The base $4,299 E10 system starts with one Power Module and one battery that can keep a few individual appliances running, and scale up to power an entire home. The 110.2-pound inverter is good for a steady 7.68kW output (or 10kW for 90 minutes). It can produce up to 28.8kW (120 LRA) peak when fitted with a single 6kWh battery, or 37.2kW (155 LRA) when configured with two or more batteries - enough to start a 5-ton air conditioner.
EcoFlow makes some of our favorite portable options, and Amazon is making it easy to grab one without shelling out thousands of dollars. Right now, you can grab the EcoFlow Delta 2 power station for just $349, after a massive 50% off its retail price. It's one of the lowest drops we've seen in a while, but it won't last long. If you've been holding off on buying backup power, this is a good time to make the move.
