent hundred-dollar machine will do it and the difference will not show up in your kitchen. The buying guide is written to help you not overbuy.

High-power blenders are loud, and quiet operation is a legitimate buying criterion in an apartment or an early-morning house. We do not list decibel figures for most machines because most manufacturers do not publish one.

We are not going to estimate a measurement we did not take. Where a manufacturer does publish a figure, we print it and attribute it to them; where they do not, the cell says “not published”, which is the honest state of the information.

Check before you buy. Full-size blenders are commonly 17 to 20 inches tall assembled, and standard US worktop-to-cabinet clearance is about 18 inches. This is how people end up storing an expensive machine in a cupboard and using it half as often.

Measure your gap, and compare it to the height of the machine with the lid on. If it is tight, a low-profile jar is worth more to you than extra power.

No, and we say so on every page that ranks one.We do not own these machines, we have no test kitchen, and we do not accept free units. You will not find the phrase “in our testing” anywhere on this site because it would not be true.

What we do instead: compile the published specification from the manufacturer’s own documents, verify each warranty term against the manufacturer’s warranty page, compute the annual running cost and show the arithmetic, track the price live, and cite all of it so you can check the work. The full method is published.

Because everything here is checkable. Every specification links to the manufacturer document it came from, every running-cost figure shows its own arithmetic and names the electricity rate it used, and every warranty term links to the warranty page it was read from. You can reproduce a ranking, or disagree with it on the evidence.

That is a different kind of authority from a test lab, and a weaker one in some respects. It is also completely uncontested in this category: the sites that do own the machines do not publish running costs or warranty comparisons, and two of the highest-ranking ones put their prices behind a paywall.

Affiliate commissions, principally through the Amazon Associates program. If you buy after clicking one of our links, we may earn a percentage of the sale, at no extra cost to you.

What it does not buy: a ranking. Commission rates differ between products and we do not look them up when ordering a list — on several pages here the cheapest machine wins. Nobody has paid for placement, no product has been given to us, and there are no sponsored posts. The full disclosure is here.

Because we would rather show nothing than something stale. Prices come from Amazon’s API with the date of the last check printed beside them. If that data is older than 48hours, the number is removed automatically and the button falls back to “check price”.

It never falls back to the last number we knew. A price that quietly stopped being true is a small lie told to someone about to spend money.

No. Each score is a judgment compiled from published documents — the specification, the warranty term, the price at the time of writing, and the buyer profile named at the top of each list. The sub-scores that make it up are shown on the page so you can see what drove it.

Because they are not measurements, they never enter the structured data. There is no review-rating or aggregate-rating markup anywhere on this site — telling a search engine in code that we rated a product would contradict what we say in words.

Because a list where every product is excellent is an advert, and readers can tell — it is exactly why people add “reddit” to a shopping search. Naming a real, disqualifying reason not to buy something is the cheapest honest signal available to a publisher with no test lab, and it is nearly unclaimed in this category.

It costs us conversions on purpose. If the reason we name applies to you, we would rather you did not buy it.

Please tell us — corrections are the most useful mail this site gets. Email info@basketandblade.comwith a link to the manufacturer’s own document if you have one.

We fix verified errors within seven days and date the correction on the page rather than editing quietly. Anything safety-related jumps the queue. The correction policy is published in full.
