EcoFlow RIVER 3 MAX PLUS Wireless, 858Wh

The EcoFlow RIVER 3 Max Plus Wireless is a portable battery power station combining a total capacity of 858 Wh (286 Wh integrated + 572 Wh additional battery) with a RAPID 5,000 mAh magnetic power bank for wireless and USB-C/A charging. The unit uses X‑GaNPower technology for fast charging and delivers up to 600 W continuous AC output (X‑Boost up to 1,200 W). A built‑in professional UPS with a switching time of up to 10 ms preserves continuity for sensitive equipment while quiet operation below 30 dB supports use in noise‑sensitive environments. The station can be charged from mains, car socket or solar panels and is controllable via the EcoFlow app over Wi‑Fi or Bluetooth.

Advantages

The RIVER 3 Max Plus Wireless offers a compact form factor with modular capacity, enabling extended runtime by adding the auxiliary battery. Fast multi‑input charging (AC, car, solar) and X‑GaNPower reduce downtime. A pure sine wave AC output and UPS function protect and maintain power to sensitive electronics. The included RAPID magnetic power bank provides Qi2 wireless charging, PD 3.0 USB‑C output and a built‑in stand for convenient on‑the‑go use.

Key specifications

How to use

Place the RIVER 3 Max Plus on a stable, ventilated surface and connect input sources as needed: mains AC for fastest recharge, solar panels via the solar input for off‑grid charging, or the car socket for mobile recharging. Use the AC outlets, USB‑C/A ports or DC output to power devices. The RAPID magnetic power bank attaches to compatible phones for wireless charging or can be used via its USB‑C connector. Monitor charge status, change settings and start or stop charging from the EcoFlow app over Wi‑Fi or Bluetooth. Observe ambient temperature limits when charging or discharging to ensure safe operation.

Recommendations

For longest battery life, store and operate the unit within recommended temperature ranges, avoid deep discharge when possible, and use the EcoFlow app to monitor cycles and firmware updates. When charging from solar, use panels that match the 11–55 V and 220 W input range; when powering sensitive electronics, connect them to the AC outlets to benefit from the pure sine wave output and UPS protection.
