Power & Performance

Both the Bluetti AC180 and EcoFlow Delta 2 offer 1800W continuous AC output with a 2700W surge capacity, suitable for powering appliances like microwaves, fridges, or power tools.

However, EcoFlow is known for its X-Boost mode that can power some high-wattage devices beyond its rated capacity, making it more flexible in real-world usage.

Battery Capacity & Cycle Life


The Bluetti AC180 holds a slight edge in capacity at 1152Wh compared to Delta 2’s 1024Wh. However, both use LiFePO4 cells with excellent longevity:

  • AC180: 3,500+ cycles to 80%
  • Delta 2: 3,000+ cycles to 80%

In practical terms, both batteries should last several years of regular use.

Output Ports & Expandability

The EcoFlow Delta 2 wins on ports and flexibility:

  • 6 AC outlets vs. Bluetti’s 4
  • 2 USB-C ports (100W) vs. Bluetti’s single USB-C
  • Expandable up to 3040Wh with EcoFlow Smart Extra Battery

If you need more ports or plan to scale your system, Delta 2 is the better choice.

Portability & Weight

At just 27 lbs, the EcoFlow Delta 2 is much lighter than the 37.4-lb Bluetti AC180, making it more portable for camping or vehicle use.

Both offer integrated handles, but EcoFlow’s more compact footprint is ideal for mobile users.

Charging Options

Charging speed is nearly identical:

  • AC Input: Bluetti can accept 1440W vs. Delta 2’s 1200W—both charge in ~1.3 hours.
  • Solar Input: Both max out at 500W.
  • Car Charging: Both support 12V/24V input for on-the-go use.

EcoFlow’s software and app integration also allows advanced charging schedules and firmware updates via Wi-Fi/Bluetooth.

Price & Value

  • Bluetti AC180 generally retails between $749–$899
  • EcoFlow Delta 2 often priced around $899–$999, with deals occasionally dropping below $800

The AC180 provides better value if you want slightly more capacity and don’t need expandability. Delta 2 offers more ports, modular expandability, and app controls—justifying the higher price for more tech-savvy users.


Final Verdict: Which One Should You Choose?

  • Choose the Bluetti AC180 if you want more capacity per dollar, a durable LiFePO4 battery, and don’t need expandability or lots of ports.
  • Choose the EcoFlow Delta 2 if you value expandability, more output ports, and lighter weight for portability.

For RVers, digital nomads, and tech-focused users, Delta 2 is the better all-around unit. For budget-conscious backup power at home, the AC180 is a solid pick.


FAQs

Can the EcoFlow Delta 2 be expanded with other EcoFlow batteries?
Yes, it supports the EcoFlow Smart Extra Battery (1024Wh) and the Delta Max battery (2016Wh), up to 3040Wh total.

Does the Bluetti AC180 support app control?
Yes, via the Bluetti app using Bluetooth or Wi-Fi.

Can both models charge and discharge at the same time?
Yes, both support pass-through charging for all ports.
