KOIOS BL337B 900W Personal Smoothie Blender, Grey Blue, 3-Cup Set

Product Overview

The KOIOS BL337B is a compact corded personal blender designed for smoothies, shakes, juices, frozen drinks, and other small-batch blending tasks. This Grey Blue configuration uses a motor rated at up to 900 watts and operates through a simple twist-lock system rather than a conventional multi-button control panel. The motor can reach approximately 23,000 revolutions per minute under documented operating conditions.

The set includes three portable blending cups: two 23-ounce cups and one 17-ounce cup. A removable six-leaf stainless-steel cross blade attaches to the selected cup before the container is inverted and locked onto the motor base. The cups are made from BPA-free plastic and can be fitted with drinking or storage accessories after blending.

The BL337B is intended for cold food and beverage preparation, including fruit smoothies, protein shakes, frozen fruit mixtures, and crushed-ice drinks. The cups and lids are dishwasher safe, while the motor base requires manual cleaning. An integrated safety-lock mechanism prevents normal operation unless the container is correctly installed, and thermal protection can stop the motor if excessive heat develops during operation.

Common Uses

• Preparing individual fruit smoothies.
• Mixing protein shakes.
• Processing frozen fruit with suitable liquid.
• Crushing small quantities of ice for cold beverages.
• Preparing fruit and vegetable drinks.
• Mixing milkshakes and similar cold beverages.
• Preparing small batches of pureed ingredients.
• Blending drinks directly in portable cups that can be fitted with lids after processing.

Maintenance and Care

The blender should be disconnected from electrical power before cleaning or disassembly. Cups, lids, lip rings, and removable food-contact accessories should be washed soon after use so residue does not dry around threads and seals.

The BPA-free cups and lids are dishwasher safe. Hand washing with warm water and mild detergent is also suitable and can reduce the amount of food residue around threaded areas.

The detachable cross-blade assembly should be handled carefully because its stainless-steel edges remain exposed when removed from a cup. The blade seal should be inspected periodically for damage, displacement, or buildup.

The motor base contains electrical components and should not be immersed in water or placed in a dishwasher. Its exterior can be wiped with a damp cloth after the appliance has been unplugged.

Safety Information

The six-leaf blade assembly contains sharp stainless-steel cutting surfaces. Fingers and utensils should remain away from the blades, particularly when the assembly is removed from a cup.

The blender uses a locking system that requires the cup and blade assembly to be positioned correctly on the motor base before normal operation. Containers should not be forced into the locking mechanism.

Hot or boiling liquids should not be processed in the portable cups unless current manufacturer instructions specifically permit the intended temperature. Closed personal-blender vessels can develop pressure when hot contents are processed.

The cups should not be filled above their marked limits. Adequate liquid should be included when blending frozen fruit, leafy ingredients, ice, or other dense mixtures that require circulation around the blade.

The motor includes thermal protection. If the blender stops because of overheating, KOIOS directs users to unplug the appliance and allow approximately 15 to 30 minutes for cooling before trying again.

Technical Specifications

Product History

The BL337B became publicly available in 2023 as part of KOIOS’s compact personal-blender range. It combines a 900-watt maximum motor rating with portable blending cups and a twist-operated motor base.

The model has been offered in several color configurations, including Grey Blue, Sky Blue, and Silver. Package contents can also differ between production revisions, with later configurations containing three cups rather than the earlier two-cup arrangement documented for some BL337B packages.

KOIOS subsequently expanded its personal-blender range with models such as the BL319B, which uses updated cup and blade configurations. The BL337B remains identifiable through its specific model number, 900-watt rating, and compatible replacement components.

Compatibility

The BL337B is designed for cups, seals, lids, and blade components specifically documented for the KOIOS BL337B platform. Replacement components should be selected by model number rather than by visual appearance alone.

KOIOS 22- to 23-ounce replacement cups sold for compatible BL219B, BL328B, BL337B, and selected related models have been documented as cross-compatible. Exact thread and blade compatibility should still be checked before use.

The detachable blade assembly should be used only with a compatible KOIOS cup and correctly fitted sealing ring. An incorrect cup, seal, or blade assembly can prevent proper locking or cause leakage.

The appliance is a corded personal blender and requires compatible household AC electrical service. It is not a rechargeable or cordless portable blender.

Frequently Asked Questions

What is the exact KOIOS model?

This product is the KOIOS BL337B personal smoothie blender in the Grey Blue color configuration.

How many cups are included?

This configuration includes three cups: two 23-ounce portable cups and one 17-ounce cup.

Is the BL337B cordless?

No. It is a corded AC appliance and requires an electrical outlet during blending.

How is the blender operated?

The cup is filled, fitted with the blade assembly, inverted, and locked onto the motor base. Twisting the installed cup engages the blending mechanism.

Does it have several speed settings?

No. The BL337B uses a single operating speed rather than a multi-speed electronic control panel.

Can the BL337B make smoothies?

Yes. Fruit smoothies, protein shakes, and similar cold blended beverages are among the model’s primary intended uses.

Can it process frozen fruit?

Yes. Frozen fruit can be processed when pieces are appropriately sized and enough liquid is included to support circulation around the blades.

Can it crush ice?

Yes. The 900-watt motor and six-leaf blade are documented for ice crushing and frozen-drink preparation in suitable quantities.

What happens if the blender overheats?

The thermal protection system can stop the motor. KOIOS advises unplugging the appliance and allowing it to cool for approximately 15 to 30 minutes before restarting.

Are the cups BPA-free?

Yes. KOIOS identifies the supplied portable cups as BPA-free.

Are the cups dishwasher safe?

Yes. The cups and lids are documented as dishwasher safe.

Can the motor base go in the dishwasher?

No. The electrical motor base should be cleaned by wiping its exterior and must not be submerged or machine washed.

Can drinks be stored in the cups?

Yes. A flat storage lid and drinking lids are included for compatible cups after the blade assembly has been removed.

What are the lip rings for?

The lip rings attach to compatible cups after blending to provide a smoother drinking edge when a user drinks directly from the container.

Why will the blender not start?

The cup and blade assembly may not be locked correctly onto the motor base. The BL337B includes a safety mechanism that prevents normal operation when the components are not properly installed.

Why might the blender leak?

Leakage can occur if a sealing ring is missing, displaced, worn, dirty, or installed incorrectly. The cup and blade assembly should also be tightened correctly before use.

Do older BL337B packages contain the same accessories?

Not necessarily. Earlier product documentation shows some two-cup configurations, while this specific configuration includes three cups. Package contents should therefore be checked against the individual product identifier.

Does the blender require installation?

No permanent installation is required. The appliance should be placed on a stable surface, connected to compatible electrical power, and assembled according to the operating instructions.

What warranty applies?

The BL337B is documented with a two-year limited warranty. Coverage requirements and exclusions are governed by KOIOS’s applicable warranty terms.

Buying Considerations

This configuration should be distinguished from earlier BL337B packages that contained two cups. The version represented here contains two 23-ounce cups plus one 17-ounce cup.

The appliance uses twist operation rather than dedicated electronic speed buttons. Users who require multiple selectable speeds or programmed blending cycles should account for this simpler control system.

The motor rating is described as a maximum or peak 900-watt specification. Peak motor power should not automatically be treated as equivalent to continuous electrical consumption.

The BL337B is a personal blender rather than a large-batch countertop system. Its cups are designed for individual drinks and smaller food preparations rather than family-size quantities.

Replacement cups, blades, and sealing rings should be selected by model compatibility. Small differences in threads and drive geometry can make visually similar blender parts unsuitable.

Customer Feedback Summary

This section is a generalized summary of recurring themes reported in publicly available customer feedback and does not represent verified product specifications. Positive feedback frequently focuses on the compact motor base, strong blending performance for its size, straightforward twist operation, and convenience of the portable cups.

Customers commonly describe smoothies, protein shakes, frozen fruit drinks, and crushed-ice beverages as practical uses for the BL337B. The multiple cups and drinking lids are also frequently mentioned by households where more than one person prepares individual drinks.

Reported limitations include operating noise and the need to use enough liquid when processing frozen or fibrous ingredients. Dense mixtures can occasionally require stopping the motor, shaking or repositioning the cup, and restarting the blend.

Some long-term feedback mentions wear involving seals, blade assemblies, locking tabs, or motor components. Leakage complaints are also reported when sealing rings become displaced or worn. These experiences vary with assembly, cleaning, ingredient load, and frequency of operation.
