EcoFlow Delta 2 Max Solar Generator

Ditch the Gas-Powered Generator for the EcoFlow Delta 2 Max Solar Power Station

Gas-powered generators have had their run, and in fact, some people still consider them the kings of off-grid power. EcoFlow aims to change some minds and turn some heads with the Delta 2 Max portable power station. How does this model stand out in the growing solar- and AC-powered generator market? We’re taking a look at it so you know what to expect.
