A 768Wh, LiFePO4 power station light enough to carry solo, strong on single critical loads like a fridge, sump pump, or CPAP, but not built for running several high-draw devices together.

Overview
The EcoFlow River 2 Pro is a 768Wh, 800W portable power station (1600W with X-Boost) built on a LiFePO4 battery, with four AC outlets, a 70-minute AC fast charge, and optional solar input up to 220W.
This sits in EcoFlow's lineup between the compact River series and the heavier Delta units, and reviewers who own both describe it as the grab-and-go option: 17.2 lbs versus roughly 60 lbs for a Delta 2 Max. The LiFePO4 chemistry is rated for over 3,000 recharge cycles to 80 percent capacity, which EcoFlow frames as close to a decade of regular use.
- 768Wh capacity, 800W output (1600W with X-Boost)
- LiFePO4 battery rated over 3,000 cycles to 80 percent
- 70-minute AC fast recharge, up to 220W solar input
- 17.2 lbs with a built-in carry handle
Who it's for
Fits campers, musicians running small gigs, and homeowners who want backup power for a fridge, sump pump, CPAP, or laptop during an outage. Less suited to anyone expecting to run several high-draw appliances at once, since more than one demanding load reportedly drains it fast.
What buyers say
From Amazon customer reviews.
Owners are consistent on portability and single-appliance backup: several run a fridge for hours during outages, power CPAP machines overnight, or charge a laptop through the 90W USB-C line, and multiple reviewers who also own EcoFlow's larger Delta units call the River 2 Pro the easier one to carry. Complaints cluster around two things: customer support one buyer called very poor after an initial 3-day outage test, and a ceiling on how much it can do at once, with one reviewer reporting it cannot run more than a single moderate load without draining in under 30 minutes, plus slow solar and 12V car charging.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light at 17.2 lbs compared to larger EcoFlow units
- 70-minute AC fast charge
- Reviewers confirm hours of runtime on a fridge, CPAP, or sump pump
Performance notes
X-Stream fast charging pulls a full recharge from an AC outlet in about 70 minutes, and solar input up to 220W can do the same in around 3.5 hours with a compatible panel. Real-world reports back the headline numbers on single loads: reviewers clock roughly 5 hours running a fridge and multiple nights powering a CPAP with humidifier, while output drops off fast once more than one demanding device is plugged in at the same time.
