Big-ass battery maker EcoFlow is announcing the redesigned River 2 series today fitted with long lasting LFP (LiFePO4) batteries and lots of ports to power your AC and DC devices. These are batteries sized to power your weekend away or a music festival.

The River 2 series consists of three batteries that vary by storage capacities, maximum AC power (pure sine wave) output, and charging ports:

  • River 2: 256Wh, 300W AC output, and 5 output ports
  • River 2 Max: 512Wh, 500W, and 9 output ports
  • River 2 Pro: 768Wh, 800W, and 10 output ports

The batteries can be charged in four different ways: a standard AC wall outlet, portable solar panels, a 12V car socket, and USB-C. The base River 2 can charge to 100 percent in as fast as 60 minutes, while the Max and Pro models take a bit longer due to their larger batteries.

The River 2 series, like most EcoFlow batteries, can be stacked and connected to take advantage of the company’s X-Boost tech. X-Boost is a little trick that lowers the output voltage to allow some devices rated up to 1600W (like heat guns and espresso machines) to operate off the River 2’s inverter. It doesn’t work with all high-wattage devices, though.

Vanlifers concerned with maximizing space will appreciate the handle placement which has been moved to the side. The resulting flat surface on top can be used as a makeshift table. The batteries can also serve as dual-use kettle bells with the entry-level model weighing 7.8lbs (3.5kg), the Max 13.4lbs (6.8kg), and Pro 17.2lbs (7.8kg). I’m serious. Staying Instagram pretty is hard work — vanlife’s not all fairy lights and sunsets, you know.

Other features include an iOS and Android app that lets you monitor your battery inputs and outputs over Bluetooth or Wi-Fi. Something I found to be supremely useful when I reviewed an EcoFlow Delta Pro with the company’s folding 400W solar panel this summer. The River 2 can also serve as a UPS at home when you’re not traveling about.

The base River 2 model is priced at $239 / €299 / £269, the River 2 Max at $469 / €599 / £549, and the big boy River 2 Pro lists for $599 / €799 / £749. They’re available to buy starting November 9th in both US and European configurations.
