61% off/From $259

EcoFlow has launched an RV Season Sale with up to 61% discounts across an array of power solutions for your upcoming travels and adventures – plus, continuing FREE gifts on purchases over $600. Among the lineup, we spotted a particularly notable deal on the more compact EcoFlow RIVER 3 Plus Portable Power Station with an EB600 extra battery (AKA RIVER 3 Max Plus) and 220W solar panel for $499 shipped, which is not an offered bundle over at Amazon. Normally $948 at full price, we don’t often see this expanded pairing joined by a solar panel, with the station and battery currently at its $359 low (matching at Amazon), while the 220W solar panel is cheapest at Amazon for $299 – meaning you’d be paying $159 more buying things separately. The deal here gives you a 47% markdown off the going rate for $449 savings at the lowest price we have tracked. Head below to browse the full rundown of deals while this sale lasts.

Instead of starting at the RIVER 3 Plus power station’s 286Wh LiFePO4 capacity, this expanded bundle gives you the maximum 858Wh battery capacity alongside a 220W solar panel, which provides the maximum solar-charging input for the unit. This is a more compact power solution with eight output ports (3x ACs, 2x USB-Cs, 2x USB-As, and a car port), thanks to the added ports from the battery. This setup provides devices and small appliances with up to 600W of steady power and can surge up to 1,200W. Alongside the maximum solar charging input you can utilize with this bundle, there are also options to recharge from a standard AC outlet, a gas generator, or the car port while driving.

***Note: As I mentioned, EcoFlow is continuing its FREE gift offers from the previous Mother’s Day Sale, with orders over $600 getting a FREE 45W solar panel, while orders over $3,000 get two FREE 160W solar panels. Some of the following deals also get extra savings taken off automatically in your cart, so don’t be surprised if some pricing on the landing pages do not initially match up.
