Performance
The EcoFlow RIVER 3 delivers 300W continuous AC with 600W surge and X‑Boost up to 600W. That’s enough for most small devices—laptops, cameras, drones, routers, desk fans, LED lights, and many kitchen or camp essentials. You can power up to six devices at once thanks to dual AC outlets, multiple USB ports, and a 12V car socket. For outage readiness, its <20 ms UPS (emergency power supply) helps keep networking gear and small electronics running with minimal interruption.
Battery & Specs
At the heart is a LiFePO₄ pack rated for 3000 cycles to 80%, giving long service life for frequent use. The unit is engineered for quiet, continuous duty (<30 dB) and includes IP54 battery protection for an extra layer of resilience. Safety systems cover over‑current, over/under‑voltage, temperature, and short‑circuit scenarios.
Portability & Design
Weighing 7.8 lb and measuring 10 × 8.3 × 4.4 in, the EcoFlow RIVER 3 is easy to grab and go. EcoFlow’s GaN‑based design focus keeps it about 30% more compact than the industry average and helps reduce heat, fan noise, and overall bulk—great for van life, car camping, and apartment storage.
Charging Options
- AC Wall (X‑Stream): Up to 320W; 0–100% in ~60 minutes.
- Solar: Up to 110W (11–30V) with an estimated ~2.6 hr full charge in ideal sun.
- Car (12V): 100W input; ~2.8 hr to full while you drive.
- Generator: Similar to AC—~1 hour for a full recharge around 320W.
These four options make it simple to keep the EcoFlow RIVER 3 topped up at home, on the road, or off‑grid.
