Choosing a portable power station for residential outdoor power equipment usually comes down to capacity, AC output, and listed price. The four EcoFlow stations here span a compact backup unit, a middle-capacity expandable option, and two DELTA 3 Plus listings at the top of the capacity range, with listed prices from $161.25 to $598.75.
Quick take
If your main need is topping up small devices on a short trip, the RIVER 2 is the smallest-capacity and lowest-listed-price option. If you want expandable capacity without going to the top of the price range, the RIVER 3 Plus with EB300 Extra Battery sits in the middle. If you need the most AC outlets and the highest AC output, the DELTA 3 Plus models are the strongest match.

EcoFlow 572Wh River 3 Plus Portable Power Station with EB300 Extra Battery
The RIVER 3 Plus with the EB300 Extra Battery brings total capacity to 572Wh, a middle-ground number between the compact RIVER 2 and the DELTA 3 Plus models. It lists 3 AC outlets at 600W total AC output, a 1200W surge/X-Boost figure, and a 380W AC input that can reach a full charge in about an hour. Its LiFePO4 battery is rated for 3000 cycles to 80% capacity. The trade-off is outlet count: with 3 AC outlets, it offers half the AC outlets of the DELTA 3 Plus tier, so it may feel tight if you plan to run several AC-powered devices at the same time.
EcoFlow DELTA 3 Plus 1024Wh 1800W Portable Power Station LFP Battery Refurbished
The refurbished DELTA 3 Plus is the top-capacity listing among these four, with 1024Wh, 1800W total AC output across 6 outlets, and a 3600W surge figure. It also lists 1500W AC charging and a car power output of 126W max. The battery is rated for 4000 cycles to 80% capacity, which points to frequent-use scenarios. Since it is listed as certified refurbished, this listing suits someone comfortable with refurbished-condition gear. The limitation is that its output is larger than a simple phone-charging trip needs, and it is the highest-priced listing in this group.
EcoFlow DELTA 3 Plus 1024Wh 1800W Portable Power Station LFP Battery Outdoors
This second DELTA 3 Plus listing shares the same 1024Wh capacity, 1800W AC output, 6 AC outlets, and 1500W AC charging as the refurbished version. The listing name highlights outdoor use rather than refurbished condition, but the specifications match. If you are deciding between the two DELTA 3 Plus listings, the specs will not separate them; the choice comes down to which listing you prefer. The same limitation applies as with the other DELTA 3 Plus: this is a high-capacity, high-output station that may be more than you need for a night of camping with a few small devices.
EcoFlow RIVER 2 Portable Power Station 256Wh Generator LFP Certified Refurbished
The RIVER 2 is the smallest-capacity station in this comparison at 256Wh, and it is offered as a certified-refurbished unit. Its listed charging modes include AC wall outlet, 12V car adapter, and solar panel, which gives you flexibility for topping it up in different places. The battery chemistry is a good match for a backup unit you plan to cycle over time. The main limit is the 256Wh capacity: it is best for short outings and small electronics rather than extended off-grid use or powering larger outdoor tools.
Final recommendation by use case
For a compact backup that can sit in a car or tent, the RIVER 2 is the smallest and least expensive listing. For weekend use where you need more than the RIVER 2's capacity, the RIVER 3 Plus with the EB300 Extra Battery offers 572Wh and 3 AC outlets at a mid-range listed price. For high-draw devices, multiple AC tools, or home backup, the DELTA 3 Plus models deliver the largest capacity and the most AC output, whether you choose the refurbished or outdoor listing.
