Product Features

Plug-and-Play Integrated Power System

The battery slides directly into the Glacier unit’s internal bay, enabling instant installation without external wiring. This seamless integration supports true wire-free refrigeration and simplifies setup during travel or outdoor use.

Extended Cooling and Freezing Runtime

With a 298Wh capacity, the battery delivers up to 40 hours of cooling or up to 19 hours of freezing in Eco mode. This makes it suitable for extended off-grid trips where continuous power access is limited.

Multi-Source Fast Charging Capability

The battery supports AC wall charging, vehicle charging, and solar input up to 240W. Under optimal conditions, it can fully recharge in approximately 2 to 2.5 hours, ensuring minimal downtime during travel.

100W Bi-Directional USB-C Power Output

The integrated USB-C port functions as both an input and output, delivering up to 100W of power. This allows the battery to charge laptops, smartphones, and other devices, effectively turning it into a portable power bank.

High-Cycle Lithium Energy System

Designed for long-term reliability, the battery supports up to 800 charge cycles while maintaining at least 80 percent capacity. Certain lithium iron phosphate variants offer even higher cycle durability exceeding 3,000 cycles.

Wide Operating Temperature Range

The battery is engineered to perform in extreme environments, operating between -20°C and 50°C for discharge and 0°C to 45°C for charging. This ensures stability in both hot and cold outdoor conditions.
