Battery & Power Draw: The Hybrid 5328's 2200mAh battery is twice the capacity of the Basic 5329, yet provides less than half the runtime — reflecting the significant energy demand of the TEC module, which can draw up to 7W vs the Basic's 2W ceiling.
Physical Profile: The Hybrid adds thickness to accommodate the TEC module and larger battery. The 27.5g weight difference is noticeable for handheld shooting but minimal for rigged setups.
Intelligent Control: The Hybrid 5328 introduces Auto mode that dynamically adjusts cooling output based on thermal load, while the Basic 5329 offers manual High/Low settings only.

Both models incorporate comprehensive protection mechanisms:Overvoltage Protection: Prevents damage from power input fluctuationsOvercurrent Protection: Limits current draw to safe levelsOverheating Protection: Monitors internal temperature and reduces output or shuts down if thermal limits are exceededFan Malfunction Alert: Visual indication if the cooling fan fails to operate correctlyHybrid 5328 Exclusive: The TEC-equipped model includes an additional condensation warning—users should avoid running the cooler when the camera is powered off to prevent potential moisture buildup inside the camera body.Universal CompatibilityThe cooling system supports:

This positioning maximizes thermal contact while maintaining access to camera controls. After installation, the camera's LCD screen cannot be fully stowed. Remove the cooling fan before storing the LCD screen. Neither unit is waterproof—avoid humid environments.
