Mini Magnetic Stirrer, USB‑Charged Portable Liquid Mixer, Adjustable Speed 200‑2000 RPM, 1.0‑1.5L Capacity, Low‑Voltage Lab Magnetic Mixing Equipment

This portable mini magnetic stirrer is a compact‑sized liquid mixing device designed for both laboratory and daily‑use sample stirring jobs. With a maximum stirring capacity of 1.0‑1.5L, it delivers stable and uniform liquid agitation without requiring heating function, perfectly suited for mixing reagents, culture solutions, pigments, essential oils, coffee, supplements and other water‑based liquids.

Equipped with a built‑in 3.7V rechargeable lithium‑ion battery and 5V USB charging port, this magnetic mixer brings you dual power‑supply flexibility. You can operate it wirelessly after a full charge, or keep it running continuously while plugged into a USB power adapter, power‑bank, laptop or car charger. Low‑voltage DC motor design greatly improves operation safety, letting you work without worries of electric‑shock risks.

The rotation speed can be smoothly adjusted from 200 RPM up to 2000 RPM via the front‑mounted rotary knob. You can easily fine‑tune stirring speed to match different viscosity levels of your liquids. Its soft‑start magnetic driving system prevents sudden high‑speed rotation, effectively stopping liquid splashing and sample waste. The hidden magnetic driving core runs quietly with little vibration during long‑time continuous stirring.

Thanks to its lightweight square‑shaped compact body, this USB magnetic stirrer takes up very little workspace. You can easily carry it between lab benches, home workstations, classrooms or outdoor testing locations. The smooth, stain‑resistant top panel can be simply wiped clean after use. An excellent low‑cost stirring alternative for small‑scale biochemical experiments, hobby pigment mixing, household solution preparation and teaching demonstration tasks.
