MaxLupe Portable has been upgraded to provide even greater functionality for people with low vision who need a larger screen in a portable package. Weighing in at just 24 ounces, MaxLupe still provides a 5.8" TFT screen to deliver a big, brilliant image. The improved lithium-ion battery delivers 3 hours of continuous use and with an optional, easily swappable battery, users can double that amount. Continuous magnification ranges from 6.5x to 25x in reading mode and 3x to 7x in writing mode. Writing mode, no completely integrated into the unit, is comfortable and ergonomic to use. With just two control buttons and an inclinable viewing screen for optimal ergonomic positioning, MaxLupe continues to be easy to use.
