Arkpax

The power station that goes where others can't.

Reserve Power Co. is proud to carry Arkpax — the only portable power brand to hold an IP67 waterproof and dustproof rating across its lineup. 

Where other power stations require shelter, Arkpax is built to take the hit. IP67 certification means full protection against dust and sustained immersion in up to one meter of water, engineered for environments where most power stations simply fail. Every unit delivers pure sine wave output safe for sensitive electronics, charges in under 2.5 hours via AC, and supports solar input for off-grid recharging. 

Arkpax systems are built on LiFePO₄ chemistry for long cycle life and thermal stability, with UPS bypass mode for seamless home backup and a switchover time under 10ms. The flagship Ark PRO expands from 2.3kWh to over 25kWh with stacked extra batteries; purpose-built for multi-day off-grid setups, marine environments, construction sites, and emergency response.

The lineup spans from the compact Ark NOA 600W for everyday carry to the Ark PRO 2400W and rugged Titan 1200W for high-demand use in extreme conditions. Each system supports multiple recharge paths: AC wall power, solar, or car — or a combination.
