EcoFlow RIVER 2 Pro vs. EcoFlow DELTA 2
A 768Wh camping and CPAP unit vs. a 1,024Wh unit that can handle kitchen appliances.
If you only need to power a CPAP, Starlink, Wi-Fi router or 12V car cooler, the 17.2 lb RIVER 2 Pro is enough. If you want to back up a full-size refrigerator, coffee maker or microwave, the DELTA 2's 1,800W inverter is the safer choice.
