Black & Decker FusionBlade Blender Jars

Why I reached for these jars

I’ve been using Black & Decker’s FusionBlade system on and off for a few years, mostly for weekday smoothies and the occasional sauce. My original single-serve cup was looking tired, so I picked up the FusionBlade jars set to expand capacity and refresh the blade assembly. After several weeks of daily use—smoothies, crushed-ice drinks, pesto, and quick purees—I have a good sense of where these jars shine and where they come up short.

For simplicity, I’ll call them the FusionBlade jars.

What you actually get

The kit includes two 20 oz plastic jars, two twist-on travel lids, and the FusionBlade blade base (the stainless-steel blade assembly that threads onto the jars). You attach the jar—with the blade base screwed on—to your FusionBlade motor base to blend, then swap the blade base for a travel lid to take your drink on the go.

It’s worth clarifying: this set is not a full blender. It’s an accessory bundle for the FusionBlade ecosystem. You’ll need a compatible motor base to power it.

Key specs:
- Capacity: 20 oz per jar
- Quantity: 2 jars with travel lids
- Blade: Stainless steel FusionBlade assembly
- Dishwasher-safe jars; BPA-free
- Warranty: 2-year limited (Spectrum)

Compatibility: what worked for me

These jars clicked into both a personal FusionBlade motor base and a full-size FusionBlade base I keep for larger batches. The lock-up was positive on both, and there was no wobble once engaged. If you’re using an older base, the safe bet is to confirm it’s part of the FusionBlade line—branding matters here—and that the locking tabs and threads match the blade base included in this kit. If your base says FusionBlade and your existing cup uses a similar twist-and-lock blade assembly, you should be fine.

Tip: Check the condition of your base’s drive socket before pairing new accessories. Excessive wear there can cause noise, slippage, or poor blending performance regardless of the jar you use.

Build and design

The jars are lightweight but feel sturdy enough for everyday blending. The plastic has held up well against repeated dishwasher cycles (top rack) and hasn’t clouded. The blade assembly has a reassuring heft; the stainless-steel blades are slightly offset to pull ingredients down, and they’ve stayed sharp through plenty of ice and frozen fruit. The included gaskets seat cleanly and, when properly aligned, create a drip-free seal.

The travel lids twist on easily and are good for commuting or gym-bag carry—no dribbles in my car cup holder. I still treat them as “upright carry” lids rather than toss-them-sideways lids.

One minor design note: at 20 oz, these are single-serve containers. They’re perfect for one-person smoothies, sauces, or baby food portions, but they’re not for big batches. If you’re used to 24–32 oz cups, plan on blending two rounds.

Performance: smoothies, ice, and purees

• Smoothies with frozen fruit: With about 8–10 oz of liquid (milk, water, or juice), frozen fruit blends to a smooth, drinkable texture in 30–45 seconds. I got the best results by starting at a lower speed (on the full-size base) or pulsing first (on the personal base), then ramping up. Minimal stalling, no air cavitation if I respect the fill line and add enough liquid.

• Crushed ice and blended ice drinks: The FusionBlade assembly handles standard ice cubes, but the technique matters. Pulse to break up the cubes before holding a steady blend. If you go full power on a jar packed with dry ice, it will roar and can rattle; a splash of liquid tames both noise and stress on the blade.

• Purees and sauces: For pesto, salsa, and quick cooked-vegetable purees, the small jar size is an advantage—ingredients circulate well without sticking to the sides. For thicker mixtures, a quick stop-and-shake midway speeds things up.

A word on hot ingredients: like most personal blender jars, these are not designed for blending steaming-hot liquids under a sealed lid. Let soups cool slightly, or use short pulses with caution to vent steam.

Noise and vibration

Noise is typical of compact blenders—mid to loud depending on load. Frozen fruit with liquid blends relatively quietly. Straight ice, dry or minimal-liquid blends, and harder ingredients get loud and can introduce a shrill resonance, especially on a hard countertop. A small silicone mat under the motor base cuts the resonance noticeably. Ensuring the blade base is fully seated and the jar is not overfilled also helps.

Ease of use and cleaning

• Assembly: The threads engage smoothly, but like any twist-on system, it’s possible to cross-thread if you rush. I make a half-turn backward until I feel the threads drop in, then tighten. Snug is enough—overtightening can deform the gasket and invite leaks later.

• No-leak performance: With the gasket correct and the base snug, I didn’t experience leaks during blending. If you see drips, check for a twisted gasket or food debris on the sealing surface.

• Cleaning: The jars are dishwasher-safe and clean up well. I usually hand-wash the blade assembly: a cup of warm water, a drop of dish soap, and a 10-second blend does the trick, followed by a rinse. Periodically remove the gasket to clean any trapped residue—this keeps odors at bay and maintains a good seal.

As with all plastic jars, strongly pigmented ingredients (turmeric, some berries) can stain if left to sit. Rinse soon after use to avoid discoloration.

Durability and maintenance

After a steady routine of daily blends, the blades show no nicks, the gasket remains pliable, and the jar threads are still crisp. The travel lids have picked up minor cosmetic scuffs but seal fine. Long-term, the gasket is the consumable—inspect it periodically and replace if it hardens or cracks. The 2-year limited warranty from Spectrum is a reassuring backdrop; keep your proof of purchase.

Everyday usability

• Portioning: 20 oz is a practical “grab-and-go” size. For calorie-dense smoothies, it’s just right; for post-workout shakes with ice, you may find you’re near the cap if you add lots of mix-ins.

• Footprint and storage: The jars don’t take much space, and the lids stack. The blade base is compact, and it’s handy to have a dedicated blade for the travel jars so you’re not swapping from a larger pitcher every time.

• Ergonomics: The jar shape is easy to hold, and the mouth opening is wide enough for cleaning brushes and scoops.

What I wish were different

• Noise spikes on harder loads are real. They’re not unique to this system, but if you’re sensitive to sound, plan your blends or use a mat.

• Capacity might be limiting if you routinely make larger smoothies. That’s the trade-off for portability.

• Threads require a touch of care. Cross-threading is avoidable, but it’s the one area where rushing can lead to leaks.

Who these jars are for

• Singles and couples who want quick, portable blends without committing to a full-size pitcher every time.
• Existing FusionBlade owners looking to replace a worn cup and blade, or add more cups for a household.
• Cooks who appreciate small-batch purees and sauces that don’t get lost in a big blender jar.

If you’re a meal-prep power user making 32 oz smoothies or hot soups daily, a larger, vented container will serve you better.

Bottom line

The FusionBlade jars deliver exactly what I want from a personal blending setup: reliable sealing, effective stainless-steel blades, compatibility with both personal and full-size FusionBlade bases, and easy cleanup. They’re straightforward, BPA-free, and backed by a 2-year limited warranty. Noise can jump with tough blends and the 20 oz capacity won’t suit everyone, but neither is a deal-breaker for what these jars are meant to do.

Recommendation: I recommend the FusionBlade jars to anyone already in the FusionBlade ecosystem who wants a practical, grab-and-go single-serve option. They refresh older setups, add convenient capacity, and handle smoothies, ice, and everyday purees without fuss—so long as you respect the fill line, seat the gasket correctly, and give the blade base a proper snug.
