Our take on the EcoFlow DELTA 3 Max Plus Solar Generator

The EcoFlow DELTA 3 Max Plus is a portable power station with a 3000W AC output (6000W surge) and X-Boost that runs appliances up to 3800W, including fridges, washers and circular saws. It charges from five sources, reaching 0–80% in about 43 minutes on generator charging, and takes up to 400W of solar. Capacity expands from 2kWh to 10kWh with extra batteries, and it pairs with the EcoFlow Smart Generator for automatic start and stop. It suits home backup and off-grid users who need more headroom than the 2400W DELTA 3 Max, though it is heavy and the expansion batteries add cost.
