Maria Santos doesn’t do “roughing it.” She does “glorified outdoor office.” Her setup at Joshua Tree last November looked like a tech reviewer’s fever dream: 16-inch MacBook Pro, two Sony cameras, a drone, an iPad for monitoring, and her phone running a hotspot for client calls.
All of it running off a single orange box the size of a lunchbox.
“I used to carry a 30-pound unit,” she told me over coffee after the trip. “Then I realized I was hauling 20 pounds of capacity I never used. The 300 does everything I need, and my back thanks me.”
The Jackery Explorer 300 is the company’s attempt to modernize their entry-level lineup. It’s got USB-C. It’s got more capacity. It’s got more output. But it also costs $100 more than the Explorer 240. Is that upgrade worth it?
If you’re Maria Santos, absolutely. If you’re just charging phones? Maybe not.

What We Liked
USB-C Power Delivery. This is the headline feature, and it matters. You can plug a USB-C laptop directly into the unit without carrying a separate wall charger. One cable. That’s it. Maria’s 16-inch MacBook Pro charged at 60W, which isn’t max speed but is plenty for keeping up with work.
More power where it counts. The 300W continuous output (up from 200W on the 240) doesn’t sound like a huge jump, but it opens up devices the 240 couldn’t handle. Certain camera charging stations, small projectors, and older laptops that don’t support USB-C charging all work now.
The same portability. At 7.1 pounds, this is only half a pound heavier than the Explorer 240. Jackery managed to add 22% more capacity without a meaningful weight penalty. That’s good engineering.
Fast enough charging. 4.5 hours to full is 30 minutes faster than the 240. Not revolutionary, but when you’re trying to top off before heading out the next morning, every minute helps.
Pass-through charging. You can charge the unit while it’s powering devices. Plug it into AC at the campground bathroom and charge your laptop at the same time. Not all power stations do this safely.
What Could Be Better
The USB-C wattage. 60W is fine for most laptops, but it won’t fast-charge a 16-inch MacBook Pro at full speed (those need 96-140W). If you’re doing heavy video editing, your battery might still drain slowly even while plugged in.
Still NMC batteries. Like the 240, this uses older Li-ion NMC chemistry with 500-800 cycle life. The newer Jackery v2 models use LiFePO4 with 4,000+ cycles. This is the older tech at a premium price.
The pricing problem. Here’s the uncomfortable truth: on sale, you can sometimes get the Jackery Explorer 1000 v2 for $499. That’s 3.6x the capacity, 5x the output, LiFePO4 batteries, and two USB-C ports at 100W each. The Explorer 300 at $299 is… harder to justify when you do the math.
Limited solar input. 100W max means 5-7 hours to charge with a properly sized panel. In real-world conditions with shade, clouds, and imperfect panel angles, expect 8-10 hours.
Runtime Estimates
| Device | Runtime |
|---|---|
| Smartphone (15W) | ~17 charges |
| Tablet (30W) | ~7 charges |
| Laptop via USB-C (50W) | ~5 hours |
| Laptop via AC (65W) | ~4 hours |
| LED Lights (10W) | ~25 hours |
| Small Fan (40W) | ~6 hours |
| 32” TV (50W) | ~5 hours |
| Drone batteries (varies) | ~6-8 full charges |
Real-world estimates. Actual runtime varies by device efficiency and inverter losses.
Who Should Buy This
USB-C laptop users who travel light. If your daily driver charges via USB-C and you want the simplest possible setup—one cable from power station to laptop—this is your jam.
Content creators on location. Photographers and videographers who need to charge cameras, drones, laptops, and phones without hauling a 40-pound unit.
Weekend warriors who want modern convenience. The USB-C port means fewer cables to pack. One USB-C to USB-C cable can charge your phone, tablet, and laptop (sequentially).
People who hike to camp. At 7.1 pounds, this is still carry-on-light. You won’t dread packing it.
Who Should Look Elsewhere
Appliance users. Still no fridge, microwave, or coffee maker at 300W. You need 1,000W+ for those.
Value seekers. The Explorer 300 sits in an awkward spot. The 240 is cheaper if you don’t need USB-C. The 1000 v2 is barely more expensive on sale and gives you way more capability.
Daily power users. The NMC battery chemistry won’t last as long under heavy use.
Windows gaming laptop owners. Those power bricks often draw 150-250W. The 300W output gives you zero headroom.
The Verdict
The Jackery Explorer 300 is a good power station trapped in a weird market position.
On its own merits, it’s excellent. USB-C Power Delivery, 293Wh capacity, still portable enough to carry without complaint. Maria Santos swears by hers—she’s used it on location shoots from Oregon to Florida without a single issue.
The problem is value. For $100 more (sometimes $200 more on sale), you can get 1,000Wh+ units with LiFePO4 batteries, double the output, and faster charging. The Explorer 300 made sense at launch. In 2026, it’s harder to recommend unless you specifically need the lightest possible unit with USB-C.
If you’re choosing between this and the Explorer 240: get the 300 if you have USB-C devices. Get the 240 if you don’t. Simple as that.
4 out of 5 stars. Loses a star for pricing in the current market. But if you need exactly what it offers, it delivers.
