Differences EcoFlow River 2 Max vs Jackery Explorer 500
Below is a summary of the specifications:
Battery Chemistry, Capacity, and Lifespan
Both the EcoFlow River 2 Max and the Jackery Explorer 500 offer similar battery capacities—512Wh vs. 518Wh, respectively—providing enough energy to power small appliances, laptops, phones, and lights during outdoor trips or power outages. However, their battery chemistry and longevity differ significantly.
The River 2 Max uses LiFePO₄ (LFP) battery technology, which offers over 3,000 full charge cycles before reaching 80% of its original capacity. This translates into roughly 10 years of daily use with minimal degradation. It also improves safety with better thermal stability and tolerance to overcharging or deep discharging.
In contrast, the Explorer 500 uses an older NMC battery, which provides only around 500 cycles to 80% capacity. Over time, this will result in faster capacity degradation, especially under frequent use or heavy load.
Winner: EcoFlow River 2 Max
With a longer lifespan, safer battery chemistry, and superior durability, the River 2 Max clearly leads in battery technology and long-term value.
AC Output and Device Compatibility
Both models are rated for 500W of continuous AC output with a 1,000W surge capacity, enabling them to power a wide range of electronics such as mini-fridges, projectors, laptops, CPAP machines, and fans. They are well-matched for casual home backup and outdoor needs.
The EcoFlow River 2 Max includes two pure sine wave AC outlets, while the Jackery Explorer 500 provides a single AC outlet. This limits simultaneous use of multiple AC-powered devices on the Jackery, especially if both require higher draw.
Furthermore, the River 2 Max supports X-Boost technology, which allows it to run certain appliances that typically exceed 500W by lowering voltage rather than current. This feature adds flexibility for powering resistive loads like hair dryers or electric kettles under specific conditions.
Winner: EcoFlow River 2 Max
With dual AC outputs and X-Boost support, it offers greater appliance compatibility and multi-device convenience.
Charging Speed and Recharging Methods
The EcoFlow River 2 Max leads the category in charging performance, offering 660W AC input, which recharges the battery from 0–100% in just 60 minutes. This is one of the fastest recharge times in the sub-600Wh class and ideal for users who need to top up quickly before heading out.
The Jackery Explorer 500, by comparison, supports only 85W AC input, requiring over 7.5 hours to reach a full charge. While it’s energy-efficient, the slow recharge speed significantly limits flexibility in short-notice or emergency situations.
For solar charging, the River 2 Max accepts up to 220W via MPPT, while the Explorer 500 caps out at 100W. This means the River 2 Max can recharge via solar in approximately 3 hours, while the Jackery would need 8–9 hours under optimal conditions. Both models support 12V car charging.
Winner: EcoFlow River 2 Max
Its lightning-fast AC charging and higher solar input capacity give it a huge advantage for mobile, off-grid, and emergency applications.
Port Variety and Output Options
The EcoFlow River 2 Max features a total of 11 output ports, making it one of the most versatile compact power stations available. It includes two AC outlets, two USB-A ports, one 100W USB-C port, a car cigarette lighter port, and multiple DC5521 outputs. The presence of a high-power USB-C port allows direct charging of laptops, tablets, drones, and more without needing a wall adapter.
The Jackery Explorer 500, while functional, is more limited with just one AC outlet, three USB-A ports, a DC car port, and two DC barrel ports. It lacks USB-C entirely, which limits its compatibility with modern high-power devices and adds the need for conversion accessories.
Winner: EcoFlow River 2 Max
With more output options and a future-ready USB-C port, the River 2 Max offers more flexibility for simultaneous device charging and modern tech gear.
Smart Features and App Control
The EcoFlow River 2 Max integrates seamlessly with the EcoFlow mobile app, accessible via Wi-Fi or Bluetooth. Users can monitor battery status, view power input/output, change charging speed, update firmware, and schedule operations from their smartphone. This remote control adds significant convenience when the device is tucked away in a vehicle, cabin, or tent.
The Jackery Explorer 500 does not support app control or remote monitoring. All controls and status indicators must be accessed physically through the onboard LCD screen and buttons.
Winner: EcoFlow River 2 Max
Its smart app integration adds valuable functionality and convenience for remote monitoring and control.
Portability and Physical Design
Both models weigh just over 6 kg, making them easy to transport. The River 2 Max measures 270 × 260 × 196 mm, while the Explorer 500 is slightly larger at 300 × 193 × 243 mm. Both units feature built-in ergonomic handles and are designed to be carried with one hand.
In terms of design, the River 2 Max has a more compact, modern aesthetic with symmetrical ports and an intuitive user interface. The Explorer 500 uses Jackery’s signature orange-and-grey color scheme, known for rugged outdoor appeal, though it lacks the compactness of EcoFlow’s latest design.
Winner: Tie
Both models are highly portable and easy to carry, with only minor differences in dimension and weight.
