- EcoFlow River 3 Plus: Doubles that with 600 watts of continuous power and a surge capacity of 1,200 watts.
Both units support EcoFlow’s X-Boost technology, which allows you to run devices that require more wattage than the rated output, up to certain limits. However, use caution with X-Boost as it can potentially damage sensitive electronics if not compatible.
Both power stations deliver pure sine wave output, which means clean and stable power for sensitive devices like fans, TVs, projectors, and computers. Unlike modified sine wave power stations, these won’t cause humming noises or screen distortion.
3. XGen Power Technology
EcoFlow has incorporated Gan power technology into these models, a newer innovation that improves efficiency. This technology allows you to run devices or appliances under 100 watts for twice as long compared to traditional setups—great news for powering small electronics efficiently.
4. Uninterruptible Power Supply (UPS) Capability
If you want to use these power stations as a UPS for your computer or other devices, both support this feature, but with some differences:
- The River 3 has a UPS switching speed of 20 milliseconds.
- The River 3 Plus improves this to just 10 milliseconds, offering faster switching and better protection for connected devices.
The USB Type-B port on the River 3 Plus is specifically designed to connect to a computer and facilitate this rapid switching, making it a compelling choice if UPS functionality is important to you.
5. Battery Capacity and Expansion Options
Battery life is crucial when choosing a portable power station, and here the River 3 Plus offers a significant advantage.
- River 3: Comes with a 245-watt-hour (Wh) lithium iron phosphate (LiFePO4) battery.
- River 3 Plus: Offers a slightly larger 286 Wh LiFePO4 battery with built-in expansion capabilities.
The River 3 does not support external battery expansion, so what you get is what you have. The River 3 Plus, on the other hand, supports two expansion batteries:
- EB300 Expansion Battery: Adds 286 Wh.
- EB600 Expansion Battery: Adds a substantial 572 Wh.
With the EB600 attached, the River 3 Plus can reach a total capacity of 858 Wh, almost quadrupling the runtime compared to the base River 3. This modular approach is fantastic for longer trips or extended power outages.
6. Unique Features of the EB600 Battery
The EB600 expansion battery is more than just extra capacity. It includes a USB-C port rated at 140 watts that works both as an input and output. This means you can use the EB600 as a standalone power bank to charge devices or recharge the battery itself using compatible USB-C solar panels or chargers. This versatility adds another layer of convenience to the River 3 Plus setup.
7. Charging Inputs: Solar, AC, and Car
Charging flexibility is another area where these two differ:
- Solar
- River 3: Supports 110W input with 11- 30V range.
- River 3 Plus: Up to 220W with 11- 55V, accommodating more solar panels.
- AC Charging
