The EcoFlow RIVER 3 Max is the direct successor of the RIVER 2 Max, with a bigger 572 Wh LiFePO4 core and one extra AC socket for a total of three Type F outlets. At 8 kg and 23.4 x 22.4 x 25.6 cm, it sits between a tabletop station and a full DELTA, delivering 600 W of combined AC power with a 1,200 W peak, and can run up to eight devices simultaneously.

• 572 Wh LiFePO4 (LFP) core with 3,000 cycles to 80% capacity for a long service life.
• Three Type F outlets combined 600 W, 1,200 W peak, pure sine wave for laptops and mixers.
• 140 W USB-C plus two 12 W USB-A ports keep phones and cameras topped up alongside AC gear.
• Solar input up to 220 W via XT60 (11-55 V), a 220 W panel can refill it in roughly 1.4-2.8 hours in good conditions.
• UPS switchover in under 10 ms protects sensitive electronics during grid dips.
• Wi-Fi, Bluetooth and USB-B for the EcoFlow Power Manager plus 5-year warranty.

An easy pick for camper vans, holiday-house weekends or a home-office UPS that also has to cover a couple of lights and a small fridge on top of the IT gear. On the DC side the RIVER 3 Max offers a 12.6 V / 10 A car-charger output up to 126 W, useful for a cool box or a 12 V pump in a van conversion, and the 30 dB noise threshold at 300 W keeps the fan barely audible during light indoor use.
