Westinghouse 1200W Blender: Specs & What They Mean

The Westinghouse 1200W blender is a high-powered countertop appliance designed for crushing ice, blending frozen fruit, and making smooth sauces. Its 1200-watt motor and typical 2-liter jar (exact capacity varies by model) let you process tough ingredients quickly. This article explains the key specifications, what they mean in real use, and how to judge whether this blender fits your kitchen.

Formula

The calculator above estimates the electricity consumed during a blending session. The formula is:

Energy (Wh) = Power (W) × Time (min) / 60

Where:

• Power (P) – the blender’s rated motor power in watts (W). For a Westinghouse 1200W model, this is 1200 W.
• Time (t) – the actual blending time in minutes (min). Most recipes take 1–3 minutes.
• Energy – the electrical energy consumed, expressed in watt-hours (Wh) or kilowatt-hours (kWh) when divided by 1000.

The second output converts that energy into a cost using a typical electricity rate of $0.15 per kWh. Your actual rate may differ – check your utility bill.

Worked Example

Using the defaults from the calculator (1200 W, 2 minutes):

1. Convert minutes to hours: 2 min ÷ 60 = 0.03333 hours
2. Multiply by power: 1200 W × 0.03333 h = 40 Wh
3. Convert to kWh: 40 Wh ÷ 1000 = 0.04 kWh
4. Cost at $0.15/kWh: 0.04 × 0.15 = $0.006

So a 2-minute blend costs about 0.6 cents in electricity – negligible. Even a 10-minute continuous run would cost only 3 cents. The real cost of a blender is not electricity but the purchase price and the ingredients you put in it.

Key Specifications of the Westinghouse 1200W Blender

While exact specs vary by model (e.g., WSB1200 vs. others), the 1200W series generally shares these features:

• Motor: 1200-watt peak power (some models list 500W continuous). Peak power is what you get at startup; continuous power is sustained during blending.
• Jar capacity: Typically 2 liters (about 8.5 cups) – enough for 4–6 servings of smoothie.
• Jar material: Glass or Tritan plastic depending on the model. Glass is heavier but won’t scratch; plastic is lighter and less breakable.
• Blade assembly: 6-point stainless steel blades, designed to create a vortex that pulls ingredients down.
• Speeds: Usually 2–5 speed settings plus a pulse function. Some models have pre-programmed settings (smoothie, crush ice).
• Safety features: Non-slip feet, safety lock that prevents operation if the jar isn’t seated properly, and overload protection that shuts off the motor if it gets too hot.

Always check the specific model’s manual for exact numbers – these are typical, not universal.

How the 1200W Motor Affects Performance

Watts measure the rate of energy use. In blenders, higher wattage generally means more torque and faster blade speed, which translates to better crushing power. A 1200W motor is considered mid-high range – it can handle ice cubes, frozen fruit, and fibrous vegetables like kale or celery without stalling, but it may not be as effortless as a 1500W+ commercial unit.

For home use, 1200W is enough for most tasks. You can make:

• Frozen fruit smoothies (if you add liquid first)
• Crushed ice for cocktails or snow cones
• Nut butters (small batches, with patience and scraping)
• Hot soup (the friction heats the liquid – but check your model’s manual; some are not rated for hot liquids)

The key is the blade design and jar shape working with the motor. A 1200W motor with a poor blade design will underperform a 900W with a well-designed vortex. Look for a jar that tapers at the bottom – that helps pull ingredients into the blades.

Common Problems and How to Fix Them

Owners report a few recurring issues with this class of blender. Here are the most common and what to do:

• Blender won’t start: Check the safety lock – the jar must be twisted into the base until it clicks. Also check the outlet and that the speed dial is not on “0â€�.
• Motor smells hot or shuts off: This is the overload protector. Let it cool for 15–20 minutes, reduce the load (add more liquid), and try again. Don’t run it on high for more than 60 seconds continuously.
• Leaking from the bottom: The rubber gasket under the blade assembly may be worn or misaligned. Remove the blade assembly, clean the gasket, and re-tighten. Replace the gasket if cracked.
• Food gets stuck under the blades: Stop the blender, use a spatula to push food down, and add more liquid. Never use a spoon while the blender is running – risk of injury.
• Jar cracks: Glass jars can crack if you pour boiling liquid into them or if you over-tighten the base. Allow hot liquids to cool slightly before blending.

If the motor fails completely, it’s often cheaper to replace the whole unit than to repair it, since parts are not always available.

Comparing 1200W to Other Blender Powers

Blenders range from 200W (basic, for milkshakes) to 1800W+ (professional). Here’s a rough guide:

• 300–600W: Good for soft fruits, liquids, and light crushing. Struggles with ice and frozen ingredients.
• 700–1000W: Can handle ice and frozen fruit if you add liquid. Good for most home smoothies.
• 1200W: The sweet spot for home use – handles ice, frozen fruit, and tough greens with ease. May need occasional scraping for thick mixtures.
• 1500W+: Commercial-grade. Can blend nuts, seeds, and even make hot soup from friction. Heavier and more expensive.

For a typical family, 1200W is plenty. If you plan to make large batches of nut butter daily, you might want more power, but for smoothies and sauces, 1200W is efficient and won’t waste electricity.

Cost of Ownership

The purchase price of a Westinghouse 1200W blender typically falls in the budget-to-midrange category (under $100, but prices vary). Beyond that, consider:

• Electricity: As shown in the calculator, running the blender costs pennies per session. If you blend 2 minutes daily, that’s about $0.18 per month at $0.15/kWh.
• Replacement parts: Jars, lids, and blades are sometimes available. A new jar can cost $20–40, which is often half the price of a new blender – so check availability before buying.
• Warranty: Most Westinghouse blenders come with a 1-year limited warranty. Keep your receipt.

Compared to a high-end blender that costs $400+, the Westinghouse is a low-risk investment. The main long-term cost is replacement if the motor burns out – which is more likely if you consistently overload it.

Safety and Usage Tips

Blenders are safe if used correctly. Follow these guidelines:

• Always add liquid first (water, milk, juice) before adding frozen or solid ingredients. This protects the blades and motor.
• Never fill the jar past the “maxâ€� line – hot liquids expand and can overflow.
• Do not blend hot liquids (above 60°C/140°F) unless the manual says it’s safe. Steam pressure can blow the lid off.
• Use the pulse function for crushing ice – it gives you control and prevents over-processing.
• Clean the jar immediately after use. Fill with warm water and a drop of dish soap, blend for 30 seconds, then rinse. Never submerge the motor base.
• Keep fingers and utensils out of the jar while the blades are spinning. Always use the tamper (if included) or a spatula with the blender off.
• If the motor stalls, turn it off, unplug, and clear the blockage. Never force it.

These habits will extend the life of your blender and prevent accidents.

Alternatives to the Westinghouse 1200W

If you’re comparing, consider these types of blenders:

• Personal blenders (300–500W): Great for single-serve smoothies, but not for large batches or heavy ice.
• Immersion blenders (hand blenders): Convenient for soups and purees directly in the pot, but not for crushing ice or making thick smoothies.
• High-performance blenders (1500W+): Brands like Vitamix or Blendtec (not specific to Westinghouse) – they’re pricier but offer smoother results and longer warranties.
• Commercial blenders: Heavy-duty, expensive, and overkill for home.

For most home cooks, a 1200W countertop blender is the best balance of power, price, and versatility. If you only make simple shakes, a cheaper 600W might suffice; if you’re a smoothie enthusiast who wants perfectly silky results every time, consider stepping up to a 1500W model.

Frequently Asked Questions

Can the Westinghouse 1200W blender crush ice?

Yes, most 1200W blenders can crush ice, especially if you use the pulse function and add a little water. For best results, use ice cubes that aren’t too large, and don’t overload the jar. Some models have a dedicated “crush ice� button – check your manual.

Is 1200W enough for making nut butter?

It’s possible but requires patience. You’ll need to stop and scrape down the sides frequently, and the motor may heat up. For large batches, a higher-wattage blender is better. For small amounts (a cup of nuts), 1200W can work.

How loud is a 1200W blender?

Blenders in this power range typically produce 80–90 decibels at ear level – similar to a vacuum cleaner. It’s not quiet, but it’s not unbearably loud. Using a towel under the base can reduce vibration noise.

Can I blend hot soup in it?

Only if the manual explicitly says it’s safe. Most blenders with a plastic jar are not rated for hot liquids above 60°C (140°F). Glass jars can handle higher temperatures, but the lid and gasket may not. Always let soup cool slightly before blending.

What does “peak power� vs “continuous power� mean?

Peak power is the maximum wattage the motor draws briefly at startup – it’s a marketing figure. Continuous power is what the motor can sustain over time. A 1200W peak might mean only 500W continuous. For heavy blending, continuous power matters more. Check the spec sheet for both numbers.

How do I clean the blender properly?

Fill the jar halfway with warm water, add a drop of dish soap, and run the blender on high for 30 seconds. Rinse thoroughly. For stubborn residue, use a bottle brush. Never put the motor base in water – wipe it with a damp cloth.
