EcoFlow RIVER 2 vs Jackery Explorer 300: Which $300 Power Station Actually Survives Winter Camping?

TESTED Updated November 2025

Struggling to keep your gadgets alive on a freezing winter campout? The secret isn’t just capacity—it’s about which battery can actually handle the cold. We took the two most popular sub-$300 power stations into Michigan’s sub-20°F wilderness to find the real winner for winter camping.

Two models dominate this space: the EcoFlow RIVER 2 (256Wh) and the Jackery Explorer 300 (293Wh). Both weigh under 8 pounds, both use reliable battery chemistry, and both frequently drop below $200 during sales—creating a real dilemma for first-time buyers.

After extensive field testing during Michigan’s brutal winter camping season—including sub-20°F overnight temperatures, multi-day trips in Manistee National Forest, and real-world device charging scenarios—we’ve identified the critical performance differences that matter when your gear needs to work in harsh conditions.

This comprehensive comparison reveals which compact power station delivers superior value for winter camping, car camping, emergency backup, and everyday portable power needs in 2025. For a broader comparison of these two brands across their full lineups, see our Jackery vs EcoFlow complete guide.

The 5 Critical Differences That Actually Matter

1. Battery Chemistry: LiFePO₄ vs Lithium-Ion

This is the most significant technical difference between these two units, with major implications for longevity and cold-weather performance.

EcoFlow RIVER 2: Uses LiFePO₄ (Lithium Iron Phosphate) battery cells rated for 3,000+ cycles to 80% capacity—approximately 10 years of regular use before significant degradation. LiFePO₄ chemistry also performs better in cold temperatures and has superior thermal stability.

Jackery Explorer 300: Uses traditional lithium-ion NMC (Nickel Manganese Cobalt) chemistry rated for approximately 500 cycles to 80% capacity. While this sounds dramatically worse, it still translates to 3-5 years of regular camping use—adequate for most recreational users.

Real-World Impact: During our winter testing at 15-25°F in Manistee National Forest, the EcoFlow RIVER 2 maintained approximately 90% of its rated capacity, while the Jackery Explorer 300 showed closer to 75-80% capacity in the same conditions. For winter camping specifically, this difference matters.

Technical Note: All lithium batteries have optimal temperature ranges—typically 32°F to 104°F for charging and -4°F to 140°F for discharging according to battery manufacturers. LiFePO₄ chemistry handles the lower end of these ranges better than NMC, which is why the EcoFlow maintains more capacity in cold conditions.

If you camp year-round in cold climates or plan to use this unit daily for years, EcoFlow’s LiFePO₄ advantage is substantial. For occasional three-season camping, Jackery’s NMC chemistry remains perfectly adequate.

2. Charging Speed: The EcoFlow Advantage

EcoFlow’s X-Stream charging technology delivers a decisive advantage for users who need rapid turnaround between adventures.

EcoFlow RIVER 2 AC Charging: Fully recharges from 0-100% in just 1 hour using a standard wall outlet—no special charger required. This is genuinely game-changing for day-trippers who return home, recharge during dinner, and head out again the next morning.

Jackery Explorer 300 AC Charging: Approximately 2 hours to full charge using the included 102W GaN fast charger through the AC outlet. While twice as long as EcoFlow, this remains competitive and the included fast charger adds significant value to the bundle.

Solar Charging Winner: EcoFlow

The RIVER 2 accepts up to 110W solar input and can fully charge in 2.3 hours under ideal conditions. The Jackery Explorer 300 maxes out at 65W solar input, requiring 5.5 hours for a full solar charge with a 100W panel (limited by the 65W input cap).

For users who rely heavily on solar charging during extended camping trips, EcoFlow’s superior solar input nearly cuts charge time in half—a significant advantage when daylight hours are limited.

3. Capacity and Runtime: Jackery’s Edge

While the difference isn’t massive, Jackery’s 14% larger capacity translates to meaningful extra runtime for multi-device charging scenarios.

EcoFlow RIVER 2: 256Wh capacity

Jackery Explorer 300: 293Wh capacity

That 37Wh difference equals approximately 3-4 additional smartphone charges or an extra hour of laptop runtime—meaningful when you’re rationing power on a winter camping trip without solar access.

However, EcoFlow’s X-Boost technology allows the RIVER 2 to power devices up to 600W by intelligently managing voltage—useful for running higher-draw appliances like small electric kettles or hair dryers that would otherwise be incompatible with a 300W output limit.

Expert Note on X-Boost: X-Boost is a voltage-regulation feature designed for resistive loads like kettles, hair dryers, and space heaters. It may not work reliably with sensitive electronics or motor-driven devices (like blenders or power tools), where the pure 300W sine wave output is always recommended. Always check device compatibility before relying on X-Boost for critical equipment.

4. App Control and Smart Features

The EcoFlow app provides monitoring and control features that Jackery’s Explorer 300 simply doesn’t offer.

EcoFlow RIVER 2 App Features:

• Real-time battery percentage and estimated runtime
• AC/DC output on/off control
• X-Boost mode toggle
• Charging speed adjustment (Standard/Fast)
• Firmware updates
• Device power consumption monitoring

Jackery Explorer 300: No app control. All monitoring happens via the on-unit LCD display, which shows battery percentage and input/output wattage.

Real-World Impact: The app proves useful for monitoring power consumption from inside your tent without unzipping in cold weather, and for toggling X-Boost mode when you need to run higher-wattage devices. That said, Jackery’s straightforward approach appeals to users who prefer simplicity over connectivity.

5. Value and Included Accessories

The bundle contents significantly affect overall value, especially for the Jackery Explorer 300.

EcoFlow RIVER 2 Includes: Power station, AC charging cable, car charging cable, user manual, 5-year warranty.

Jackery Explorer 300 Bundle Includes: Power station, AC adapter, car charger cable, 102W GaN fast charger with 2x 100W USB-C ports and 1x 18W USB-A port, user manual, 2-year warranty.

That 102W GaN fast charger is a genuine value-add—it’s ultra-compact (2.44″ x 2.27″ x 1.30″) and can charge USB-C laptops, tablets, and phones directly, serving double duty beyond just recharging the power station. Purchased separately, similar GaN chargers cost $40-60.

EcoFlow counters with a significantly longer 5-year warranty versus Jackery’s 2-year coverage—important peace of mind, especially given the LiFePO₄ battery’s 10-year lifespan potential.

Real-World Runtime: What These Power Stations Actually Run

We tested both units during winter camping trips in Northern Michigan to document actual runtime for common camping and emergency scenarios.

Testing Notes: All runtimes measured during actual winter camping trips in Northern Michigan at temperatures between 15-35°F. Cold temperatures reduce effective capacity—expect 10-20% better runtime in moderate conditions. EcoFlow’s LiFePO₄ chemistry showed less cold-weather degradation than Jackery’s NMC cells.

Winter Camping Performance: Cold Weather Testing

Since the headline promises insight on “which actually survives winter camping,” here’s what we found during extended cold-weather testing in Michigan’s Upper Peninsula and Manistee National Forest.

Cold Temperature Capacity Retention

Winter Camping Best Practices:

• Keep power stations inside your tent or vehicle overnight—not outside exposed to extreme cold
• Store in your sleeping bag during the coldest hours to maintain battery temperature
• Charge during the warmest part of the day (both units have cold-charging protection that may prevent charging below 32°F)
• The EcoFlow RIVER 2’s LiFePO₄ chemistry handles temperature swings better and charges in colder conditions

Verdict: For dedicated winter camping, the EcoFlow RIVER 2’s LiFePO₄ battery delivers meaningfully better cold-weather performance. If you primarily camp in three-season conditions (spring through fall), both units perform comparably.
