Double-sided magnifying makeup mirror: The 1x magnification side is designed for full-face makeup application and overall look assessment, while the 30x magnification side is ideal for detailed grooming—such as tweezing stray hairs, applying eyelash extensions, examining blackheads, and checking skin texture or fine lines. The optimal viewing distance is 2 inches (approx. 5 cm); the image will appear inverted when viewed too close to the mirror, which is a normal physical phenomenon. Touch controls: Tap to turn on and cycle through cool, warm, and natural light modes, or tap again to turn off; double-tap to turn off immediately. The mirror features a memory function that retains your last light color and brightness settings; long-press to adjust brightness (1% to 100%), and it includes a 30-minute auto-off function. It houses a built-in 5000mAh rechargeable battery providing approximately 15 days of continuous use and charges via a side Type-C port. The 30x magnification side is particularly beneficial for users with poor eyesight, facilitating precise eyebrow grooming, makeup application, and contact lens insertion. Please charge before first use. Weight: 3.17 lbs.
