Side-by-Side Specs

The headline stats:

• EcoFlow charges in half the time (60 vs. 120 min)
• EcoFlow supports UPS pass-through for always-on router/device backup
• EcoFlow’s USB-C is double the speed (60W vs. 30W)
• Jackery has 12.5% more capacity (288 vs. 256Wh — about 32Wh more)
• Jackery is 0.2 lbs lighter (negligible)
• Jackery costs $20–$50 more for the additional capacity

Real-World Runtime: The 32Wh Difference in Perspective

The Jackery Explorer 300 Plus has 288Wh capacity vs. the River 2’s 256Wh. Applying 87% LiFePO4 efficiency:

• River 2 usable: 256Wh × 0.87 = 223Wh
• Jackery 300 Plus usable: 288Wh × 0.87 = 251Wh
• Difference: 28Wh — about 11% more usable energy in the Jackery

What 28Wh means in practice:

The honest assessment: The Jackery’s 28Wh advantage translates to 24–90 extra minutes depending on load. For CPAP use specifically, this margin is meaningful — if your CPAP session runs 5.5 hours, the River 2 won’t quite make it; the Jackery will.

For most other uses, the difference is nice-to-have, not essential.

The Recharge Speed Gap: Where EcoFlow Makes Its Case

This is the clearest differentiator between these two units.

EcoFlow River 2 — 60 minutes to full charge.
Jackery Explorer 300 Plus — 120 minutes to full charge.

That’s a 60-minute difference every time you recharge. Here’s what that means across different usage patterns:

Scenario 1: Weekend camping trip You arrive at camp Friday evening. The River 2 is fully charged in 1 hour after plugging in during the drive (if you have an inverter in your car). The Jackery takes 2 hours. For weekend warriors, 1 extra hour of charging time per trip is a genuine inconvenience.

Scenario 2: Rolling power outage Power returns for 90 minutes, then goes out again. River 2 recharges to 100%. Jackery 300 Plus recharges to 75%. This compounds over a day of rolling outages.

Scenario 3: Overnight charging at home Both are plugged in at 10 PM. River 2 is at 100% by 11 PM. Jackery is at 100% by midnight. For overnight charging: no meaningful difference.

Recharge speed matters most for: camping, rolling outages, and anyone who forgets to charge until they actually need it (which is most people).

UPS Pass-Through: The Feature That Changes Everything for Home Office Users

This is a feature the Jackery Explorer 300 Plus simply doesn’t have — and for a specific buyer, it makes the River 2 the only rational choice.

UPS (Uninterruptible Power Supply) mode means the River 2 stays permanently plugged into your wall outlet, with your router and devices plugged into the River 2. When grid power fails, switchover is instant — approximately 30 milliseconds — so your router never restarts, your laptop never loses power, and your smart home devices never reset.

Why this matters for remote workers and home office users:

During a power outage, your internet router typically reboots in 60–90 seconds. You lose your video call. Your work-in-progress auto-saves, maybe. Your VPN disconnects. Your smart security cameras go offline.

With the River 2 as a UPS: none of that happens. The router never knows the power went out. You continue your meeting. The cameras stay online.

The setup is simple: Plug the River 2 into the wall. Plug your router, desk lamp, and phone charger into the River 2. Set the app’s charge limit to 80%. Done. The River 2 silently maintains 80% charge indefinitely, waiting for the grid to fail.

The Jackery 300 Plus cannot do this. Its charging circuit is not designed for continuous pass-through operation.

USB-C Charging Speed: The Modern Device Consideration

River 2: 60W USB-C output Jackery 300 Plus: 30W USB-C output

Modern laptops (MacBook Air, Dell XPS 13, Surface Pro) charge at 30–65W via USB-C. The River 2’s 60W output charges most USB-C laptops at full rated speed. The Jackery’s 30W output charges them at half speed — the laptop charges, but slowly.

For users who rely on USB-C laptop charging without the AC outlet:

• River 2: full-speed charging for most laptops
• Jackery 300 Plus: slower charging — functional but not ideal

Solar Recharging: River 2’s Edge

The River 2 accepts up to 110W solar vs. the Jackery’s 80W — a 37% higher solar ceiling. With a 100W foldable panel, the River 2 charges approximately 1 hour faster. For camping with solar, this gap matters.

📱 EcoFlow App-Only Features: What the River 2 Can Do That the Jackery 300 Plus Cannot

This section covers a category of River 2 advantages that appear nowhere in the spec sheet — features exclusively available through the EcoFlow app that genuinely change how useful the unit is, particularly for budget buyers who want to maximize every watt-hour.

Feature 1: Quiet Charging Mode (X-Stream Throttling)

The EcoFlow app allows you to toggle between Standard Charging (fast, slightly louder fan) and Quiet Charging Mode (slower charge, minimal fan engagement).

Why this matters for campers and small-space users:

In a tent, a cabin, or a small bedroom, even a 25–30 dB fan hum is perceptible. When you’re charging the River 2 overnight in your sleeping area — a common camping scenario — Quiet Mode reduces the charge rate from ~300W to ~100W but keeps fan activity near-zero, producing virtually no audible sound.

The Jackery 300 Plus has no equivalent setting. Its charging speed is fixed at whatever rate the AC adapter delivers. No app control, no quiet option.

Camping scenario where this matters: You’re in your tent at 10 PM, the River 2 is at 30% after a long day, and you’ve found a campsite outlet. Plug in, enable Quiet Mode, and the unit recharges silently while you sleep — waking up to a near-full battery with no noise disruption.

Feature 2: EPS (Emergency Power Supply) Mode Toggle

EcoFlow’s EPS mode — the UPS pass-through feature — can be toggled on and off in the app. This matters because EPS mode generates slightly more heat in the River 2’s electronics (the inverter stays partially active to enable fast switchover). For users who want UPS functionality sometimes but not always, being able to toggle it is a meaningful convenience.

The Jackery 300 Plus has no EPS mode, period — this comparison is moot for Jackery users.

Feature 3: Discharge Protection Floor

The EcoFlow app allows you to set a minimum discharge percentage (10–30% in 10% increments). If you set the floor at 20%, the River 2 will never discharge its battery below 20% state of charge — preventing the deep discharge events that accelerate battery degradation.

Over time, this setting adds meaningful cycle life. An NMC unit that regularly depletes to 0% loses capacity significantly faster than one maintained above 20%. For a LiFePO4 unit like the River 2, the improvement is smaller but still real — approximately 10–15% more cycles from consistent use of the 20% floor.

The Jackery 300 Plus does not offer a configurable discharge floor. The BMS protects against dangerous deep discharge, but there’s no user-defined protection level.

Feature 4: Real-Time Wattage Monitoring (Both Input and Output)

The EcoFlow app displays precise wattage numbers for all active inputs and outputs — not just a battery percentage. You can see: “Solar: 87W incoming, AC output: 115W outgoing, Net: -28W, Estimated runtime: 8.4 hours.”

This real-time data lets you actively manage your power budget — unplug the laptop (saves 65W), and watch the runtime estimate jump from 8 hours to 14 hours in real-time.

The Jackery app (on the 300 Plus) shows battery percentage and a charge/discharge indicator, but not precise wattage in/out. The information density is lower.

App Feature Summary

The app verdict at the budget tier: The EcoFlow River 2’s app adds genuine, practical functionality — not just aesthetics. Quiet Charging Mode alone justifies the app for any camper or small-space user. The Jackery 300 Plus app is more limited at this tier.

The Lab’s Verdict: EcoFlow River 2 for Most Buyers

The EcoFlow River 2 wins this comparison for the majority of buyers because of three factors that are either decisive or significantly better:

1. UPS pass-through — a feature the Jackery simply doesn’t offer
2. 60-minute recharge — genuinely twice as fast
3. Lower price — often $40–$70 cheaper for equivalent use cases

The Jackery Explorer 300 Plus earns the recommendation in one specific scenario: if you need maximum capacity for extended CPAP camping without solar recharging, the extra 32Wh (28Wh usable) is worth the price premium and the slower recharge.
