Quick Verdict
The Jackery Explorer 300 Plus is exactly what we've been asking Jackery to make for years: a compact power station with modern features. It swaps the older NMC battery for LFP chemistry (3,000 cycles vs 500), adds USB-C Power Delivery, and charges from wall in just 2 hours.
At 7.8 lbs with 288Wh capacity, it's the perfect size for day trips, weekend camping, or keeping in your car for emergencies. The 300W AC output won't power a space heater, but it handles everything else you'd reasonably want in this size class: laptops, drones, CPAP machines, phones, cameras, and mini fridges.
Our recommendation: If you want a compact, grab-and-go power station that will last a decade, this is it. The Explorer 300 Plus represents Jackery catching up to (and in some ways surpassing) the competition. At $299, it's an easy recommendation.
🏆 Why We Love It
The Explorer 300 Plus fixes every complaint we had about the original 300: faster charging (2h vs 5h), longer battery life (3,000 vs 500 cycles), USB-C PD, and better efficiency. It's proof that Jackery is listening.

Real-World Testing
📱 Phone Charging
The Explorer 300 Plus charged an iPhone 15 Pro from 0-100% approximately 14 times before depleting. USB-C PD delivered fast charging speeds (0-50% in under 30 minutes). For a weekend camping trip, that's more than enough for a family of four.
💻 MacBook Air M2
Running a MacBook Air M2 at moderate brightness with light work, we got approximately 5 hours of runtime. The USB-C PD port can also charge the MacBook at full speed (67W) — no adapter needed.
🎮 Nintendo Switch
Charged a Nintendo Switch approximately 8 times. The USB-C port delivers power while playing, so you can game indefinitely (until the 300 Plus runs out, anyway).
💨 CPAP Machine
Running a ResMed AirSense 10 (without humidifier), we got approximately 5 nights of 8-hour sessions. With the humidifier on, that drops to about 2 nights. Good for short camping trips.
📷 Camera Batteries
Charged Sony NP-FZ100 batteries approximately 20+ times via USB-C. Perfect for photographers who need reliable power in the field.
💡 Pro Tip: USB-C Pass-Through
The 100W USB-C port works bidirectionally. You can charge the Explorer 300 Plus with a USB-C PD charger (if you forgot your wall adapter) or use it as a 100W output for laptops. Extremely versatile.
Charging Speed
One of the biggest upgrades over the original Explorer 300:
| Charging Method | Time to Full |
|---|---|
| Wall outlet (AC adapter) | 2 hours |
| USB-C PD (65W charger) | ~3.5 hours |
| 12V car charger | ~5 hours |
| 100W solar panel | ~4 hours (ideal conditions) |
| 40W solar panel | ~8 hours (ideal conditions) |
The 2-hour wall charging is a game-changer for spontaneous trips. Realize you're going camping tomorrow? Charge it overnight (or in a couple hours that evening) and you're ready.
Explorer 300 Plus vs Original 300
Wondering if the "Plus" upgrade is worth it? Here's the direct comparison:
| Feature | Explorer 300 | Explorer 300 Plus NEW |
|---|---|---|
| Capacity | 293Wh | 288Wh |
| Battery Type | NMC | LFP |
| Cycle Life | 500 cycles | 3,000 cycles |
| AC Charge Time | 5 hours | 2 hours |
| USB-C | ❌ | ✓ (100W PD) |
| Expandable | ❌ | ✓ |
| UPS Mode | ❌ | ✓ |
| App Control | ❌ | ✓ |
| Weight | 7.1 lbs | 7.8 lbs |
| Price | ~$280 | ~$299 |
The verdict: The Explorer 300 Plus is worth every penny of the ~$20 premium. You're getting 6× the battery lifespan, 2.5× faster charging, USB-C, and expandability. There's no reason to buy the original 300 in 2026.
How It Compares
| Feature | Jackery 300 Plus | EcoFlow River 2 | Anker 521 | Bluetti EB3A |
|---|---|---|---|---|
| Capacity | 288Wh | 256Wh | 256Wh | 268Wh |
| AC Output | 300W | 300W | 200W | 600W |
| Battery | LFP | LFP | LFP | LFP |
| Cycles | 3,000 | 3,000 | 3,000 | 2,500 |
| AC Charge | 2 hrs | 1 hr | 4 hrs | 1.5 hrs |
| USB-C PD | 100W | 60W | 60W | 100W |
| Expandable | ✓ | ❌ | ❌ | ❌ |
| Weight | 7.8 lbs | 7.7 lbs | 9.2 lbs | 10.1 lbs |
| Price | $299 | $249 | $199 | $229 |
Bottom line: The EcoFlow River 2 charges faster (1 hour vs 2) and costs $50 less, but the Jackery 300 Plus has more capacity (288 vs 256Wh), a higher USB-C wattage (100W vs 60W), and expandability. The Bluetti EB3A has the highest AC output (600W) but is heavier. Choose based on your priorities.
Who Should Buy This?
The Explorer 300 Plus is perfect if you:
- Want an ultralight, grab-and-go power station
- Primarily charge phones, tablets, laptops, and cameras
- Need USB-C Power Delivery (100W)
- Want a battery that will last 10+ years
- Might want to expand capacity later
- Value Jackery's brand reputation and support
Look elsewhere if you:
- Need to power high-draw appliances (get the Explorer 1000 Plus)

The Verdict
The Jackery Explorer 300 Plus is the compact power station we've been waiting for. It fixes every flaw of the original with an LFP battery, fast charging, USB-C PD, and expandability. At 7.8 lbs, it's perfect for camping, road trips, or emergency backup. Highly recommended.
