Portable power stations are becoming increasingly popular for a variety of reasons. They’re fantastic 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, choosing the right one can be a bit tricky. Deciding on the appropriate battery capacity and understanding different battery technologies such as Lithium-ion and LiFePO4 can pose challenges to potential buyers.
In this article, we’ll delve into two standout models: the BLUETTI AC180 and the EcoFlow DELTA 2. We aim to compare these units in detail to assist you in selecting the best option that suits your needs. So let’s get straight into it without any further ado.
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 and EcoFlow DELTA 2 models differ slightly in their energy storage capacities, with the former boasting a higher watt-hour (Wh) value of 1,152Wh compared to the latter’s 1024Wh. This spec is vital as it indicates how much power each unit can store.
A higher Wh means that more devices can be powered for longer periods. Therefore, if your energy needs are substantial, you’d benefit from opting for a model like the BLUETTI AC180 with its superior Wh capacity.
Battery Type: Both the BLUETTI AC180 and EcoFlow DELTA 2 utilise LiFePO4 batteries. This indicates that they’re designed for safety and longevity, making them ideal for regular use or important applications. The choice of battery type suggests these units will operate reliably over an extended period.
Life Cycles: The BLUETTI AC180 boasts over 3,500 cycles, while the EcoFlow DELTA 2 offers between 3,000 to 80+%. This indicates that the BLUETTI model may have a longer lifespan before its capacity drops to just 80% of its original charge. Therefore, it could be more cost-effective in the long run.
Expandable Capacity: The EcoFlow DELTA 2 offers the advantage of supporting an additional battery, either a DELTA 2 or DELTA Max, up to 3040Wh. This feature is absent in the BLUETTI AC180 model. The ability to connect extra batteries enhances storage capacity and proves beneficial when power sources are not readily available for longer durations.
AC Output (W): Both the BLUETTI AC180 and EcoFlow DELTA 2 models offer a maximum continuous power output of 1,800W from their AC outlets. This similarity indicates that they can handle high-powered devices such as microwaves or power tools with ease. However, if your requirements exceed this wattage rating, neither model would be suitable for your needs. Therefore, it’s vital to consider the energy demands of your devices before making a decision.
Surge Power (W): Both the BLUETTI AC180 and EcoFlow DELTA 2 models offer a surge power of 2,700W. This indicates that they can both handle high-power demands for short periods, such as when starting up appliances like fridge compressors. There doesn’t appear to be any difference between the two in this regard.
Ports and Outlets
AC Outlets: The BLUETTI AC180 has two 240V/7.5A outlets, while the EcoFlow DELTA 2 boasts four outlets with a voltage range of 220V-240V. This difference in outlet count could be significant if you’re looking to power multiple devices at once. However, it’s also important to ensure that the voltage and amperage match your device requirements.
USB-A Outlets: The BLUETTI AC180 and EcoFlow DELTA 2 both offer USB-A ports for charging low-power devices. However, the BLUETTI model provides four outlets with a higher amperage of 3A, suggesting faster charging times.
In contrast, the EcoFlow model offers two standard outlets at 2.4A and an additional two fast-charge outlets with varying voltages and amperages. This indicates that while it may not charge as quickly on its standard ports, it has more versatility in terms of fast-charging capabilities.
Overall, both models have their strengths depending on whether speed or flexibility is your priority when charging devices.
USB-C Outlets: The BLUETTI AC180 and EcoFlow DELTA 2 both have a maximum output of 100W. However, the DELTA 2 offers more versatility with two outlets and multiple voltage options. This allows for simultaneous charging of various devices, including larger ones like laptops via its USB-C port.
On the other hand, the AC180 only has one outlet which may limit its functionality in comparison to the DELTA 2. Despite this, it still provides efficient charging for smaller devices such as smartphones.
In terms of wattage rating, both models are on par but the additional features of the DELTA 2 give it an edge over the AC180 when considering multi-device charging capabilities.
DC5521 Outlets (5.5mm): The BLUETTI AC180 has a single 12V, 10A outlet while the EcoFlow DELTA 2 offers two outlets with a lower amperage and wattage at 12V/3A, 38W max. This difference could be significant depending on your device’s specific power requirements.
Other DC Outlets: Both the BLUETTI AC180 and EcoFlow DELTA 2 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 high on your list of considerations.
AC Charging (W): The BLUETTI AC180 has a higher maximum power intake at 1,440W compared to the EcoFlow DELTA 2’s 1,200W. This suggests that the BLUETTI model could potentially charge faster. However, it’s important to weigh this against each unit’s total battery capacity for a complete picture of charging efficiency.
DC / Car Charging: The BLUETTI AC180 and EcoFlow DELTA 2 both support a 12V/24V input, making them handy for charging from a car or other DC source. This is particularly useful when on the road or in situations where an AC outlet isn’t available. However, the EcoFlow DELTA 2 has an edge with its higher maximum power output of 1,100W compared to the unspecified max output of the BLUETTI model.
Solar Charging (W): Both the BLUETTI AC180 and EcoFlow DELTA 2 have a maximum solar input of 500W. This indicates that they can both accept the same amount of wattage from solar panels, which is vital for off-grid use or during emergencies.
The similarity in their specs suggests that they would offer comparable speed when it comes to solar charging. No significant differences are noted between these two models based on this specific feature/specification.
Maximum Input (W): The BLUETTI AC180 has a higher input wattage at 1,440W compared to the EcoFlow DELTA 2’s 1100W. This suggests that the BLUETTI model could potentially charge faster due to its greater power acceptance.
Wireless Charging Pad: The BLUETTI AC180 offers a 15W max wireless charging feature, which can be handy for charging smartphones or other devices without the need for cables. In contrast, the EcoFlow DELTA 2 lacks this function, potentially making it less convenient in certain situations.
Smart App Control: Both the BLUETTI AC180 and EcoFlow DELTA 2 models offer smartphone app control, providing users with handy information such as battery status and power input/output. The connection to the app for both units is facilitated through Wi-Fi and Bluetooth, indicating a similarity in their connectivity features.
Warranty: Both the BLUETTI AC180 and EcoFlow DELTA 2 offer a warranty period of five years. This suggests that both manufacturers have a similar level of confidence in their products’ durability and performance. Always ensure to read the fine print, as longer warranties typically indicate better product reliability.
