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? RIVER 2’s maximum solar input is 110W. You can use any solar panel with a rated power of 110W (or slightly above) to charge the RIVER 2 — instantly turning it into a solar generator!

You can also switch to using the DELTA Pro instead of grid power at peak energy times to save on your electric bill with clean energy. You can save significantly on your electricity bill over time when you charge with solar panels. The DELTA Pro supports 1600W solar charging input to connect four of EcoFlow’s rigid or portable 400W solar panels. The River 2 delivers the power it stores without fuss: I could use it to run and charge laptops, phones, cameras, and small appliances like a fan. My phone charged at a decent rate of 14 Watts, while my laptop got the maximum 60 Watts that the USB-C port on the front of the River 2 could output. RIVER 2 Series is a cut above the rest as the first portable power station range in the world to earn the TÜV Rheinland certification for safety.
What's in the box
RIVER 2 and RIVER 2 Max can fully charge in 60 mins. RIVER 2 Pro can fully charge in 70 mins. When charging and discharging at high wattage, RIVER 2 Max and RIVER 2 Pro may make a noise up to 62 db. Using RIVER 2 Pro Solar Generator every day decreases your whole-year carbon emissions by about 143kg. That's like planting 8 trees in a year!* I used the River 2 Max for just over three months now, and other than the minor quibble around the solitary USB-C port, I have no issues with the power station. It performed incredibly well in daily use, powering most products I have in the house without any issues whatsoever. The ability to charge the unit via solar power makes it that much more versatile, and if you choose to use the AC option, there's fast charging that takes under an hour to fully charge the battery.

The RIVER 2 is the smallest of EcoFlow’s portable power stations but still delivers 256Wh storage capacity, with an operating power output of 300W. With X-Boost, you can achieve surge power (starting watts) of 600W to run almost any small appliance and charge any personal device. It would take about four to five hours to reach total electricity storage capacity when charging using a USB-C input. The USB-C input/output is 5/9/12/15/20V, 3A, and 60W Max.The best portable power station for you depends on your use case and electricity consumption needs.

Yes, it’s a true sine wave output device rather than a simulated sine wave output device. A true sine wave system produces much “cleaner” electricity output for any connected equipment. In contrast, a simulated sine wave device has a much choppier and less stable output. Yes, it can power multiple devices simultaneously as long as the maximum wattage of the devices added together does not exceed the RIVER 2’s operating AC output of 300W.Like all EcoFlow DELTA portable power stations, you can monitor and manage your DELTA 2’s usage with the EcoFlow smartphone app from anywhere with internet access giving you freedom and flexibility. The starting power of your largest appliance isn’t the only factor in how much power you need. As mentioned above, you need to calculate the total operating electrical consumption of the sum total of appliances you want to run simultaneously. And estimate how long you want to be able to run your devices without recharging the portable power station. When you look at these models, you won’t see a definitive “best” option for all circumstances. You aren’t shopping for a portable power station for a hypothetical average person or household; you are shopping for yourself and your unique needs. Flip the device around and you’ll see a couple more connectors: one three-pin kettle connector for charging via mains AC power and a smaller, orange-coloured two-pin connector that allows you to charge the power station directly via solar panels. Expandable to achieve complete energy independence using solar power as a clean, renewable off-grid power source

On the other hand, if you just want to charge your smartphones and laptops, the DELTA Pro will seriously exceed your requirements. Starting and Running Watts of Typical Household Appliances Appliance The RIVER 2 Pro is also ideal for powering essential devices and small appliances in a van or RV. You can run 80% of high-wattage appliances, such as an RV refrigerator, along with charging all your personal electronic devices. Perhaps more impressive, however, is the speed at which it charges. From mains AC, it will charge from empty to 100% in around an hour – although via USB-C and solar it will be a lot slower.The RIVER 2 series is the first-ever collection of portable power stations to be TÜV Rheinland certified, meaning their safety, durability, and quality is evaluated by independent experts and found to be beyond reproach.
