EcoFlow River Portable Power Station – Review

Portable power stations have been growing exponentially in popularity, and for good reason. They provide added utility beyond what a smaller external battery pack offers, as they typically include AC and DC power outlets and power-hungry devices. Depending on the combination of the total power station capacity you choose and the devices that you need to power, you could potentially be set for a couple of days off-grid.

Why They’re So Popular

Traditionally, off-grid power meant that you had to use a gas-powered generator, which is both heavy (at its lightest around 50lbs) and noisy – especially when used at a quiet campsite. Other requirements include the actual gas, light maintenance, such as routine oil changes, and maintaining a proper safety distance from the exhaust. With battery power stations, all you have to do is charge them up via a wall socket, solar power, or in your car while driving, and you’re good to go.

One drawback of a battery power station is that they generally cannot power the more demanding appliances that their gas counterparts can; however, that’s a non-factor for the vast majority of the target market. For many of us, we need multi-day power for mobile devices such as phones, laptops, and cameras – and a battery power station is perfect for that use case. Another benefit is in the weight and space savings, typically weighing a fraction of gas generators and about the size of a lunchbox. Plus, as mentioned earlier, no gas or oil to deal with!

What Is The EcoFlow River

The EcoFlow River started as a Kickstarter project. It claimed to have a unique feature called X-Boost, which diverts the power from all 3 of its AC outlets (up to 600watts each) to a single one, providing up to 1800watts for certain more demanding appliances such as a hot plate or a coffee maker (for when the caffeine withdrawal starts hitting hard).

Main Features

Aside from the EcoFlow River’s hat trick, another great feature is its modularity. The main unit has a capacity of 288Wh, and an available expansion battery that seamlessly attaches to the bottom with 4 screws, doubling the total capacity to 576Wh while adding only 5.5lbs. This means that on shorter day trips where you only need light energy, you can save some weight in your kit and bring only the main unit (around 11lbs). Overall package size is around (in inches) 11.3 X 7.3 X 7.7 – with the expansion battery increasing the height dimension by 2.3 inches.

The expansion battery also adds a strip of LED lighting to your power station, if you’re into that sort of thing.

All of EcoFlow’s power stations have quick charge via the provided AC cable. In the River model, the main unit can be fully charged from empty in about 1.5 hours. With the expansion battery, roughly double that. Other charging options include solar (up to two 110W panels) and DC charging while you’re driving to your destination.

Easy-to-read Display

One of the best features, in my opinion, is the informative display – it will show you the current power input/draw, total use time left based on the said draw, and current remaining battery life. It’s a color-on-black LCD, which makes it easy to read even in daylight.

Additional Ports

Other charging ports on the River include a PD USB-C (100 watts) for compatible laptops, 2 regular-speed USB-A, and one fast-charge USB-A.

Emergency Light

There is a built-in light with a low/high mode and an SOS mode. This can be useful when you need to plug in devices or to catch someone’s attention if your rig breaks down in the dark.

How does it work on the app?

Finally, the EcoFlow app lets you monitor the device’s power levels and manage its settings via Bluetooth. The app is also needed to enable/disable X-Boost high wattage mode, which, unfortunately, is the only way to do so.

How To Use

Using this power station is pretty straightforward – turn it on and plug in your device of choice. All USB ports are always on, whereas the DC and AC ports have dedicated buttons to enable them. This is likely to save power, as using the AC ports turns on an internal fan to keep the circuitry cool.

Real-Life Scenario

My family and I recently experienced a power outage that lasted around 18 hours, and this device proved its worth in gold. I decided to plug in the modem and router to keep the internet running in our house because we have poor cell signal. With an average power draw of around 10-12watts, the display showed a total run time of about 28 hours. This meant I had plenty of juice to keep our phones charged and the white noise machine running for our baby. Keep in mind, however, these numbers are only for the main unit.

With the addition of the expandable battery mentioned earlier, you can expect double the usage. For shorter outages of a few hours, we also use this device to keep the refrigerator and deep freezer running at the correct temperature.

Overall Impressions

I purchased the EcoFlow River last year with my own money, so this review is unbiased. I couldn’t be happier with my purchase as I’ve gotten some crucial use out of it. I am aware of the competitors in this space, but I couldn’t ignore the value proposition EcoFlow presented (plus I’m a techie, so they win there). This is a solidly built unit, and I like the ability to remove the expansion battery when I don’t need a ton of power and weight savings are the priority.
