EcoFlow WAVE 3 Portable Air Conditioner Battery 858W 1024Wh Black

This product is the extra battery for the EcoFlow WAVE 3 and is not a standalone air conditioner. It stores energy and supplies it to a compatible WAVE 3 unit through the designated system connection. The EcoFlow WAVE 3 portable air conditioner must be purchased or available separately.

The 1024Wh figure represents the battery's stored energy capacity, while 858W is the listed power rating. Actual air-conditioner runtime depends on the WAVE 3 operating mode, temperature setting, ambient heat, ventilation, compressor cycling and battery condition. UAE summer temperatures and cooling heavily exposed spaces can increase energy consumption and reduce runtime.

This extra battery is specified for the EcoFlow WAVE 3 system. It should not be assumed to work with earlier WAVE models, other portable air conditioners, power tools or third-party equipment, even if their voltage or connector appears similar. Confirm the model number EF-WAVE300-EB and the compatibility information before installation.

Place the WAVE 3 and battery on a stable, level and dry surface, switch the system off, and connect the battery using the manufacturer-specified cable and connection points. Ensure every connector is fully seated and that cables are not pinched, stretched or routed through standing water. After connection, power on the system and verify that the battery is detected through the unit display or EcoFlow monitoring system. Follow the current EcoFlow user manual for the exact connection sequence.

No separate inverter is normally required when the battery is connected directly to the compatible EcoFlow WAVE 3 system. Charging and discharging are coordinated through the integrated battery management system. Do not connect loads directly, modify the terminals or use an improvised inverter arrangement.

Yes, it can support temporary cooling in enclosed site offices, inspection cabins, security rooms, mobile workshops and other controlled work areas where fixed power is limited. It is not intended to cool an open construction zone or replace a correctly sized permanent HVAC system. Protect the battery from cement dust, metal debris, direct sunlight, water, impact and excessive heat, and comply with the project's electrical and fire-safety procedures.

It is suitable for camping, caravans and mobile outdoor setups when kept in a shaded, ventilated and dry location. Use the WAVE 3 in an enclosed or suitably ducted space for effective cooling, and avoid placing the battery directly on hot sand or inside a sealed vehicle. The unit should not be exposed to rain, irrigation spray, seawater or prolonged direct UAE sunlight.

High ambient temperatures increase the WAVE 3 cooling load and may reduce practical runtime compared with operation in milder conditions. Improve efficiency by shading the room or tent, closing openings, insulating exposed surfaces and starting cooling before the interior becomes extremely hot. Keep the battery itself within the operating temperature limits stated in the EcoFlow manual and allow it to cool before charging if the system reports excessive temperature.

The battery measures 516 × 281 × 111 mm and has a net weight of approximately 9.7 kg. Allow additional clearance for connectors, cable routing, ventilation and safe handling. For vehicle, caravan or site-cabin use, secure the battery against movement without covering ventilation areas or placing heavy construction materials on top of it.

The unit uses lithium iron phosphate, commonly called LFP or LiFePO4, battery chemistry. LFP cells are selected for stable operation and dependable performance through repeated charge cycles. The integrated battery management system coordinates charging, discharging and status monitoring, but users must still follow the manufacturer's temperature, storage and handling instructions.

Charge it only through the compatible EcoFlow WAVE 3 system and approved EcoFlow charging accessories. When connecting equipment to a UAE mains supply, use the correct UAE-compatible plug and a properly earthed 230V, 50Hz outlet installed in accordance with applicable local electrical requirements. Avoid overloaded extension leads, damaged cables, loose adapters and unapproved voltage converters.

Switch the system off, disconnect it as instructed by EcoFlow, and store the battery in a cool, dry and ventilated indoor area away from direct sunlight, moisture, combustible materials and metal objects that could damage connectors. Do not leave it for extended periods inside a parked vehicle or unconditioned site container during UAE summer heat. Check and maintain the storage charge at the intervals specified in the EcoFlow manual.

It is designed as a dedicated expansion battery for the EcoFlow WAVE 3 rather than as a general-purpose power station. It should not be used to operate drills, grinders, pumps, refrigerators or household appliances directly. Buyers requiring standard AC or DC outlets for tools and appliances should select a suitably rated portable power station instead.

Routine maintenance mainly involves keeping the casing and connectors clean and dry, inspecting cables for wear, monitoring battery status and installing manufacturer-issued firmware updates where applicable. Disconnect the system before cleaning and use a soft, dry cloth rather than solvents or pressure washing. Stop using the battery if it becomes swollen, cracked, unusually hot, wet or physically damaged, and arrange inspection through an authorised service channel.
