Portable power stations are a fantastic investment for a variety of reasons. They’re ideal for camping trips, providing a reliable source of power in the great outdoors. Additionally, they serve as an emergency backup during unexpected power outages.

However, selecting the right model can be challenging. Potential buyers often grapple with understanding battery capacities and differentiating between battery technologies such as Lithium-ion and LiFePO4.

In this article, we’ll delve into two popular models: the BLUETTI EB55 and the EcoFlow DELTA mini. We aim to provide an in-depth comparison to assist you in choosing the most suitable option for your needs. Stay tuned as we dissect these two units 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 EB55 and the EcoFlow DELTA mini differ significantly in their energy storage capacities. The former has a capacity of 537Wh, while the latter boasts a more substantial 882Wh.

This difference indicates that the DELTA mini can power more devices for longer periods compared to the EB55. Therefore, if your energy needs are high, you’d be better off opting for a model with higher Wh like the DELTA mini.

Battery Type: The BLUETTI EB55 utilises a LiFePO4 battery, renowned for its safety and extended life cycles. This makes it an excellent choice for regular use or applications where reliability is paramount. In contrast, the EcoFlow DELTA mini employs a standard Lithium-ion NCM battery which typically offers higher energy density but may not last as long.

Understanding the type of battery used can give you an idea of how durable the unit will be and how safely it’ll function.

Life Cycles: The BLUETTI EB55 offers a significantly higher number of cycles, over 2,500 to reach 80% capacity. In contrast, the EcoFlow DELTA mini provides around 800 cycles before hitting this mark. This indicates that the BLUETTI model may have a longer lifespan and could potentially offer more value for money over time.

Expandable Capacity: Both the BLUETTI EB55 and EcoFlow DELTA mini lack this feature. This means neither model allows for additional battery connection to boost storage capacity, which could be a drawback in situations where prolonged access to power isn’t available. The absence of this function highlights a potential limitation in both models’ versatility and adaptability.

Power Output

AC Output (W): The BLUETTI EB55 offers a maximum continuous power output of 700W from its AC outlets. On the other hand, the EcoFlow DELTA mini doubles that with an impressive 1400W. If you’re looking to run high-powered devices such as microwaves or power tools, the latter would be your best bet due to its higher wattage rating. Remember, it’s all about matching your energy needs with the right product specs.

Surge Power (W): The BLUETTI EB55 and EcoFlow DELTA mini differ significantly in their surge power capabilities. The EB55 can supply a short burst of 1,400W, while the DELTA mini outperforms it with a capacity of 2,100W. This difference could be significant depending on the demands of your devices during start-up.

Ports and Outlets

AC Outlets: Both the BLUETTI EB55 and EcoFlow DELTA mini models feature two AC outlets. This means you can power a couple of devices at once with either unit.

The voltage range for the BLUETTI is 220V-240V, while the EcoFlow operates at a fixed 230V. It’s essential to ensure these specs align with your device requirements before use.

In terms of similarities, both units offer dual outlet functionality which is handy for multi-device usage. However, there’s a slight difference in their voltage specifications that could impact compatibility with certain appliances or gadgets.

USB-A Outlets: The BLUETTI EB55 and EcoFlow DELTA mini both offer USB-A ports for charging low-power devices. However, the EB55 provides four outlets with a higher amperage of 3A, suggesting faster and more versatile charging capabilities.

On the other hand, while the DELTA mini has fewer outlets at lower amperages (2.4A), it does feature an additional fast charge outlet. This could potentially provide quicker charging for compatible devices despite its overall lower specs compared to the EB55.

USB-C Outlets: Both the BLUETTI EB55 and EcoFlow DELTA mini models have a single outlet with a maximum output of 100W. This indicates that they can both handle charging larger devices such as laptops, thanks to their USB-C compatibility. However, the number of ports available for simultaneous device charging isn’t specified in this information.

DC5521 Outlets (5.5mm): Both the BLUETTI EB55 and EcoFlow DELTA mini models offer two DC outlets, which are handy for certain electronic devices and smaller appliances. However, there’s a significant difference in their output; the BLUETTI EB55 provides 12V at 10A while the EcoFlow DELTA mini delivers 12.6V but only at 3A. This could impact how quickly your devices charge or operate when connected to these power stations.

Other DC Outlets: Both the BLUETTI EB55 and EcoFlow DELTA mini models feature a single car outlet. This is particularly useful for charging devices that utilise car chargers or specialised plugs. If you own such gadgets, this attribute should be taken into account when choosing between these two models.

Charging Options

AC Charging (W): The BLUETTI EB55 has a maximum power intake of 200W, while the EcoFlow DELTA mini can accept up to 900W. This suggests that the DELTA mini would 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.

DC / Car Charging: The BLUETTI EB55 and the EcoFlow DELTA mini both support 12/24V charging from a Cigarette Lighter Port, making them suitable for on-the-go charging during road trips or when an AC outlet isn’t available. However, there’s a slight difference in their maximum amperage. The BLUETTI EB55 can handle up to 8.3A while the EcoFlow DELTA mini maxes out at 8A.

Solar Charging (W): The BLUETTI EB55 has a maximum solar input of 200W, while the EcoFlow DELTA mini can accept up to 300W. This difference indicates that the DELTA mini may charge faster from solar panels, particularly useful for off-grid use or emergencies.

Maximum Input (W): The BLUETTI EB55 has a 400W input capacity, accepting charge from AC+Solar or Dual AC. In contrast, the EcoFlow DELTA mini boasts a higher input wattage of 900W from its AC source. This difference in power intake could potentially lead to faster charging times for the DELTA mini.

Convenience Features

Wireless Charging Pad: The BLUETTI EB55 offers a 15W max wireless charging feature, which allows for the convenient charging of smartphones and other devices without the need for cables. In contrast, the EcoFlow DELTA mini does not provide this function. This difference could be significant depending on individual user needs and preferences.

Smart App Control: The BLUETTI EB55 doesn’t offer app control or monitoring, unlike the EcoFlow DELTA mini. This difference could impact user convenience and access to real-time information about the unit’s performance.

In terms of connectivity, the EcoFlow DELTA mini uses both Wi-Fi and Bluetooth. The BLUETTI EB55 does not provide any such specifications, suggesting it lacks this feature altogether.

Warranty

Warranty: Both the BLUETTI EB55 and EcoFlow DELTA mini offer a 2-year warranty. This suggests that both manufacturers have a similar level of confidence in their products’ durability and performance. Always remember to check the fine print, as longer warranties typically indicate superior product quality.
