A rechargeable juicer, often called a portable blender or USB juicer, is a compact, battery-powered device designed for making fresh juices, smoothies, and shakes on the go. Unlike traditional countertop juicers, these are cordless, lightweight (typically under 1 lb), and rechargeable via USB, making them ideal for travel, office use, workouts, or quick home prep. They usually feature 4-6 stainless steel blades, a 300-500ml capacity cup, and a built-in lithium-ion battery that lasts for 10-20 blends per charge. Most models blend rather than extract pure juice (like masticating juicers), so you'll get a smoothie-like result with some pulp.
