Portable power stations have become a practical addition to residential outdoor power equipment, but the range of options can be confusing when capacity, output, condition, and price all vary. The four EcoFlow models here cover a wide spectrum-from a 256Wh unit built for small electronics to a 1024Wh station that can handle more demanding equipment. What separates them isn't just power; it's how each unit balances capacity, output, and whether it's new or refurbished.
Quick Take
If you're looking for a compact unit to keep phones, lights, and small appliances running, the EcoFlow RIVER 2 is the most accessible entry point. The RIVER 2 Pro adds considerably more capacity and output in a still-portable package. The RIVER Pro is the only new-condition model in the set, while the DELTA 3 Plus is the big one, with the highest capacity, the highest AC output, and the most outlets.

Product Notes
EcoFlow RIVER 2 Portable Power Station 256Wh Generator LFP Certified Refurbished
Starting at 256Wh, this is the smallest battery in the lineup. The 300W AC output (600W surge) is enough for phones, tablets, small fans, and lights, and the certified refurbished condition keeps the price entry-level. It supports AC wall charging, 12V car charging, and solar input, so you have flexible ways to top it up. The limitation is the capacity: 256Wh will not carry high-wattage tools or a large fridge, so treat this as an essentials-and-short-outage companion rather than a whole-home power source.
EcoFlow RIVER 2 Pro 768Wh Portable Power Station LFP Generator Refurbished
The RIVER 2 Pro jumps to 768Wh and 800W AC output (1600W surge), which broadens the list of appliances you can run. You get 11 outlets, including AC, USB-C, and other ports, and the LFP battery is designed for long cycle life. Because it's listed in very-good refurbished condition, it may have visible scratches or dents and could come without original packaging or accessories. Weigh that cosmetic uncertainty against the capacity jump-if you're comfortable with it, this model bridges the gap between the entry-level RIVER 2 and the higher-output DELTA series.
EcoFlow RIVER Pro Power Station 720Wh Generator for Outdoor, Camping, RV
The RIVER Pro is the only new-condition product in this comparison, so it will appeal if you want a pristine, unopened unit. It packs 720Wh capacity and 600W AC output (1200W surge) across two AC outlets, and it can power up to nine devices at once with its mix of ports. The catch is that its capacity is slightly below the RIVER 2 Pro's 768Wh, and its output is lower than both the RIVER 2 Pro and the DELTA 3 Plus. For RV and outdoor uses with moderate power demands, the new condition and straightforward design make it a solid pick.
EcoFlow DELTA 3 Plus 1024Wh 1800W Portable Power Station LFP Battery Refurbished
The DELTA 3 Plus takes over as the largest and most powerful model here: 1024Wh capacity, 1800W AC output (3600W surge), and six AC outlets. It also features 1500W AC charging for quick top-ups, and the LFP battery is built for a long service life. It's listed as certified refurbished, so you're getting a restored unit rather than a new one. The main trade-off is scale: this amount of capacity and output is more than you need if your only goal is recharging a phone and a few lights, and it comes with the highest listed price in the group.
Final Recommendations
If you want the most run time for a range of home and camping loads without going to the top price, the EcoFlow RIVER 2 Pro at $309.00 is the balanced pick. If you need the maximum power and capacity here and are comfortable with certified refurbished gear, the EcoFlow DELTA 3 Plus at $598.75 is the one to choose. For a lightweight, low-cost way to keep essential devices charged, the EcoFlow RIVER 2 at $161.25 gets the job done. If you prefer a new-condition unit for RV or outdoor use, the EcoFlow RIVER Pro at $448.75 is the straightforward choice.
