Its 14-ounce cup, 1.5-pound weight, six stainless steel blades, and one-button self-cleaning mode make it easy to carry and clean. The tradeoff is clear: it is built for convenience, not heavy-duty blending, dense mixtures, or regular ice crushing.

What Is the Mulli Portable Blender?
The Mulli Portable Blender is a small personal blender designed for people who want a quick drink without using a full-size countertop blender. It uses a built-in USB rechargeable battery, so you can charge it ahead of time and use it without keeping it plugged into an outlet during every blend.
Its size is the main appeal. At 8.9 x 3.3 x 3.3 inches and 1.5 lbs, it fits better in a gym bag, work bag, RV cabinet, dorm room, or small apartment than a traditional blender. The 14-ounce cup is enough for one smoothie or shake, not for family-size prep.
The design is simple: a plastic body, stainless steel blades, one-button operation, and a cleaning mode that helps rinse the blades after use. That makes it more useful for quick nutrition routines than for complex recipes.
Before You Buy: Treat this as a portable personal blender, not a replacement for a full-size kitchen blender. For best results, use soft ingredients, cut fruit into small pieces, add enough liquid, and avoid relying on it for hard ice or dense frozen blends.
Who Should Buy It?
Best For
- Gym users who want a quick protein shake after a workout.
- Commuters, travelers, students, or office workers who need a compact single-serve blender.
- Parents who want to blend small portions of soft baby food while following safe feeding guidance.
Skip If
- You want to crush ice often or blend thick frozen fruit with little liquid.
- You need to make multiple servings at once.
- You prefer a high-power blender for nut butters, dense sauces, or fibrous greens.
Design and Build Quality
The Mulli Portable Blender keeps the design clean and narrow, which helps it fit into tight storage spaces. The 3.3-inch width also makes it easier to hold than a wide countertop jar.
The plastic and stainless steel build is typical for a lightweight portable blender. The stainless steel blades add strength where it matters most, while the plastic body helps keep the weight down. At 1.5 lbs, it is light enough for travel but still heavier than an empty bottle, so you should account for that if you pack it daily.
The sealed charging port is a useful detail because portable blenders are often rinsed near water. You should still keep the charging area dry before plugging it in and follow the product instructions for safe charging.
How Well Does the Mulli Blender Perform?
With a 7.4V motor, 18,000 RPM speed, and six stainless steel blades, the Mulli Portable Blender is built for quick, light-duty blending. It performs best with soft fruits, protein powder, yogurt, milk, water, juice, or other thin liquids.
For smoothies and shakes, the key is preparation. Cut ingredients into small pieces, place liquid in the cup first when possible, and avoid packing the cup too tightly. This helps the blades pull ingredients down instead of spinning against a stuck mixture.
Dense ingredients are the main limitation. Large frozen chunks, hard ice, thick smoothie bowls, and fibrous produce can strain the motor and leave uneven texture. If those recipes are part of your daily routine, a stronger countertop blender will be the safer choice.
Cleaning, Charging, and Daily Maintenance
Cleaning is one of the Mulli blender’s strongest practical points. The one-button self-cleaning mode lets you add water, run the blades briefly, and rinse the cup after use. This is helpful when you make protein shakes or fruit smoothies that would otherwise dry around the blade area.
The container is described as dishwasher safe, which gives you another option for deeper cleaning. The included cleaning brush is useful around the blade base and lid area, where residue can collect after thicker drinks.
Charging is also simple. The built-in USB battery takes about three hours to reach a full charge, so it makes sense to charge it before travel, before work, or the night before a busy day. Because the battery is built in, it favors convenience over long-term serviceability.
Pro Tip: Rinse the cup right after blending, then run the self-cleaning mode with warm water before residue dries. For thicker shakes, use the cleaning brush around the blades after the rinse cycle.
Food Safety and Materials
Because this blender touches food, basic cleaning and safe use matter. The article-supported materials are plastic and stainless steel, and the blade assembly uses stainless steel blades. Do not assume extra certifications or material claims unless you verify them on the product label or listing.
For baby food, use extra care. Blend only age-appropriate cooked or soft ingredients, check texture before feeding, and follow your pediatrician’s feeding guidance if your child has allergies, swallowing concerns, or special dietary needs. A portable blender can help with small portions, but it does not replace safe food preparation.
Always keep the charging port dry before charging. Do not run the blender while it is plugged in unless the product instructions clearly say that is allowed.
How It Performs in Real Use
For Protein Shakes
The Mulli blender makes the most sense for protein powder, milk, water, or other thin liquids. It can help reduce clumps better than a shaker bottle when you give the blades enough liquid and avoid overfilling the cup.
For Fruit Smoothies
Soft fruits are the best match. Bananas, berries, ripe mango, yogurt, and milk-based blends should be more realistic than hard frozen chunks. Pre-cut fruit gives the 18,000 RPM blade setup a better chance to create an even texture.
For Baby Food Portions
The 14-ounce cup is useful for small batches of soft baby food. Use cooked or soft ingredients and check the final texture carefully before serving. Clean the cup and blade area thoroughly after every use.
For Travel, Work, and Small Spaces
The slim 8.9 x 3.3 x 3.3-inch body is easy to store in a small kitchen, dorm, RV, or office drawer. The USB rechargeable design is useful when outlets are limited, but you still need to charge it ahead of time.
Setup Tips Before First Use
- Charge the blender fully before your first use, especially if you plan to take it outside the home.
- Wash the cup, lid, and blade area according to the product instructions before blending food or drinks.
- Cut fruit into small pieces so the blades can pull ingredients down more easily.
- Add enough liquid for movement. Thick mixtures can stall or blend unevenly.
- Do not overfill the 14-ounce cup, since the contents need room to move while blending.
- Check that the cup is assembled correctly before starting the motor.
Pros and Cons
Pros
- Compact 8.9 x 3.3 x 3.3-inch body is easy to store and carry.
- 14-ounce capacity is practical for one smoothie, shake, or small baby food portion.
- Six stainless steel blades and 18,000 RPM speed are useful for soft, pre-cut ingredients.
- USB rechargeable battery makes it more flexible for work, gym, travel, and small spaces.
- One-button self-cleaning, dishwasher-safe container, and cleaning brush simplify upkeep.
Cons
- Not ideal for ice, large frozen chunks, dense mixtures, or heavy-duty blending.
- 14-ounce cup is too small for families or meal prep batches.
- Built-in battery favors convenience, but it is not described as replaceable.
Is It Worth the Price?
The Mulli Portable Blender is worth considering if you want a small, simple blender for everyday light use. Its value comes from the mix of portability, USB charging, one-button cleaning, and a size that fits where larger appliances do not.
It is a smart buy for buyers who care more about convenience than raw power. You get the most value if your recipes are basic: protein shakes, soft fruit smoothies, and small portions of blended food.
It is not the best fit if you need a strong kitchen blender for ice, dense frozen recipes, large batches, or frequent heavy use. In that case, spending more on a larger personal or countertop blender may make more sense.
How It Compares to Alternatives
Compared with larger personal countertop blenders, the Mulli Portable Blender is easier to carry and store, but it gives up power and batch size. Compared with higher-capacity portable blenders, its 14-ounce cup keeps the design compact but limits how much you can make at one time.
The Mulli makes the most sense if you want a light-duty USB blender for simple drinks. If you care more about thick smoothie bowls, crushed ice, or multi-serving prep, compare it with a stronger plug-in blender before buying.
Frequently Asked Questions
Is the Mulli Portable Blender good for daily smoothies?
Yes, it can work well for simple daily smoothies made with soft fruit, yogurt, protein powder, and enough liquid. It is best for one serving at a time, not thick smoothie bowls or large batches.
Can the Mulli Portable Blender crush ice?
It is not ideal for regular ice crushing. The article-supported specs point to light-duty blending, so small softened frozen pieces with liquid are more realistic than hard ice cubes.
How big is the cup?
The cup capacity is 14 ounces. That is suitable for a single smoothie, shake, or small baby food portion, but it is too small for family-size blending.
How long does it take to charge?
The built-in USB battery reaches a full charge in about three hours. Charge it before leaving home if you plan to use it at work, the gym, or while traveling.
Is the battery replaceable?
The battery is not described as replaceable. The built-in USB design is convenient, but buyers who want serviceable parts should check the product listing or manual before purchasing.
Is it safe for making baby food?
It can be used for small portions of soft baby food when you prepare ingredients safely and clean the blender well. Always follow age-appropriate feeding guidance and speak with a pediatrician if your child has allergies, swallowing concerns, or special needs.
What accessories are included?
The article-supported package includes the blender unit, USB charging cable, and cleaning brush. No extra travel cups or special attachments are confirmed.
Who should skip this blender?
Skip it if you need strong ice crushing, thick frozen blends, nut butters, or multiple servings. It is better for light, portable use than heavy kitchen prep.
The Bottom Line
The Mulli Portable Blender is a good fit if you want a compact USB blender for simple single-serve smoothies, shakes, and soft baby food. Its biggest strengths are portability, easy cleaning, and simple use, while its main limitation is light-duty power.
Buy it for convenience and small portions. Skip it if you need a stronger blender for ice, dense frozen recipes, or larger batches.
