Significantly, LiFePO4 batteries require no cobalt — one of the primary materials used in traditional Li-ion batteries. 70% of the world’s cobalt comes from the Democratic Republic of Congo, where both mining and processing are carried out under extremely cruel labour conditions by children as young as six years old. Can You Keep RIVER 2 Outdoors? You don’t want to wait half a day to charge up when you’re on the go. All EcoFlow portable power stations feature X-Stream — offering lightning-fast charging and intelligent battery management.
You’ll often hear portable power stations called solar, battery, or even portable generators. Ultimately, they’re all battery-powered devices.
For example, you can connect it to an EcoFlow 220W Bifacial Portable Solar Panel since the solar Input of RIVER 2 is 8A Max,11-30V 110W, and the Open Circuit Voltage of EcoFlow 220W Bifacial Portable Solar Panel is 21.8V, which falls within that range. However, any extra electricity produced over 110W gives you no additional benefit. To be safe, allot five to six hours for your RIVER 2 to charge fully using the USB-C input. Is RIVER 2 Expandable? That’s enough starting and running wattage to turn on and operate up to 80% of essential appliances. Fast Charging: 0-100% in 1 hour
The EcoFlow RIVER 2 series offers industry-leading portable power stations and whole home generator solutions for any application. The RIVER 2’s maximum solar input is 110W. While using a solar panel with higher-rated power might not damage the PPS, you won’t generate any additional electricity — you’ll end up wasting any solar energy captured that exceeds the 110W solar input cutoff point.RIVER 2 uses LiFePO4 batteries, a newer subset of lithium-ion batteries. Compared to other lithium-ion batteries, batteries with LiFePO4 (lithium iron phosphate) chemistry require no maintenance, are safer, and have a longer lifespan. Like EcoFlow’s DELTA series, the RIVER 2 series comes in various shapes and sizes, with different features tailored toward different users and scenarios. The amount of time that the RIVER 2 PPS can power your appliances between charges depends entirely on your appliances’ starting and running wattages and how many devices you run simultaneously. Even if your appliance has an operating wattage of 300W, RIVER 2 could only run that one appliance. And, due to the battery storage capacity of 256Wh, RIVER 2 can’t even run your 300W device for an hour (watt-hours and kilowatt-hours measure electricity consumed over time).
Or, you can go solar. Depending on environmental conditions, such as available sunlight, RIVER 2 Pro can recharge 0-100% in 4.5-9 hours using a 22oW Bifacial Portable Solar Panel.Here’s an in-depth look at what each RIVER 2 model has to offer, depending on your specific use case. The RIVER 2 takes about three hours to charge fully using your car’s cigarette lighter. Its maximum DC input is 12/24, 8A, or 100W Max, and the PPS battery storage capacity is 256Wh.
My intension with the review was to fully charge the battery on the River 2 Max and drain it several times. So I started out using it for charging phones and a multitude of accessories around the house, and I immediately realized that wasn’t going to cut it. The River 2 Max has a 512Wh battery, and it would easily charge the likes of the Galaxy S23 Ultra for a few weeks before the battery ran out. Once connected, the WiFi indicator will pop up on the screen as well and the app is fairly straightforward in allowing status indicators at a glance, in addition to controlling the various outputs and inputs. Not pictured in the GIF above is a time chart for charging and discharging power levels, which shows how long the various charging inputs have been on for and how efficiently at that—quite handy for solar charging should you need to see whether to move portable solar panels around to better face the sun. The connection is over WiFi, so you can theoretically monitor the power station from a good distance away, which is handily paired with pre-set alarms that will pop up as notifications. The settings menu has plenty of other options, some of which are shown here. In particular, I appreciated the ability to set the maximum charge level, which can be useful even on this LiFePO4-based battery unit that is good for 80%+ capacity after 3000 cycles compared to the Li-ion RIVER Pro, which only had this 80% rating for the first 800 cycles. As such, you can be rest assured about using the RIVER 2 daily for years at a time, and this is also why EcoFlow has increased the warranty period to five years on the RIVER 2 lineup from the two years previously offered. You can also select the maximum charging levels in each mode, limit the output as deemed necessary, and have firmware updates done to the unit that can add more features or resolve any bugs typically seen early in the product life cycle. This app removes the need for an onboard menu with touch screen or navigation buttons, keeping the unit physically smaller and providing more customization, control, and monitoring—a very useful selling point in itself. LiFePO4 offers many advantages over Li-Ion, including longer lifespans, faster recharge times, and increased performance in extreme temperatures.Since 60W is the maximum USB-C input, and the actual charge may be lower, you can round up to account for the potential extra time to charge fully. If the ambient temperature increases beyond this range during storage, the battery discharge rate will also increase. Is RIVER 2 a True Sine Wave Output Device? You can trust RIVER 2 with even your most sensitive electronic devices (like laptops and external hard drives). How Long Does RIVER 2 Take to Fully Charge Using the DC Car (Cigarette Lighter) Input? Additionally, you can expand a PPS like the DELTA Pro to provide up to 25kWh of electricity storage — enough to run many households for a full day. Using RIVER 2 Max six times a week, 3000 full 100% cycles will last 9.6 years until it drops to 80%.
