Real-World Testing: Northern Michigan Backcountry Performance
3-Night Backcountry Test: Nordhouse Dunes Wilderness
Testing the Explorer 300 as Primary Backpacking Power
The real test for any “portable” power station: can you actually carry it into the backcountry? I hauled the Explorer 300 on a 3-night trip through Nordhouse Dunes Wilderness—one of Michigan’s most remote Lake Michigan shoreline areas with no services or vehicle access.
What I Powered Over 3 Days:
• iPhone 15 Pro: 6 full charges
• DJI Mini 4 Pro batteries: 4 charges
• Garmin inReach Mini 2: 2 charges
• Black Diamond headlamp: 2 charges
• Camera battery (Sony NP-FZ100): 3 charges
Results: Started Friday evening at 100%. Returned Sunday afternoon with 12% remaining—enough to document the hike out. The 7.1-pound weight disappeared inside my 65L pack, and I genuinely forgot it was there during the 4-mile hike to camp.
The Explorer 300 handled everything I needed for a long weekend without solar recharging. For week-long trips, pairing with the SolarSaga 100W panel would provide indefinite power.
💡 Pro Tip: Pack the Explorer 300 in the middle of your backpack close to your spine—the weight distribution feels more natural than external attachment. At 7.1 lbs, it adds less weight than carrying an extra 2 liters of water.
Photography Expedition: Pictured Rocks National Lakeshore
Full-Day Landscape Photography Power Solution
Pictured Rocks offers some of Michigan’s most dramatic scenery, but the remote locations mean no power access. I tested the Explorer 300 during a 9-hour photography day covering Miners Beach to Chapel Rock.
Photography Gear Powered:
• Sony A7IV battery charger (15W): Ran continuously
• iPhone charged twice during breaks
• Portable LED panel: 45 minutes during blue hour
• MacBook Air: Quick photo review and backup
Results: Used 41% capacity over the full 9-hour day. The 60W USB-C PD port was the standout feature—I could charge my MacBook Air from 20% to full while the Explorer 300 still showed 58% remaining. That bidirectional USB-C capability is rare in this size class.
The pure sine wave AC output ran the battery charger without any flickering or issues that modified sine wave inverters cause with sensitive electronics.
💡 Pro Tip: The Explorer 300’s LCD screen shows real-time input/output wattage—invaluable for photographers managing power budgets. I could see exactly how much each device drew and calculate remaining runtime on the fly.
Cold Weather Performance: Wilderness State Park
Overnight Freezing Temperature Test
Late fall camping at Wilderness State Park in Michigan’s Lower Peninsula gave me the chance to test cold weather performance. Overnight temps dropped to 28°F with the Explorer 300 stored in my tent vestibule (uninsulated).
Cold Weather Test Protocol:
• Charged to 100% before sunset
• Stored in tent vestibule overnight (28°F)
• Measured capacity at dawn before warming
• Tested output performance while cold
Results: Approximately 8% phantom drain overnight—acceptable for lithium-ion chemistry in freezing conditions. The unit powered my phone and headlamp without hesitation at 28°F. Charging efficiency would be reduced at this temperature, but output remained stable.
For serious winter camping, keep the Explorer 300 inside your sleeping bag or shelter to maintain battery efficiency. The compact size makes this practical in ways larger power stations can’t match.
💡 Pro Tip: In cold weather, bring the Explorer 300 into your tent or sleeping bag area before bed. Body heat and shelter warmth prevent the capacity loss that affects all lithium batteries below freezing. The 7.1 lb weight makes this feasible unlike larger units.
Solar Charging Test: Baldwin Campsite
Jackery Solar Generator Performance with SolarSaga 100W
The Explorer 300 transforms into a complete Jackery solar generator when paired with compatible panels. I tested the full setup during a clear October day at a dispersed campsite near Baldwin, MI.
Solar Test Conditions:
• Panel: Jackery SolarSaga 100W
• Weather: Clear skies, direct sun 10am-3pm
• Starting charge: 0% (completely depleted)
• Panel positioning: Adjusted twice for optimal angle
Results: 0% to 87% in 5 hours of good sunlight. The integrated MPPT (Maximum Power Point Tracking) controller continuously optimized input—I watched the LCD fluctuate between 65-95W as clouds passed. On partly cloudy days, expect 6-7 hours for a full charge.
The MPPT controller handled voltage fluctuations smoothly, unlike cheaper PWM controllers that interrupt charging when input varies. This matters for real-world solar conditions.
💡 Pro Tip: For backpacking, the SolarSaga 100W panel adds 4.4 lbs—bringing total system weight to 11.5 lbs. For basecamp trips where weight matters less, this combo provides indefinite off-grid power. For ultralight backpacking, charge fully before departure and skip the panel.

What Makes the Jackery Explorer 300 Different
True Backpack Portability: The 7.1 lb Advantage
Most “portable” power stations require vehicle transport. At 7.1 pounds, the Explorer 300 is genuinely backpackable—lighter than many DSLR camera setups and comparable to carrying an extra 2 liters of water.
I’ve carried it on 8-mile day hikes along Lake Michigan’s shoreline without noticing the extra weight. That’s the real differentiator here—this is a Jackery portable power station you’ll actually bring with you, not leave in the truck.
The 9.1 × 5.2 × 7.8 inch dimensions fit inside most 40L+ backpacks with room for other gear. The integrated handle folds flat for packing.
60W USB-C PD: Laptop-Class Charging Power
The 60W USB-C Power Delivery port is a game-changer for this size class. It provides bidirectional charging—you can recharge the Explorer 300 itself through USB-C while simultaneously topping off your laptop.
During my Sleeping Bear Dunes photography trip, I charged my MacBook Air from 20% to full while the Explorer 300 still had 58% capacity remaining. Most competitors in this weight class max out at 18-30W USB-C.
This also enables dual-input charging: connect both the AC adapter AND a USB-C charger to hit 80% in approximately 2 hours. Critical when packing the night before an early trailhead departure.
Pure Sine Wave AC: Safe for Sensitive Electronics
The two AC outlets deliver 300W of pure sine wave power—the same clean electricity your home outlets provide. This matters for sensitive electronics like camera battery chargers, laptops, and drones.
Cheaper modified sine wave inverters can cause:
• Buzzing from fans and motors
• Flickering LED lights
• Reduced efficiency and excess heat
• Potential damage to sensitive chargers
I’ve run Sony, Canon, and DJI chargers through the Explorer 300 without any issues. The pure sine wave output is essential for photographers and content creators.
What Can the Jackery Explorer 300 Actually Power?
Let’s be realistic about the 300W limitation. This Jackery 300 isn’t designed for high-draw appliances—it’s optimized for efficiency with personal electronics and small devices.
| Device | Wattage | Estimated Runtime/Charges |
|---|---|---|
| Smartphone | ~15W | 20-25 full charges |
| Laptop (MacBook Air) | 30-60W | 4-5 full charges |
| Drone Battery (DJI) | ~50W | 5-6 charges |
| CPAP Machine | 30-50W | 6-9 hours |
| Camera Battery Charger | 15-25W | 15-20 charges |
| LED Camp Lights | 5-15W | 25-50+ hours |
| 12V Mini Cooler | 40-50W | 5-7 hours |
| Portable Fan | 10-30W | 10-25 hours |
What it WON’T run: Hair dryers (1,000-1,800W), electric kettles (1,000-1,500W), space heaters (750-1,500W), full-size refrigerators (100-400W but often exceed 300W surge), power tools, or anything exceeding 300W continuous draw.

Jackery Explorer 300 FAQ
Can the Jackery 300 power a CPAP machine overnight?
Based on my testing with a ResMed AirSense (drawing approximately 30-35W with humidifier off), the Explorer 300 provides 8-9 hours of runtime—sufficient for single-night camping trips. With humidifier enabled (adding 10-15W), expect 5-6 hours. Multi-night trips require solar recharging during the day or stepping up to a higher-capacity unit like the Explorer 1000 v2.
Can I charge the Jackery 300 while using it?
Yes, the Explorer 300 supports pass-through charging. You can charge the unit via AC or solar while simultaneously powering connected devices. This is invaluable when you have brief access to power but need to keep devices running. However, Jackery recommends avoiding continuous pass-through use as it can accelerate battery wear over time.
Can I use the Jackery 300 in the rain?
No. The Explorer 300 has no official IP rating for water resistance. Keep it protected from rain and moisture at all times. I store mine in a dry bag during kayak trips and always keep it inside the tent during rainy camping nights. The ports and LCD screen are particularly vulnerable to water damage.
How many years will the Jackery 300 battery last?
Jackery rates the Explorer 300 for 500+ charge cycles to 80% original capacity. With average use (weekly charging), that translates to roughly 8-10 years of service life before noticeable capacity degradation. Store at 50-80% charge when not in use to extend longevity. Note: The newer Explorer 300 Plus uses LiFePO4 chemistry with 3,000+ cycle life.
Can I bring the Jackery 300 on a plane?
No. At 293Wh, the Explorer 300 exceeds the FAA’s 100Wh carry-on limit for lithium batteries (and the 160Wh limit available with airline approval). It cannot be checked or carried on commercial flights. For air travel, you’ll need a sub-100Wh power bank. This applies to all power stations in this capacity class.
Will third-party solar panels work with the Jackery 300?
Yes, the Explorer 300 works with third-party solar panels as long as they use a compatible connector (8mm DC barrel) and output within the unit’s input range (12-30V, up to 100W). I’ve tested with several off-brand panels successfully. However, Jackery’s SolarSaga line is optimized for their MPPT controllers and typically delivers the best efficiency.
Should I get the Jackery 300 or 300 Plus?
The Explorer 300 Plus (newer model) offers LiFePO4 battery chemistry for significantly longer cycle life (3,000+ cycles vs 500+), slightly different port configuration, and improved charging speeds. The original Explorer 300 reviewed here uses standard lithium-ion but remains an excellent value, especially during Black Friday sales when the bundle drops below $300.
Does the Jackery 300 work in freezing temperatures?
During my testing at 28°F (Wilderness State Park), the Explorer 300 experienced approximately 8% phantom drain overnight—acceptable for lithium-ion chemistry. Output remained stable even when cold. For best performance in freezing conditions, keep the unit in your tent or shelter to maintain temperature. Charging efficiency decreases significantly below 32°F.
How fast can I recharge the Jackery 300?
Dual-input charging is fastest: connect both the AC wall adapter AND a 60W USB-C charger simultaneously to reach 80% in approximately 2 hours. AC-only charging takes about 3.5 hours for a full charge. Solar charging with the SolarSaga 100W panel takes 5-6 hours in optimal conditions. The USB-C bidirectional capability makes the Explorer 300 uniquely flexible.
Can the Jackery 300 run a mini fridge or cooler?
12V thermoelectric coolers (40-50W draw) can run for 5-7 hours on a full charge. However, compressor-based mini fridges often exceed 300W during startup surge even if their running wattage is lower—causing the Explorer 300 to shut off for protection. For reliable fridge/freezer operation, a higher-capacity unit like the Explorer 1000 v2 with its 3,000W surge capacity is a better choice.
Is the Jackery 300 good for power outages?
For keeping phones charged, running LED lights, and powering communication devices during short outages (24-48 hours), the Explorer 300 is excellent. It’s silent, safe for indoor use (no CO emissions), and ready instantly. However, it won’t run refrigerators, space heaters, or high-draw appliances. For serious emergency backup, pair with solar panels or consider the Explorer 1000 v2 for larger loads.
