The DELTA 3 in brief

Wall charging is quick: 0.93 hours at 1,500 W, second-fastest among the 24 stations in the 700 to 1,500 Wh class. The DELTA 3 holds 1,024 Wh of LFP in a 27.6 lb case and sends out 1,800 W, with a 3,600 W surge rating. It follows the DELTA 2, which EcoFlow no longer sells new. The changes are a 10 ms switchover, an XT60i solar port with a 500 W limit, and 4,000 cycles to 80 percent. A DELTA 3 Smart Extra Battery adds 1,024 Wh each, up to 4 of them, for a ceiling of 5,120 Wh. The operating range is 14 F to 113 F, and USB-C output reaches 100 W.

How long the DELTA 3 runs things

Times use about 85% of the rated capacity, the part left after inverter and battery losses. Of the 870 Wh usable, a 192 W chest freezer draws 22 h to 38 h, while a 1500 W kettle gets 35 min.

Refrigerator9.5 h to 25 h
Gas furnace blower1 h to 2.9 h
Starlink8.7 h to 12 h
Sump pump50 min to 1.1 h
TV8.5 h to 12 h
E-bike charger5.2 h to 9.1 h
Laptop9.1 h to 25 h
Window air conditioner1.2 h to 1.9 h
Microwave35 min to 52 min
Space heater33 min to 40 min
Electric blanket4 h to 7.9 h
Coffee maker35 min to 1.5 h

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

Solar time assumes panels reach 75% of their rating. Figure it for your state and panels.

Solar panels for the DELTA 3

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.

Extra batteries for the DELTA 3

Who the DELTA 3 suits

A good match for a home backup that starts small: fridge, router and sump pump now, extra batteries later. If you mostly use solar, the DELTA 3 Plus takes 1,000 W instead of 500 W and has a 140 W USB-C port, at the same weight. The DELTA 3 Classic drops to 26.6 lb and cannot be expanded. For a lighter pack with a long life, the Jackery HomePower 1000 v2 is 23.4 lb and rated 6,000 cycles to 70 percent, but gives 1,500 W.

FAQ

How fast does the DELTA 3 charge from a wall outlet?

In 0.93 hours at 1,500 W. A car's 12 V socket takes 10.7 hours, and solar at the full 500 W takes 2.7 hours.

How many extra batteries can the DELTA 3 use?

Up to 4 DELTA 3 Smart Extra Batteries of 1,024 Wh each, for a system maximum of 5,120 Wh.

Can the DELTA 3 run a hair dryer?

A 1875 W hair dryer is just over the 1,800 W output, so it sits outside what the station is rated to run.

What solar panels stay inside the DELTA 3's limits?

The input window is 11 V to 60 V at up to 15 A. Single 400W panels, or pairs of 160W and 220W portable panels, are inside it, each using an MC4 to XT60i cable.
