  • I like it
Style: DELTA 3 Max+500W AC
This unit came quickly and has really nice packaging. Charges quickly and seems to output plenty of power. Time will tell if it holds up but it sure seems like a very nice unit.

  • Not 1000 watts solar max. Only 500!
Style: DELTA 3 Max+500W AC
Solar input is only 500 not "The EF ECOFLOW DELTA 3 MAX has a maximum solar input of 1,000W. This allows you to connect multiple solar panels in parallel to achieve faster charging speeds, as long as the total combined output doesn't exceed 1,000 watts"
