EcoFlow River 2 vs Jackery Explorer 300 Plus
Quick Answer
The EcoFlow River 2 wins for most apartment renters: it charges in 1 hour (vs 2+ hours for the 300 Plus), costs ~$249 (vs ~$299), and both now use LFP battery chemistry. The Jackery 300 Plus has slightly more capacity (288Wh vs 256Wh) and better solar panel ecosystem integration if you're already in the Jackery ecosystem. For pure outage backup in an apartment, the River 2's 1-hour charge time is a meaningful advantage — you can top it off during a weather warning in the time it takes to watch a show.

Battery Chemistry: LFP in Both
This used to be a meaningful differentiator — the original River 2 launched with LFP while many competing budget units used NMC. The Jackery Explorer 300 Plus also uses LFP, so they're equal on this front.
LFP matters for apartment use because it has a thermal runaway threshold of ~270°C vs ~170°C for NMC. Both stations are safe for indoor use, but LFP is genuinely more stable. Both carry 3,000+ cycle ratings at 80% capacity retention — either one will outlast most people's needs before meaningful degradation.
Charging Speed: River 2's Biggest Advantage
The River 2 charges from empty to full in 1 hour via AC wall outlet. The Jackery 300 Plus takes roughly 2 hours. This isn't a minor spec difference — it's a real-world use case difference.
When a storm warning comes through, you have a window to charge before the power might go out. With the River 2, you plug in for an hour and you're done. With the 300 Plus, you need to plan further ahead or accept a partial charge.
| Method | EcoFlow River 2 | Jackery 300 Plus |
|---|---|---|
| AC wall (0-100%) | ~1 hour ✅ | ~2 hours |
| Solar (100W panel) | ~3 hours | ~4-5 hours (max 80W input) |
| Car 12V port | ~10-12 hours | ~12-14 hours |
Output and What They Can Run
Both stations have identical AC output: 300W continuous, 600W surge. Both have 2 AC outlets. This means they run the same devices — and hit the same limits.
What both can run: router, laptop, phone charging, LED lights, CPAP (no humidifier), tablet, small fans.
What neither can run: refrigerator (needs 1,000W+ for startup surge), window AC, microwave, space heater, hair dryer.
| Device | River 2 (256Wh) | Jackery 300 Plus (288Wh) |
|---|---|---|
| WiFi router (12W) | ~18 hrs | ~20 hrs |
| Laptop (50W) | ~4.4 hrs | ~4.9 hrs |
| Phone charging (20W) | ~10.9 hrs (~12 full charges) | ~12.2 hrs (~14 charges) |
| CPAP no humidifier (35W) | ~6.2 hrs (~1 night) | ~7 hrs (~1 night) |
| All essentials (85W) | ~2.6 hrs | ~2.9 hrs |
The 32Wh capacity difference (288 vs 256Wh) gives the Jackery about 12% more runtime — half an hour on a laptop, one extra hour for a router, roughly one extra phone charge. Not nothing, but not a decisive factor given the $50 price difference.
The Jackery 300 Plus has a better USB-C port situation: two USB-C ports at up to 100W each vs the River 2's single 60W USB-C. If you're charging multiple USB-C devices simultaneously, this matters.
Solar Charging
The River 2 accepts up to 110W of solar input; the Jackery 300 Plus caps at 80W. For a balcony solar setup, the River 2 recharges faster and is compatible with more panel options. If you're already invested in Jackery's SolarSaga panel ecosystem and have their 100W panel, you'll be capped at the 300 Plus's 80W input limit anyway.
In practice, a 100W panel in good sun produces 70-90W of actual output. The River 2 can use all of it; the Jackery 300 Plus will throttle at 80W. Minor difference for most users, but it adds a bit to the River 2's daily solar yield.
The Verdict
| Category | Winner | Why |

| Price | River 2 | ~$50 less |
| Capacity | Jackery 300 Plus | 32Wh more (12%) |
| Charge speed | River 2 | 1 hr vs 2 hrs |
| Solar input | River 2 | 110W vs 80W max |
| USB-C ports | Jackery 300 Plus | Two 100W ports vs one 60W |
| Battery chemistry | Tie | Both LFP |
| Weight | River 2 | 7.7 lbs vs 8.4 lbs |
| Overall for apartments | River 2 | Better price, faster charge |
Buy the EcoFlow River 2 if: you want the lowest price, fastest charge time, and don't care about having two USB-C ports.
Buy the Jackery Explorer 300 Plus if: you're already in the Jackery ecosystem (have their solar panels), value the extra USB-C port for dual device charging, or want 12% more capacity and the $50 price difference doesn't matter.
Consider stepping up to the Bluetti AC70 (~$329) if: you need to run a CPAP for multiple nights, want to power a mini-fridge, or want meaningfully more runway during a longer outage. The AC70 has 3x the capacity of either budget unit for $30-80 more.
Frequently Asked Questions
Which is better, EcoFlow River 2 or Jackery Explorer 300 Plus?
For most buyers, the EcoFlow River 2 is the better choice. It's $50 cheaper, charges in 1 hour (vs 2 hours for the 300 Plus), and accepts more solar input (110W vs 80W). The Jackery 300 Plus has slightly more capacity (288Wh vs 256Wh) and two USB-C ports vs one. Both use LFP battery chemistry with 3,000+ cycle ratings.
Can the Jackery Explorer 300 Plus run a refrigerator?
No. A refrigerator surges to 400-1,500W on startup, which far exceeds the 300 Plus's 300W continuous and 600W surge rating. Even if the fridge started, 288Wh would be drained in under 2 hours. Neither the River 2 nor the Explorer 300 Plus can meaningfully run a refrigerator. For fridge backup, you need at least 768Wh and 1,000W+ output — like the Bluetti AC70 or EcoFlow Delta 2.
Does the Jackery Explorer 300 Plus use LFP batteries?
Yes. The Explorer 300 Plus uses LFP (LiFePO4) battery chemistry, giving it a 3,000+ cycle rating and a higher thermal runaway threshold (~270°C) compared to NMC lithium. This makes it safe for indoor apartment use. Earlier Jackery models used NMC chemistry, so make sure you're looking at the "Plus" version of the 300.
