What can it power?
Almost anything that plugs into a standard 120V outlet and draws under 1,800W: refrigerators, TVs, laptops, routers, coffee makers and power tools. X-Boost lets it run many higher-wattage appliances, up to 2,600W, at reduced power.
How fast does it recharge?
From a wall outlet, about 45 minutes to 80% and about an hour to full. It also takes up to 500W of solar, and charges from a car or a generator.
Can it work as a UPS?
Yes. Keep it plugged into the wall and plug your devices into it. If the power cuts out, it switches to battery in 10 milliseconds, fast enough to keep computers, routers and NAS drives running.

Estimates assume about 85% of the 1024Wh is usable after conversion losses. Real runtime depends on the device, its settings and the temperature.
Battery
Built to last about a decade.
Inside are automotive-grade, full-tab LiFePO4 (LFP) cells, a chemistry known for thermal stability and long cycle life, watched around the clock by a smart battery management system.
-
Full-tab LFP cellsLower internal resistance means less heat and more efficient power flow.
-
24/7 battery managementConstantly watches voltage, current and temperature to protect the cells.
-
EV-grade cell-to-chassis buildStands up to overnight condensation and bumps on rough roads.
The roughly 10-year lifespan is EcoFlow's estimate from internal simulation testing with proper use. Actual results may vary.
Quiet
Quiet enough to sleep next to.
Below 600W it runs at 30dB or less, about as quiet as a library. Keep it in the bedroom during an outage, or by the tent at night.

Why not just a gas generator?
Generators are great for long, heavy loads. For everyday outages, home offices and camping, a battery is simpler.

Is DELTA 3 Classic right for you?
Made for you if…
- You want backup for the essentialsFridge, Wi-Fi, lights, phones and a laptop through a typical outage.
- You work from homeThe 10ms switchover keeps your desk online when the power blinks.
- You camp, van or tailgateQuiet, fume-free power you can carry and recharge with solar.
- You want it ready without thinking about itLFP cells hold up for years, and Storm Guard tops it up before bad weather.
Not the right pick if…
- You want to back up the whole houseCentral air, electric heat and well pumps need a much larger system.
- You need 240VOutput is 120V only, so dryers and other 240V appliances won't run.
- Your appliance needs more than 2,600WThat's the X-Boost ceiling. 1,800W is the continuous limit.
- You need to fly with itAt 1024Wh it's well over airline battery limits.

FAQ
Questions, answered.
How long does it take to charge?
From a standard wall outlet, about 45 minutes to 80% and about an hour to full. Solar charging depends on your panels and the weather; it accepts up to 500W of solar input.
Will it run my refrigerator?
Yes. A full-size fridge drawing around 120W would run for roughly 7 hours on a full charge. Fridges cycle on and off, so real-world runtime varies.
Can I use it while it's charging?
Yes. That's how UPS mode works: plug it into the wall, plug your devices into it, and it powers them while keeping its own battery full.
Is it safe to use indoors?
Yes. There's no engine, fuel or exhaust. LFP chemistry is thermally stable, and the battery management system watches the cells around the clock. Give it some airflow and keep it dry.
How loud is it?
30dB or less with loads under 600W, about as quiet as a library. Under heavy loads or while fast charging, the cooling fans spin up and you'll hear them.
What can I charge it with?
A wall outlet (fastest), solar panels up to 500W, your car while driving, or a generator. EcoFlow solar panels, Alternator Chargers and Smart Generators are sold separately; see the compatibility chart in the specs.
What ports does it have?
120V AC outlets (1,800W total), two USB-C ports (100W and 30W) and one USB-A port (18W).
Do I need the app?
No. It works out of the box. The EcoFlow app (Wi-Fi or Bluetooth) adds live monitoring, scheduled charging and Storm Guard.
How long will the battery last?
The LFP cells are built for a long service life; EcoFlow estimates about 10 years with proper use. For long-term storage, keep it somewhere cool and dry and charge it every few months.
Can I take it on a plane?
No. At 1024Wh it's far above airline limits for lithium batteries, in carry-on or checked bags.
What's the difference between the bundles?
Same power station, one or two units. Two give you 2,048Wh in total: one for the house and one for the car or cabin, or use them back to back for longer outages.
Be ready before the lights go out.
1024Wh of quiet, fume-free backup that recharges in under an hour.
