When it comes to choosing a portable power station, the market offers a plethora of options to fit different needs and preferences. Among these, the EcoFlow River 2 and the Bluetti AC2A stand out as two of the more popular models. In this article, we’ll delve into a detailed comparison of their technical specifics to help you determine which power station maintains the edge for your particular requirements.
Design and Portability
Starting with the form factor, both the EcoFlow River 2 and Bluetti AC2A feature compact and lightweight designs. The River 2 weighs in at a mere 7.7 lbs and measures 245 x 215 x 145mm, whereas the AC2A is marginally heavier at 7.9 lbs with dimensions of 250mm x 156.5mm x 174.5mm. This makes both units highly portable and suitable for outdoor activities where power needs to be moved around frequently.
Battery and Capacity
The lifeblood of any portable power station is its battery capacity, and it’s here we begin to see discernible differences between the two models.
The EcoFlow River 2 boasts an advanced Lithium-ion battery with a TBD capacity in Wh, making it capable of a full charge in just 1 hour. On the other hand, the Bluetti AC2A comes with a 204.8Wh Lithium Iron Phosphate (LiFePO4) battery. The River promises a remarkable recharge cycle life of over 3000 cycles at 80% capacity, mirroring the durability offered by the Bluetti AC2A.
Charging and Output Options
Both models support various output options, but there are nuances to consider. The River 2 offers USB-C and USB-A outputs, a DC Output, and an AC Output that delivers pure sine wave power, which is particularly sensitive for electronics. The Bluetti AC2A houses 2 AC outlets, a 100W USB-C port, USB-A ports, and a regulated car outlet, marking an equivalent range of options for device charging.
Input and Recharge Times
One of the paramount concerns with portable power stations is how quickly they can be recharged. The River 2’s recharge efficiency is a standout feature, capable of a full charge in just 1 hour via its multiple input ports. The Bluetti AC2A is not far behind, offering a full recharge in approximately 1.2 hours when using the 270W AC input or around 1.5 hours with optimal solar input.
