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. 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. If you need something compact to power more devices, RIVER 2 Max offers a 512Wh capacity and weighs just 13.2 lbs (6.1 kg). Maybe not ideal for long hikes, but certainly manageable. Battery/Storage Capacity RIVER 2 Max also uses advanced LFP battery chemistry. EcoFlow’s LiFePO4 batteries have an extraordinarily long lifespan: six years longer than the industry standard.
EcoFlow RIVER 2 series portable power stations start at 7.7 lbs (3.5 kg) and go up to 17.2 lbs (7.8 kg). The EcoFlow RIVER 2 series utilizes cutting-edge Lithium Iron Phosphate battery chemistry — also known as LFP or LiFeP04. LiFePO4 is a newer subset of the traditional Lithium-Ion (Li-Ion) battery chemistry commonly found in older PPS models and Electric Vehicles. If you’re camping without access to shore power or hookups — or simply want a cleaner way to generate electricity, RIVER 2 Max connects with up to two 110W solar panels or a 220W Bifacial Portable Solar Panel to give you renewable, green power.If any of your devices have a higher starting wattage, you’ll also need to factor that in. RIVER 2 provides up to 600W starting watts (surge power) using X-Boost mode. Can You Run RIVER 2 and Charge It at the Same Time? RIVER 2 is the smallest portable power station in the RIVER 2 series. It’s more powerful than a power bank and more compact than other portable power stations.
With 300W operating AC output (600W starting wattage with X-Boost), you can run up to 99% of consumer electronics. But a maximum operating AC output of 300W severely limits the kind of appliances you can run with RIVER 2. Essentially, anything with an operating wattage above 300W — or a starting wattage requirement of 600W+ — simply won’t work. Unlike two DELTA Pros (for example), you can’t connect two RIVER 2s together to use them in parallel. 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). You can recharge while you operate using any of RIVER 2’s four charging methods — including solar panels. Can I Connect Two RIVER 2s Together in Parallel?For example, if you want to power a 50W laptop and a 200W 20” (50.8 cm) box fan, you’d get a total wattage of 250W. Divide the 256Wh capacity by 250W of power needed, and you could run these appliances for roughly one hour. If you need a compact option that can power 80% of home appliances but still weighs under 20 pounds, at 17.2 lbs (8 kg), RIVER 2 Pro offers 768 Wh battery storage — perfect for off-grid weekends away with the family. AC Output
Like the rest of the RIVER 2 series, RIVER 2 Pro features advanced LFP (LiFePO4) battery technology that leaves traditional Li-Ion and lead acid batteries in the dust. EcoFlow RIVER 2 Pro: The Final Verdict However, EcoFlow portable power stations don’t support 0ms switching. For most electronics, a 30-ms interruption in power is negligible. You may not even notice it. However, there IS an interruption — unlike with a UPS. The 220W PV panel comes at a higher price, and some of the energy it captures will likely go to waste… All of these ports make RIVER 2 the most versatile 7.7 lb (3.5 kg) PPS on the market. But every port is also an opportunity for water to make ingress into your PPS. While your RIVER 2 will surely survive a slight sprinkle, don’t leave it outside in the rain — and don’t immerse it in the water! 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.
The River 2 Max charges just about anything you have, and has all the ports you need.
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 EcoFlow RIVER 2 Max features four pure sine wave AC outlets that deliver up to 500W (1000W of surge power with X-Boost.)
However, just because the RIVER 2 is among the most durable portable power stations on the market doesn’t mean you should drop it in the ocean. For one thing, RIVER 2 has multiple AC, DC, USB-A, and USB-C ports so that you can charge all your devices at once. However, you can use two RIVER 2s simultaneously but separately. For example, use one to power your lighting while the other powers your box fan.EcoFlow RIVER 2 series portable power stations offer the best compact power solution for off-grid adventures. 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 Here are the essential factors to consider when purchasing an EcoFlow off-grid power solution that’s right for you. Portability AC outlets deliver up to 800W, ideal for powering more demanding devices. RIVER 2 Pro can run up to 80% of high-wattage home appliances.
