Technology / product information

What kind of power source is truly essential during emergencies? One that can always be used, no matter the situation. The magnesium-air battery "Mg:air," developed by KEM (THAILAND) CO., LTD., generates electricity instantly with saltwater. With no fuel, charging, or preparation needed, it’s redefining emergency power across homes, shelters, and industries.

■ Emergency Power Without Charging or Fuel
Mg:air uses magnesium as the anode and air's oxygen as the cathode. When saline (saltwater) is added as the electrolyte, it activates instantly to generate electricity. Since no chemical reaction occurs during storage, it remains stable and maintenance-free until needed. Note: plain water does not provide proper activation.

■ Reliable and User-Friendly for Stockpiling
Mg:air can be stored up to 5 years without degradation. Weighing only around 350g, it’s lightweight and simple to use. Just inject saltwater to activate. Its USB output delivers enough power to fully charge one smartphone, making it an ideal emergency backup.

■ Designed for Thailand’s Disaster Risks
Frequent power outages in Thailand due to floods, storms, or infrastructure issues demand accessible and safe power solutions. Mg:air offers immediate electricity without relying on fuel supplies or complex equipment. It’s perfect for homes, hospitals, and evacuation centers across the country.

■ Why Mg:air Redefines Emergency Power
- No charging or fuel—activates instantly with saltwater
- Capacity to fully charge one smartphone
