Differences EcoFlow River 2 vs Jackery Explorer 300
Below is a summary of the specifications:
Battery Capacity, Expandability, and Battery Lifespan
The Jackery Explorer 300 offers a slightly larger battery at 293Wh, while the EcoFlow River 2 comes in at 256Wh. On the surface, the Jackery appears to have an edge in raw capacity, but deeper examination reveals the River 2 holds a considerable advantage in battery technology and durability.
The River 2 is built with LiFePO₄ (LFP) battery chemistry, delivering 3,000+ charge cycles to 80% capacity. This means it can be charged and discharged daily for nearly a decade before significant degradation occurs. The LFP battery also enhances thermal stability, safety, and long-term performance in various climates and usage conditions.
The Jackery Explorer 300 uses NMC battery chemistry, which, while energy-dense, offers only 500 cycles to 80%, making it far less durable under repeated use. This is a major drawback for users who plan to use their power station frequently or as part of a solar-based routine.
Neither unit supports battery expansion, so users must choose based on the available internal capacity and expected lifespan.
Winner: EcoFlow River 2
With LFP chemistry and six times the cycle life of the Jackery, the River 2 is the superior long-term energy solution despite having slightly lower capacity.
Power Output and Appliance Compatibility
Both the River 2 and the Explorer 300 feature 300W of continuous AC output, enabling them to power low- to mid-demand electronics like laptops, routers, cameras, lighting, projectors, CPAP machines, or mini fans. The River 2 has a surge capacity of 600W, slightly higher than the Jackery’s 500W surge, which offers better protection when starting motor-driven appliances or handling quick demand spikes.
The River 2 is equipped with two AC outlets, while the Jackery Explorer 300 includes only one. This gives the River 2 more flexibility for simultaneous device use.
Additionally, EcoFlow’s X-Boost technology enables the River 2 to run certain appliances rated up to 600W by dynamically adjusting voltage, offering a real-world advantage when powering resistive loads.
Winner: EcoFlow River 2
It offers greater surge capacity, more AC ports, and better appliance flexibility, delivering stronger overall performance in daily scenarios.
Charging Speed and Solar Input
The charging capabilities of the EcoFlow River 2 are unmatched in its class. With 360W AC input, it can recharge from 0–100% in just 60 minutes. This is ideal for users who need quick turnarounds during travel, emergencies, or short stopovers between activities.
In contrast, the Jackery Explorer 300 offers only 90W AC input, resulting in a much slower 4.5-hour full recharge time. This difference becomes even more significant for users relying on short power windows or time-limited charging setups.
On the solar front, both units support MPPT charging. The River 2 accepts up to 110W of solar input, and the Explorer 300 supports 100W. Charging times depend on sunlight and panel quality but typically range from 3 to 6 hours. However, EcoFlow’s broader voltage range and advanced MPPT controller offer slightly better efficiency in variable solar conditions.
Winner: EcoFlow River 2
With 4x faster AC charging and slightly better solar input performance, the River 2 is the superior option for fast and flexible recharging.
Portability and Form Factor
The Jackery Explorer 300 weighs just 3.2 kg, while the EcoFlow River 2 weighs 3.5 kg. Both are highly portable and easy to carry with a single hand, making them ideal for camping, drone shoots, mobile workstations, or road trips.
In terms of dimensions, the Jackery is slightly narrower and more compact, making it easier to stow in smaller compartments or backpacks. Its orange-and-grey design emphasizes ruggedness and outdoor appeal.
The River 2 is slightly larger but remains very manageable. It features a clean, modern aesthetic with a more symmetrical layout and an intuitive front-facing screen.
Winner: Jackery Explorer 300
Slightly lighter and more compact, the Explorer 300 holds a marginal edge in pure portability, though both are travel-friendly.
Connectivity and Smart Features
The EcoFlow River 2 features Wi-Fi and Bluetooth connectivity, fully compatible with the EcoFlow mobile app. This enables remote monitoring of battery levels, real-time power flows, input/output stats, and firmware updates. Users can even schedule charging times or adjust charge speeds based on power source limitations.
The Jackery Explorer 300 does not support any wireless connectivity. All controls are manual and limited to the built-in LCD screen, which shows only basic battery and port status.
Winner: EcoFlow River 2
App integration and wireless control provide added functionality and convenience, especially for users deploying power stations in remote or hard-to-access areas.
Ports and Output Variety
The EcoFlow River 2 includes a practical and modern array of outputs. It features two AC outlets, two USB-A ports, one 60W USB-C port, a 12V/10A car socket, and a DC5521 output. The presence of a 60W USB-C PD port allows for direct laptop charging without needing adapters.
The Jackery Explorer 300 offers one AC outlet, two USB-A ports, one 60W USB-C port, and one 12V/10A car port. While functional, the port count is more limited, and the lack of a second AC outlet restricts its ability to support multiple AC-powered devices simultaneously.
Winner: EcoFlow River 2
With more output options, including dual AC outlets and the same high-speed USB-C capability, the River 2 provides better versatility for device charging.
