The EcoFlow River Mini Wireless Portable Power Station – CleanTechnica Review

The sharp reduction in the price of lithium-ion batteries over the last decade has been crucial in making emission-free electric vehicles more affordable and has also opened the door to a whole new generation of portable power plants.

EcoFlow has been designing and building portable power plants since 2016 and sent us their smallest portable device, the EcoFlow River Mini Wireless, to drive it through the pace. At 9.8 “x 5.5” x 5.2 “and just over 6 pounds, the River is a compact device that is hardly larger than a small stack of paperback books. In the compact package, the River stores 210 watt-hours of capacity and packs the ability to push that power out of a pair of 300-watt AC outlets each with voltages of up to 600 watts.

In practical applications, River is unique in that its high power capacity coupled with a useful amount of storage capacity makes it the best option on the market for a wide range of applications. This is especially true in cases where electricity is used for heating. For example, the EcoFlow River can power a small hot water boiler or even a small coffee pot. It was plenty of power to use my 300 watt single serving hot water tank mug even though you would not be able to run it more than once or twice per day. charging.

More mundane tasks like recharging phones, laptops, tablets, phones and the like are trivial for the EcoFlow River Mini Wireless. These typically draw less than 100 watts and most live in the very low end of this range. My travel tablet draws about 15 watts in fast charging mode and my smartphone drinks about 5 watts, for example.

As the name suggests, River Mini Wireless also has an integrated “rooftop” wireless Qi charger for smartphones. The charger is cut at the top to make it easier to set up your phone without it slipping off. It’s a handy feature that not only adds wireless capabilities to the device, it also means less cable to carry. It’s huge for a portable power system.

The EcoFlow River Mini Wireless delivers powerful power for such a small device, with the ability to charge not only from a standard electrical outlet, but also from a single 100 watt solar panel at 11–39V, 8 amps. With a 100 watt solar panel, the EcoFlow River Mini Wireless had to be fully recharged in 3-6 hours. It has a covered panel for charging, which makes it easy to connect a cable to the wall, which surprisingly does not require a charging block. It’s a straight cable that just connects.

The ability to charge from solar panels makes it an option for extended off-grid situations. Camping for a week? Bring a fully charged EcoFlow River Mini Wireless and a solar panel and you’re good to go. It is worth testing all your devices before any trip like this to ensure that the solar panel charge works as expected and produces enough power for all your devices. EcoFlow’s support even said it would be nice to use one of their 160 watt solar panels with the system for a full charge in 1-2 hours.

It is also worth confirming that the river is charging your devices. I would not expect any problem with low power consumption and USB devices, but for more specialized or higher power devices, they may have some funky behavior that could prevent them from drawing power. Appliances such as refrigerators, compressors, etc. often use non-standard power start curves. Better to be on the safe side.

For people looking for more storage capacity, EcoFlow has a range of larger packages in the River and Delta product families with lots of great features. For more information on the EcoFlow River or to buy one for yourself, head over to its official website.
