Differences Bluetti AC300 vs EcoFlow Delta Pro
Below is a summary of the specifications:
Battery Capacity and Expandability
Battery capacity is one of the most critical factors when choosing a power station, as it determines how long it can run essential appliances and electronics.
The EcoFlow Delta Pro comes with an impressive 3,600Wh capacity, making it one of the largest portable power stations on the market. It is expandable up to 25kWh using additional smart batteries, making it ideal for long-term home backup, RV living, and off-grid applications.
On the other hand, the Bluetti AC300 does not have a built-in battery, but it is modular, allowing users to pair it with external Bluetti B300 battery packs. It supports up to four B300 batteries, reaching 12,288Wh, which is an excellent alternative for users who prefer a modular approach.
Winner: EcoFlow Delta Pro
With higher base capacity and greater expandability, the Delta Pro offers a more powerful energy storage solution.

Power Output and Performance
When it comes to power output, both models deliver exceptional continuous and surge power, allowing them to run high-energy appliances and tools.
The EcoFlow Delta Pro provides 3,600W of continuous power and a 7,200W surge capacity, making it ideal for running refrigerators, power tools, air conditioners, and even electric stoves.
The Bluetti AC300 offers 3,000W of continuous output and 6,000W surge capacity, which is slightly lower than the Delta Pro but still powerful enough to run most household and outdoor appliances.
Winner: EcoFlow Delta Pro
With higher continuous and surge output, the Delta Pro takes the lead for users needing extra power.
Charging Speed and Solar Input
Fast charging is crucial for efficient off-grid use. Both power stations offer multiple recharging methods, including AC charging, solar, and vehicle charging.
The Bluetti AC300 supports up to 3,000W of AC charging and 2,400W of solar input, allowing rapid recharging through solar panels. This makes it one of the fastest solar-charging power stations available, ideal for users who rely heavily on renewable energy sources.
The EcoFlow Delta Pro, in contrast, supports up to 1,800W of AC input and 1,600W of solar charging, which is lower than the Bluetti AC300. However, it features EcoFlow’s X-Stream fast charging, which allows a full recharge in 1.9 hours via an AC wall outlet.
Winner: Bluetti AC300
With higher AC and solar input capabilities, the AC300 is the better choice for fast solar recharging.

Portability and Weight
Despite being powerful, both models have significant weight differences, which can impact portability.
The EcoFlow Delta Pro weighs 99 lbs (45 kg) due to its built-in 3,600Wh battery, making it less portable than the Bluetti AC300. However, it features built-in wheels and a retractable handle, making it easier to move despite its weight.
The Bluetti AC300, weighing 47.6 lbs (21.6 kg), is much lighter but requires external batteries to function. This modularity adds flexibility but can also be less convenient for users who prefer an all-in-one power solution.
Winner: Bluetti AC300
For lightweight and modular power solutions, the AC300 is the better option.
Durability and Battery Lifespan
Both power stations use LiFePO₄ (LFP) battery chemistry, offering long lifespans and high safety standards.
Each model is rated for 3,500+ cycles before reaching 80% of its original capacity, ensuring years of reliable use.
Winner: Tie
Both models feature long-lasting LiFePO₄ battery technology.
