Let’s reveal the truth behind horsepower blender
As discussed previously here, one of the important factor that you need to check before buy a blender is to make sure you will get huge or sufficient power comes out from the motor, which correlating to the machine workload capacity itself. The easiest clue for this is to find a blender that stated at least has 2 Horsepower (HP) motor output on its peak level that would be simply perfect for you.
The top 3 blender manufacturers so far: Vitamix, Blendtec, and Ninja Kitchen, are competing to provide powerful blender with average 2-3 horsepower machine, while some of blender models for professional user can generate more than 3 HP motor output.
Horsepower in 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 power of draft horses. It was later expanded to be used in other types of engineering and machinery, including 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. For converting from watts to HP, multiply with 0.00134.
The power (P) in watts (W) is equal to the voltage in volts (V), times the current (I) in amps (A):
The marketing words vs. the reality
There’s a solid reason on our suggestion to take blender that stated at least has 2 HP output. In fact, regardless 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 Standard
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
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
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.
