Energy Efficiency and Eco-Friendliness

Zero Breeze Max outputs 550 Watts, featuring Type-C (100W) and Type-A QC30 (18W) ports with an output voltage of 38V – 58.8V. 

EcoFlow Wave 2 in cooling mode consumes up to 550W from the mains or 459W from the battery, varying based on room temperature and set target. In standard mode, it typically operates around 400W. Both models showcase energy efficiency, with Zero Breeze offering diverse port options, while EcoFlow Wave 2 dynamically adjusts power consumption based on environmental conditions, emphasizing efficiency in portable cooling solutions.

Battery and Charging Options

Zero Breeze Mark 3 introduces a distinct battery strategy, featuring a separate 1036Wh add-on battery, available for separate purchase. This auxiliary power unit requires 2.5 hours to charge fully and accepts both DC (12-75V) and AC (100-240V) inputs. Notably, it incorporates versatile Type-C (100W) and Type-A QC30 (18W) ports, enhancing its functionality.

On the other hand, EcoFlow Wave 2 takes a unique approach with a removable 1159Wh battery, fully rechargeable within a brief 2.5-hour timeframe. The battery pack goes beyond the cooling system, offering a USB-C port for device charging, along with two USB-A ports and a 12V DC socket. The Wave 2 further diversifies its charging options, supporting AC, DC, and solar inputs, contributing to a comprehensive and adaptable charging ecosystem. 

For optimal cooling or heating modes, the Wave 2 necessitates a power station, an AC supply, or the removable wave 2 add-on battery source that costs $900. If you intend to power the Wave2 directly through the solar panel or an external 48V battery bank, you will be limited to using only the fan mode, with control over the fan speed. Unfortunately, switching to any other operational modes is not possible.
