EcoFlow DELTA 2

9.3/10Best Choice

The EcoFlow DELTA 2 is a 1,024 Wh LiFePO4 power station with 1,800 W of AC output and fast wall charging. It suits home backup for essentials and RV or camp trips where a 27-pound unit is fine to carry.

Why it's here

  • 1,024 Wh LiFePO4 with 1,800 W output and a 2,700 W surge rating
  • About 80 minutes to a full wall charge, among the fastest here
  • Expandable with extra batteries and works with EcoFlow solar panels and the app
  • Many ports, including AC outlets, fast USB-C and a 12V car outlet

Keep in mind

  • Around 27 pounds, so it is a two-handed carry
  • Older design, so newer models charge faster or weigh less
  • Fan noise rises when it runs near full load or charges at full speed

Why No. 1 beats No. 2

The EcoFlow DELTA 2 (9.3) beats the Anker SOLIX C1000 Gen 2 Portable Power Station (A1763) (9.2) because it leaves owners a little happier. No. 2 is the newer design, but not by enough to close the gap.

About the EcoFlow DELTA 2

The DELTA 2 stores 1,024 Wh in a LiFePO4 (LFP) battery, which EcoFlow's DELTA line moved to from the older NCM chemistry. AC output is 1,800 W continuous with a 2,700 W surge, and X-Boost can run some heavier appliances up to about 2,200 W by limiting the voltage. The unit weighs about 27 pounds and measures roughly 15.7 x 8.3 x 11 inches.

Charging is the main strength. A wall outlet fills it in about 80 minutes, and a reviewer at SlashGear measured more than 1,100 W going in. Solar input tops out at 500 W, and EcoFlow's own panels connect directly. A 500 W array brings it to full in roughly 3 hours in good sun. It can also charge from a car and from EcoFlow's Smart Generator on longer outages.

On the output side there are AC outlets, two 100 W USB-C ports, USB-A ports, two DC5521 barrel ports and a 126 W 12V car outlet. The EcoFlow app works over Bluetooth or Wi-Fi: it shows charge level, switches ports on and off, and sets charging speed. It can also silence the beep. Extra Smart Extra Batteries plug into the DELTA 2 and cannot run on their own. One roughly doubles the capacity, and the unit can pass power through to act as a backup supply when the grid drops.

What owners report about the EcoFlow DELTA 2

We found little owner feedback specific to the DELTA 2 on pages we could open, so this section is short.

The one owner thread we read, on the Bambu Lab forum, was critical about one use: after about six months the owner found the unit unreliable as a UPS for 3D printers, as some printers stopped during brownouts. That is one household, not a pattern, but it fits the unit's own spec: it switches to battery in a fraction of a second, not instantly. The same owner said EcoFlow arranged a replacement and pickup without trouble. Broader owner patterns on fan noise, app support and long-term capacity were not something we could confirm for this model from sources we opened.

Who the EcoFlow DELTA 2 suits

The DELTA 2 fits people who want about 1 kWh of backup for a refrigerator, router, lights and phones, or a power source for an RV, van or campsite. The fast wall charge helps when power returns only briefly, and the app, solar input and extra batteries let it grow. It is a good match for a household that expects to add capacity later.

Look elsewhere if weight matters or you want the newest charging speeds. The Jackery Explorer 1000 V2 is a lighter 1 kWh option, and the Anker SOLIX C1000 Gen 2 has a bigger inverter and quicker charging. For running a whole outage with larger appliances, the EcoFlow DELTA 2 Max or the BLUETTI Elite 200 V2 hold twice the energy. The EcoFlow RIVER 3 is the smaller, quieter pick for phones and laptops.

Questions about the EcoFlow DELTA 2

Is the EcoFlow DELTA 2 worth it?

Yes, for 1 kWh of backup or RV power with fast charging, solar support and room to add batteries. It is heavier and older than newer models, so a lighter or faster-charging station may suit you better if you carry it often.

How long will an EcoFlow DELTA 2 run a refrigerator?

About 7 to 14 hours for a full-size refrigerator, according to PopSci's review. A 60 W mini fridge could run around 15 hours, per Backup Power Hub's calculation. Your fridge's actual draw, the room temperature and how often the door opens change this.

Is the EcoFlow DELTA 2 discontinued?

It may be. EcoFlow's US page for the DELTA 2 now shows the DELTA 3, and one US guide describes the DELTA 2 as discontinued there, but another still lists it as a current buy. Check that the listing is in stock and sold by a seller you trust before buying.

What's the difference between the EcoFlow DELTA 2 and DELTA 3?

Both hold 1,024 Wh of LFP and put out 1,800 W. The DELTA 3 charges faster (about 56 minutes against about 80), has a higher 3,600 W surge rating and a longer rated cycle life, and expands to 5 kWh. The DELTA 2 has more USB-A ports.

How we score it

Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
