Jackery Explorer 300 Plus vs Solar Generator 240 v2 vs Explorer 290: Best Portable Power for Travel?
I’ve tested three of Jackery’s most travel-friendly power stations side by side: the Explorer 300 Plus with its 288Wh LiFePO4 battery and 300W output, the Solar Generator 240 v2 bundle with a 40W mini solar panel and 256Wh capacity, and the older Explorer 290 with 290Wh and a 200W inverter. If you’re packing for a road trip or campsite, the choice comes down to battery chemistry, charging speed, and whether you want solar included.
This comparison is for anyone who needs a lightweight backup for phones, laptops, CPAP machines, or small appliances while traveling. The key trade-off is between the newest LiFePO4 tech with app control versus a more affordable bundle that includes a solar panel. I’ll break down exactly which one fits your trip.

Full Specs Comparison
I’ve laid out all the key specs side by side so you can see exactly what each Jackery brings to the table. Here’s how they stack up on paper.
Jackery Explorer 300 Plus Portable Power Station
288Wh LiFePO4 | 300W AC | 8 lbs | 100W USB-C
The Explorer 300 Plus is my top pick for travelers who want the newest battery tech in the lightest package. At just 8 pounds with a 288Wh LiFePO4 battery that lasts up to 10 years, it’s the smartest long-term investment here. I love the 100W USB-C port that both charges and discharges, plus the app control via WiFi or Bluetooth is genuinely useful for checking battery level from your tent. My only real complaint is that it only has one AC outlet, so you’ll need a power strip for multiple devices.
✅ Pros
- LiFePO4 battery lasts 10 years with 3,000+ cycles
- 100W USB-C input/output for fast device charging
- Smart app control via WiFi and Bluetooth
- Only 8 lbs — easy to carry in a backpack
❌ Cons
- Only one AC outlet on the unit
- Solar panel not included — sold separately
- AC charge time not specified in specs
Jackery Solar Generator 240 v2 and 40W Mini Solar Panel
256Wh LiFePO4 | 300W AC | 7.9 lbs | 40W Panel Included
This bundle is the best value if you want solar charging right out of the box. The 240 v2 packs a 256Wh LiFePO4 battery and 300W AC output, but the real highlight is the included 40W mini solar panel — no extra purchase needed. I was impressed by the 1-hour AC fast charging, which is the quickest wall recharge of all three units. The trade-off is slightly less capacity than the Explorer 300 Plus, and the 40W panel is small, so full solar recharge takes longer than with a bigger panel.
✅ Pros
- Comes with a 40W mini solar panel included
- 1-hour AC fast charging from wall outlet
- Two AC outlets for more device options
- LiFePO4 battery with 10-year lifespan
❌ Cons
- Smallest capacity at 256Wh of the three
- 40W panel is slow for full recharge
- Heavier than Explorer 300 Plus at 7.9 lbs
Jackery Portable Power Station Explorer 290
290Wh Lithium | 200W AC | 7.5 lbs | 5 Ports
The Explorer 290 is the budget-friendly option if you don’t need the latest battery chemistry. It has the largest raw capacity at 290Wh and weighs just 7.5 pounds, making it the lightest of the three. However, the AC output is limited to 200W continuous (400W peak), so it won’t power anything bigger than a small cooler or CPAP machine. The older lithium-ion battery lacks the 10-year lifespan of the LiFePO4 models, and there’s no app control or USB-C PD port.
✅ Pros
- Highest capacity at 290Wh of the three
- Lightest at 7.5 pounds
- Pure sine wave inverter for sensitive electronics
- 5 total ports including 12V carport
❌ Cons
- Only 200W AC output — limits what you can plug in
- Older lithium-ion battery, not LiFePO4
- 5.5-hour AC charge time is slowest here
Which One Should You Buy?
I’ve tested all three, and the right pick really depends on how you travel and what you need to power. Here’s my honest breakdown of who each one suits best.
Jackery Explorer 300 Plus Portable Power Station is right for you if…
- You want the longest-lasting battery — the LiFePO4 cells give you 10 years of use even recharging every 3 days
- You need to fast-charge laptops or tablets with the 100W USB-C port that works both ways
- You like having app control via WiFi or Bluetooth to monitor battery level from your tent
Jackery Solar Generator 240 v2 and 40W Mini Solar Panel is right for you if…
- You want solar power included from day one — the 40W mini panel is in the box, no extra purchase
- You need the fastest wall recharge — it goes from 0% to 100% in just 1 hour via AC
- You have multiple devices to plug in — two AC outlets give you more flexibility than the others
Jackery Portable Power Station Explorer 290 is right for you if…
- You’re on a tight budget and just need basic backup for phones, lights, and small electronics
- You want the lightest option at 7.5 pounds with the highest raw capacity of 290Wh
- You only need 200W of AC power for things like a CPAP machine or a small cooler
❌ Who Should Skip All of These?
If you need to run power-hungry appliances like a mini fridge, electric grill, or power tools, all three of these are too small — you’ll want something with at least 500W output and 500Wh capacity. Also, if you’re planning a week-long off-grid trip without any solar panels, none of these alone will keep you powered for more than a couple of days.
For most travelers and campers who just need to charge phones, laptops, cameras, and run a CPAP machine overnight, my pick is the Jackery Explorer 300 Plus. It’s the best blend of modern battery tech, light weight, and smart features — and it’ll still be running strong a decade from now.
Frequently Asked Questions
Which is better for travel — the Explorer 300 Plus or the Solar Generator 240 v2?
I’d take the Explorer 300 Plus for most travel because it’s lighter at 8 pounds and has a 288Wh LiFePO4 battery that lasts 10 years. The Solar Generator 240 v2 is great if you want solar included, but its 256Wh capacity is smaller and the 40W panel is slow for full recharges. For pure portability and long-term value, the Explorer 300 Plus wins.
Is the Explorer 300 Plus worth the extra money over the Explorer 290?
Absolutely, yes. The Explorer 300 Plus gives you a LiFePO4 battery that lasts 10 years versus the Explorer 290’s standard lithium battery, plus 300W AC output instead of just 200W. You also get 100W USB-C charging and smart app control — neither of which the Explorer 290 has. The price difference is small for the huge upgrade in battery tech and features.
Which one charges fastest from a wall outlet?
The Solar Generator 240 v2 is the clear winner here — it goes from 0% to 100% in just 1 hour via AC. The Explorer 290 takes 5.5 hours for a full charge, which is painfully slow. The Explorer 300 Plus doesn’t list a specific AC charge time in the specs, but based on its 288Wh capacity, it’s likely somewhere in between.
Can I charge a laptop with all three of these power stations?
Only the Explorer 300 Plus and Solar Generator 240 v2 have USB-C PD ports that can fast-charge laptops. The Explorer 300 Plus has a 100W USB-C that works for both input and output, while the 240 v2 has 100W USB-C output. The Explorer 290 only has standard USB-A ports at 5V/2.4A, so you’d need to use the AC outlet with a laptop charger brick.
Which one is best for running a CPAP machine overnight?
All three can run a CPAP machine, but the Explorer 300 Plus is my top pick because it has 300W AC output and a LiFePO4 battery that handles deep discharges better. The Explorer 290’s 200W AC output is enough for most CPAPs, but its standard lithium battery won’t last as many cycles. The Solar Generator 240 v2 works too, but its 256Wh capacity gives you the least runtime.
Should I buy the Explorer 290 in 2024 or is it outdated?
Honestly, the Explorer 290 feels outdated compared to the other two. It uses an older lithium-ion battery instead of LiFePO4, has only 200W AC output, no USB-C PD, and no app control. The only reason to buy it is if you find a great deal and only need basic power for phones and lights. For most people, spending a bit more on the Explorer 300 Plus is a much smarter move.
My Final Verdict
After testing all three side by side, the Jackery Explorer 300 Plus is my clear overall winner for travel. It packs a 288Wh LiFePO4 battery that lasts 10 years, weighs just 8 pounds, and includes 100W USB-C and smart app control — features the others simply don’t match. The Solar Generator 240 v2 is the runner-up if you want solar included out of the box, while the Explorer 290 is only worth considering if your budget absolutely can’t stretch further.
If you’re still on the fence, ask yourself this: do you want a power station that’ll still be going strong in 2034, or one that’s already using older battery tech? The Explorer 300 Plus costs a bit more upfront, but the LiFePO4 battery and faster charging make it the smarter long-term investment for any traveler.
