Portable power stations are a fantastic investment for many 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 at home.

However, selecting the right one can be a bit tricky. You might struggle with determining the battery capacity you need or understanding different battery technologies like Lithium-ion and LiFePO4.

In this article, we’ll delve into two popular models: the EcoFlow DELTA mini and the EcoFlow RIVER 2 Pro. We aim to compare these two units in detail to assist you in choosing the best option that suits your needs perfectly.

Before diving in, we recommend you check out the helpful comparison table on the EcoFlow website to get a feel for where these products sit in their line-up, particularly in relation to their newly released models.

Battery Specs and Features

Battery Capacity (Wh): The EcoFlow DELTA mini boasts a capacity of 882Wh, while the EcoFlow RIVER 2 Pro sits slightly lower at 768Wh. This spec is significant as it indicates the energy storage capability of each device, measured in watt-hours. A higher figure suggests that more devices can be powered for longer periods. For those with hefty energy requirements, a model with greater Wh would be beneficial.

Battery Type: The EcoFlow DELTA mini utilises an NCM battery, known for its high energy density. This could potentially offer more power output but might not last as long. In contrast, the EcoFlow RIVER 2 Pro uses a LiFePO4 battery.

This type of battery is renowned for its safety and longevity, making it ideal for regular use or important applications. Therefore, understanding the type of battery can give you an idea about the unit’s lifespan and operational safety.

Life Cycles: The EcoFlow DELTA mini offers 800 cycles to 80%, while the EcoFlow RIVER Pro 2 provides a significantly higher number of cycles at 3000 to reach the same capacity. This indicates that the RIVER Pro 2’s battery has a longer lifespan before it needs replacement, offering potentially better value over time. The cycle count is an indicator of durability and longevity in these models, with the RIVER Pro 2 clearly outperforming its counterpart.

Expandable Capacity: Both the EcoFlow DELTA mini and the EcoFlow RIVER 2 Pro lack this feature. This means they don’t offer the flexibility of expanding their storage capacity by connecting extra batteries. It’s a bit of a letdown, especially for those situations where you’re off-grid for longer periods.

Power Output

AC Output (W): The EcoFlow DELTA mini boasts a higher wattage rating at 1400W, compared to the EcoFlow RIVER 2 Pro’s 800W. This indicates that the DELTA mini can handle more power-demanding devices like microwaves or power tools. On the other hand, the RIVER 2 Pro might be better suited for less energy-intensive appliances. The key difference here is their capacity to support high-powered devices due to their respective wattage ratings.

Surge Power (W): The EcoFlow DELTA mini, with its 2100W capacity, can provide a higher surge power compared to the EcoFlow RIVER 2 Pro which offers 1600W. This indicates that the DELTA mini is more capable of handling devices requiring high initial power bursts such as fridge compressors. Therefore, in terms of surge power capabilities, the DELTA mini outperforms the RIVER 2 Pro.

Ports and Outlets

AC Outlets: The EcoFlow DELTA mini and the EcoFlow RIVER 2 Pro both offer 230V AC outlets, but differ in quantity. The DELTA mini has two outlets, while the RIVER 2 Pro provides three. This means you can power more devices at once with the RIVER 2 Pro, provided your gadgets are compatible with its voltage and amperage.

USB-A Outlets: The EcoFlow DELTA mini and the RIVER 2 Pro both offer USB-A ports for charging low-power devices. However, the DELTA mini provides more outlets with higher amperage, suggesting a faster and more versatile charging experience.

On the other hand, while the RIVER 2 Pro has fewer outlets, it still offers sufficient power for most small device needs. The key difference lies in their capacity to charge multiple devices simultaneously or deliver quicker charging times.

In summary, if you’re after speed and versatility in your device charging capabilities, then the DELTA mini appears to be your go-to option. But if you only need to charge one or two devices at a time without urgency, then the RIVER 2 Pro should suffice.

USB-C Outlets: Both the EcoFlow DELTA mini and RIVER 2 Pro models have a single outlet with a maximum output of 100W. This suggests that they can charge larger devices such as laptops, in addition to smartphones, at an equal rate. The key difference lies in the voltage range offered by the RIVER 2 Pro model, which provides more flexibility for charging various devices.

DC5521 Outlets (5.5mm): The EcoFlow DELTA mini offers two 12.6V, 3A outlets while the EcoFlow RIVER Pro only has one outlet with the same specs but a max of 36W. This difference could be significant depending on your device requirements and usage needs.

Both models provide specialised DC outlets which are handy for certain electronic devices and smaller appliances. It’s worth checking if any of your gadgets require this type of outlet to determine which model is more suitable for you.

Other DC Outlets: Both the EcoFlow DELTA mini and the EcoFlow RIVER 2 Pro models come equipped with a single car outlet. This feature is particularly handy for those who utilise devices that require car chargers or specialised plugs.

Charging Options

AC Charging (W): The EcoFlow DELTA mini has a slightly higher maximum power intake at 900W, compared to the EcoFlow RIVER 2 Pro’s 870W. This suggests that the DELTA mini may charge marginally quicker from a wall outlet. However, it’s important to weigh this against each unit’s total battery capacity for an accurate comparison.

DC / Car Charging: Both the EcoFlow DELTA mini and RIVER 2 Pro support a voltage of 12V/24V with an amperage max of 8A. However, there’s a difference in their maximum power output; while the DELTA mini doesn’t specify this, the RIVER 2 Pro can reach up to 100W. This feature indicates that both units can be charged from a car or other DC source, which is quite handy for road trips or situations where an AC outlet isn’t available.

Solar Charging (W): The EcoFlow DELTA mini has a higher maximum wattage intake at 300W, compared to the EcoFlow RIVER 2 Pro’s 220W. This suggests that the DELTA mini would charge faster from solar panels, making it potentially more efficient for off-grid use or in emergencies.

Maximum Input (W): The EcoFlow DELTA mini has a slightly higher input wattage at 900W AC, compared to the EcoFlow RIVER 2 Pro which maxes out at 870W. This difference suggests that the DELTA mini could potentially charge faster due to its ability to accept more power from charging sources.

Convenience Features

Wireless Charging Pad: Both the EcoFlow DELTA mini and the EcoFlow RIVER 2 Pro lack wireless charging capabilities. This feature, while handy for charging smartphones or other devices without cords, isn’t essential to all users.

Smart App Control: Both the EcoFlow DELTA mini and RIVER 2 Pro models can be controlled or monitored via a smartphone app. This feature provides users with handy information such as battery status and power input/output details.

In terms of connectivity, both units utilise Wi-Fi and Bluetooth to connect to the app. This ensures a versatile range of connection options for user convenience.

Warranty

Warranty: The EcoFlow DELTA mini offers a 2-year warranty, while the EcoFlow RIVER 2 Pro provides a more extended period of assurance at 5 years. This difference in warranty length may reflect the manufacturer’s faith in each product’s durability and reliability. Always remember to scrutinise the fine print despite longer warranties typically being more favourable.
