BLUETTI Elite 300 vs EcoFlow DELTA Pro
Technical comparison · Home backup
Two LFP stations of about 3 kWh for an apartment: 26.3 kg with a no-break output against 45 kg on wheels with far higher output. The choice is between a unit you carry up the stairs and one that runs more large appliances at once (manufacturer-declared values).

The differences that matter
- 10 ms continuity against a 30 ms backup gap → a computer stays on with the first, may reboot with the second.
- 2400 W (4800 peak) against 3600 W (7200 peak) → the second carries more large appliances at the same time.
- 26.3 against 45 kg, no wheels against wheels → the first is lifted, the second is rolled.
- 3.0144 against 3.6 kWh, the second expandable → the second grows with extra batteries.
Which one to choose
Choose BLUETTI Elite 300 if…
you want the home-office PC, NAS and router to keep running without a reboot, because it switches over in 10 ms in continuity (UPS) mode, and you sometimes move it by hand: at 26.3 kg it is a two-trip carry. The trade-off: 2400 W continuous and 2 outlets, so two big loads together push it to the limit, and the warranty is 2 years.
Choose EcoFlow DELTA Pro if…
in a blackout you want the fridge, an induction hob and other loads up to 3600 W running together, across 4 outlets, with the option to add batteries. It has wheels and a handle. What you accept: 45 kg, and backup with a 30 ms gap (EPS), which a running computer may not forgive.
