Connect appliances to the station
Choose what has to keep running during a blackout — we will work out how long the station lasts and whether it can carry the load. Choose appliances — we will work out how long the station lasts.
An estimate: 85% of the station capacity (inverter efficiency) divided by the total power of the appliances; charge is shown after a 4-hour blackout. Real figures depend on how the appliances are used.
The EcoFlow DELTA 3 1000 Air is a new compact EcoFlow station with 960 Wh, a 500 W output and switchover to battery in 10 ms. It has an upright body that fits next to a desk or router, runs quietly at up to 39 dB and charges from the mains to 80% in about two hours. If you want to buy EcoFlow DELTA 3 1000 Air as an uninterrupted power source for a home office, below are the specifications, run times and a comparison with other stations.
What the DELTA 3 Air line is
DELTA 3 Air is a new EcoFlow line that the official distributor introduced in Ukraine in 2026. It has two models: the DELTA 3 1000 Air and the EcoFlow DELTA 3 2000 Air. Both have an LFP battery, a UPS mode with 10 ms switchover, a built-in stabiliser that lets them charge at grid voltages from 100 to 240 V, and control through the EcoFlow app.
The body is tall and narrow, with built-in handles. According to EcoFlow, the CTC (Cell-to-Chassis) design makes the station more resistant to vibration and knocks.
Who this station is for
The DELTA 3 1000 Air is designed as the base of a home office during outages. According to EcoFlow Ukraine, it powers:
- a Wi-Fi router for up to 43 hours;
- a laptop for up to 15 hours;
- lighting for up to 42 hours.
The exact time depends on the consumption of your devices. A 500 W output suits a router, laptop, monitor, TV and gas boiler. For a fridge, microwave or kettle the power is too low: you need a station from 1000 W, such as the DELTA 3 2000 Air or the DELTA 3.

UPS mode
You can keep the station plugged in permanently and power a router, computer or boiler through it. When the power goes, it switches to battery in 10 ms, and devices do not restart. The built-in stabiliser helps when the grid voltage sags: the station keeps charging at voltages from 100 V.
How long other devices will run
After losses about 815 Wh is usable.
- A 100 W gas boiler with pump: about 8 hours of continuous operation.
- An 80 W TV: about 10 hours.
- A monitor and laptop together at 90 W: about 9 hours.
A boiler runs in cycles, so in practice the reserve is larger.
Ways to charge
From the wall
X-Stream technology charges the station to 80% in about two hours. The built-in stabiliser lets it charge even from a weak grid.
From the sun
According to EcoFlow Ukraine, the DELTA 3 Air stations accept 500 to 1000 W of solar power depending on the model. We will advise on the exact panel layout for the DELTA 3 1000 Air when you order.
Comparison
| Model | Capacity | Power | Weight | |
|---|---|---|---|---|
| DELTA 3 1000 Air | 960 Wh | 500 W | 9.9 kg | |
| [[LINK:new:a2000 | DELTA 3 2000 Air]] | 1920 Wh | 1000 W | 17.8 kg |
| [[LINK:145 | DELTA 3 Classic]] | 1024 Wh | 1800 W | 12.1 kg |
| [[LINK:new:r3mp | RIVER 3 Max Plus]] | 858 Wh | 600 W | 13.3 kg |
The DELTA 3 Classic has a similar capacity and three times the output, so it runs a fridge and microwave. The DELTA 3 1000 Air is chosen for quiet operation, a compact upright body and a 10 ms UPS.
Tips for use
- Place the station so its vents are not blocked.
- The total power of devices must not exceed 500 W.
- During long storage keep the charge at 60-80%.
DELTA 3 1000 Air and outage schedules
With a schedule of 4 hours without power and 4 hours with power, the station charges to 80% while the power is on. Over 4 hours of outage, a router, laptop, monitor and lights together drawing 120 W use about 480 Wh, half the capacity. So the station covers a full working day across two outages in a row, as long as there are a few hours of power between them.
Where to keep the station
The upright body of the DELTA 3 1000 Air takes little space: the station fits under a desk next to a PC tower or by the router in the hallway. At up to 39 dB you can work next to it comfortably. Leave space around the vents.
Why LFP
An LFP battery is stable when hot, ages slowly and is safe for a flat. That is why EcoFlow stresses that DELTA 3 Air stations can be kept in living spaces, unlike a generator, which needs fuel and the outdoors.
EcoFlow app
The station connects to a smartphone over Wi-Fi or Bluetooth. The EcoFlow app shows the remaining charge, input and output power and an estimated run time. You can limit the charging speed so the station runs more quietly at night, set charge and discharge limits for a longer battery life, switch individual outputs off and update the firmware. Over Bluetooth, control works even when the internet is down.
FAQ
Can I keep the station plugged in all the time?
Yes, that is exactly how it works as a UPS: it charges while the power is on and switches to battery instantly when the power goes.
How does the DELTA 3 1000 Air differ from the RIVER 3 Max Plus?
The capacity is similar, around 0.9-1 kWh. The DELTA 3 1000 Air is a single station in an upright body with a 500 W output; the RIVER 3 Max Plus is a station with a battery you can split off and a 600 W output with three sockets.
Can the station run a fridge?
No, 500 W is too little for the compressor start-up current of most fridges. For a fridge choose the DELTA 3 2000 Air or the DELTA 3.
Can the capacity be expanded?
There is no official information about extra batteries for DELTA 3 Air, so treat the capacity as fixed.
How do I buy EcoFlow DELTA 3 1000 Air?
