Amazon is currently offering the EcoFlow 572Wh RIVER 3 Plus with Extra Battery 300 back down at $319 shipped, which beats out the brand’s direct website pricing that has it keeping to the full $499 rate. Since mid-July, it’s been bouncing between $499, $399, and gone as low as $319 in 2026 here, while the direct website’s Prime Day Sale in June saw it fall to $303. You’ll be getting a $180 markdown with this deal, landing it back at the lowest price we have tracked at Amazon. You can also check out the full Home Preparedness Month Sale lineup here, which is offering up to 50% discounts and bonus extra savings, too.
This RIVER 3 Plus power station bundle (also known as the RIVER 3 Max) starts you off at a 572Wh LiFePO4 capacity rather than the RIVER 3 Plus’ 286Wh capacity – plus, it can further expand up to its maximum 840Wh capacity by switching the EB300 with the EB600.
It’s a setup that is ready to cover your personal devices and small appliances anywhere through the seven output ports (3x ACs, 2x USB-As, and a high-speed USB-C port), which deliver up to 600W of steady power supply and can surge up to 1,200W. You’ll have four options for recharging it, starting with the usual AC outlet plug-in, or you can do so from a gas generator, with up to 220W of solar panel input, or while you drive from a 12V vehicle auxiliary port.
Like I said, if you’re looking for another backup power solution, you’ll want to check out EcoFlow’s current Home Preparedness Month Sale with up to 50% power station discounts and a bonus extra 5% savings code – all starting from $299. You can also find sales from other brands over in our dedicated power stations hub here.
