Differences Between Bluetti AC180 vs EcoFlow Delta 2
Below is a summary of the specifications:




Battery Capacity and Expandability
The Bluetti AC180 comes with a 1,152Wh LiFePO₄ battery, delivering over 3,500 charge cycles before degrading to 80% capacity. This makes it one of the most durable options in its class. However, it does not support expansion, so its power is limited to the built-in storage.
In contrast, the EcoFlow Delta 2 features a slightly smaller 1,024Wh LiFePO₄ battery rated for 3,000 cycles. While its base capacity is lower, it offers expandability up to 3,040Wh when paired with two external batteries, making it a better choice for those who want long-term scalability.
Winner: EcoFlow Delta 2 — although the AC180 has a larger base capacity and longer cycle life, Delta 2’s expandability provides greater flexibility.

Power Output and Device Compatibility
Both units deliver 1,800W AC output, which is enough to run refrigerators, microwaves, power tools, and medical devices. The Bluetti AC180 offers 4 AC outlets, 2 USB-A ports, 1 USB-C (100W), 1 car DC outlet, and a wireless charging pad, which is a unique feature for topping up phones conveniently. Its surge capacity reaches 2,700W, giving it the edge for high-draw appliances.
The EcoFlow Delta 2 offers 6 AC outlets, 2 USB-A ports, 2 USB-C (100W), and 1 car DC outlet. It lacks wireless charging but provides more AC outlets and dual USB-C ports, which is ideal for powering multiple laptops and high-demand devices at once. Its surge handling of 2,400W is slightly lower than Bluetti’s.
Winner: Tie — Bluetti provides higher surge power and wireless charging, while EcoFlow offers more outlets and dual USB-C ports.
Charging Speeds and Solar Integration
Bluetti equips the AC180 with 1440W turbo AC charging, allowing a full recharge in around 1.3 hours. It also supports up to 500W solar input, enabling users to fully recharge in about 3 hours under ideal sunlight conditions.
The EcoFlow Delta 2 uses X-Stream fast charging with a 1200W input, recharging in about 1.2 hours. It also supports up to 500W solar input, giving it similar off-grid performance.
Winner: EcoFlow Delta 2 — slightly faster AC recharge, though solar performance is evenly matched.

Design, Portability, and Build Quality
At 35.2 lbs (16 kg), the Bluetti AC180 is heavier, making it less portable for frequent travel. However, its design includes sturdy handles, reinforced casing, and effective cooling ventilation, making it well-suited for rugged environments.
The EcoFlow Delta 2, at 27 lbs (12 kg), is significantly lighter and easier to carry. It retains robust build quality with reinforced corners, a compact frame, and well-placed ventilation. Its lighter weight makes it more appealing for RVs, camping, and frequent mobility.
Winner: EcoFlow Delta 2 — lighter and more portable without compromising durability.
Smart Features and App Integration
The Bluetti AC180 connects to the Bluetti App via Wi-Fi or Bluetooth, offering real-time monitoring, power control, charging schedules, and firmware updates. Its app ecosystem is straightforward and user-friendly.
The EcoFlow Delta 2 integrates with the EcoFlow App, which provides similar features but adds more customization options such as intelligent charging control, remote diagnostics, and compatibility with EcoFlow’s ecosystem of smart devices.
Winner: EcoFlow Delta 2 — while both offer app integration, EcoFlow’s ecosystem is more advanced and interconnected.
