-10% SalePortable 256Wh LiFePO4 power station delivering 300W pure sine output, 60-minute AC recharging, and 10-year daily battery reliability.
The EcoFlow RIVER 2 is an ultra-compact portable power station engineered to resolve immediate power outages, field energy demands, and mobile workstation requirements. Built around industrial-grade Lithium Iron Phosphate (LiFePO4) cell chemistry, this unit delivers 256Wh of energy storage and continuous 300W pure sine wave AC output. It bridges the gap between bulky emergency generators and small pocket power banks, giving users an independent, silent power source capable of running critical electronics during Bangladesh's frequent grid load shedding or off-grid field operations. Designed for long-term daily cycling, the internal Battery Management System (BMS) continuously regulates voltage, current, and temperature across every individual cell. Unlike older ternary lithium units that degrade after 500 cycles, the RIVER 2 sustains over 3,000 full charge-discharge cycles while retaining at least 80% of its original capacity. It features high-speed bidirectional inverter architecture, enabling a complete 0 to 100% recharge in 60 minutes via standard 220V grid wall outlets.
Zener Authenticity Promise: All sitemarks, models, and technical statistics are registered with the factory and verified in our physical laboratory before sale.
Engineered with LiFePO4 cells rated for 3,000+ cycles at 80%+ depth of discharge, translating to nearly 10 years of daily continuous use under standard conditions
Bidirectional charging circuit draws up to 360W from AC mains, completing a 0-100% full recharge in 60 minutes without requiring an external AC brick adapter
Built-in algorithm permits continuous operation of resistive heating devices and electronics up to 600W by lowering output voltage, preventing circuit breaker cut-offs
Automatic transfer switch detects mains failure and transitions to internal battery power in under 30 milliseconds, preventing modems, routers, desktop PCs, and CPAP machines from resetting
High-efficiency heat sinking and internal cooling fan profiles keep acoustic emissions under 30 dB during standard operation
To maximize LiFePO4 battery health during prolonged storage, discharge the unit to 60%, store in a dry environment between 15°C and 25°C, and complete a top-up cycle every 3 months.
When charging via solar panels, verify that the open-circuit voltage (Voc) of the solar array does not exceed 30V DC to prevent overvoltage protection triggering on the MPPT controller
For continuous desktop UPS/EPS operation, connect the RIVER 2 to the wall outlet and limit charging speed to 150W in the EcoFlow app to minimize thermal fan cycling and maximize operational life
Keep at least 10 cm of clearance on both side vents during operation so the thermal cooling fan can dissipate internal heat freely under high loads
No, the EcoFlow RIVER 2 cannot start high-surge inductive loads like full-sized compressors or 1500W heating elements because its continuous limit is 300W (with 600W X-Boost)[2][3]. It is specifically engineered to power low-to-medium wattage electronics such as laptops, mini-coolers, Wi-Fi routers, televisions, studio lights, and CPAP machines
The EcoFlow RIVER 2 will power a standard 10W Wi-Fi router and ONU for approximately 18 to 22 hours continuously, or recharge a 60Wh laptop battery 3 to 4 times on a single charge. Runtime is calculated as: 256Wh × 0.85 (inverter efficiency) ÷ Total Load Wattage.
Yes, the EcoFlow RIVER 2 supports pass-through charging and acts as an Emergency Power Supply (EPS) with a sub-30ms switchover time[5]. When connected to an AC outlet, incoming utility grid power bypasses the battery to directly feed connected devices, switching automatically to internal battery power when mains fail
Any 12V or 18V solar panel outputting within 11V to 30V DC and up to 8A (110W Max) is compatible with the RIVER 2 using an XT60 solar charge cable. Under clear sunlight, a 110W portable solar panel recharges the 256Wh battery from 0% to 100% in approximately 3 to 4 hours
LiFePO4 chemistry provides up to 3,000 full charge-discharge cycles before dropping to 80% capacity, lasting 6 times longer than conventional lithium-ion batteries which degrade after 500 cycles[2][3]. LiFePO4 is also thermally and chemically stable, reducing thermal runaway risks even in ambient operating temperatures up to 45°C
