TL;DR: Choose EcoFlow River 2 if charging speed matters most (0→100% in 60 minutes, $179). Choose Jackery Explorer 300 Plus if you need more capacity and quieter operation (288Wh, ≤45dB, $199).

Quick Comparison Table

1. Battery Capacity & Power Output

Winner: Jackery (slight edge)

Both power stations deliver 300W continuous output and 600W surge, sufficient for most small appliances:

The Jackery's 288Wh provides 32Wh more than the EcoFlow's 256Wh—about 12% extra capacity. In extended use, this extra capacity means: 30-60 additional minutes of CPAP runtime, 1-2 more phone charges, or an extra half hour of emergency power.

For daily commuter backup or light camping, 256Wh is sufficient. But if you need longer runtime, the 288Wh Jackery is the better choice.

2. Charging Speed

Winner: EcoFlow River 2 (decisive)

This is where the two stations diverge most dramatically. The EcoFlow River 2 supports up to 360W AC fast charging, going from 0 to 100% in just 60 minutes—twice as fast as the Jackery.

EcoFlow's charging speed advantage shines in these scenarios: last-minute trip decisions (top up an hour before departure), power outage emergencies (rapid recharge for the next round), and multi-device rotation (faster turnaround means less waiting).

Additionally, the EcoFlow supports USB-C charging, letting you top up with a laptop charger—a practical feature for travel.

3. Ports & Connectivity

Winner: Tie (use-case dependent)

Jackery advantages:

• Dual USB-C 100W fast charging—better for simultaneously powering multiple laptops/tablets
• USB-C port can directly power high-draw devices like MacBook Pro

EcoFlow advantages:

• Dual AC outlets—plug in two appliances simultaneously
• X-Boost mode drives up to 600W devices (at reduced voltage)
• EPS feature (30ms switchover) ideal for sensitive backup devices like routers

4. Battery Life & Durability

Winner: EcoFlow River 2

Both use LiFePO4 (lithium iron phosphate) batteries—safer and longer-lasting than traditional NMC cells. But cycle life differs significantly:

• Jackery: After daily use, capacity drops below 80% in approximately 4 years
• EcoFlow: After daily use, capacity drops below 80% in approximately 8 years

While Jackery's warranty is "3+2 years" (5 years total), daily charge/discharge means you may need replacement after 4 years. EcoFlow's 3000-cycle rating means it outlasts the warranty period even with heavy daily use.

Temperature tolerance: Jackery supports -10°C to 45°C operation with high-temp protection at 60°C. EcoFlow supports -10°C to 45°C for charge/discharge.

5. Portability & Real-World Use

Winner: Tie

Both are close in weight and similarly sized—they fit easily into a backpack or car trunk.

Jackery's silence advantage: Jackery explicitly rates Silent Mode at ≤45dB, making it ideal for sleeping in a tent, quiet library or café backup, or hospital room use. EcoFlow has silent design features but doesn't publish specific decibel ratings.

The Verdict: Which Should You Buy?

Choose EcoFlow River 2 if:

• You need the fastest charging speed (60 minutes vs 120 minutes)
• You frequently make last-minute trip decisions and need quick top-ups
• You need EPS backup power (protects routers/desktops)
• You plan long-term high-frequency use (3000 cycle life)
• You need dual AC outlets for two devices simultaneously
• You want X-Boost mode for occasionally driving larger appliances

FAQ

Q1: Can these power stations run a CPAP machine overnight?

A: Yes, both can run most CPAP machines (without heated humidifier) for one full night. The Jackery 300 Plus (288Wh) provides approximately 5-8 hours of runtime at 30-60W draw, while the EcoFlow River 2 (256Wh) provides approximately 4-7 hours. If you use a CPAP with heated humidification (60-120W), neither will last a full night—consider the EcoFlow DELTA 2 (1024Wh) instead.

Q2: Which power station charges fastest with solar panels?

A: The EcoFlow River 2 charges faster with solar. With a 110W portable solar panel, the River 2 reaches full charge in approximately 2.5 hours, while the Jackery 300 Plus takes about 4 hours with a 100W panel. Both support MPPT for optimal solar conversion efficiency (~99%).

Q3: Can I use these power stations indoors during a power outage?

A: Yes, both are designed for safe indoor use. They produce zero emissions (no carbon monoxide like gas generators), are virtually silent, and can power essential devices like phones, laptops, routers, lights, and small appliances. The EcoFlow River 2's EPS (Emergency Power Supply) feature automatically switches to battery power within 30ms when grid power fails—ideal for keeping your internet router running without interruption.
