At around 2kWh these two are the default cross-shop for outage backup. They hold nearly the same energy, and everything else about them differs.
All figures come from published manufacturer specifications. Nothing here quotes prices, ratings, discounts or availability.

Product A
EcoFlow
EcoFlow DELTA 2 Max Portable Power Station
Premium ($$$$)
Best for: buyers invested in EcoFlow's expansion ecosystem
A 2048Wh LiFePO4 system with a 2400W inverter and expansion support, aimed squarely at outage backup: enough capacity for a fridge plus electronics for a long evening, with EPS switchover for connected loads.
Product B
BLUETTI
BLUETTI Elite 200 V2 Portable Power Station
Premium ($$$$)
Best for: buyers who want the newest platform and the highest AC output
BLUETTI's current 2kWh flagship-portable: 2073.6Wh of LiFePO4 behind a 2600W inverter with 3900W Power Lifting for resistive loads, plus a fast UPS switchover and app-managed charge control.

2400W vs 2600W
The BLUETTI's 2600W continuous rating, plus 3900W Power Lifting on resistive loads, is the widest appliance compatibility in the 2kWh class here.
EcoFlow answers with X-Boost, which similarly extends resistive-load handling. For motors and electronics, the continuous rating is what counts, and BLUETTI holds the edge.
Generation gap
The Elite 200 V2 is BLUETTI's current platform; the DELTA 2 Max is EcoFlow's previous-generation 2kWh unit. That shows in charge control, switchover and refinement rather than in raw capacity.
Older does not mean bad. The DELTA 2 Max has a long track record and a mature accessory range, which is worth something in a category where firmware matters.
Growing the system
Both accept add-on batteries. EcoFlow's ecosystem is the more established of the two, with more panel and battery options in circulation.
Expansion costs are significant either way, so decide your target capacity before committing to a brand.
Weight and placement
Around 50 lb against around 53 lb — both are placement decisions rather than portability decisions.
Pick where it will sit, how it will be recharged and what will be plugged into it before you pick between the two.
