A Note on the Jackery 300-Series Lineup
Jackery has released two newer 300-class stations — the Explorer 300 v2 (dual 100W USB-C, ≤10ms UPS, 1-hour AC charge) and the ultra-compact Explorer 300D (5.5 lbs, integrated 140W USB-C carry strap). Both use the same reliable LiFePO₄ chemistry as the 300 Plus reviewed below, with meaningful upgrades to charging speed and UPS protection.
As of this update, neither the 300 v2 nor the 300D is reliably stocked on Amazon — they're currently easier to find through other retailers. Since we only link to Amazon, this review covers the Explorer 300 Plus, which remains in stock and is still a solid, well-built option in this capacity class. We'll update this page with a direct link as soon as the newer models are available through Amazon.
What Is the Jackery Explorer 300 Plus?
The Explorer 300 Plus is Jackery's entry-level LiFePO₄ power station. It delivers 288Wh of capacity and 300W continuous output (600W surge) in a compact 7.5 lb package. It's designed for first-time buyers, car campers, and anyone who wants a simple, reliable power source without unnecessary complexity.
The biggest upgrade from the original Explorer 300 is the battery chemistry — LiFePO₄ offers 3,000+ cycles (8-10 years of use) compared to the original's 500-cycle NMC battery. Jackery also improved the display and added a USB-C port. The core issue: at this price, faster and more capable alternatives now exist from EcoFlow and Anker.
What We Love
- Exceptional build quality — Jackery's legendary durability
- Ultra-quiet — no fan below 150W load
- 3,000+ cycle LiFePO₄ battery (10-year lifespan)
- Lightweight at 7.5 lbs — one of the lightest in class
- Cold weather operation down to -4°F
- Simple, no-app-required operation
- Excellent customer support reputation
The Trade-offs
- Only 300W output — lowest in class
- 2-hour charge vs 58–70 min for competitors
- Only one USB-C port, no pass-through charging
- No app connectivity or smart features
- Most expensive per watt-hour in this class
The one scenario where it wins
Cold weather. The Explorer 300 Plus operates down to -4°F (-20°C) — a genuine advantage for winter camping. If that's your use case, it's worth the price. For everyone else, the EcoFlow River 3 charges faster, outputs more, and costs less.

What's in the Box
Explorer 300 Plus unit, AC charging cable, car charging cable, DC8020 to solar adapter, documentation, and 2-year warranty card.
Output Testing
The 300W inverter handles phones, tablets, laptops, lights, CPAP machines, and small televisions. We ran a 100W CPAP machine for over 16 hours, a 65W laptop for 4-5 charges, and a 40W TV for 7+ hours. The 600W surge started a small mini-fridge but struggled with larger appliances — anything with a compressor over 400W is borderline.
Run Time Estimates
iPhone charging: 25+ charges · Laptop (65W): 4-5 charges · CPAP (40W): 16–18 hours · Mini-fridge (80W): ~3 hours · LED lights (10W): 28+ hours.
Charging Performance — The Weak Point
The 150W AC adapter delivers a full charge in about 2 hours. That's 3× slower than the Anker C300 (58 min) and 2× slower than the EcoFlow River 3 (70 min). For overnight charging, it's irrelevant. For a midday top-off during a power outage, the difference is real.
Cold Weather — The Standout Feature
The Explorer 300 Plus operates down to -4°F (-20°C) for discharge. In cold weather testing, it continued functioning without issue at temperatures that caused the EcoFlow River 3 to block solar charging. For winter camping, this is a genuine differentiator. See our cold weather guide → for full brand comparisons.
Noise Level
Essentially silent below 150W. The fan only engages above 200W, and even then it's barely noticeable at 32dB — quieter than a refrigerator. Excellent for bedside CPAP use.
Who Should Buy This
The Explorer 300 Plus earns its rating in one specific scenario: winter camping and cold-weather use where you need a portable station that keeps working below freezing. It's also a good fit for CPAP users who need silent bedside backup, and first-time buyers who simply trust the Jackery brand and want something foolproof.
Who Should Look Elsewhere
For three-season use, the EcoFlow River 3 charges in 70 minutes, outputs more, and costs less. The Anker SOLIX C300 adds pass-through charging and sub-10ms UPS at a similar price. If you're not camping in winter or specifically committed to the Jackery brand, you're paying a premium for build quality that newer competitors have matched.
The Verdict
Good hardware, real durability, genuine cold-weather advantage. But at this price, the competition has closed the gap on everything except brand trust and below-freezing operation. Buy it if you camp in winter or just want the simplest possible experience. Otherwise, look at the River 3 first.
