Extra battery EcoFlow WAVE 3  is a portable energy solution designed to power your EcoFlow WAVE 3 portable air conditioner, providing climate comfort on the go without the need to use an external power source. With a capacity of1024 Wh·h and a high-quality LiFePO4 (Lithium Iron Phosphate) battery, this battery offers exceptional durability, retaining 80% capacity after 4000 cycles, which is equivalent to approximately 10 years of daily use. Designed to be detachable  easy to transport, it easily integrates with the WAVE 3, adding up to 8 hours of battery life in Eco mode, perfect for camping, RVs, boats, or any off-grid scenario where thermal comfort is needed.

One of the main advantages of the battery is its ultra-fast charging. Using a combination of AC and solar charging, it can be fully charged in just 75 minutes with a maximum output of 1000W. It supports multiple charging options including solar panels up to 400W (full charge in about 3-7 hours depending on conditions), EcoFlow generator charger (charge in 1 hour drive), car outlet (12V/24V) or standard AC outlet via port XT150 (charging in 2 hours). In an emergency, the XT60 port allows for slower charging in about 10 hours. This versatility makes the battery suitable for any situation, from traveling to camping adventures. The battery must be connected to the WAVE 3 for charging as it cannot be charged by itself.

The additional battery has USB-A and USB-C ports, allowing you to charge devices such as smartphones, tablets or other USB accessories, turning WAVE 3 into a small portable powerhouse. Detachable design makes it easy to transport and store, it weighs around 9.7kg (total around 25kg combined with WAVE 3). The rugged design is IP65-rated for dust and water resistance, making it suitable for harsh outdoor environments such as camping in wet or dusty environments. In addition, the battery has a flame retardant coating and withstands a drop from 1.5 m, ensuring reliability under intensive use. Intelligent control is supported by the EcoFlow application, which uses Wi-Fi and Bluetooth connections to monitor battery status in real time, including charge level, operating time, which remaining, and WAVE 3 maintenance notifications, such as emptying the water tank. The application also allows you to adjust the operation modes of the air conditioner (Max, Eco, Sleep, Pet Care) and set automatic shutdown timers, improving energy efficiency. The battery supports Eco WAVE 3 mode, which intelligently alternates cooling and ventilation to maximize operating time up to 8 hours compared to 2-3 hours in Max mode. X-GaNPower technology reduces heat loss during charging, ensuring quiet operation and optimal energy efficiency.

The additional battery is designed to ensure environmental friendliness. The choice of LiFePO4 chemistry not only provides a long life, but is also safer and more stable than the NCM batteries used in previous models such as the WAVE 2, which only offered 800 cycles. In addition, WAVE 3 uses environmentally friendly refrigerant R290, which reduces CO₂ emissions to 2,040 kg over 10 years, which is equivalent to saving 130 trees. The battery is covered by a 2-year limited warranty, separate from the WAVE 3 warranty, and offers over 40 security measures based on a cloud monitoring algorithm to protect against overloads, overheating and short circuits.

Thus, EcoFlow WAVE 3 additional battery  is a powerful and versatile solution to extend the autonomy of the WAVE 3 portable air conditioner, offering portability, fast charging and exceptional durability. With its rugged design, compatibility with multiple charging sources and smart features via the app, it's the perfect choice for those looking for climate comfort in camping, RVing or any autonomous scenario, without compromising on sustainability or convenience.
