I love power stations. They're the off-grid adventurer's answer to the power bank. They're a huge box of batteries that can charge USB devices and run gadgets that need AC power.

But power stations can be big, weighty things. That's fine if you have a vehicle to haul your gear to your destination, but if you're going on foot, most power stations are just too heavy to lug about.

And most of those that are small enough to carry are too small to be useful.

The EcoFlow River 2 Max sits in the middle -- compact enough to be portable, big enough to be practical.
