Unbeatable Solar Panel Durability Unlike other products in its price range, Sun KingTM Pro 2 uses a detachable solar panel with a repairable junction box, and a five-meter cable. The 3.3-watt, aluminium-framed, industrial-grade glass protected solar panel is far more durable than alternatives based on polycarbonate or epoxy encapsulation, both of which degrade quickly in harsh environments.

Bright Home Lighting 

Dual Smart Phone Charging
With its 150-lumen, warm-temperature LED light, Sun KingTM Pro 2 yields an astounding amount of light from a single sunny day of solar charging, without expensive kerosene or the carcinogenic fumes that accompany it. Users can enjoy up to 6 full hours of in the Pro 2's brightest mode to increase productivity during the night, or they can opt for up to 36 hours of light in lower power modes. The Sun King Pro 2 is an ideal light for the entire family: it can be hung above to light a room, placed on a desk for reading or easily carried by hand.

Real-time LED Display 

Sun KingTM Pro 2's LED displays the amount of battery power remaining in an easy to read standard battery indicator. 

Innovative Charge Power Feedback Poor charge performance due to improper panel placement remains the biggest source of disappointment for solar home lighting customers. When users charge Sun KingTM Pro 2, the LED Meter indicates the solar charging power instantly, on a scale of 1 to 5, allowing even solar novices to easily understand and optimize panel placement, becoming masters of their technology. This feature drastically improves user satisfaction. 

Breakthrough Longevity
Drop it, stomp it, or splash it. From its water-sealed, nearly unbreakable polycarbonate shell, to its dust cover-protected charging ports, to its industrial-grade, aluminium-framed solar panel and durable steel stand, Sun KingTM Pro 2 is built to last in tough environments. Its longer-lasting, quality-tested components set the gold standard for product lifetime.

Revolutionary Batteries
Sun KingTM Pro 2 uses a revolutionary Lithium Ferro-Phosphate(LFP) battery. Efficient, stable, and ultra-long-lasting, LFP is far superior to even lithium-ion batteries (which themselves outperformed the old NIMH NiCad, & lead-acid batteries), making it a leader in the solar light industry.
