Output (W)
Both the BLUETTI AC180 and the EcoFlow DELTA 2 have the same continuous output of 1800W output, and the same surge output of 2700W (also referred to as ‘Power Lifting Mode’ by BLUETTI) for higher-demand appliances.
The key difference between BLUETTI AC180 vs EcoFlow DELTA 2 lies in the EcoFlow DELTA 2’s ‘X-Boost technology,’ meaning it prevents overloading from devices up to 2200W.
Outlet options
The BLUETTI AC180 includes 2x AC outlets (240V/7.5A), 1x USB-C outlet (100W max), 4x USB-A outlets (5V/3A), and 1x DC5521 outlet (12V/10A), alongside a car outlet and a 15W max wireless charging pad.
In contrast, the EcoFlow DELTA 2 provides 4x AC outlets (220V-240V), 2x USB-C outlets (100W max), 2x USB-A outlets, and 2x DC5521 outlets (12V/3A, 38W max), alongside a car outlet, but does not feature wireless charging.
Capacity (Wh)
The BLUETTI AC180 has a capacity of 1152Wh, and cannot be scaled up with additional battery units. On the other hand, whilst the EcoFlow DELTA 2 has a lower base capacity of 1024Wh, it does offer expandability of up to 3072Wh total when connected to additional battery units. This feature allows for significant capacity enhancement, ensuring longer usage and greater flexibility in power management.
The following batteries are supported by the EcoFlow DELTA 2 for expanding capacity:
(Please note: whilst the BLUETTI AC180 does not have scalability with additional battery units, it CAN be charged by additional batteries through Power Bank Mode. Compatible batteries include the B80, B230, or B300 batteries. The DC7909 cable is required for connecting the B80 battery, while the P090D cable is required for the B230/B300 batteries.)
Battery
Both the BLUETTI AC180 and the EcoFlow DELTA 2 utilize LiFePO₄ (lithium iron phosphate, or LFP) batteries, which are renowned for their safety and longevity. Whilst slightly heavier than alternatives, these batteries provide a stable power source and are less prone to thermal runaway compared to traditional lithium-ion batteries. The use of LiFePO₄ technology in both units ensures a more durable and reliable performance, making both them excellent choices for extended use in various settings.
Recharging Options and Speed
The BLUETTI AC180 has fast recharging capabilities, recharging from 0-80% in 45 minutes via 1440W AC input, and achieving a full recharge within 1.3-1.8 hours. It can also be recharged fully in under 3 hours via solar panels (with a maximum 500W solar input) in ideal conditions.
The EcoFlow DELTA 2 has very similar charging times, recharging from 0-80% in 50 minutes, and completing a full recharge in under 2 hours. Its solar charging capabilities are similarly efficient, with the potential to fully charge in 3-6 hours depending on solar conditions and panel setup.
Both the BLUETTI AC180 and EcoFlow DELTA 2 can be recharged via AC, car, or solar – both supporting a 12V/24V car input, and maximum 500W solar input.
Charge Life Cycle
Both models have a very similar life cycle, although the BLUETTI AC180 has a slight edge with 3,500+ cycles to 80%, compared to the EcoFlow DELTA 2 at 3,000+ cycles to 80%.
Portability
The BLUETTI AC180 weighs in at 35 lbs (16 kg), making it noticeably heavier than the EcoFlow DELTA 2, which weighs 27 lbs (12 kg).
The AC180 and DELTA 2 are more similarly matched in terms of size, with the AC180 measuring 13.39 x 9.72 x 12.48 inches (340 x 247 x 317 mm) and the DELTA 2 measuring 15.7 x 8.3 x 11 inches (400 x 211 x 281 mm).
However, whilst weight and size are important factors when it comes to portability, it is also important to consider handle design. Whilst both power stations have two handles on the top of the units, the BLUETTI AC180’s handles are much more compact than the DELTA 2’s, whose handles protrude out on either side.
Personally, we prefer the design of the handles on the AC180 as it makes it much easier for things like packing inside a car or storing when not in use – that and the build of the handles just feels a little sturdier than on the DELTA 2.
App Control and Connectivity
Both the BLUETTI AC180 and EcoFlow DELTA 2 offer remote control and connectivity through their respective smartphone apps. Both models’ apps offer control via both Wi-Fi and Bluetooth, and provide options for remote control and real-time monitoring, including insights into battery status, power usage, and the option to control settings such as charging limits and port activation.
Generally, reviews of both models have positive sentiments towards these apps, which are described as being convenient and offering good functionality. The ability to interact with their power stations is particularly useful in outdoor or backup scenarios, although some users noted occasional connectivity issues which required a device restart or app refresh to resolve.
Warranty
Both the BLUETTI AC180 and the EcoFlow DELTA 2 have the same 5-year warranty, which is a significant length of time for portable power stations (many units only have 2-3 years, including other models from both the BLUETTI and EcoFlow brands).
Please note that this warranty is for products purchased from the BLUETTI and EcoFlow websites directly, and may not apply to products purchased from third-party websites, including Amazon. It is for this reason that we always encourage buyers to purchase directly from the brand’s website.
