Quick Verdict
The Jackery Explorer 240 is a legacy product — the power station that introduced many people to portable power. At just 6.6 lbs with 240Wh capacity and a sub-$200 price, it remains an attractive entry point for budget-conscious buyers who need basic phone and laptop charging.
However, we need to be honest: The Explorer 240 uses older NMC battery chemistry (500 cycle lifespan vs 3,000 for LFP), charges slowly (5.5 hours), and lacks USB-C Power Delivery. For just $100 more, the Explorer 300 Plus offers dramatically better specs.
Our recommendation: Buy the Explorer 240 if you're on a strict budget, need an absolute minimum for occasional camping, or find it on deep sale (under $150). Otherwise, spend the extra $100 for the 300 Plus — you'll get a power station that lasts 6× longer and charges 2.5× faster.
⚠️ Consider the Upgrade
The Explorer 240 was designed before LFP batteries and USB-C PD became standard. For $100 more, the Explorer 300 Plus gives you 3,000 cycles (vs 500), 2-hour charging (vs 5.5h), and 100W USB-C. We strongly recommend it unless budget is a hard constraint.

Real-World Testing
📱 Phone Charging
The Explorer 240 charged an iPhone 15 Pro from 0-100% approximately 12 times before depleting. The USB-A ports top out at 12W total, so expect slower charging than USB-C PD devices. Still plenty for a weekend camping trip.
💻 MacBook Air
Running a MacBook Air M2 at moderate brightness, we got approximately 4 hours of runtime using the AC outlet. Note: you'll need to use a USB-C charger with the AC outlet — no direct USB-C port is available.
💨 CPAP Machine
Running a ResMed AirSense 10 (without humidifier), we got approximately 4 nights of 8-hour sessions. With the humidifier on, that drops to about 1.5 nights. Adequate for short trips, but consider the larger models for extended use.
📷 Camera Batteries
Charged Sony NP-FZ100 batteries approximately 15+ times via the DC port with a compatible charger. The 240 remains a solid choice for photographers on a budget.
💡 LED Lights
Powered a 10W LED lamp for approximately 20 hours. Perfect for keeping your campsite lit through multiple evenings.
💡 Best Use Case
The Explorer 240 shines for basic charging needs: phones, tablets, cameras, drones, and small electronics. It's not designed for high-draw appliances — keep expectations realistic and you'll be happy with it.
Charging Speed
This is where the Explorer 240 shows its age:
| Charging Method | Time to Full |
|---|---|
| Wall outlet (AC adapter) | 5.5 hours |
| 12V car charger | ~6.5 hours |
| 60W solar panel | ~5 hours (ideal conditions) |
| SolarSaga 100W panel | ~4 hours (ideal conditions) |
Compare this to the Explorer 300 Plus at 2 hours, and you see why we keep recommending the upgrade. If you're planning spontaneous trips, that 5.5-hour charge time means overnight charging is mandatory.
Explorer 240 vs Modern Alternatives
| Feature | Explorer 240 | Explorer 300 Plus BETTER | EcoFlow River 2 | Anker 521 |
|---|---|---|---|---|
| Capacity | 240Wh | 288Wh | 256Wh | 256Wh |
| AC Output | 200W | 300W | 300W | 200W |
| Battery | NMC OLD | LFP | LFP | LFP |
| Cycles | 500 | 3,000 | 3,000 | 3,000 |
| AC Charge | 5.5 hrs | 2 hrs | 1 hr | 4 hrs |
| USB-C PD | ❌ | 100W | 60W | 60W |
| Weight | 6.6 lbs | 7.8 lbs | 7.7 lbs | 9.2 lbs |
| Price | $199 | $299 | $249 | $199 |
Bottom line: The Explorer 240 is the lightest and cheapest, but it has the shortest lifespan (500 vs 3,000 cycles) and slowest charging. The Anker 521 matches its price while offering LFP battery and 6× the cycle life. If price is your primary concern, the Anker 521 is actually the smarter budget pick in 2026.
Who Should Buy This?
The Explorer 240 is a reasonable choice if you:
- Have a strict budget under $200
- Find it on deep sale (under $150)
- Only need basic phone/tablet charging
- Want the lightest possible option (6.6 lbs)
- Don't need USB-C Power Delivery
- Plan to use it infrequently (500 cycles is enough)
Get something else if you:
- Want a battery that lasts 10+ years → Explorer 300 Plus
- Need USB-C PD for modern devices → Explorer 300 Plus
- Want faster charging → EcoFlow River 2
- Need more AC output → Explorer 500
- Want the best budget LFP option → Anker 521
🔋 The LFP Reality Check
At 500 cycles, the Explorer 240 will retain 80% capacity after roughly 1-2 years of regular use. LFP models like the 300 Plus hit that same point after 6-10 years. If you're keeping this long-term, the 300 Plus is actually cheaper per year of use.
The Verdict
The Jackery Explorer 240 is a proven, reliable budget power station that introduced millions to portable power. It's still functional in 2026, but newer technology has left it behind. The NMC battery, slow charging, and lack of USB-C PD make it hard to recommend over modern alternatives like the Explorer 300 Plus or even the cheaper Anker 521. Buy only if on sale or budget is a hard constraint.
