Greenlight Planet’s Sun King™ Pro 400 is the industry’s new gold-standard phone-charging solar lantern. Compared to the incumbent Sun King Pro 2 that it replaces, Sun King™ Pro 400 packs nearly double the battery storage and double the solar panel power, offering twice the phone charging capacity of its predecessor. And with the latest high-efficiency LEDs, it shines 40X brighter than kerosene, at 400 lumens, drawing favorable comparisons with AC electric lamps. Despite its high performance and premium build quality, the Sun King™ Pro 400 comes at a remarkably affordable price. Get things done, at home or at work, day and night, with our most powerful lantern yet.
