Quick answer: The BLUETTI AC180 (1,152Wh) has 128Wh more nominal capacity than the EcoFlow DELTA 3 Plus (1,024Wh); both list 1,800W continuous AC output. That capacity gap changes modeled runtime modestly. Weight, charging, price for equivalent bundles and your own loads should decide.
Energy is only one part of the choice
The nominal capacity difference here is 128Wh. Under identical assumptions that changes energy duration, but actual delivered energy also depends on efficiency, internal consumption and operating conditions. Do not interpret a modeled difference as a laboratory result.
Check the load before comparing runtime
A higher continuous rating can matter for simultaneous appliances. It does not establish whether a compressor will start or whether every outlet can carry that load. Check the exact manual, running requirements and surge behavior.
Make the purchase comparison personal
Compare current delivered prices for equivalent bundles. Check weight, charging compatibility, return conditions and support for the seller and location you will use. This page does not declare a universal winner: the right choice depends on your loads and charging plan.
