I love that this is a complete solar-ready kit right out of the box. The 256Wh LiFePO4 battery is a huge upgrade for long-term durability, and the 100W USB-C port is perfect for fast-charging my laptop. It’s ideal for a traveler who wants to be truly off-grid without buying extra gear. My main gripe is that it’s slightly heavier than the Explorer 300, and the battery capacity is a bit lower.
✅ Pros
- Includes a 40W solar panel for immediate off-grid use
- Long-life LiFePO4 battery with over 3,000 charge cycles
- Powerful 100W USB-C port for fast device charging
- Built-in app control and LED light add convenience
❌ Cons
- Lower 256Wh capacity than the Explorer 300
- Heavier at 7.9 pounds
- Lacks a dedicated DC car port

- POWER YOUR EXPECTATIONS: Featuring 2* AC outlet, 1* PD 60W USB-C port...
This is the classic workhorse with a proven track record. The 293Wh capacity gives you more juice per charge, and at 7.1 pounds, it’s the lightest option here. I found it perfect for weekend car camping where I can recharge from my vehicle. It’s best for someone who prioritizes maximum capacity and lightness, and doesn’t mind buying a solar panel separately. The older lithium-ion battery and slower 60W USB-C are noticeable downsides.
✅ Pros
- Higher 293Wh capacity for longer runtime
- Lightest unit at just 7.1 pounds
- Includes a DC car port for easy vehicle charging
- More USB-A ports for charging multiple small devices
❌ Cons
- Solar panel is not included
- Older lithium-ion battery chemistry
- Slower 60W USB-C output
Which One Should You Buy?
After testing both, I can’t give a single “best” answer. The right pick depends entirely on your specific travel style and how you plan to recharge.
Jackery Solar Generator 240 v2 is right for you if…
- You want a complete solar kit ready to go the moment you unbox it.
- You value the long-term durability of the LiFePO4 battery for years of trips.
- You need the 100W USB-C port to fast-charge a modern laptop or tablet.
Jackery Explorer 300 is right for you if…
- Your top priority is the highest capacity (293Wh) for the longest runtime.
- You’ll mostly recharge from a car outlet or wall plug, not solar.
- Every ounce counts, and you need the lightest option at 7.1 pounds.
❌ Who Should Skip All of These?
If you need to power a mini-fridge, electric cooler, or any appliance with a heating element, you’ll need a much more powerful station. Both of these max out at 300W AC.
For most lightweight travelers, I recommend the Solar Generator 240 v2 bundle. Having that solar panel included is a big improvement for staying powered off-grid.
Frequently Asked Questions
Which one charges faster, the 240 v2 or the Explorer 300?
The Jackery Solar Generator 240 v2 charges faster, especially from a wall outlet. It can fully recharge in about 2 hours. The Explorer 300 takes 2 hours to reach just 80% from a wall outlet. For solar, the 240 v2’s included 40W panel gives it a clear advantage.
Is the 240 v2’s LiFePO4 battery worth it over the Explorer 300’s?
Yes, if you plan to use the station for many years. The 240 v2’s LiFePO4 battery is rated for over 3,000 charge cycles, which is far more durable than the Explorer 300’s standard lithium-ion. It’s a better long-term investment for frequent travelers.
Which Jackery is better for backpacking and hiking?
The Explorer 300 is better for backpacking. It weighs 7.1 pounds compared to the 240 v2’s 7.9 pounds, and that difference matters on the trail. You get more capacity (293Wh) in a slightly lighter package, though you’ll need to pack a separate solar panel.
Can I charge a laptop with both of these power stations?
Yes, but the 240 v2 does it better. Its 100W USB-C port can fast-charge most modern laptops directly. The Explorer 300’s USB-C port is only 60W, which may be slow or insufficient for some power-hungry laptops, forcing you to use the AC outlet.
Is the included solar panel on the 240 v2 bundle actually useful?
Absolutely. The 40W panel is perfect for topping up the battery during a day hike or at a campsite. Without it, the Explorer 300 is just a battery box—you’d need to buy a separate solar panel, which adds significant cost and bulk to your kit.
Which one has more charging ports for phones and gadgets?
The Explorer 300 wins on port variety. It has two USB-A ports and a DC car port, which the 240 v2 lacks. The 240 v2 focuses on a more powerful 100W USB-C port. Choose the Explorer 300 if you need to charge several small devices at once.
My Final Verdict
My clear winner for lightweight travel is the Jackery Solar Generator 240 v2. It’s the smarter, more modern kit because it includes a 40W solar panel and has the superior, long-lasting LiFePO4 battery. The Explorer 300 is the runner-up, and it’s best for you if your top priority is the absolute highest capacity (293Wh) and you know you’ll only recharge from a car or wall outlet.
If you’re on the fence, ask yourself one question: do you want to be truly off-grid? If yes, the 240 v2’s included solar panel clinches it. If you’ll always have vehicle access, the Explorer 300’s extra capacity is appealing.
