Military-Grade Durability Reinvented
The RugKing series is engineered for extreme reliability in the harshest working and outdoor environments. Each device carries IP68 and IP69K certifications, ensuring complete dust protection, resistance to 2-meter submersion, and survivability against high-pressure, high-temperature water jets. The lineup also meets the Mil-std-810H military standard, providing proven resilience against shocks, drops, and severe environmental stress.

From industrial settings like sandblasting and mining to outdoor pursuits such as hiking and camping, the RugKing series is built to deliver uncompromising ruggedness.
