Carson LM-30 DESKBRIGHT 300 Magnifier
Key Features
  • 4.3" Main Lens
  • Aspheric Lens Reduces Distortion
  • 2x Magnification
  • 5x Spot Lens
The LM-30 DESKBRIGHT 300 Magnifier from Carson features a 4.3" main lens with 2x magnification, as well as a smaller 5x magnification spot lens for very fine print and details. A flexible goose neck allows you to position the magnifier where you need it, and four LED lights with a diffusive cover illuminate your subject. These light diffusers eliminate LED hot spots and evenly distribute the light, and the magnifier's aspheric lens provides a large viewing area while greatly reducing edge to edge distortion. The LM-30 is ideally suited as a reading aid for books, magazines, and newspapers, and this versatile hands-free magnifier works well for crafts, model building, soldering, jewelry design, needlepoint, sewing, quilting, coin and stamp collecting, and more. The light runs on AC power via a USB Type-C cable and wall adapter, but can also run on three AA batteries.

What are the power needs of this magnifier (so I can figure out what size USB power bank to buy)?
Asked by: Sarah
The Carson LM-30 DESKBRIGHT 300 Magnifier (B&H# CALM30) comes with an AC adapter included. Moreover, it can run on three AA batteries. Now, it requires 5VDC (through the USB C port) and would be able to be used for hours at a time with a 5,000mAh or 10,000mAh USB power bank such as the Belkin BoostCharge USB-C Power Bank (10,000mAh, 15W, White) (B&H# BEBPB011BTWH): https://bhpho.to/4bmSPLt
