As shown in the images, the LED magnifier features sleek and compact design, and comes with a 5x magnification lens in order that you can use it to read text, review photos or check devices at five times magnification, and simply pressing down the LED magnifier you can activate built-in 3 LED lights, which provides steady and bright light for viewing. Apart from that, the LED magnifier is powered by two lithium ion batteries.
