New low/$303

As part of the ongoing EcoFlow Prime Encore Sale, you can currently get the best price to date on the RIVER 3 Max Portable Power Station bundle (RIVER 3 Plus + Extra Battery 300) down at $303.05 shipped, after using the code EFPDFAFF at checkout, beating out Amazon’s pricing by $16, but you do get a FREE $40 tool pegboard with a purchase there. Down from a $399 full price, we’ve been seeing it consistently discounted to $319 since the beginning of June, which happens to be the lowest price spotted at marketplaces like Amazon. With the bonus savings code, things are dipping lower for $96 combined savings and marking a new all-time low price. You can shop the brand’s larger power station units in the Prime Encore Sale here.

This EcoFlow bundle provides a RIVER 3 Max setup, which is the name for the RIVER 3 Plus power station with an Extra Battery 300, taking the station’s initial 286Wh LiFePO4 capacity and instead giving you a 572Wh capacity for your personal device powering needs.

It provides a steady stream of power up to 600W through the seven ports (3x ACs, 2x USB-As, and a high-speed USB-C port), and can surge higher up to 1,200W when needed. For such a compact solution, it brings along a solid array of four recharging options: standard AC outlet recharging, as well as the same input from a gas generator, while also having a max 220W solar panel input, or charging as you drive from a vehicle auxiliary port.

As I mentioned, this deal is part of the overall continuing Prime Day deals from EcoFlow’s extended sale here, just be sure to use the code EFPDFAFF wherever possible to guarantee the best prices. You can find even more from this and other brands in our dedicated power stations hub here.
