The DELTA 3 Classic in brief

One fact sets the DELTA 3 Classic apart from its DELTA 3 siblings: it cannot be expanded. In return it weighs 26.6 lb, a pound under the DELTA 3, and it still delivers 1,800 W of AC, the third-highest in the 25-station class of 700 to 1,500 Wh. Inside are 1,024 Wh of LFP rated for 4,000 cycles to 80 percent, and the surge rating is 3,600 W. It fills from the wall in 0.7 hours at 1,400 W. Solar enters through an XT60i port up to 500 W, using EcoFlow's Solar to XT60i charging cable. The UPS switchover is 10 ms, and the warranty runs 5 years. EcoFlow lists an operating range of 14 F to 113 F.

How long the DELTA 3 Classic runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. About 870 Wh is usable, so a 1500 W microwave runs 35 min to 52 min and a 45 W Wi-Fi router lasts 19 h to 4 days.

Work out your own mix of loads. A red bar means it draws more than the 1,800 W this station can supply.

Solar panels for the DELTA 3 Classic

Its XT60i port takes 11 to 60 V, up to 15 A and 500 W. A panel's voltage rises in the cold, so the marks below show each one at 14 F, and a pass here keeps 10% of headroom under the maximum.

Who the DELTA 3 Classic suits

Pick it for a fixed-size backup: a fridge, a sump pump at 1050 W for 50 min to 1.1 h and a few small things, with no plan to add batteries later. If you might add capacity, the DELTA 3 has the same 1,024 Wh and goes to 5,120 Wh. The Jackery HomePower 1000 v2 is lighter at 23.4 lb but delivers 1,500 W of AC, 300 W less than this model.
