EcoFlow River 3 Max Plus Portable Power Station 858 Wh 600 W Black/Grey

The EcoFlow River 3 Max Plus is a portable power station designed for off-grid use and home emergency backup. It uses an 858 Wh lithium iron phosphate (LiFePO4) battery to power essential electronics. The unit provides 600 W of continuous output, enough to operate several small appliances at once. Two AC outlets allow users to connect household equipment as they would to a standard wall socket. The system can be recharged via AC mains, a vehicle’s 12V socket, solar panels, or USB.

In addition to AC outlets, the power station offers several DC connections. The front panel includes three USB-A ports and one USB-C port for mobile devices. Two DC outputs and a 12V socket support camping equipment. Wi-Fi and Bluetooth connectivity allow for remote monitoring via the mobile app. An IP54 rating ensures the enclosure is resistant to dust and splashing water.

The unit is designed for portability, weighing 4.7 kg and measuring 234 × 232 × 146 mm, which makes it easy to store in a vehicle. Integrated handles allow it to be moved between locations, while an onboard display shows battery status and current power output. The device operates at a quiet 30 dB.
