How to Calculate the Real Output of Horsepower in Blender Machine

As discussed previously here, one of the essential factors that you need to check before buying a blender is to make sure you will get tremendous or sufficient power comes out from the motor, which correlates to the machine workload capacity itself.

The easiest clue for this is to find a blender that stated at least has 1 Horsepower (HP) motor output on its peak level that would be simply perfect for you.

The top 3 blender brands so far: Vitamix, Blendtec, and Ninja Kitchen, are competing to provide powerful blender with average 1-2 horsepower machine, while some of the blender models which designed for a professional user can generate more than 3 HP motor output.

Let’s Reveal the Truth Behind Horsepower in a Blender

Probably for some of you now wondering why we need that kind of huge power from a blender? Some of the people prefer to buy a cheap blender, but some of the others could also looking a powerful blender that can be utilized for many other things, like making peanut butter, make a dough, etc. So no wonder if there still blender manufacturers compete to provide a blender with a decent machine.

But before we discuss further regarding the fact of horsepower in blender machine, let’s find out the definition of horsepower itself in the electrical machine.

Horsepower in the electrical machine

Based on Wikipedia, horsepower is a unit in the foot-pound-second that was adopted in the late 18th century by James Watt, to compare the output of steam engines with the power of draft horses. It was later expanded to be used in other types of engineering and machinery, including an electric motor.

The electrical power level of 1 HP is approximately equivalent to 746 watts (W). To convert HP to W, do the multiplication with 746 and to convert from watts to HP, multiply with 0.00134.

1 HP = Watts * 0.00134

Wattage calculation

The power (P) in watts (W) is equal to the voltage in volts (V), times the current (I) in amps (A):

P = V * I

The marketing words vs. the reality

There’s a solid reason for our suggestion to take blender that stated at least has 2 HP output. In fact, regardless of the capability statement of providing a specific number of HP, the blender machine actually can never reach that number of output in the real deal.

Let’s reveal the truth, by evaluating some blender models from the 3 top brands: Vitamix 5200 Standard, Blendtec Classic 575, Ninja Ultima Blender.

Vitamix 5200 claims has Horsepower output 2.5 HPcheck at amazon

Vitamix 5200 Standard Real Horsepower

Vitamix claims that Vitamix 5200 Standard model has 2 HP motor output on peak level. With fact it has 120V and 11.5A, that will provide power 120V * 11.5A = 1,380 W.

Based on the formula earlier in this article, the real HP output wiil be: 1,380 * 0.00134 = 1.8492HP (92.46%)

Blendtec Designer 625 claims has Horsepower output 3 HPcheck at amazon

Blendtec Designer 625 Real Horsepower

Blendtec claims that Blendtec Designer 625 model has 3 HP motor output on peak level. With fact it has 120V and 13A which will provide power 120V * 13A = 1,560 Watt.

The real horse power output: 1,560 * 0.00134 = 2.0904HP (69.68%)

Ninja Ultima Blender claims has Horsepower output 2.5 HPcheck at amazon

Ninja Ultima Blender Real Horsepower

Ninja Kitchen claims that Ninja Ultima Blender model has 2.5 HP motor output on peak level. Along with the fact that it provides 1,500 W electrical power.

The real horse power output: 1,500 * 0.00134 = 2.01HP (80.4%)


From the examples above, we revealed that the marketing words could never reach exactly the same as the real output number the blender machine can provide. The closest one, based on samples above is Vitamix 5200 Standard model which has 92.46% real output towards what they stated.

There is a limitation of horse power output which always directly proportional with the wattage power level that the machine consumes.
