Waterproof and Submersible Floating Case: IP67 military grade construction protects your power source from water, dust, shock, and harsh environments, so you stay operational no matter the conditions.

High Output Inverter System: 2,000W continuous and 4,000W peak output with AC outlets and USB C PD60W ports allows you to run tools, electronics, and appliances anywhere.

Cold Weather Ready Technology: Internal heating system ensures reliable performance and safe charging down to -20°F, eliminating the failures common with standard lithium batteries.

Field Serviceable Modular Design: Removable electronics tray and accessible components allow quick repairs and maintenance in remote locations, minimizing downtime when support is far away.

Lightweight and Buoyant Construction: At less than half the weight of traditional lead acid batteries and fully buoyant, it is easier to transport, safer to handle, and ideal for marine and off grid use.
