EcoFlow River 3 Plus

The EcoFlow River 3 Plus wins the Portability dimension outright across the entire lineup at 10.4 lb. To put that in context: it weighs less than a full hydration pack. You can sling it into a daypack, toss it in a backpack camping bag, or carry it between car and campsite in one trip with room to spare. For the buyer who wants to get into LFP power without a large upfront commitment — or who needs a dedicated, ultralight camping station — the River 3 Plus is the entry point. At 286 Wh rated capacity (roughly 243 Wh usable) the honest scope is clear: this will keep phones charged for days, run a CPAP through a night or two, power a camp lantern, maintain a small fan, and provide emergency phone and medical device backup. It will not run a refrigerator or a window AC — the 600W continuous output and 1,200W surge are sized for small appliances only. EcoFlow's X-Boost mode extends its effective range by allowing it to power some appliances rated up to 1,200W through intelligent draw management. The expandability is the key feature that lifts the River 3 Plus above other ultralight options. Pairing it with an EcoFlow EB300 or EB600 extra battery pushes total capacity to 858 Wh — enough for serious multi-day camping use or light home backup coverage. The 60-minute full AC recharge is fast, and the 220W solar input lets a compact panel array refill it in a couple of hours. The three AC outlets, three USB ports, and one car port across seven total outputs cover standard camping needs. The 10ms UPS switchover keeps connected devices online during brief power interruptions. At $259 (MSRP $299) with a 5-year warranty and 3,000 LFP cycles to 80%, the River 3 Plus is the most affordable entry to LFP technology on this list.
