The EcoFlow River 2 packs a 256Wh battery and 300W output into a 7.7 lb unit that's easy to toss in a Subaru's cargo area without it taking up real space. It runs camp lighting, charges phones and cameras, and covers most small-appliance needs for a night or two away from power. A full charge from empty takes about 60 minutes, whether you're topping up from a wall outlet at home or a compatible source at camp. Canada-wide shipping from Flat 4 Offroad in Calgary.
