Tenring Lightweight Personal Smoothie Maker for Fresh Juices Anywhere 150 W Juicer  (USB Portable Blender Juicer – High-Powered Smoothie Maker | 1 Jar | Multicolor)

Power Range: Most USB portable blenders have a motor power range between 3.7V and 7.4V, typically providing between 10-20W. This is enough for blending soft ingredients but may struggle with tougher items. RPM (Revolutions Per Minute): The motor usually operates at around 15,000 to 22,000 RPM, which is lower than full-size blenders. Higher RPMs may handle ingredients better but may drain the battery faster. Battery-Powered: The motor is powered by a rechargeable battery, typically with a capacity between 1500mAh and 4000mAh, depending on the model. This allows for multiple uses per charge. Limitations: Due to lower power, USB portable blender motors are best for soft fruits, ice cubes, or small amounts of greens. Harder items (e.g., nuts) or large ice chunks may overwork the motor. Overheat Protection: Many models come with built-in overheat protection to prevent the motor from overheating during extended blending sessions. Compact Design: These motors are compact and lightweight, optimized for portability, making them less durable than larger, more powerful motors. Noise Level: USB portable blender motors tend to be quieter than traditional blenders but can still produce some noise, especially if blending denser ingredients. Run Time: Continuous blending is often limited to short bursts (around 20-30 seconds) to prevent overheating and prolong the motor’s life.
