Adjustable Brightness

If you need powerfully bright illumination right away, you can set your Pro 400 to its Turbo Mode for five hours of bright, 400-lumen light. To conserve power and make the most of a single charge, its Normal Mode features twelve hours at 100 lumens, and its Low Power Mode for up to a hundred hours at 25 lumens.

Smart Mobile Charging

The Pro 400 features a universal, 5-volt USB port and is equipped with several phone adapters, so you can charge practically any type of mobile phone with solar power.

Extensive Battery Life

Even with daily use and charging, the Pro 400 battery typically lasts five years, a 50% improvement over previous Sun King lanterns.
