Technical comparison · Home backup
BLUETTI AC180P and EcoFlow DELTA 3 Max Plus are two LFP power stations with UPS-type backup, meant to keep household appliances running during an outage or off-grid. The deciding factor is output: 1800 W continuous against 3000 W, which sets how many appliances can run at once (manufacturer-declared values).

The differences that matter
- 1800 W vs 3000 W continuous → the ceiling for appliances running at the same time.
- 500 W vs 1000 W solar input → with the same panel area the second can take in more PV power, and it charges from the grid at 2.3 kW against 1.44 kW.
- 1.44 kWh vs 2.048 kWh, 2 outlets vs 4 → at the same load the capacity lasts longer, and more appliances can be plugged in together.
- 16 kg vs 22.1 kg, 5 vs 3 years of warranty → the first is easier to move and has longer cover.
Which one to choose
Choose BLUETTI AC180P if…
you want a 16 kg station you can carry around often and the appliances you run together stay under 1800 W. You accept 1.44 kWh of capacity, 2 mains outlets and a 500 W solar input, so charging from panels tops out at that figure; in return the warranty is 5 years.
Choose EcoFlow DELTA 3 Max Plus if…
you need to run more appliances together, up to 3000 W, on 4 mains outlets, with 2.048 kWh of capacity and a 10 ms switchover. You accept 22.1 kg of weight and a 3-year warranty instead of 5.
