Portable power stations are becoming increasingly popular, and for good reason. They offer a reliable source of power for camping trips or as an emergency backup during unexpected blackouts. However, choosing the right one can be a bit tricky.
Understanding battery capacity and the different types of battery technology, such as Lithium-ion versus LiFePO4, can be challenging for some. That’s why we’re here to help you make an informed decision.
In this article, we’ll be comparing two top models: the BLUETTI AC180 and the EcoFlow DELTA Max. We’ll delve into their features in detail to assist you in selecting the best option that suits your needs. So stay tuned for a comprehensive comparison without any unnecessary jargon or fluff.
Before diving in, we recommend you check out the helpful comparison tables on the Bluetti and EcoFlow websites to get a feel for where these products sit in their line-up:
Battery Specs and Features
Battery Capacity (Wh): The BLUETTI AC180 has a capacity of 1,152Wh while the EcoFlow DELTA Max boasts a higher energy storage at 2016Wh. This spec indicates the amount of energy each device can hold, measured in watt-hours. A larger figure means you can power more devices for longer periods. For those with high energy needs, a model with greater Wh would be beneficial.
Battery Type: The BLUETTI AC180 utilises a LiFePO4 battery, renowned for its safety and extended lifespan. This makes it an excellent choice for regular use or vital applications. Conversely, the EcoFlow DELTA Max employs a standard Lithium-ion NCM battery, which typically provides higher energy density but may not last as long.
Understanding the type of battery used can give you insight into how durable the unit will be and how safely it’ll function.
Life Cycles: The BLUETTI AC180 boasts over 3,500 cycles, significantly outperforming the EcoFlow DELTA Max which offers only 800 cycles to reach an 80% capacity. This indicates that the BLUETTI’s battery longevity is superior and could provide better value for money over time. The disparity in cycle count between these two models highlights a key difference in their respective performances.
Expandable Capacity: The EcoFlow DELTA Max offers the ability to connect additional batteries, boosting its total storage capacity up to 6kWh. This feature is absent in the BLUETTI AC180 model. The added flexibility of extra power storage makes the EcoFlow a standout choice for prolonged periods without access to an external power source.
AC Output (W): The BLUETTI AC180 offers a maximum continuous power output of 1,800W from its AC outlets. On the other hand, the EcoFlow DELTA Max provides a higher wattage rating at 2400W. If you’re intending to operate high-powered appliances such as microwaves or power tools, the latter would be more suitable due to its superior wattage capacity. The key difference between these two models lies in their respective power outputs.
Surge Power (W): The BLUETTI AC180 offers a surge power of 2,700W, while the EcoFlow DELTA Max provides a significantly higher output at 4600W. This difference indicates that the DELTA Max can handle more demanding start-up loads from appliances such as fridge compressors. Therefore, in terms of surge power capacity, the EcoFlow model outperforms its BLUETTI counterpart.
Ports and Outlets
AC Outlets: The BLUETTI AC180 has two 240V/7.5A outlets, while the EcoFlow DELTA Max boasts four 230V outlets. This difference in outlet count means that the DELTA Max can power more devices at once compared to the AC180. However, it’s important to note that both models offer different voltage and amperage levels, so you’ll need to ensure these match your device requirements before choosing a model.
USB-A Outlets: The BLUETTI AC180 offers four outlets with a 5V, 3A spec, providing more charging options and faster power delivery. In contrast, the EcoFlow DELTA Max has two standard outlets at 5V, 2.4A and an additional two fast-charge ports. This suggests that while the Delta Max may not offer as many standard ports or as high amperage, it does provide versatility with its fast-charging feature.
USB-C Outlets: The BLUETTI AC180 and EcoFlow DELTA Max both have a maximum output of 100W. However, the DELTA Max has an advantage with two outlets compared to the single outlet on the AC180. This allows for simultaneous charging of multiple devices.
Both models support USB-C, which is beneficial for charging larger devices such as laptops alongside smartphones. The wattage rating indicates that both can charge devices at a swift pace. Yet again, the additional port on the DELTA Max provides more flexibility in device charging.
DC5521 Outlets (5.5mm): The BLUETTI AC180 has a single 12V, 10A outlet while the EcoFlow DELTA Max offers two outlets with variable voltage and a maximum of 5A. This indicates that the EcoFlow model provides more flexibility in terms of power output, but potentially less current per outlet.
These DC outlets are particularly handy for certain electronic devices and smaller appliances. It’s worth checking if your gadgets require this specific type of connection.
Other DC Outlets: Both the BLUETTI AC180 and EcoFlow DELTA Max models feature a single car outlet. This is particularly useful for charging devices that require specialised plugs or car chargers. If you utilise such devices, this aspect should be taken into account when choosing between these two models.
AC Charging (W): The BLUETTI AC180 has a maximum power input of 1,440W, while the EcoFlow DELTA Max can accept up to 2000W. This suggests that the DELTA Max could potentially charge faster due to its higher wattage acceptance. However, it’s important to weigh this against each unit’s total battery capacity for a complete understanding of their charging efficiency.
DC / Car Charging: The BLUETTI AC180 and the EcoFlow DELTA Max both support 12V/24V, indicating they can be charged from a car or other DC source. This feature is particularly handy for road trips or situations where an AC outlet isn’t accessible. However, it’s worth noting that the EcoFlow model specifies an 8A limit, which isn’t mentioned for the BLUETTI model.
Solar Charging (W): The BLUETTI AC180 has a maximum solar input of 500W, while the EcoFlow DELTA Max can accept up to 800W. This indicates that the DELTA Max could potentially charge faster from solar panels, which might be beneficial for off-grid use or during emergencies.
Maximum Input (W): The BLUETTI AC180 has a maximum input wattage of 1,440W while the EcoFlow DELTA Max can accept up to 2000W. This suggests that the DELTA Max may charge faster due to its higher capacity for power intake.
Wireless Charging Pad: The BLUETTI AC180 offers a 15W max wireless charging feature, which is absent in the EcoFlow DELTA Max. This allows for handy, cordless charging of smartphones and other compatible devices.
Smart App Control: Both the BLUETTI AC180 and EcoFlow DELTA Max models can be controlled or monitored via a smartphone app, offering additional convenience. They both connect to the app through Wi-Fi and Bluetooth, providing real-time data such as battery status and power input/output. There’s no significant difference between the two in this regard; they’re on par with each other when it comes to connectivity features.
Warranty: The BLUETTI AC180 offers a warranty period of 5 years, while the EcoFlow DELTA Max provides a 2-year warranty that can be extended to 3 years with product registration. This suggests that BLUETTI may have more faith in their product’s longevity and reliability. However, it’s always wise to scrutinise the terms and conditions of any warranty for potential limitations or exclusions.
