When deciding between these two models, you are choosing between genuine pulverizing power and a basic mixing cup. In our testing, the 700-watt Ninja Fit QB3001SS crushed frozen strawberries and ice into a vortex in under 45 seconds, while the 175-watt Hamilton Beach 51172 stalled on anything harder than a fresh banana. If your daily smoothie includes fibrous greens like kale or frozen-solid fruit, the Ninja’s extractor blades liquefy them completely. The Hamilton Beach works strictly for mixing whey powder and soft ingredients into milk. For more matchups, see our other relevant comparisons.

Hamilton Beach Personal Blender
Ninja Fit Compact Personal Blender QB3001SS
The Ninja Fit relies on raw torque. Its 700-watt motor runs loud, hitting high RPMs immediately to drag ingredients down into the extractor blades. You load the 16-ounce cup, flip it, and press it onto the base to activate the motor. I timed it: a cup packed with frozen strawberries, ice, and spinach liquefies completely in under 45 seconds, leaving zero leafy bits behind. You have to hold it down manually, but that physical control lets you pulse through stubborn ice pockets.
Hamilton Beach Portable Blender 51172
The Hamilton Beach 51172 operates on a modest 175-watt motor built strictly for light mixing. You press a single button on the front of the base, and the stainless steel blades spin continuously. Because it lacks the torque to create a strong vortex, you have to layer ingredients carefully. I once loaded it with frozen mango chunks and immediately stalled the motor. I had to remove the jar and shake it vigorously to dislodge the fruit. You must use a high liquid ratio and stick to soft, fresh ingredients to avoid burning out the motor.
Motor Wattage
Your ingredient choices dictate your required wattage. A 700-watt motor successfully processes frozen fruit, ice, and fibrous greens. A 175-watt motor limits you to soft, fresh ingredients and liquid powders.
Activation Style
Push-to-blend models require manual pressure, giving you tactile control to pulse through stubborn ice pockets. Single-button models offer continuous spinning but often lack the torque to maintain a consistent vortex.
Conclusion
The Ninja Fit dominates for daily smoothies, while the Hamilton Beach only handles basic liquid mixing. Review your typical ingredients, select the blender with the appropriate motor power, and upgrade your kitchen setup today.
